To all whom-it mag concern: V v

Beuit known that I, Grouse N. ABBEY, a

citizen of the United States, residing at Boulder, county of Boulder, and State of Colorado, have invented, certain. new :and useful Improvements in Upholstering 1 achines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersfslrilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and. to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in machines for upholstering.

In the manufacture of cushions for furniture-and bed mattresses, considerable difficulty is usually experienced in introducing the-stuffing material into the. casings. This especially true where spring assemblies are used'as in overstuffed cushions.

It is the object of this invention to; producea machine that is adapted-tombs employed in the manufacture of cushions and mattressesof any size and of the overstuffed or the other kind, and which will greatly facilitate the manufacture.

My invention can be most clearly described and will be most readily understood when reference is had to the accompanying drawings in which the preferred embodiment thereof is shown, and in which Fig. 1 is a top plan view of my machine with parts thereof broken away to better disclose the construction;

Fig. 2 is a side elevation of the machine shown in F ig. l, a portion thereof being broken away;

Fig. 3 is a section taken on line 33, Fig. 1;

Fig. 4 is a perspective view of my machine at one period in its operation;

Fig. 5 is a section taken on line 5 5, Fig. 4, a portion of the casing being shown in place thereon;

Fig. 6 is a detail of the end member; and

Fig. 7 is a section taken on line 7-7, Fig. 4.

My machine comprises a frame having end pieces 1 and 2, top members 3 and 4 and bottom members 5, which form a rectangular structure to which the supporting members 6 and 7 are secured. Members 6 and 7 are substantially identical, each having a bot overlap in, the: manner clearly -in'dicated in Figs. 1 and3. Member "7 is aldjuStablewith respect to member 6 and its,.p osition is determined by two doubled pitch screws and 12 .whoseends are .journaled in theend pieces 1 and 2 and-are rotated by cranks-.13 and 14respectively. fiecured to. thev'ertical sideS of the member 7 ,il'l ehlllltS 15 and-.16 which. cooperate. respectively 1 with the screws 11 and 12. I It is now apparent thatll the' operator, bymeans of the cranks 13 and .14, can rotate the screws 11 and, 12 andthereby move member '7 withrespect to Emember', 6. Since the screws 11 and12 are connected to the member 7 at spaced distances-ibis evident that by unequal rotation of the screws, the member 7 can be tilted with respect, to the member 6 so asjtobe f parallel therewith or inclined with respect-thereto.- Slidajbly mounted in gui'desll' carried bythe transverse frame members 3 and 4 are racks 18 which are operatively related to the pinions 19 that are secured to the shaft 20. A crank 21 is secured to the shaft and serves as the means by which it may be rotated for the purpose of reciprocating the racks. Secured to the forward ends of the racks is a sheet metal plunger head 22 whose cross-section is somewhat channehshaped and which extends transversely of the racks. An adjustable extension member 23 is connected to the member 22 by means which permits the two to be relatively adjusted. By rotating the shaft 20 and pinions 19, the plunger head comprising the members and 23 may be reciprocated. An end member 24 of channel-shaped cross-section has secured near one end thereof a pin 25 which is adapted to engage in an opening 26 in the side 8 of memher 6. Secured to the other end of member 24 is an attachingmeans 27 comprising a spring 28.

Let us now assume that the machine is adjusted so that the parts assume the relations shown in 1 and that it is desired to make an overstuffed cushion whose size is substantially equal to the space between the sides 8, the end 24 and the plunger Ill) members 22 and 23. A layer of cotton batting 29 (Fig. 7 is first laid on the supporting members and upon this layer 30 of hair. A spring assembly 31 is then placed upon the layer of hair and on top of this I place a layer 32 of hair and a layer 33 of cotton. The space between the spring assembly and the sides, end and plunger is now stuflied with cotton or hair, as indicated by numerals 34. The plates 35 and 36 are then put in place with their outer edges underneath the inturned flanges 9 in the manner shown in Figs. 4 and 7. Pressure may now be exerted on the upper surface of plates 35 and 36 so as to compress the material underneath. For the purpose of holding the material compressed while the casing 37 is put into place, I provide a holding means consisting of a bar 38 which is held in adjusted position by means of a clamp 39. With the parts in the position shown in Figs. 4 and 7 the end piece 24 is removed and by means of the screws 11 and 12 the sides 8 are moved together to the extent required to permit the casing 37 to be drawn over the end of the machine to the position shown in Fig. 5. After the casing has been put into place, the screws 11 and 12 are operated to move the sides 8 apart until the casing is stretched to some extent.

The operator now grasps the crank 21 and rotates the same in such a direction that the plunger moves outwardly, whereby the insides and the casing will be moved outwardly in a manner clearly apparent from the drawings. When the cushion has been shoved entirely of? from the machine by the plunger, the plates 35 and 36 are withdrawn from the cushion and the open side sewed up, which completes the same.

If the stufiing of the cushion or mattress is formed exclusively of hair or cotton, the material can be formed by superimposed layers which give better results than if the material were stuffed into the cushion in the usual manner.

It is obvious that the machine can be made as large or as small as desired and may therefore be used for making small cushions or large bed mattresses.

Having now described my invention, what I claim as new is:

In an upholstering machine, in combination, a frame, a supporting member comprising two parts, each of which has a bottom portion and a side portion, the bottom portions being overlapping, the side portions having their upper edges bent towards each other so as to form overhanging flanges, one of said parts having one end secured to said frame, means for moving said parts.

towards and away from each other, a plunger slidably connected to said frame, means for reciprocating said plunger, and a top for said supporting member, said top consisting of two separate plates adapted to overlap each other, one edge of each of said plates being adapted to project under said overhanging flanges.

In testimony whereof I afliX my signature.

GEORGE N. ABBEY.
