MATTRESS-FILLIN G MACHINE.

Specification of Letters Patent.

Patented July 28, 190s.

Application filed December 4, Serial N o. 405,005.

To all whom it may concern:

Be it known that I, EMIL ZoFNAss, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Mattress-Filling Machines, of which the following is a specification.

My invention relates to mattress filling machines and its object is to provide certain improvements in mattress filling machines of the character set forth in Letters Patent of the United States N o. 656,833 dated August 28, 1900.

Said improvements will be hereinafter described and pointed out in the claims.

In the accompanying drawings, in which like parts are indicated by like reference numerals,-Figure 1 is a side elevation of the front end of a mattress filling machine containing certain embodiments of my invention 3 Fig. 2 is a plan and sectional view on broken line 2 2 of Fig. 1; Fig. 3 is a sideI elevation of the rear end Aof said machine; Fig. 4 is a plan view of the rear-end of said machine; Fig. 5 is a side elevation of the ticking holder presently to be described; Fig. 6 is a detail View showing an elevation of the end of part of said ticking holder; and Fig. 7 is a detail view of one of the cross members of said ticking holder.

The frame of the machine consistsof uprights 1, 1, suitable horizontal bars as 2, 2, and the longitudinal outer boards 3, 3. The boards 3, 3 are tapered at their front ends, as shown in Fig. 1 to admit of the arrangement of the feeding and compressing aprons presently to be described. At the front end of the machine a shaft 4 is 'ournaled in suitable bearings 5 secured to t e front u rights of the frame; and at the rear end of t e machine a shaft 6 is journaled in suitable bearings 7 secured to the rear uprights of the frame, at the same level with shaft 4. Said shafts are provided with sprocket wheels 8, 8, carrying the endless chains 9, 9 ,-one at either side of the machine, extending between the front and rear shafts 4 and 6.

as shown, and adjacent tothe inner side of said apron for such distance along its oper ative stretch as is desired. As many rows of these rollers may be employed as desired, but under ordinary conditions two rows will be found satisfactory. The row or rowsof rollers may extend toward the rear of the machine as far as desired, but I have found it sufiicient to extend them back to a point where the compression of the filling material, when the machine is operating, first tends to cause sufficient friction between 'the apron and its support to create substantial heating between the moving parts. Without the use of friction rollers, especially near the delivery end of the machine where the compression is greatest, the parts tend so to heat that there is danger of fire. The lower apron is driven through pulley 13, receiving power from some external source, shaft 14 on which said pulley is mounted, s ur gear 15 onv shaft 14, spur gear 16 in mes with gear 15 and secured on shaft 4.

The u per apron 17, which is constructed like the ower apron heretofore described, is mounted on sprocket wheels 18 and 19 secured respectlvely tov shafts 20 and 21. Shaft 21 is supported by and j ournaled on a bracket 22 attached to one of the uprights of the frame of the machine. A frame work for the upper apron is provided by which the upper apron may be adjusted relatively to the lower apron, comprising bars 23 having bearings-24 at the rear end by which the bars are supported on shaft 21, and having bearings25 at the front end in which shaft 20 is supported and j ournaled. The upper and lower aprons converge toward the front end of the machine as shown, the upper apron inclining downwardly from rear to front. In order to vary the space between the delivery ends of said aprons, and thus vary the thickness or density of the mass of filling material as delivered,` and so adapt the machine for making mattresses of different thicknesses, the front end of the upper apron is vertically adjustable, the frame work carrying the upper apron swinging on shaft 21 as a pivot. This vertical adjustment is eected by screw shaft 26, mounted in a threaded lug 27 secured to the upri ht 1, and engaging at its lower end with aracket 28 fastened to the bar 23. A precisely similar device is pro- 'vided at the opposite side of the machine,

and both may be operated simultaneously b a chain and sproc et connection 29. Antii friction rollers' 30 arranged tandem are supported adjacent to the lnner side of the uper a ron 17 in a manner similarto the above .lengthwise throughout the'wh'ole length of the machine. These side boards are ta'- pered at 'their forward ends to fit between the converging aprons and are substantially similar in orm to the outer boards 3, 3 above described., f Side boards 31 31, are both laterally adjustable, simultaneously and equally toward or from each other, thus insuring that the work of com ressing and feeding the filling material'sha always be central of the machine, that is, symmetrical with relation to the central axis. The antifriction rollers therefore remain central or symmetrical with relation to the central axis of the work in whatever positionthe side boards 31, 31,

may be adjusted. At the delivery ends of the side boards 31, 31, are the brackets or arms 32, 32, extending forward'in front of the machine. The means by which the side boards are adjusted simultaneously and equally toward and from each other comprise cross shaft 33 journaled in suitable brackets 34 secured to some art of the machine as the boards 3, 3, said shaft 33 being-provided at one end with a ri ht handed screw threaded surface, and at lts other end with a left handed screw threaded surface, said screw threaded surfaces engagin respectively with correspondingly threade bores provided within hubs 35 on brackets 32. .At'one end of shaft 33 is aJ bevel gear 36, in mesh with bevel ear 37, secured at the end of shaft 38 journa ed on the framework of the machine,

. and extending from front to rear of the mai chine. At the rear end of the machine cross shaft 39 is provided journaled in suitable brackets 40 on boards 3 and having right and left-handed screw threaded surfaces coperating with screw threaded bores provided therefor inthe side boards 31 in a substantially similar manner to that above described with reference to the front shaft 33. Gear connection between shaft 38 and shaft 39 is provided consisting of bevel gears 41A and 42, and the intermediate shaft 43 journaled on bracket 40.

At some convenient point on shaft 38 its longitu inal axis, such as the spiral gear 44 mounted onbracket 45 secured to board 3, and spiral gear 46 secured to shaft 38, A crank handle`47 is provided for turning glear 44 which im arts a rotary movement to s aft 38 through tihe gear or screw46. When shaft means are (provided for rotating the same on 38 is rotated it imparts a rotary movement to both front and rear shafts 33 and 39 which in turn cause the side boards 31, 31, simulta-.. v

.and adjacent to the deliveryv end of the machine, expa'nsible and contractible in direce tion of the width of the machine. Eachof "the expansible and contractible side members comprises plate 48 and plate 49. Plate 49 has an upwardly extending projection 50 rovided with a slot 51. Plate 48 is bent ackwardly upon itself as shown at 52 so that the parts 48 and 52 embrace said projection 50. A headed stud 53 is mounted in part 52 registering with slot 51 through which the shank of the stud extends and under which the head of the stud is held. An internally threaded hub 54 engages with the correspondingly threaded end of the shank of stud 53 and is provided with a handle 55, by turning which the plate 48 may be clamped upon or loosened from the projection 50 at any desired point of adjustment Within the vertical slot 51. Thus the plates 48 and 49 may be vertically adjusted with relation to each other to expand or contract the ticking holder in depth. The projection 50 also extends be'- low plate 49 as well as'above plate 49 and is piv'otally secured at 56 to the sup orting arm 32. A curved slot 57 described) labout pivot 56 as a center, and a headed screw stud 58 mounted in the'part 50, admits of swinging the ticking holder upward and forward and of clamping it at any 'desired position of angular adjustment, thus affording convenient and rigid means for placing the ticking upon the tickin holder and thereafter swing-- ing the ticking older into operative position and there fastening it. c

It will be understood that the mattress ticking is placed on the ticking-holder in Van inside-out condition, the ticking being Acrimped or puckered in order to get it all on the tlckingolder that the closed end of the ticking is presented in an in side-out condition to the delivery end yof the machine, the ticking-holder belng in the position shown at Fig. 1; and that, as the mattress filling material is fed out of the machine, it causes the ticking to be reversed, the filled part of the mattress be'mg forced between theside plates and the cross rods of the ticking-holder. It is to facilitate the rapid'and easy placing` of the ticking on the tlcking-holder that the latter is pivoted to the. arms 32 to permit it to be swung upward and forward.

bers. are provided connecting respectively the Expansible and contractible cross meml ticking holder, the same ticking ho upper corners and the lower corners of the side plates of the tickinggholder adjacent to the delivery end of the machine. These cross members consist of inwardly projectingopposed rods and 61 secured to the op osite upper corners of said side members an connected by a telescoping sleeve 62. Sleeve 62 is of sufficient length to remain in engagement with and to connect rods 60 and 61 in all adjustments of the ticking holder from its position of contraction to its position of extreme expansion. i

It will thus be seen, that, Asince the ticking holder is supported by arms 32, 32, carried by the adjustable side boards 31, the ticking holder will be expanded or contracted automatically and simultaneously in Width with the lateral adjustment of the side boards 31, 31, the ticking holder thus at all times being of a width corres onding with the width of the compressed fling material and of the mattress to be stuffed. Noindependent adjustment of the ticking holder by the operator is required when assing from the manufacture of one size of) mattress to another size. It will also be seen that by reason of the adjustability in de th of the Fder can -be used by making a similar adjustment whenever the upper apron is adjusted vertically to stuff mattresses of varying thickness; whereas heretofore when varying -thevdimensions of the mattress it has been necessary to remove the ticking holder and substitute anotherone therefor of different size.

In order to drive the upper apron 17 which is vertically adjustable at its frontend, by mechanism which shall remain operative and shall not require adjustment when the apron is adjusted, I provlde a chain and sprocket drive connecting the rear apron shaft 21 whose location is fixed, with the driving shaft 14. This driving connection is shown in dotted lines in Fig. 1, sprocket wheel 66 being secured to shaft`14, s rocket wheel 68 secured to shaft 21, and c sprocket wheels The method of applying the ticking to the ticking holder and the general operation of the machine, excepting as hereinbefore specified, is substantially the same as described in said Patent No. 656,833 and no detailed description thereof is here necessary.
