MACHINE MAKING CUSHIONS.

SPECIFICATION forming part o'f Letters Patent No. 702,340, 'dated June 1o, 1902.

Application tied April i9, 1901.

Be it known that LGEQRGE BUoKMAN,a citi-M zen of the United States, `residing at Burlington, in the county ofBurlington and State of New Jersey, have invented certain new and useful Improvements in Machines for Making Cushions,of which the followingis a speciication.

My invention relates to that class of apparatus employed for facilitating the manufac; ture of cushions for carriages and other pur` poses; and my invention consists in certain details of construction fully set forth hereinafter and illustrated in the accompanying drawings, in Which- Figure lis a front view,'in part section, of) my improved apparatus. Fig. 2 is a transverse section on the line 2 2, Fig. l; Fig. 3, an enlarged part-sectional View of the parts used for supporting the coverings and lling and connecting the same. Fig. 4 is an elevation in part section of one of the button-pegs and protectors; Fig. 5, a sectional elevation of one of the button-pegs; Fig. 6, an end view of one of the pegs; Fig. 7, a plan View of the perforated presser-boards.

The frame of the machine is provided with side pieces in the shape of uprights CZ, which may be connected by cross-pieces kl and suitably braced, and to the uprights d are secured two parallel beams c c,which serve as supports for the carriage b of the table e. Preferably the carriage l) does not rest directly on the beams c, but is provided'with rollers m, which run upon rails a in grooves of the beams o, the said rails resting on springs fn.

The table e is pivoted so as to swing centrally upon the carriage b. This pivoting may be done inany suitable way.- f As shown, there is a disk p below the table e with a pin q fitting a recess in the top of the carriage and serving as a pivot for the table, the ends of which may rest on studs r fto prevent the table` from sagging 4down? at the ends.

Each upright CZ is provided With a guide s, extending-into a slot in the end of a presserbeam 7L, to which are connected cords l, passing over guide-pulleys 3 3 and each supporting aweight w, which tends to lift the presserbeam, while screws ff and g extend through lthreaded bearings of the cross-bar k, so that their inner ends may be brought against socket-pieces t t on the pressser-beam to depress tfhe latter.

i order that theblades Ymay properly cooperate with a followerboard of the character referred to below.

The above-described parts may be used in connection with any suitable cushion beds and frames, but preferably in connection with the parts illustrated in Figs. 3 to 7. In these figures there is represented a cushion-bed l1, having sockets for the reception of button- `pegs 12, each of which has a recess 13, adapted to the head ofthe button, different pegs being used for a different button, and the said pegs are made, preferably, of wood with cross-slits y y, giving a certain amount of spring which will tend to clamp the button-head. Upon the cushion-bed ll is placed the cushion-bed frame 4, and the cloth or other material constituting the face of the cushion is placed upon the pegsi with the shanks of the buttons passing through holes in the cloth at proper points, the fullness of the cloth extending between lthe pegs, and the edges of the cloth are plaited against the inside of the frame 4 and are then held down by suitable clamping devices-#as forinstance, by means ofaclamping-Wire 5 around the frame. Upon the bedframe 4 is placed a second frame 6, and the stem of each button is covered by a protector 17 ,pointed in shape and with a socket to receive the stem, as shown in Fig. 4, and the filling is then placed Within the frame 6, and the protectors are then removed and the fabric cover for the bottom is laid on, after which a perforated follower-board Sis placed upon the said material, and Athe beam 7?. is forced down by the screws ff, thus bringing the bladest' to a position to bear upon the board, as indicated in Fig.f7, andsuflicient pressure is applied by means of thescrews and beam to condense the filling to the desired extent. While the iilling is thus under compression the shanks of the buttons are IOO clenched or provided with tufts or otherwise, so as to hold the bottom covering to the Shanks. The presser-beam h is now lifted, and the seat-frame is supplied to the bottom material and is held in place while the edges of the bottom material and the top cover are tacked to the frame, the presser-beam 7L being brought against the seat-frame by means of the single screw g, (which has a more rapid thread than the screws f,) as but comparatively slight pressure is required to hold the seat-frame in place.

It is of course necessary to provide a positive or solid bearing for the carriage when pressure is exerted thereon during the condensation of the filling of the cushion. The journals of the rollers m would not at all times withstand this pressure Without. liability of being bent, and thereby rendering the rollers inoperative. It is also necessary in order that the carriage may be freely moved that it should not bein frictional engagement with the beam c during such movement. To attain these ends, I provide the yielding snpporis for the rails upon which the rollers m run. Normally the carriage is out of engagement with the beams c; but when pressure is applied to it the rail-supports will yield and permit either the carriage or the bearings for the journals of the rollers to directly engage the beams c, and no strain will be imposed upon The journals ofthe rollers in. Further, it is obvious that asthe table is pivoted to the carriage it may be swung around upon the carriage to any desired position required to enable the proper manipulation of the material in making the cushion. To further support the parts when pressure is applied, a central standard i; may be arranged so that the carriage will take its bearing on the upper end of the same when pressure is applied.

While I have shown screws for applying the pressure, it will be evident that any desired forms of presser devices may be substituted therefor, and it will also be evident that there may be different forms of yielding bearings for the table and that the tablecarriage and the frame of the apparatus may be diiferently constructed from the construction shown without departing from the main features of' my invention.

Without limiting myself to the precise construction and arrangement of parts shown, I claim as my inventionl. The combination in a cushion-making machine, of a supporting-frame, pressing devices, and a sliding carriage and yielding bearings therefor, substantially as set forth.

2. The combination with the sliding carriage of a cushion-making machine, of a table supported thereby, rails upon which said carriage runs, and yielding bearings for said rails, substantially as set forth.

3. The combination with the frame of a cushion-making machine, of recessed beams, rails fitted to the recesses in said beams, springs supporting the rails, and a sliding carriage provided with wheels resting upon the rails, substantially as set forth.

4. The combination in a cushion-making machine, of a supporting-frame, pressing devices, a movable carriage, yielding bearings for the carriage, and a fixed bearing o to be engaged by the carriage when the yielding bearings are depressed, substantially as set forth.

5. The combination of the carriage b, yielding supports therefor, a table e pivoted to said carriage, presser devices, and a support u in position to be engaged by the middle portion of the carriage when the latter is depressed, substantially as set forth.

6. The combination of the carriage b and yielding supports therefor, and a table e pivoted to said carriage and presser devices, substantially as set forth.

7. The combination with the frame, the table, and the follower-board, of acushioumaking machine, of a movable presser-beam, and adjustable blades carried by the said beam, substantially as set forth.

8. The combination of the frame, the table, the follower-board, the presser-beam provided With slots and the blades i provided with bolts extending through the slots and with nuts bearing upon the presser-beam, substantially as set forth.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribingwitnesses.

GEORGE BUCKMAN.
