' CHAIN SLIDE Eugene Morehouse, Providence, R. I., assignor to B. A. Ballou & Co. Incorporated, a corporation of Rhode Island Application May 7, 1949, Serial No. 91,905

1 Claim. (CI. 24-81) This invention relates to a chain slide, sometimes referred to as a lariat chain slide and which is adapted to vary the size of a loop of flexible material which extends about the neck of the person.

One of the objects of this invention is to provide a slide which may be moved to vary the size of the loop of the flexible cord or chain about the neck and yet permit the easy insertion or removal of the chain or flexible cord from the slide.

Another object of the invention is to provide an arrangement whereby the two lengths of flexible material may be held securely in the position to which the chain is adjusted.

Another object of the invention is to provide a slide of a minimum number of parts for assemy.

Another object of the invention is to provide a slide without soldering for assembly thereof.

Another object of the invention is to provide an arrangement so that the two holding parts are intererelated so that there is a balanced action between them in their holding action.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure l is a face view showing a chain positioned about the neck of a person with my slide in place;

Figure 2 is a view similar to Figure l of a fragmental portion on a much larger scale;

Figure 3 is a section on line 3-3 of Figure 2 and on a smaller scale;

Figure 4 is an edge view on line 44 of Figure 2;

Figure 5 is a perspective view of the device;

Figure 6 is a perspective view of a modified construction.

In proceeding with this invention I have provided two parts which are so shaped that each of the parts may be formed by tools in multiple and the two parts thereafter easily assembled by bending a portion of one of them. One of the parts has hooks at each edge, while the other part is elastically resilient and tends to force the chain or cord upwardly against the hooks into binding relation therewith.

With reference to the drawings, there is a body member designated generally in formed from flat sheet stock with its ends cut out and rolled to provide a pair of hook shaped guides II at one end and another pair l2, I2 at the other end, these hooks being rolled inwardly to provide a concave surface I3 with a space M between the ends l5 and the inner surface of thebody plate It. The hooks are in somewhat the form of a circle (Fig. 4) to a point l6 and then the end portions are flared upwardly as at ll to provide an entrance guide lip for insertion of the flexible member or chain into the hook. A space It is provided between each of the hooks I l, l or l2, l2, as is clearly shown in the drawing. Ears I9, I 9 are bent upwardly from the opposite edges of the body It! at the mid-point along the edge and are provided with openings for pivotally mounting the other member of the unit which is designated generally 2 I.

This member 2| is cut out in its center and is somewhat tapered at its ends 22 to a size to freely pass through the space It between each of the hook-shaped guides H, II and |2, |2, while this member 2| is provided with trunnions 23 extending outwardly from its midportion and into the openings 20 in the ears It. The member 2| is of thin sheet stock and flexible so that if both of its end portions are depressed they will tend to swing upwardly and return to a position between the hooks H, II or l2, l2.

In use a flexible member such as portions 25 and 26 of a cord or chain may be laterally slid into the hooks II, II or l2, I2 to be located in the arcuate concave guide portion 21 thereof, as shown in Figure 4, by movement of the ends 22 of the member 2| due to flexing of the member. Thus, the ends of the member 2| tend to force the cord or chain portions 25 and 26 upwardly, as shown in Figure 4, against the under surface of the hooks or guides and in part against the inner edges of the hooks so as to bind the chain or flexible member in adjusted position in the slide. The arcuate under surfaces 2'1 of these hooks H and l2, l2 provide guides so that the chain may be slid through the slide frictioning on this concave surface, the friction being dependent upon the pressure exerted by the member 2| which is such that the slide may be moved along the flexible members so as to adjust the size of the loop 30 thereof which may be passed about the neck.

In the form shown in Figure 6 the body member ID is provided with hooks II, II and l2, l2 identical with the showing and description in the form shown in Figures 1-5 but in Figure 6 I have a different form of resilient pressure means. Here I have an H-shape member 30 with four spring arms 3| extending from a cross bar 32 each offset from the plane of the bar as at 33 and extending toward the concave side of each hook. The bar 32 is notched at its ends and tabs 34 are 3 located in the notch and bent over the bar binding it tightly to the body member to hold it in position.

Each arm 3| will press the chain against the concave surface of the hook for frictioning as the slide is moved along the chain.
