1 '0 all whom it may concern:

Be it known that I, FRED Gnuo, a citizen of the United States, residing at Saranac Lake, in the county of Franklin and State of New York, have invented new and useful Improvements in Cushion-Forms, of which the following is a specification.

This invention relates to forms for the manufacture of cushions and in the form embodied in the drawings the device is particularly designed for use in the manufacture of automobile seat cushions, the object of the invention being to produce a form of the class referred to in which the seat cushion may be built up and the different plies or thicknesses and sections of the leather and fabric properly combined and clamped together at their edges, the form being of sectional construction combined with means for moving the sections toward and away from each other thereby enabling the completed cushion to be readily removed from the form.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the-accompanying drawings Figure 1 is a plan view of the form of this invention;

Fig. 2 is a vertical cross section through the same;

Fig. 3 is a vertical longitudinal section through the same;

Fig. 4 is a detail vertical cross section, showing the form expanding and contracting means;

Fig. 5 is a plan view of the clamping strips;

Fig. 6 is a fragmentary sectional view of the outer strip;

Fig. 7 is a similar view of the inner strip; and

Fig. 8 is a detail section through a marginal portion of a completed cushion.

In the preferred embodiment of the present invention, the form comprises an elongated frame designated generally at A and divided along an approximately central line into two relatively movable sections 1 and 2. One of the sections is shown as provided with rounded corners 3 to give a corresponding shape to the corners of the cushion.

The sections 1 and 2 of the form are movable toward and away from each other by means of adjusting screws at which pass through the section and. are threaded into sockets 5 in the section 1. Each of said screws is provided with a groove 6 and passes through a slot 7 in a plate or metal strip 8 secured to the section 2 adjacent to one corner thereof. By this means each adjusting screw is adapted to be turned in either direction withoutadvancing or moving longitudinally in the section'2, but by reason of the threaded engagement of said screw with the other section l of the form the sections 1 and 2 are moved toward or away from each other in accordance with the direction that the adjusting screws are turned.

9 designates a clamping strip receiving groove which extends continuously around the inner faces of the sections of the form, said groove 9 being adapted to receive both an outer clamping strip 10 and a series of inner clamping strips 11. The outer clamping strip is preferably continuous or endless and consists of a single piece of metal of suitable thickness and width to fit loosely in the groove 9, said strip 10 being provided at intervals with pointed barbs or prongs 12 struck or punched from the metal thereof and. also provided with short rear prongs 13 formed in the same way.

A separate inner strip 11 is provided for each of the four sides of the form and cushion and each of said strips 11 is provided with slots 14; to receive the longer prongs 12 of the outer strip. As shown in Fig. 8. the plies or thicknesses of the cushion covering material are confined between the outer and inner clamping strips, all of the prongs passing through the overlapping portions of the cushion covering plies and the longer prongs passing through the slots 14 and being clenched against the inner face of the inside clamping strip 11. The strips 10 and 11 thus constitute clamping or binding strips for the cushion covering sections.

15 designates a bottom for the form, said bottom preferably consisting of sheet metal and being fastened as shown at 16 to one of the sections of the form while overlapping the other section and being unattached thereto so as to admit of the necessary relative movement between the two sections. On its upper side the bottom 15 is provided with slotted button holders 17, in which buttons may be placed and properly positioned rela tively to the cushion preparatory to placing the top cover of the cushion in place on said bottom 15.

After the cushion has been made up and clamped by the means described the completed cushion may be readily removed from the form by operating the adjusting screws so as to separate the sections of the form. This releases the clamping strips 10 and 11 from the groove 9 whereupon the completed cushion may be lifted out of the form.

It is preferred to provide the form With supporting lugs 18 as shown to raise the main body of the form to the proper elevation for the convenience of the operator.

I claim A form for the manufacture of seat cushions and the like comprising a frame having internally the shape of the marginal edge of the finished cushion, said frame being open at the top and the opposite bars thereof being formed with internal longitudinal intersecting and communicating grooves located between the top and bottom edges thereof and forming seats to contain edge clamping strips for the cushion, said frame being divided between opposite bars thereof into a pair of sections the meeting faces of Which are intersected by said grooves, and means for separably securing said sections together.

In testimony whereof I my signature in presence of tWo Witnesses.

FRED GERO.
