BERTON IVI. MATELAS, OF MINNEAPOLIS, MINNESOTA.

ROD-SPLICING CLAMP.

Application filed May 24-, 1916.

To all whom t may concern.'

it known that I, BnnToN M. Marinas, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Rod- Splicing Clamps, of which the following is a specification.

One object of my invention is to provide means for splicing rods or wire rope together in such a manner as to have the full strength of the splice available wit-hout motion.

Another object of my invention is to provide parts on the clamp engaging together, so that the stress in one saddle member is imparted to the other member, independent of the clamping bolts.

Another object of my invention is to provide yielding studs which act as a wedge or incline, keeping the lugs in positive contact.

Another object of my invention is to pro vide an intermediate grip to transfer the stress in one of the saddles directly, and undiminished to the other saddle.

Another obj ect of my invention is to provide corrugations encircling the clamping members to increase the gripping and holding means.

With these and incidental objects in view the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms apart of this specification.

In the drawings Figure 1 is a side view of a clamp embodying my invention, and Fig. 2 is a side elevation of the same.

Fig. 3 is an end view of a modification of the clamp, and Fig. at is a side elevation of the same.

Fig. 5 is an end view of my preferred style of clamp, and Fig. 6 is a side elevation'of the same.

Fig. 7 is an end view of a still further modification of the clamp, and Fig. 8 is a side elevation of the same.

In my preferred construction, as shown in Figs. 5 and 6, 1 and 2 are saddles having lugs 3 and 4;, respectively, to engage with the spaces between corresponding lugs 5 and 6, respectively, on the intermediate grip.

Studs 7 and 8, securely mounted in the saddles 1 and 2, respectively, are adapted to Specification of Letters Patent.

engage with the wed and 10, carried by the saddles 1 and 2, respectively, so as to maintain these wedges in intimate contact at the point 11.

The saddles are preferably constructed so as to be drawn together by i5 bolts 12 and 13, although it is obvious that they may be drawn together by ordinary bolts.

A modification of this device is shown in Figs. 1 and 2, in which the wedges 9 and 10 and the corresponding yielding studs T and S are omitted.

In Figs. 3 and I is shown a modification, in which the wedges 9 and 10 are utilized with the yielding studs '.7 and 3, but the lugs shown in the other two modifications are omitted.

In the clamp shown in Figs. 'l' and 8. a simple and cheaper construction is devised, and two simple clamps 13 and 14e have side projections 15 and 16, respectively, so that the U bolts holding the two together will. bind the two individual clamps together and make them serve as a single clamp.

In the modification shown in Figs. 4 and 8, the rods 17 and 13 are clamped directly together, while in the modification shown in Figs. 2 and (i, intermediate clamps are used to provide a larger gripping surface.

In any of the devices it is evident that the clamping sin-faces ,of the saddles and the intermediate grip may be corrugated, as shown at the point 19 in Figs. 2 and 4.

While I have described my invention and illustrated it in several designs, I do not wish it understood that I limit myself to these constructions, as it is evident that the application of my invention may be varied in many ways within the scope ofthe following claims.

Claims:

1. In rod splicing clamps the combination of a clamping member, wedge shaped lugs on said clamping members and yielding studs mounted in said clamping members.

2. In rod splicing clamps the combination of two saddles, lugs with intermediate depressions on each of said saddles, an intermediate grip having lugs and intermediate depressions on either side thereof adapted to engage with said saddles, yielding studs mounted in said saddles, engaging lugs on each ,of said saddles having one surface thereof perpendicular to the axis of said saddles, and the Opposite surface thereofl at an'angle to said perpendieular surface, said Surface at an angle in each of said saddles being adapted to be engaged 1with said yielding studs in the other of said saddles.

3. In rod Splicing clamps the Combination of a clamping member7 Wedge shaped lugs on said clamping member and yielding studs mounted in said clamping member,

and means associated With said clamping 10.Y
