Application May 12, 1949, Serial No. 92,899 2.- Claims. .(CI. 26 62) My invention relates generally to tenter clips i4 is pivoted to the arms 12. The clamp [4 has and specifically to tenter clips having both a clamp and pins for holding fabrics.

It is among the objects of my invention to provide a tenter clip that will operate properly in a tenterframe with either woven or knitted frabrics.

It is yet a further object of my invention to provide a tenter clip which will positively hold either knitted or woven fabrics, so that they may be stretched to the proper size.

It is another object of my invention to eliminate costly changeover of tentering machines from the pin type to the clip type, or vice versa.

Still another object of my invention is to permit rapid and precise transport of fabrics of all kinds and varieties through a tentering machine, whereby they may be precisely sized.

Still a further object of my invention is to provide a tenter clip that will make all tentering machines universal in their application to fabrics, without the substitution of specially constructed clips usually attendant upon the operation with each differing type of fabric.

And still another object of my invention is to provide an accessory tenter clip of the pin type that may be attached to a clamp type tenter clip;

Among the other objects of my invention is to provide a tenter clip that is simple in form, relatively inexpensive, durable and easy to use and attach.

These objects and advantages, as well as many other objects and advantages, may be attained from the device illustrated in the drawings, in which:

Figure 1 is a vertical side elevation of a tenter clip showing my invention;

Figure 2 is a top plan view of my tenter clip; Figure 3 is a top plan view of my tenter clips pin rack;

Figure 4 is a side elevational view showing a modified form of pin rack attached to a plate of a tenter clip; and

Figure 5 is a bottom view of the modified form of pin rack attached to the plate of the tenter clip.

Referring now to the drawings in detail, my

combined clamp-and-pin tenter-clip presents a body member H. The body member has a pair of arms 12 extending upward over a plate l3 which is attached to the body member II. The plate 13 may be formed integral with the body member I I, or separate and attached by welding, soldering, or other suitable means. A clamp ward the body member I l In operation, my combination clamp-and-pin tenter-clip is arranged in the tentering frame on the conventional endless conveyor track that moves through a heated chamber opposite a similar conveyor track My clip is, at all times, ready to receive a fabric, regardless of its character.

There is no need to dismantle the conveyor to substitute a clamp-type tenter-clip for a pin-type tenter-c1ip,-an operation that may mean hours of idle machinery. 'Nor is the, reverse changeover necessary. Nor is the extravagant expedient of having two tentering machines, one for each type of fabric, necessary. The clamp is always available to be used with woven materials. The pin clip is always available for use with knitted materials. The point of introduction of the fabric is merely changed from the level of the plate M to the level of the pins l9.

Figures 1, 2, and 3 show a rack it which may be attached to the body member II. This rack I8 may also be formed unitary with the arms l2 merely by extending them.

Another way to form a rack is to provide a rack 20 which may be attached by hinges 2| to the plate 22, as shown in Figures 4 and 5. Like the plate I3, the plate 22 may be formed integral with the body member II or separate and attached by welding, soldering, or other suitable means. This rack 20 would normally be disposed in the position shown in Figure 4 with the pins 23 disposed in a downward direction. When it is desired to engage a fabric with the pins 23 rather than a clamp bearing on the plate 22, the rack is pivoted upward in the direction of the arrows shown in figure 4 to the position indicated by dotted lines. Then the supports 24 are advanced in the guides 25 and the rack 20 is thereby brought into play.

At the bottom of the body member H, and on both sides thereof, extended portions 26 are formed with holes 21 formed therein. By means of these holes, the tenter clip is attached to the endless conveyor track of the tentering machine.

The clamp l4 The arms I2, have attached.

It may be seen that changes such as these, as well as many other changes, may be made in the construction, selection, and arrangement of the various parts, all Within the scope of the present claims, without departing from the spirit of my invention.

I claim:

1. A tenter-clip comprising a body member, a fabric supporting plate attached thereto, a clamp pivotally attached to the body member above the plate and gravitationally bearing thereon, a rack positioned on the body member above and parallel to the plane of the plate, and a plurality of pins extending upwardly from the rack.

2. A tenter-elip comprising a body member, a fabric supporting plate attached to the lower part thereof, a clamp pivotally attached to the upper part of the body member and cooperatively en-- gageable with the plate, a support attached to m 4 the upper part 01 the body member, a rack positioned thereon and extending parallel to the plane of the plate, and a plurality of pins extending upwardly from the rack.
