HNDLE FOR CROSSCUTESAWS.

SPECIFICATION forming part of Letters Patent No. 397,580, dated February l2, 1889.

Application filed May ll, 1888. Serial No. 273,587. (No model.)

.To all whom it Utr/zj concern:

Be it known that I, MARTIN BENNETT, a citizen of the l'fnited States, residing at Eureka, in the county of Ilnmboldt and State of California, have invented certain new and useful Improvements inIIandles for @ressent-Saws; and I do hereby declare that the following is a full, clear, and exact description of my said invention, reference being' had to the drawings that accompany and lforni part of this speeication.

My invention relates to handles for crosscut-saws; and it consists in certain improvements on the handle patented to me on the 3d day ol January, 1888, Letters Patent No. 375,916, and which have for their object to produce a more simple construction. as well as to provide a handle that readily adjusts itself to any saw-blade, as will be more fully explained hereinafter.

The following` description explains the nature ot' my said improvements and the manner in which I proceed to construct and carry out the same, the accompanyin drawings being referred to by Figures and letters.

Figure 'l is a side view ot' my improved handle applied to one end ot' a saw, a portion of the stock or wood portion of the handle and the end portion ol the saw-blade being shown. Fig. 2 is a top view of the clampplates, with detail of clamps shown separately. Figs. and al are outside and inside views of one of the clamp-plates, showing more particularly the construction and arrangement of the studs or pins that enter and hold the saw-plate. Fig. 5 shows a modicacation in the construction of the clamp, both jaws having holes or openings for the passage therethrough of a single pin or stud for holding the saw-plate. Fig. U shows a modification in the construction of th c clamp, whereby it is provided with a single pin or stud for entering and holding the saw-plate, instead of the two pins, as in other Iigures of the drawings. Fig. 7 is a cross-sectional view on the line fr] g/ ot Fig. S. Fig. S is a side view,

similar to that in Fig. '1, of the modified construction of the clampshown in Fig. (i.

Similar letters ot reference indicate corresponding parts in all the figures ot' the drawings.

My present improvement consists in certain construction and combination oi clamps having a socket to take the wooden bar or stock that forms the handle, and two jaws between which the end of the saw-blade is grasped and lfinally secured by the joint action o'l studs or pins on the end ot the clamps that take through holes in the saw-blaule,A and a bearing-block held between the two jaws against the end of the sawblade and secured in position by a clamp, bolt, and nut, the block being set between the jaws, and the bolt working through slots in the clamp, so that the block can be adjusted to the peculiar form or Character of saw and always brought up to a closeseat and bearing against its end. Adjustment of the studs or pins at the end of the clamps is also provided by a novel construction and arrangement ot shifting studs that form, also, afeaturc of this improvement.

Referring to the drawings,A represents the portion of a saw-blade at one end, and B BX the two jaws or parts ofV the clamp between which the saw is placed. v

C is the socket for the handle. Said socket C has an inwardly-projecting pin t shown in Fig. 2,) whereby it is more securely attached to the handle.

The two parts B BX' are slotted at CZ to let the clamp-bolt D through the two plates from one side to the other.

E is a bearing-block of suitable thickness to fit into and slide in the space l), provided between the two jaws, and furnished, also, with flanges E at top and bottom of suitable projection to ride on the edges of the plates. The block E is set in between the two jaws, and the bolt D, passing through the slots CZ, takes through an opening, e, in the middle of the block, the head D of the bolt having a bearing on the bach of one jaw and the nut D2 bearing against the back of the opposite jaw.

Figs. 5 and o illustrate a modification in the construction of the clamp for connecting it to the saw-blade. As above described, the clamp has been said to be provided with two studs vor pins that pass through the saw-blade; but in the modification shown in Fig. 6 the clamp is provided with a single pin, p, while in Fig. 5 both jaws have openings or holes through which a pin or stud may pass.

At a point in front of the block E a stud IOO or pimp, is lined on the inner tace of: one jaw, to take through the hole or perforation in. the saw-blade, that is generally provided for this purpose. For such vfastening means at the present time pins or rivets fixed solidly in the clamp and through the saw-blade are used; but l have :found in many instances, when applying my handles to blades of different manufacturers, that the holes provided :for these pins and rivets are not abvays in the same position with reference to the end of the saw-blades, nor always in exact line with each other, so that it becomes ditticult sometimes to set and tix the saw-handle in position at right angles with the line of the saw. Theretore, to accommodate different kinds ot' sawblades and compensate for any variations in the position of the holes for the studs or rivets, I have produced and make use ot' the fol.- lowing construction:

At the end of the j aw I form two slots, g g, inclined to the longitudinal center line oi' the clamp and converging toward the saw-engaging end thereof. Through these slots, from the outside, are set pins or studs H of suitable length to take into inclined. slots or recesses g]X gx, of similar character and equal inclination, in the opposite j aw. rlhe heads of these pins being enlarged to ride over the back edge of the slots gx, they are confined in place by a stop-plate, I, that is secured against the back oi' the jaw, after the pins are placed vin the slots, by means of a screwys. Sufficient space under the plate I is afforded to allow the studs to slide in their slot-s; but being thus confined they are kept from dropping out, while having suitable free movement. As

thus set and held, it will be seen that in any variation ot the holes in the saw-plate 'from the vertical line the studs will shift and adjust themselves to take through the holes and will come to a bearing in the opposite jaw. lVhen the block E .is brought up against the end of the saw and the clamp-screw is tightened, the blade will be Iirmly clamped and the handle kept in true position under all conditions and directions ot' strain and ttm-ces it is called upon to bear.

The construction shown in ligs. l and 2 has the clamp in two halves on separate pieces. l

Ilaving thus fully described my invention7 what I claim as new, and desire to secure by Letters Patent, is

l. In a handle for crosscut-saws, the combination of the slotted clamp-plates having sockets at one end, jaws to take the saw-blade at the other end, provided with a stud or studs to take through the saw-blade, and the sliding bearing-block and clamp-screw, arranged, substantially described, for operation as set forth.

2. In a handle tor crosscutsaws, the combination, with the clamp-jaws having the inclined slots or grooves, ot the studs or pins movable therein, the lmtring-block, and the clal/npscrew, all arranged to operatie substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
