APPARATUS FOR MANUFACTURING UPHOLSTERY.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed December 12, 1906. Serial No. 347,424.

To all whom it may concern:

Be it known that I, GEORGE M. FINCKEL, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in A paratus for Manufacturing Upholstery, ofpwhich the following, in connection with the accompanying drawings, is a specification.

The invention relates more particularly to the kind of apparatus illustrated in the United States patent of Edwin M. Hulse No. 824,868, dated July 3, 1906, for manufactun ing pads resembling those shown in the United States Letters Patent of the same atentee, No. 823,785, dated June 19, 1906. n the vstructure of said Patent No. 824,868 the edge of the table for supporting an upholstered pad is shown as provided With grooves for the reception of a series of fastening devices to be projected through the fabric by pressing the fabric down on them, and in the structure of said Patent No. 823,785 the pad is described as provided with a locking strip at each of its edges for the purpose of securing the pad on the top of a spring workstructure. The apparatus shown in said Patent No. 824,868 can be used for putting .stiffenino' or locking stri s on pads as more particu arly shown and) described in Patent No. 823,785.

The object of the present invention is to provide an im roved apparatus adapted for use in the ap ication of a stilfening or locking strip pre' erably of metal and preferably provided with perforations through which tacks can be driven or projected and clenched to secure the stiffening or locking strip to the covering of the pad and the invention embodies chiefly, among other things, improved means for holding such strips and adapted for clenching the tacks or fastening devices, but my invention is not confined in its practical embodiment to the instance of it herein shown and described.

In the accompanying drawings-Figure 1 is a cross section of the table showing the strip holders and parts for operating them 5 Fig. 2 is a similar view showing the strip holders retracted from the yposition seen in Fig. 1 and the pad removed; Fig. 3 is an edge view of the tablel showing the strip holder, the parts being broken out at the middle Fin'. 4 is a fractional plan view of the strip holder and the rods attached for moving 1t laterally inward or outward; Fig. 5 is a scctional detail of the strip holder on a larger scale; Fig. 6 is a fraction of a perforated stiffening or locking strip Fig. 7 is a detail in side view on a larger scale of the eccentric device for moving the strip holder; and Fig. 8 is a sectional view through an edge of the upholstered work illustrating how the pad provided with the strip herein shown is secured to the spring work structure and its frame.

In the views 1 designates the table top or pad support which is usually a one-part rectangular structure and adapted to support the pad to beV treated. The table is su ported upon ordinary legs 1 a, fractions on y of which are shown, adapted to sustain the table top at the proper height from the oor.

In the instance shown the strip holder comprises principally two parts, towit: first, an outer bar 2 generally of U-form in cross section but provided with inwardly turned lips 2a between which is an intervening space to permit the application of the fastening devices, and second, what may be termed an inner clenching and strip-clamping bar 3. In the instance shown the clenching and clamping bar 3 is located within the outer bar 2 and is adapted to be moved toward and from the lips 2a. Means for pressing and holding the clenching and clamping bar toward the lips 2a may consist of several set screws 4 threaded through the inner wall of the outer bar 2 and engaging the inner side of the inner bar 3.

The character 5, see Figs. 5 and 6, designates the stiffening strip that can be used. This is conveniently of iron cr steel and perforated as seen at 5a, Eig. 6. When the screws have been turned inward to provide ample space for the purpose, the strip 5 is inserted through-the open end of the bar 2 between the lips 2EL and the bar 3. The bar 3 can then, by turning the screws 4, be moved outward to clamp the strip 5 between the 100 bar 3 and the lips 2a. The bar 3 as shown has a concaved curved surface 3a along its outer face to provide for turning and clenching the points of the tacks driven through the strip 5. is especially advantageous when the strip 5 is of hard metal, for if the bar lies iiat against the strip the points of the tacks might be merely crushed and not turned and clenched.

The tacks, if made of sufficient length, .are 110 This concaved clenching surface by sliding it endwise thereinto.

turned by the concave surface beyond the edge of the hole in the strip and engage the inner side of the strip and thus secure the strip to the fabric of the pad. The strip holders as thus described are preferably secured to the opposite edges of the table top and parallel thereto, and they are preferably adapted to be slid horizontally laterally to project a little beyond said edge during the operation of tacking the pad covj erings and strip together, and to be moved from their projected position for the purpose of relieving the strain between the parts, thereby permitting the pad and strip to be more easily taken off the table.

For the purpose of facilitatingthe operation of moving the bars jointly both outward and inward they are provided with stems or shanks 6 supported to slide in bearings 7 secured-to the underside of the table top, said shanks being first connected together by rods 6au and further connected by means of links 9 to a disk 8 having a handle 8a. The disk 8 is mounted on a pin 10b projecting from a bracket 10 secured to the under side of the table near its middle. disk in the proper direction the holders can be moved outward or inward: and to lock them in their outer or inner position the edge of the bracket 1 is made with notches 10a to be engaged by a spring-actuated pin 11 on the handle of the disk. The pin 11 can be operated by means of a handle 12 to which said pin is attached, the pin being held in locking position by means of a coil spring pushing it toward the edge of the bracket and into one or the other of the notches.

The table can be provided with a stripholding device at one side only, in which case means for moving and locking a holder at the o posite side can, of course, be omitted, and t e pad held at the edge not being treated in any suitable way.

In practice, and briefly stated, the operation is this: A strip 5, such as is shown in Fig. 6, is first properly placed in the holder The clamping-bar 3 is then moved outward by means of the screws 4, whereby the strip 5 is clamped between the bar 3 and the lips 2a, 2a, on the bar 2. The strip-holder, including the parts 2 and 3, is then slightly projected beyond the edge of the table top, see Fig. 1. The pad is then laid and secured on the table with its edge parallel to the holder. The

, edge tufts of the pad are then properly filled and the flexible coverings tacked to the strip 5 as fast-as the tufts are satisfactorily lled. The opposite edge of the pad is treated in the same way. After both edges have been treated the holders are drawn inward by operating the lever 8a. Tacks or fastening devices of any suitable kind can beused, and the form of the concave clenching surface on the bar 3 varied to suit them. The usual By turning the j 1 edge band, plain or ruffled, can be included in the tacking, it being first attached asfseen at the right-hand side of Fig. 1, and afterl wards turned down to cover the heads of the j tacks, as seen at the left-hand side of Fig. 1.

l lnFig. 8 l have indicated how the pad prol vided with the stiffening .strip 5 can be sei cured to the spring work and frame of a i couch. When properly put in place the stiffening strip extends along and substantially parallel to the edge wire of the spring work and the pad with the strip ts on the spring work somewhat like a lid fits on its boX, and after the flexible band and the proj ecting portion of the fieXible undercovering or burlap of the pad are tacked down in place on the frame the pad is held securely in place on the spring work by the stiifening or locking strip after the manner shown and described in the aforesaid patent of E. M.
