SPECIFICATION forming part of Letters Patent No. 279,385, dated June 12, 1883.

Application filed April 6, 1883. (N 0 model.)

To aZZ whom it may concern:

Be it known that I, JACOB HERKIMER, a, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented-a certain new and useful improved loop-clamp to be used for holding traces or other straps or cords in connection with vehicles or other things to be drawn by horses or other draft-animals or power.

The object of my invention is to furnish a clamp simple in construction, having few parts, and those easily adjusted, and so put together that it is practically impossible for it to get out of order, or to find a person so simple as not to be able to use it without previous instruction.

The accompanying drawings illustrate my invention and form a part of this specification, and the following is a detailed description of it.

It is simply a metallic box or loop of any required'size or length, open at theends, with the bottom extended, and so made as to be easily and firmly attached to aleather or other surface. In each of thesides or walls of thisbox or loop are one or more oblique slots, directly opposite each other, having the same degree of :n obliquity, and in each of these slots is inserted a metallic roller, either smooth or corrugated,

with trunnions on each end, and so arranged as to slide easily on these trunnions from end to end of the slots as the strap or other thing to be held is inserted into what may be termed the rear end of the box or 1001), between 3 5 the rollers and the'bottom, and when. the strap or thing to be secured is in place, any attempt to withdrawit causes the rollers to grip it automatically between them and the bottom of the box or loop, so that no force can withdraw 40 it, and the harder the strain the more firmly is the trace or other thing held; but the mo ment the traction ceases, if it is desired to remove the strap, a slight push of it forward, or elevation of the rollers by a slight pressure of the thumb and finger upon the trunnions, or, rather, upon the heads of the screws that hold the rollers in place, at once releases it.

It will be seen that the principle of my invention may be embodied in mechanism differing in details of construction. I have shown the form which I prefer for most purposes in the drawings, which are hereinafter particularly'described.

The inner or upper surface of the bottom of the box or loop may be corrugatedtransversely or otherwise roughened to give additional grip, and this whether the rollers are smooth or corrugated, and if the side walls and bottom are of sufficient strength, and it is desired, the top of the box or loop may be dispensed with, as it performs no service other than to lend strength to the loop, although the invention may be. made much neater and more ornamental by its being retained.

In the drawings like letters refer to like parts in all the figures, and the lower letters of the alphabet are used to designate things not deemed parts of the invention.

Figure 1 is a perspective of the clamp attached to the side strap of a harness, z 2, as a trace-11o] der. (1 c a are the side walls ofthe box or loop. I) b b are the oblique slots, of which there are two in each wall of the model shown in Fig. 1, one being covered by the metallic plate 0, which plate is placed upon each end of the trunnions outside of the walls of each clamp, having more than one roller to give uniformity to the elevation or depression of the rollers. (l d is the bottom of the box or loop, elongated so as to admit the rivets y :1 that secure the clamp to the strap or other surface on which it is to be used. 0 e are screws that go into the ends of each trunnion and secure the rollers and metallic plate 0 in place, and by the unscrewing of which the rollers can be removed.

Fig. 2 is a sectional view, such as would appear if Fig. 1 were divided from end to end on the dotted line 2 2, and the nearest half of the figure removed, and shows the oblique slots I) b, the rollers ff resting in the slots and upon a strap, a: as, which strap is between the rollers and the bottom (I d of the loop or box.

Fig. 3 is one of the rollers corrugated, showing the trunnions g g and screws 6 e in" the ends of the trunnions. The heads of these screws can be made of any desirable size or shape to suit taste or circumstances.

Fig. 4 is a slightly-enlarged view of the metallie plate a, with holes for the trunnions.

As many rollers as are desired may be put in each clamp, and the length of the rollers (exclusive of the trunnions) is about equal to the width of the box or loop, measuring from wall to wall on the inside, being just enough less to admit of their revolving without friction of the shoulders against the walls, and the length of the trunnions is gaged by the thickness of the walls and the eonneetingplate a, (when one is used.) The screws 6 6 may be omitted and a solid rivet-head made on the ends of the trunnions. This will give greater strength and solidity to the rollers, and is deemed best for ordinary purposes.

JACOB HERKIMER.
