MATTRESS-[FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 599,299, dated February 15, 1898.

Application filed January 15, 1897. Serial No. 619,879. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE F. MARTIN, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts,have invented new and useful Improvements in Mattress- Filling Machines, of which the following is a specification.

This invention relates to mattress-filling machines, and has for its object the production of a machine of the above class which shall be eflicient and powerful in operation, of inexpensive construction, and under easy control of the operator; and the invention consists of the construction and arrangement of the machine as set forth in the following specification and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a side elevation, partly in section, of a machine constructed according to my invention. Fig. 2 is a sectional plan View on line 2 2, Fig. 1. Fig. 3is a cross sectional View of the lower part of the machine on line 3 3, Fig. 2.

Referring now to the drawings, A A A A are four vertical posts forming the corners of a frame for the machine. A represents two longitudinal timbers united to said posts A at a suitable distance from their lower ends. A represents the longitudinal timbers uniting the upper ends of said posts A. One end of said timbers A projects for a certain distance beyond said posts A, as shown, for the support of the driving-shaft and clutch mechanism by which the machine is operated, and said projecting ends of the timbers A are supported by short posts A Suitable timbers B, between the posts A and 13, between the posts A, unite the two sides of the frame near the lower ends of the said posts, and similar pieces (not clearly shown) unite the upper extremities of the said posts, the whole constituting a rigid rectangular frame for the machine. A rigid floor C is laid between posts A in the said frame and constitutes the bottom of the box-like structure in which the material is compressed with which the mattress is to be filled. One end of said box is closed by the movable plunger D and the opposite end by the damper E, so called. Said damper, which is hinged at 2 on the frame of the machine, is provided with a weighted handle 3, by which it is kept in a vertical or closed position during the operation of compressing the 1nattress-filling and which is maintained by the same means in a horizontal position, as shown in Fig. 1, when the plunger D is operated to force the compressed filling into a mattress-tick. The sides of said box are formed of one fixed side a and one movable side a. The latter is adjustable transversely on the floor 0, whereby the machine is adapted to the compression of masses of filling for mattresses of various widths. The means for effecting said adjustment are shown in Figs. 2 and 3, and consist of a series of holes Z7, bored through the floor O, and a casting screwed onto the side of a, having a hole therein through which a pin 12' is passed, which engages one of the said holes I). Said adjusting devices may be applied in two or more places, as required, along the side of a. Fig. 3 illustrates this adjustment of the side a.

The compressing mechanism is constructed as follows: On shafts 4: and 5, suitably supported on the frame of the machine, are hinged the two compressing-platens F F by hinges 6. Said platens F and F have a re ciprocating movement vertically through. the arc of a circle of which said shafts 4 and 5 are the centers. Said platens are raised by means of the chains 7 for platen F and the chain 8 for platen F. A shaft 9, extending transversely across the top of the frame of the machine, has on one end thereof a gear 10, and is provided with the sprocket-wheels 12 for chains '7and 13 for chain 8, which sprockets are fixed on said shaft in any convenient mannen' Said sprockets are shown in plan View in Fig. 2 in dotted lines. A shaft 14 is supported in a bracket 15 at right angles to shaft 9 and has fixed thereon a worm-gear 16, which engages with the teeth of the gear 10. On said shaft 14 are two loose pulleys 17 and 18, driven in opposite directions by straight and cross belts from pulleys 19 and 20 on driving-shaft 21, supported parallel with said shaft 9 in suitable bearings on the extended ends of the timbers A, as described. Said shaft 21 is provided with a driving-pulley 22 and a clutch mechanism, whereby said shaft is made to rotate in either direction, which clutch mechanism is described farther on. Between the pulleys 17 and 18 on the shaft 14 are two friction-disks 23 and 24, having a common hub, all made in one piece and having a splineand-groove connection with said shaft, whereby said disks revolve with said shaft,but are movable longitudinally thereon. A lever 25 for imparting said movement thereto is pivoted on the bracket 15, and by a connecting-rod 26 between said lever, and a second lever 27, pivoted on the opposite end of the-frame, permits said friction-disks to be operated from either end of the machine to raise or lower the compressing-platens F and F. Said platens are raised, as described, by the chains 7 and 8. \Vhen the lever 25 is moved to the right by the rotation of shaft 9, which results from the contact of frictiondisks 23 with the side of the pulley 17, the worm 16 rotates gear 10 on said shaft and the sprockets 12 and 13 thereon to take up said chains and raise the platens.

When the mattress-filling has been spread on the floor 0 of the machine to be compressed and forced into a mattress-tick, the platens are moved down against said filling material, first by gravity and finally by pressure exerted by the chains 7, as follows: Under and parallel with the timbers A constituting the top of the sides of the frame of'the machine, are two timbers H, the adjoining surfaces of said timbers constituting a guide-slot in which two flanged wheels 28 run, only one of which is shown. Said wheels are fixed on opposite ends of a shaft 30, supported in the upper ends of two swinging arms 31, whose lower ends are supported on a shaft 32, having suitable bearings on a timber 33, secured transversely across the platen F, which serves to strengthen the latter and to support the bars 34, bolted to said transverse timber 33 and a second timber 33 parallel therewith. Said bars 34 are of such length as to project beyond the meeting edges of the two platens when they approach a horizontal position, whereby the said bars on F may reach over and bear upon a transversely-located timber 35 on platen F. The forcible depression of the platens F F is accomplished by carrying the chains 7 from eyebolts 36 in the bars 34 up and partly around the sprocket-wheels 12, and from thence to the shaft 30, to which said chains are secured. It will be seen by referring to Fig. 1 that the end of the chains 7 attached to eyebolts 36 slacks up and the end of said chains attached to shaft 30 is drawing when the shaft 9 is rotated in one direction and that the reverse takes place when the said shaft 9 is rotated in the opposite direction; and as arms 31 are never brought into a position at right angles to the horizontal position of the platens when the maximum compression of the filling has been attained, it follows that a draft on the chains 7, secured to said platens, forces said arms 31 back toward the hand-lever 27 by reason of rolling contact of said arms and the timber A through the flan ged wheels 28; yet said arms 31 hold said platens rigidly against the expansion of any material which may have been compressed by them because of the worm-andgear connection for driving the shaft 9, whereby said shaft is held stationary in whatever position it may be stopped. Chain 8, attached by one end to an eyebolt in the timber 35 on the platen F and passing around a sprocket 13 on a shaft 13 over one end of the frame, and from thence carried to and secured to the sprocket 13, serves to raise the platen F simultaneously with the raising of F by chains 7. Said chain 8 is given a little more slack than chain 7 in order that when shaft 9 is operated to raise the platens the platen F may start a little ahead of platen F, whereby the latter will not come in contact with the bars 34 on the former.

Means for moving the plunger D for forcing the filling in a compressed form into a mattress-tick consist of sprocket-chains 37, running over sprocket- wheels 38 and 39, the former on a shaft 40, hung in suitable bearings under the floor 0 of the machine near one end, and the latter, 39, on a shaft 41, supported in bearings on the extended portion of the timbers A, the last-named shaft having secured on one end thereof the bevel-gear 42. Movement is imparted to the said shaft 41 in opposite directions by the clutch mechanism on shaft 21. This mechanism in itself is not new and any of the various forms of reversing-clutches may be used in its stead, if desired. The clutch-lever 43 when it stands in the position shown in Fig. 1 holds out of engagement with either of the bevel-gears 44 or 45, the clutch-hub 46, which has a splineand-groove engagement with the shaft 21 and is movable by said lever 43, which can be thrown to the right or left to engage either one of the bevel-gears 21 to operate the shaft 41 to move the plunger D forward or to retract it after it has been so moved. Said forward-and-backward movement is imparted to the plunger D by the permanent engagement of stops secured in any convenient way to the frame of said plunger in proximity to said chains 37. In the drawings said stops are shown as consisting of two studs 47, bolted to the frame of the plunger and projecting downward through the links of the chains. The said chains 37 run in grooves 48, cut in the surface of the floor 0, to the end that they may be moved freely to operate the plunger D after the filling has been compressed by the platens, as described.

The clutch-operating lever 43 is provided with a connecting-rod 49, extending lengthwise of the machine and pivotally connected to a second operating-lever 43, secured to the frame of the machine at the opposite end from said clutch mechanism, whereby the latter may be operated from either end of the machine.

A spout S is secured to the cross-timbers B of the frame in any desirable way and is preferably of metal, and the tick T is drawn over the end of said spout in folds, as shown in Fig. 1, and retained there by any of the wellknown means employed for that purpose. The cross-sectional area of said spout S equals the similar area of the compressed mass of filling. The spout S is made adjustable transversely, whereby a uniform width of spout and box in which the filling is compressed may be maintained. Said adjustment consists in making the spout in two parts, one telescoping over the other, and when the movable end S has been adjusted relative to the fixed part S to the proper width, screws pass ing through the flange of the part S into the timbers 13 hold them in their proper relations the one to the other.

Automatic means for stopping the plunger D when it arrives at its limit of movement forward or backward consistin securing stops and 51 to the chain 37 nearest the shaft 21 and pivoting a lever 52 to the frame at 53, one end of said lever lying in the path of the said chain. In Fig. 1 the stop 50 (shown in dotted lines) is shown in the positionit would be in after having operated said lever 52 to stop the plunger D in the position in which it is shown in said figure. When said chain is again set in motion by the operation of lever 43 or 43 to expel the filling from the machine, the stops 51 travel in the direction of said clutch mechanism and reach and operate lever 52 by the time the plunger arrives at the end of its forward motion, whereby its said movement is arrested, and the manipulation of lever 43 or 43 again starts said plunger back toward the clutch mechanism, when its movement is again arrested, as described, by the contact of stop 50 with said shipping-lever 52.
