MACHINE FOR STUFFlNG MATTRESSES.

SPECIFICATION forming part of Letters Patent No. 597,446, dated January 18, 1898.

Application tiled July 24, 1897.

To a/ZZ whom it may con/cern.-

Be it known that I, WILLIAM TUCKER, a

' citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for Stuffing Mattresses, of which the following is a speciiication. l

The object of this invention is to enable the materialwsuch as hair, husks, cotton, excelsior, and the like-with which mattresses are filled to be laid out in uniform thickness and of either uniform material or of layers of diver-sided material, according to requirements, and then compressed a predetermined amount and deposited in the cloth envelop or tick in this compressed condition without bunching o'r disturbing the mass.

Another object of the invention is to provide a machine which will automatically compress the filling material, deposit it in the cloth covering, and return again into position for a new discharge; and the further object of the invention is to provide a machine which can be set to iill mattresses of different widths, thicknesses, and different densities of material and to provide a machine which will be easily repaired and free from danger to the operator. A

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which-- Figure l is a view in longitudinal vertical section of my machine, showing the truck onto which the filled mattress is deposited and showing a mattress partially lilled; Fig. 2, a

View in side elevation of my machine, showing the frame broken away in part at the driving end and showing the machine ready to commence the operation of lling a mattress; Fig. 3, a horizontal section on the line 3 3` of Fig. 2 looking in the direction of the arrows and showing the bottom of the box broken away in part to show the underlying mechanism 5 Fig. et, an end elevation of the machine looking in the direction of the arrow 4: of Fig. 2; Fig. 5, an end elevation, partially in sec- Lion, of the driving end of the machine looksein In. 645,849. oro man.)

G, a transverse vertical section on the line 6 6 of Fig. 2,' showing the bed as containing the iilling material with the lid resting on and compressing the material and showing the gate open; Fig. 7, a detail in plan view of the lid, showing the braces whereby a parallel lateral movement is secured to the adjustable sections of the lid; and Fig. S is a detail in perspective of one of the front vertical posts and its attached levers.

Similar letters of reference indicate like parts throughout the several views of the drawings.

The frame which supports the mechanism of my device comprises the four vertical posts A and two shorter posts A', which are connected by transverse horizontal braces A2 and longitudinal horizontal braces A3, the exact construction of which frame is immaterial so long as it is suiticiently strong and rigid to stand the strain which it will be called upon to bear. l

B represents the bed, inside of which the material for filling the mattress is distributed. The horizontal position of the bed is fixed, but it is adj ust-able in width in the manner as will be'hereinafter fully described. The bed at one of its ends opens into a four-sided mouthpiece C, which tapers outwardly and is adjustable in width and height conformably with the dimensions in cross-section of the proposed mattress, as will also be hereinafter described. The cloth covering for the mattress is drawn onto this mouthpiece.

D is a lid which has reciprocating Inovement and is adapted to descend into the bed and compress the mattress material which has been previously deposited therein.

E is a plunger which pushes the compressed filling into the cloth covering and forces the latter oft of the mouthpiece as it is filled, depositing the mattress on the truck F, where- .by by moving the truck along the track'F the mattress can be readily carried to a sewing-machine and the open end of the cover sewed up and the truck returned in time to receive the next mattress as it comes from the iillingimachine.

Referring now to the bed in which the tilling for the mattress is iirst deposited, B are the side boards, which rest on the lateral braces of the frame and are each bolted to the `upwardly-cranked ends of a pair of inwardlyprojected horizontal rack-bars G. The two opposite rack-bars at each end of thebed have the teeth on their adjacent sides, and the bars are placed close enough together to engage the teeth on a pinion` G', which is placed between them. 'Vhen the pinions are rotated,

the rack-bars will be moved in opposite directions to each other. Mounted on the vertical shafts G2, which carry the pinions G, are the sprocket-wheels G3 of equal diameter, and G7 Vis a chain belt connecting the two sprocket- One of the shafts has the additionalv wheels. sprocket-wheel G4, whichk is connected by the Vchain belt G5 witha sprocketfwheel G6 on the shaft GS. The upper end of the last-mentioned shaft has ahand-wheelat its upper end, by which it is rotated. Y Bythemechanism as thus described both of the side boards B can be moved simultaneously in opposite directions by turning the hand-wheel.

The bottom of the bed comprises the longitudinally centrally slotted stationaryboardk B2 andthe laterally-adjustable pieces B3, placed between the center board B2 and the side boards B. ber on each side of the center board.) The pieces are kept equidistant from each other same movement to the similarly-constructedV lid. The arrangement of the levers issimi lar tothe construction used in what is well known as lazy-tongs,7 with the addition that the same pivot which connects the intersecting levers also connects the levers with the pieces B3.

As shown in Fig. 6, the side boards B have inside bottom anges ZJ, and the spaces between these flanges, the pieces B3, and the center board are closed by the sheet-metal strips or plates b', which have one of their longitudinal edges secu red to one of the strips or a flange, while their loose edges rest upon and overlap the next inside strip, with the innermost one resting on the center board, thereby providing an expansible bottom. The mattress-filling is laid out in even layers on this bottom, the distance between the side boards' being previously fixed to suit the width of the proposed mattress. The next step is to compress the filling material, and this is accomplished by forcing the lid D down onto the mass contained inthe bed, the lid in its normal position heilig sufficiently elevated to afford free access in placing the .filling material in the bed. The posts A serve as guides. Mounted at their upper ends are the transverse shafts H, which terminate at each of the four ends of the shafts with the sprocket-wheels h. Securedvto the posts A a suitable distance below are the brackets h', which support the sprocket-wheels h2. Chain belts H2 connect the upper and lower sprocket# wheels on the same post together. The lid (Here shown as three in num-V D is connected to these four chains, whereby Vthey will carryrthe lid up or down, according to the direction of movement of the belts. I will first describe the construction of the lid and then the mechanism by which the movement of the lid is controlled.

The longitudinal pieces d d and two transverse pieces d ci constitute a frame, of which the pieces (Z (l are against theY inner side of the posts A and the transverse pieces d' d are long enough to contact'with the sides of they posts A at right angles to the sides of the posts against which the longitudinal pieces have their bearings, as shown in Fig. l. Secured to the kunder sidek of the frame thus formed are the transverse supports d3 (Z3, from it and are connected therewith by the crossed f andpivoted levers Z, as shown in Fig. V7. The two outside ones of the adjustable pieces D' are provided with the hooks d, which, when the lid is lowered into the bed, engage the side boards B. Then itis desired to change the width of the bed and of the lid to correspond with it, the lid is first lowered into the bed and then bythe action of the hooks when the width of thebed is changed the lid will be changed in width tofit.

Metal fingers D3,

IOO

rbolted to the frameand engaging theV chain belts, cause the l/id D to travel up and down with the corresponding movement of the belts.

The mechanism for driving the shafts H, which actuate the chain belts controlling the movement of the lid D, will now be described.

I is a shaft mounted longitudinally of the machine above the shafts H and having a worm t at each end to engage the cogs of the toothed Wheels 'i2 on the shafts H.

I is a collar, with both ends notched to form the halves of two oppositely-acting clutches. The collar loccupies a fixed position on the shaft.

12 and Pare pulleys mounted loosely on the shaft I on opposite sides of the collar I. Their hubs adjacent to the collar are notched to form the opposite halves of clutches, which work into the other clutch-half provided by the collar.

J is a line-shaft driven by any convenient motor. It carries driving-pulleys, one of which is connected by a straight belt with the pulley l2 and another by a crossed belt with the pulley I3, whereby a like and a reverse movement can be transmitted from the line-shaft J to the shaft I. The pulleys I2 and 'I3 are shifted by the levers K2 and K3, which levers are pivoted to the frame of the machine and are drawn by the'springs 7c and 7c in the direction to disengage the pulleyhubs from the collar I. In the construction as here shown when the shaft I is revolved IIO by means of the lever e9.

by the pulley l3 the direction is such as to lower the lid. Pivoted to the end of the lever K3 is the shifting-bar K4, which Works through a vertically-slotted guide k7. The bar K4 has a notch to engage the top of t-he guide and hold the bar from longitudinal movement when the lever is in the required position to couple the pulley with the collar, and a spring les draws the bar up and holds the notch against the guide; but the moment the guide is out of the notch the spring 7c', acting on the lever K3, uncouples its pulley, thereby of course stopping the descent of the lid.

L is a lever which is pivoted to the end of the shifting-bar K4 and is fulcrumed to a fixed pin L', and the lower end of the lever has an adjustable plate Z, which stands in the path of the transverse bar d of the frame of the lid. The lever is slotted longitudinally at its fulcrum for the passage of the pin lj,

whereby when the frame of the lid strikes the plate Z the shifting-bar K4 will be drawn down and its notch disengaged from the guide. As the amount of compression imparted to the contents of the bed depends on the travel of the lid, and as this will be controlled by the contact with the plate Z, it is obvious that a vertical adjustment of the plate provides means for regulating the pressure. To this end the plate will be secured to the lever by a bolt Z', and the bolt will be projected through a longitudinal slot in the plate, which enables the plate to be raised or lowered. A graduated scale, as shown, will enable the plate to be set for mattresses-of di'lferent thicknesses as well as density.

As the returnof the `lid to its highest ele* vat-ion occurs only after the filling has been pushed ont of the bed into the tick, and that operation depends somewhat on the mechanism for operating the pl un ger, the latter mechanism will be next described.

E represents two non-revoluble parallel shafts mounted in the saine horizontal plane close under the bed of the machine. These shafts pass through boxes in the head E2 and serve as guides for the head, which has a reciprocating travel along the shafts, iinpelled by the link belt E2. Sprocket-wheels e and e', mounted at opposite ends of the machine, give support to the chain belt E2. Thewheel e is mounted on the revoluble shaft e2, and the shaft e2 also carries the toothed wheel es, which mesh es with the worm c4 on the shaft e5. The shaft e5 has the two loose pulleys e and e7, the former of which is driven by a straight belt from a pulley on the lineshaft J and the latter by a crossed belt from an additional pulley on said line-shaft. While the pulleys e6 and e7 are loosely mounted on the shaft c5, they are secured against longitudinal movement, andbetween them is the slidingclutch e2,which is splincd to the shaft and can be thrown into engagement with the notched hub of either one of the pulleys or disengaged from both The lever e2, as

shown in Fig. 3, is pivoted to the frame of the machine and is connected with the sliding bar n M, whereby when the bar M is moved longitudinally the lever will be shifted. When the lever is shifted so as to cause the pulley e5 to drive the shaft e5, the chain belt E3, which is connected with the under side of the head E2, will be driven in a direction to cause the head to travel along the shafts E'toward the front of the machine, and when the lever is shifted in the opposite direction to cause the shaft e5 to be driven by the pulley e7 the direction of movement of the chain belt ES will be reversed and the head E2 will travel back to the starting-place at the driving end of the machine. Secured to the head E2 is the upwardly-projected plate E4, which enters the longitudinal slot formed lin the board B2 of the compres sion-bed, and bolted to the plate above the bottom of the bed is the horizontal bar E5, having the cross-head E6, to which the plunger-board E is bolted. The board E is removably secured, whereby it can be removed and boards of different width and length substituted when the machine is set to fill different-sized mattresses.

E7 are diagonal braces to stiften and strengthen the cross-head, and ES is a flange which is projected from the front end of the bar E5 down into the slot in the board B2 of the bed of the machine. The flange Es increases the bearing in the slot, thereby preventing unequal side pressure on the plunger from breaking its supports or causing the mechanism of the plunger to bind.

N is a hand-lever which is pivoted to the frame of the machine and to the front end of the sliding bar M, and by moving the sliding bar toward the driving end of the machine the lever c9 will be shifted, whereby the con nected mechanism will cause the head E2 to begin its travels, and I will now describe the mechanism by which the direction of movement of the head will be automatically reversed' when it reaches the front end of the bed and automatically stopped when it reaches the place of beginning at the driving end of the'machine.

M is a striking-bar secured to and moving with the head E2, and m and 'm' are lugs fixed to the bar and projecting up into the path of the bar M. Their position on the bar is such that the longitudinal movement given to the bar will throw the pulley on the shaft e5 out of gear and stop the head E2 just at the right place, where the change in the direction of the stroke is desired or where it is Idesired that the head should stop at the end of the return movement. The striking-bar M', acting on the lugs m and m', only serves to stop the rua-- IOO IIO

machine and has an inclined downward eX- tension 19, which bears against a roller R,

mounted on the sliding bar M. The loose end of the lever Pis drawn down by the spring P with sufficient vforce to move the bar longitudinally by the action of the inclined extension against the roller. l/Vhen the sliding bar M (see Fig. 2) is first moved by the lever N, the roller R raises the lever and assumes the position under the extension p, as shown in Fig. I, and then the pull of the spring on the lever is resisted by the horizontal end of the extension resting on the roller, as shown, which condition remains unchanged until the striking-bar M, by striking the front lug m, moves the sliding bar M forward and leaves the roller R in contact with the sloping side of the extension p. Then the action of the spring P forces the bar M an increased distance sufficient to move the lever e9 and bring the pulley e7 into action, which reverses the direction of movement of the head. At the same time that the plunger and the head which carries it are moving back after the plunger has done its work it is desirable that the lid, which has been down until this time, should move up to allow the bed to be refilled. This will be accomplished by throw- A ing the pulley I2 into engagement with the clutch, which transmits its movement to its shaft, and I will now describe the automatic means for doing this.

A is an extension of the frame of the machine, which forms a support for the pin L', and between the lever L and the extension A6 is a lever T, which is also fulcrumed on the same pin L which forms the fulcrum for the lever L. The lever T is connected with the lever K2 by means of the shifting-bar S.

W is a rocking shaft mounted transversely of the machine and having two crank-arms w and w. The arm w is connected by the bar 'w' with the lower end of the lever T, a series of holes being provided in the end of the bar and of the lever for the pivotal bolt, whereby an adjustment of the parts can be secured.

V2 is a horizontal lever which is pivoted to one of the longitudinal braces of the machineframe. The short outer arln of the lever is connected with the crank-arm 'zu' by means of the connecting-rod w3, and the long inner arm of the lever projects into the path of theV striking-plate U, which is a lateral projection from the head E2. The lever W2 is placed where the striking-plate will act on it when the head is at the end of its stroke at the front of the machine, and the movement imparted to it will couple the pulley I2 to the shaft I and cause the lid to ascend by the mechanism thereby set in motion. The spring s, acting on the lever T, and the spring 7o, acting on the lever K2, have a combined effect of uncoupling the pulley 12 from its shaft I, and as soon as the head E2 has moved on its return far enough tol release the lever NVZ from the action of the striking-plate the force of the springs s and 7c will act and stop the hoisting mechanism of the lid before the raising of the lid is completed. To avoid the premature arrest of the lid, I provide the notched lever W", which is drawn down by the spring 109 and hooks over the upper end of the lever T and locks itagainst the action of the springsuntil the frame of the lid reaches the lever W7, and by elevating it in the manner shown in Fig. 2 releases the lever T, thereby allowing the springs to act and stop the machine.

Y is a gate which temporarily closes the front end of the`compression-bed while the latter is being filled and during the compression of the filling. It is held in its elevated and normal position by the springs y y and is held down in its closed position by the lever Y', to which it is connected in the manner shown in the drawingsL The lever is held down bythe spring-latch y2 and may be liberated by a pressure of the operators foot against the lower end of the latch, or it can be liberated automatically by connecting a second lever YS, similar to the lever W2, with the latch y2, by means of the cord @/9, in the manner as shown in the drawings, whereby when the striking-plate U on the traveling 'head E"l reaches the lever Y3 it will move the lever enough to throw the latch and liberate the gate-lever Y.

I will now describe the construction and manner of adjustment of the mouthpiece C, mentioned at the beginning of the speciiication.

The bottom of the mouthpiece is a continuation of the bottom of the compression-bed and is changed in width at the same time and in the same manner that the width of the bed is changed. The top is made in adjustable sections, which are supported by the board C. The board C has vertical adjustment in the guides c, whereby the sections will all be simultaneously raised or lowered. The vertical movement of the board will be effected by engagement of the pinions c2 on the stationary shaft C2 with rack-bars C3, projected up from the board.

G4 are angle-bars, between which and the board C the vertical bars Z4 are placed. The bars Z4 have the lateral plates Z1@ riveted to them to increase the bearing-surface against the board and keep the bars from twisting. The bars Z4 are connected with each other in two series (one on each side of the center of the machine) by the lazy-tongs levers ZT, and these levers are connected with the board at one end of each series, whereby the bars Zl will maintain an equidistant relation to each other. The lower ends of the bars are continued and are bent out forward of the machine and provide the supports for the plates C5, which have one of their edges riveted to the bars,while the other opposite edges are underlapped in the manner as is clearly shown in the drawings. The center board C6 is fastened to the board C. The outside plates of both top and bottom of the mouthpiece are extended and -bent to form telescoping closures for the sides of the mouthpiece.

Bars

IOO

IIO

C7 are bolted to the. side boards of the compression-bed and extend forward alongside the mouthpiece C and between the bar on each side, and to the end of the mouthpiece a bar CS is inserted. The upper ends of the bars CE (there are two of them, one for each side of the mouthpiece) are fastened to the outside bar Z4 and are the means whereby the top of the mouthpiece is made to adjust itself in width toconform to the width of the bottom when the latter is changed. A graduated scale enables the board C to be set at any predetermined height, and a set-screw provides means for holding it where it is set.

Having thus fully described my invention, 'what I claim as new, and wish to secure by Letters Patent of the United States, is-
