" theline l2-l2 of Fig. 9.

As iswell `known the art, coasting sleds of ordinary length are constructed with four knees which are employed to connect the runners with the seat structure. On the other hand, when ooasting sleds are consiruoted. in the longer lengths, in order torisiclly support. the seatstrncture so as to prevent vertical flexing thereof, it is onstomary to employ six ;knees for oonneoting the runners to the seat structure- Sinoe the present inventioh is applioable to both types of sleds which it is composed, as will be hereinafter more fully described and claimed.

In the accompanying drawings:

with slight modification, in Figs. 1 to 8 inclusive, we have shown in what manner the invention oon beapplied to the siX-knee type of sled, and in Fies- 9 'to 12 inolusive, we have shown the inventon applied to the foure'knee type of sled.

Beferring to Fiss- 1 to 8 inclusive, Ithe improved sledvcomprises apair of side rails I I, l2 which are connected at intervals lov a p'lurality of oross 'bars l3, IA and |.5, said cross bars being rigidly fastened to said Side rails, by bolts or rivets 6.

Supported by the cross bars is a seat structure Il, preferably constructed from a plurality of hoaros which are fostened to the oross bars Joy Securing elements l'8, in the form of nails, tacks, rivets, bolte, and the like- As shown in Fie.- fi; in the present instance the boards are fastened to the cross bars hy nails.,

For holding the seat structnre in properly spaced relation to the runners V20 and 2I, which are of well .known form, and oonneoting the ports together, suitable knees 22, v23, 24, 25, 28 and 21 are ernnloyed.. The knees are arranged in pairs and constitutevbrackets which are preferably made of sheet metal and oomprisins downwardlydiverging less and a nat elongated top portion- The top portion '28 of the knee`2 2 is secured to the ,cross bar I 3 by a bolt or rivet 29,1 as shown in Fig- 6, said rivet being located adjacent to the outer end of said knee and constituting a piyot about which the knee is adapted to swing inthe manner to be hereinafter described. I

Likewise, the top portion 3,1 of the lsnee 2.34 is pivotally mounted ontheoross bar by a bolt or rivet 33.

The top portion 32 of the knee 24 is connected to a cross bar 33 by a pair of spaced Securing elements 34, 35, the element 34 being located at the outer portion of the knee 24, directly beneath the side rail H, and the element 35 being passed through a slot 36 formed transversely in the top portion 32 and located adjacent to the inner end of said top portion, as shown in Fig. 1.

Likewise, the knee 25 is similarly connected to the cross bar 33 by fastening elements 31, 38, arranged in a manner corresponding to the fastening elements 34, 35, respectively, the element 38 passing through a slot 39 formed in the top portion 43 of the knee 25.

The cross bar 33 is located to the rear of the cross bar l4, said cross bar 33 having its upper surface in contact with the underside of the seat structure and not connected to said seat structure.

During the operation of the steering mechainsm the cross bar 33 is adapted to move transversely with respect to the seat structure, as will be hereinafter described, said cross bar moving to the position shown by broken lines, Fig. 1. i

The top portion 4| of the knee 26 is secured to the cross bar |5 by the bolt or rivet |6, said rivet being located at the outer end of the top portion of said knee, as shown in Fig. 1. The inner portion of the top 4| is also secured to the cross bar |5 by a bolt or rivet 42 which is passed through a transverse slot 43 in the portion 4l.

Likewise, the top 44 of the knee 21 is` secured to the cross bar I5, by the rivet |6 and by a rivet 45, the latter rivet being passed through a slot 46.

Disposed on the underside of the cross bar |3 and pivotally connected thereto by means of a bolt or rivet 48 is a lever 49.

One end of the lever 49 is pivotally connected to the inner portion of the top 23 of the knee 22, as indicated at 56, Figs. 1 and 6. The other end of the lever 49 is pivotally connected, as indicated at 5I, to the overlapped ends of links or rods 52, 53. the front end of the sled and the link or rod 53 extends towards the rear of the sled.

Likewise, another lever 55, similar to the lever 49, is mounted on the cross bar. |3 by a pivot 56, said lever 55 having one end pivoted to the top 3| of the knee 23, as indicated at 51, and its other end connected by a pivot 53 to links or rods 55, 60 similar to the links or rods 52, 53, respectively, heretofore referred to. i

Pivotally mounted, as indicated at 62, to the cross bar 33 is a plate 63.

The pivot 62 is disposed midway the length of the cross bar 33, being located along the longitudinal center line of the sled when the runners 20 and 2| are straight.

The plate 63 is formed with five side edges and underlies the cross bar l4, as well as the cross bar 33, as shown in Fig. 1. Normally, when the parts are in the full line position shown, the

The link or rod 52 extends towards forward edge 64 of the plate 63 is disposed in The rear end of the link or rod 53 is pivotally connected, as indicated at 63, to the plate 53, the plate being formed with a slot 63 for the pivot pin 68.

Likewise, at the other side of the plate 63, the rear end of the link or rod 60 is pivotally connected to said plate by means of a pin 10 disposed in a slot 1l similar to the slot 69.

Disposed near the front of the sled and arranged transversely thereof, is the usual steering bar 13. The steering bar, which is of suificient length to project beyond the side rails il, l2 to f enable the Operator to push or pull on one end or the other thereof to steer the sled, is pivotally mounted to the center panel of the seat structure |1 by means of a bolt 14 located on the longitudinal center line of the sled (see Figs. 3, 4

and 5).

The forward end of the link or rod 52 is connected to the steering bar 13 by means of a pin or rivet 15, and the forward end of the link or rod 59 is connected to the steering bar by means of a pin or rivet 16.

The pivots 15 and 16 are located in spaced relation on opposite sides of the bolt 14, as shown best in Fig. 5.

The front ends of the runners 26, 2| are connected to a cross bar 18 by means of pins or rivets 19. The cross bar 18 is located beneath the steering bar 13, as shown in Figs. 4 and 5.

In addition to constituting means for connecting the forward ends of the runners, the cross bar 18 supports a plate 80. In plan, the plate 83 is slightly more than semi-circular in form, as shown in Figs. 1 and 3. In vertical longitudinal section, as shown in Fig. 4, the plate 86 is somewhat irregular in form. The main body portion of the plate which is connected to the cross bar 18 is located in a. lower plane than is the front edge portion 81, the two portions being connected by an intermediate inclined portion 82.

As shown in Fig. 1, the plate 86 is disposed between the front end portions of the runners 2D, 2| and extends a suitable distance forwardly therefrom. The plate underlies the front portion of the seat structure |1 and provides a means for closing the front end of the sled so as to prevent snow from passing upwardly through the open part of the structure towards the operator.

Fastened to the steering bar 13 by rivets 84, as shown 'in Fig. 4, and located along the longitudinal center line of the sled when the runners are straight, is an arm 85.

The front end of the arm is pivotally connected to the forward portion of the plate 80, by a rivet 86. In this way the plate also functions as part of the steering mechanism.

The forward ends of the boards of the seat structure l1 are made arcuate in form so as to fit snugly against the rear edge portion 88 of the front plate 89.

The plate 86 constitutes a bumper for the front of the sled. As shown in Figs. 4 and 8, the outer periphery of the plate 39 is in the form of an arcuate channel 90 of inverted U -form. The main body of the plate indicated by the reference numeral 89 is disposed in a lower horizontal plane than is the rear edge portion 88 and the upper fiat portion of the channel 96. The channel has a downwardly extending substantially vertical flange Bl. This flange is somewhat semi-circular in plan as shown in Fig. 1. The rear edge of the portion 88 of the bumper plate is also somewhat semi-circular in plan, as shown in Fig. 3. However, the curvature of the portion BBdiffers slightly from the curvature of the outer channel 90', and between these two portions of the plate there is a substantially horizontal web which isindicated by the reference numeral. 89. Thisweb is somewhat crescent Shaped. If so desired, openings 92 may be formed in the web of the front bumper plate 89.

The rear portion of the plate 89 is retained -in position with respect-to the front portion of the boards of the seat structure I'I, by means of a strap 93. The ends of the strap 93 are secured to the underside of the bumper -plate 89, and said strap extends beneath the boards of 'the seat'structure Il, as shown best in Fig. 4.

The outer peripheral portion or channel 90 of the bumper plate 89 is secured to the front ends of the side rails II, I2 by rivets 9-2, as shown in Figs. 3 and 5.

In this way the bumper plate -89 is rigidlyconnected to the main body of the sled and serves as means for protecting the front end thereof.

It is believed it will be -readily apparent from the foregoing description taken in connection with the drawings that the sled may be steered in either direction as desired by pushing on one end or the other of the steering bar 13.

When the steering bar T3 is moved towards the position illustrated by broken lines, Fig. 1, a for- Ward pull is exerted on rearward push is exerted on the link or rodl'i.V

Since the rear end of the rod 52 is connected to the inner end of the lever 49, when said rod is thus pulled forwardly, the lever is turned on the pivot provided by the rivet 48, and due to the manner in which said lever is connected to the runner knee 22, said knee is turned towards the position indicated by the broken lines, Fig. 1.

When the rearward push is exerted'on the rod 5d by the steering rearwardly on the pivot provided by the rivet 55, and consequently the runner knee 23 is turned towards the broken line position' illustrated in Fig. 1.

The pull exerted on the rod 52 is transmitted to the rod 53, and the rearward push exerted on the rod is transmitted to the rod 60 so that the plate os is turned on the pivot 55.

Due to the manner in which the plate 63 is constructed and the manner in which said plate is connected to the cross bar 33, the cross bar 33 is moved by the plate E3 laterally or transversely of the seat structure i'I towards the position :shown by the broken lines, Fig. 1. Since the knees 24 and 25 are secured to the cross bar 33, the knees will also be shifted laterally.

When the steering bar 13 is operated in the manner above described, the arm 85 is swung about the center provided by the bolt 14, and since the outer end of said arm is pivotally connected to the plate the plate will be shifted laterally or transversely and since said plate is connected to the front ends of the runners 2Il, 2I, the front ends of the runners will be moved.

As shown in Fig. 1, the lateral movement of the cross bar 33 is in the opposite direction to the lateral movement of the plate 80. In this manner the runners are bent, as indicated by the broken lines.

Although the leverage mechanism for flexing or bending the runner extends from the steering bar Is rearwardly to the intermediate portion of the sled, due to the manner in which the leverage mechanism is constructed and operates, as :has been heretofore described, it is possible withbut bar 13, the lever 55 is swung 'A the link or rod 52, and a I aminimum of effort to fiex the runners for their entire length. In this manner much sharper and quicker turns can be made than with the older types of sleds.

In the form of the invention shown in Figs. 9 t0f12, inclusive, the improved sledfcomprises a pair of| side rails III and II2, which are connected at intervals by a pluralityr of cross bars II3, HA and II5, said cross bars being fastened to said side rails Iby lb'olts `or rivets I I'.

:Supported by the cross bars is a seat structure II'I, preferably constructed from a plurality of boards which are fastened to the cross bars by Securing elements I f, in the form of nails, tacks, rivets, bolts, and the like. As shown in Fig. 11, in the present instance the boards are fastened to 'the cross bars by nails.

For' holding the seat structure in properly spaced relation to the runners I2fI and |2 I which are of Well-known form, and connecting the parts together, suitable knees I22, I23, I24 and I25 are employed. The knees are arranged in pairs and constitute brackets which are preferably made of sheet metal and comprising -downwardly diverging legs and a flat elongated top portion.

The top portion I28 of the knee |22 is secured to the cross bar II3 by a bolt or rivet I29, as shown in Fig. 11, said rivet being located adjacent' to the outer end of said knee and constituting a pivot about which the knee is adapted to turn when the steering mechanism is operated.

Likewise, the top portion I3I of the knee I23 is pivotally mounted on the cross bar I I3 by a bolt or rivet ISO.

The top portion I32 of the knee IM is connected to the cross bar II5 by the rivet IIB (see Fis. 12).

Likewise, the knee to the cross bar II5.

Disposed on the underside of the cross bar |I3 and pivotally connected thereto by means of a bolt' or rivet M8, is a lever Its.

One end of the lever M9 is pivotally connected to the inner portion of the top |28 of the knee l22, as indicated at I50, Figs. 9 and ll. The other end of the lever M9 is pivotally Vconnected, as indicated at ISI, to the end of a link or rod- I52.

'Between the pivots M8 and I5I, the front end of a link or rod I53 is pivotally connected to the lever I49, as indicated at I54.

The link or rod |52 extends from the lever M9 towards the lfront end of the sled where it is connected to the steering mechanism in the manner to be hereinafter described.

The 'link or rod I53 extends from the lever Mo rearwardly and its rear end is pivotally connected to the inner portion of the knee IM, as indicated at I68,`Figs. 9 and 12.

Another lever I5'5, similar to the lever M9, is mounted on the cross bar II3 by a pivot I55, said lever I55`having one end pivoted to the top |3I of the knee l23, as indicated at I5'I, and its other end connected by a pivot I'58 to a link or rod Iii), similar to the link or rod I52.

Between the pivots I5'I and I53, the front end of alink or rod I is pivotally connected to the lever I55, as indicated at ISI.

'The link or rod I59 extends from the lever I55 towards the front end of the sled, and the link or rod ISO extends from the lever I-55 rearwardly and its rear end is pivotally connected to theinner portion of the knee I25, as indicated at 16,2;

Disposed near the front of :the sled and I25 is similarly connected arranged transversely thereof, is a steering bar l'l3 which is pivotally mounted to the center panel of the seat structure ll'l by means of a bolt IM.

The forward end of the link or rod |52 is connected to the steering bar 113 by means of a pin or rivet ll, and the forward end of the link or rod I 59 is connected to the steering bar by means of a pin or rivet 3.

The pivots |75 and HS are located in spaced relation on opposite sides of the bolt I 15, as shown in Fig. 9.

The front ends of the runners |2EI and l2| are connected to a cross bar HB by means of pins or rivets 179. The cross bar 8 is disposed beneath the steering bar 113, as shown in Fig. 10.

In addition to constituting means for connecting the forward ends of the runners, the cross bar 118 supports a plate IBO.

As shown in Fig. 9, the plate 180 is disposed between the front ends of the runners and extends a suitable distance forwardly therefrom.

Fastened to the steering bar |13 by rivets |84 and projecting forwardly therefrom, is an arm N35.

` The front end of the arm IBS is pivotally connected to the forward portion of the plate l8, by a rivet let. In this way the plate l8ll functions as part of the steering mechanism, as well as providing means for preventing snow from entering the cracks between the pieces of the body structure H'l of the sled.

The front ends of the boards ll'l are made arcuate in form so as to fit snugly against the rear portion of an arcuate front plate or bumper S89 which is secured to the front ends of the side rails IH and ll2 by rivets l94.

The front bumper plate |89 is constructed and mounted on the front of the sled in a manner similar to the plate 89 heretofore described.

In operation, when the steering bar |13 is moved, for instance, towards the broken line position shown in Fig. 9, a forward pull is exerted on the link or rod 152, and -a rearward push is exerted on the link or rod 59.' At the same time, the arm |85 is turned on the pivot 114.

Since the rear end of the rod |52 is connected to the inner end of the lever M9, when said rod is thus pulled forwardly, the lever M9 is turned on the pivot M8, and due to the manner in which said lever is connected to the runner knee 22, said knee is turned towards the rear of the sled, as indicated by the broken lines, Fig. 9.

Since the knee |24 is also connected to the lever M9 by link or rod |53, the knee 124 is turned about the pivot HG but in a direction opposite to the direction in which the knee |22 is turned about its pivot.

When the rearward push is exerted on the rod E59 by the steering bar 3, the knee |23 is turned towards the front of the sled and the knee l25 is V turned towards the rear of the sled, as shown by the broken lines, Fig. 9.

Since the outer end of the arm l85 is pivotally connected to the plate IBO, when said arm is swung about the pivot provided by the bolt l14, the plate Will be shifted laterally or transversely, and since said plate is connected to the front ends of the runners |20 and l2l, the front ends of the runners will be moved.

In this manner the runners 20 and |2| 'are bent or fiexed laterally, as indicated by broken lines. The mechanism imparts to the runners an easy or gradual curve which extends the entire length of the runners.
