ALFRED FRESOHL, OF CHICAGO, ILLINOIS.

APPARATUS FOR MANUFACTURING UPHOLS'IERY.

Specification of Letters Patent.

Patented April '7, 1908.

Application filed. December 20, 1906. Serial No. 348,778.

To all whom it may concern:

Be it known that I, ALFRED FREsCnL, a citizen of the United States, residing at'Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Apparatus for Manufacturing Upholstery, of which the following 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 manufacturingpads resembling those shown in the United States Letters Patent to the same patentee, No. 823,785, dated June 19, 1906. In the structure 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, said 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 work structure. The apparatus shown in said Patent No. 824,868 can be used for putting on pads the strips more particularly shown in Patent No. 823,785.

The object of the present invention is to provide an apparatus adapted for the application of a locking strip of ratan or other material through which metallic tacks or the like can be driven, and the invention consists in the construction herein after described and claimed, the invention not being confined in its practical embodiment to the forms of the parts shown.

' In the accompanying drawings-Figure 1 is a cross section of the table showing the strip holders and parts for operating them, it being also illustrated how the coverings of the pad and the strip are secured together; Fig. 2 is a similar view showing the strip holders retracted from the position seen in Fig. 1 and the pad removed; Fig. 3 is an edge view of the table showing the strip holder, the parts being broken out at the middle; Fig. 4 is a sectional view through an edge of the upholstered work illustrating how a pad provided with the strip herein shown is secured to the spring work structure and the frame; Fig. 5 is a sectional detail of a modified form of strip holder; Fig. 6 is a detail in side view on a larger scale showing the eccentric device for moving the strip holders inward and out ward. v

In the views 1 designates the table top which. is usually a one-part rectangular structure and adapted to support the pad to be treated. The table is supported upon ordinary legs 1", fractions only of which are shown, adapted to support the table at the prop er height.

The strip holders 2 and 2 are bars of metal backed or bolstered by solid blocks of wood, said bars being provided with grooves 3 and 3 of a form in cross section conforming substantially to the form of the strip to be placed and supported therein while the edges of the pad coverings are being tacked thereto. In the instance shown the groove is semicircular or half round in cross section and adapted.

to receive a longitudinally divided strip of ratan. 4 designates such a strip of ratan. The holders can be provided with latches 5 to retain the strips in place while the coverings are being applied. Or lips 4 can be formed on the holders to retain the strips in place, as shown in Fig. 5. With this last construction the strip is slid longitudinally into the holder before the application of the pad coverings and longitudinally out of the hold ers after attachment thereto. The strip holders are shown as secured under 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 the edge of the table during the operation of tacking on the coverings, and to be withdrawn from their extreme projected position for the purpose of relieving the strain between the parts, thereby permitting the pad and strip to be more easily removed.

For the purpose of facilitating the operation of moving the bars both outward and inward they are provided with stems or shanks 6 supported to slide in bearings 7 secured to the under side of the table top, said shanks being connected by means of links 9 to a disk 8 having a handle 8*. The disk 8 is mounted on a pin 10 projecting from a bracket 10 secured to the under side of the table near its middle. By turning the disk in the proper direction the holders can be moved inward or outward; and to lock them in their outer position or inner position the edge of the bracket 10 is furnished with notches 10 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 the pin is attached, the pin being held in looking position by means of a coil spring pushing it toward the edge of I the bracket.

The table can be provided with a holder at one side only in which case means for moving and looking a holder at the opposite side can be omitted.

In practice and briefly stated the operation is this: A strip is first properly placed in the holder and the holder slightly projected as seen in Fig. 1. The pad is laid on the table and the tufts of the edges of the pad are pro erly filled and the edges of the coverings pul ed down over the strip and tacked thereto. Tacks or fastening devices of any suitable kind can be used. Because the points of the tacks when driven through the strip strike the iron bar they are bent and securely clenched in place. The usual band, plain or ruffled, can be included in the tacking, as seen at the right hand side of Fig. 1, and afterwards turned down, as seen at the left hand side of Fig. 1, and tacked as shown in Fig. 4.

In Fig. 4 I have indicated how the pad provided with the ratan stiffening strip is secured to the spring work and frame. When properly put in place the stiffening strip eX- tends along and substantially parallel to the edge wire of the spring work and the pad with the strip fits on the spring work somewhat like a lid fits on its boX, and after the flexible band and the projecting ortion of the flexible undercovering or bur ap of the pad are tacked down in place on the frame the ad is held securely in lace on the spring worli by the stifiening or ocking strip after the manner shown and described in the aforesaid patent of E. M. Hulse No. 823,785.

What I claim and desire to secure by Let ters Patent is:

1. In apparatus for the manufacture of upholstery, the combination of a support for the upholstery pad, and a holder at the edge of said support constructed to receive a strip of stiffening material to be added to the pad and through which strip tacks can be driven, said holder being adapted to clench the tacks when driven against 1t through the strip.

2. In apparatus for the manufacture of up holstery, the combination of a support for the upholstery pad, a holder to receive a strip to be added to the pad, and means movable with reference to the holder for temporarily retaining the strip in position in the holder.
