Fearing, South Weymouth, Mass., as signor to United-Carr Fastener Corporation, Cambridge, Mass., a corporation of Massachu setts Application October 24, 1936, Serial No. 107,412 1 Claim. (Cl. 24-?73) My invention aims to provide any improved clip for use in holding one or more wires, con duits, pipes and like members in position on a support. In the drawing which illustrates preferred em bodiments of my invention: Figure 1 is a plan view of a portion of an installation including one of my improved clip members; 10 Fig. 2 is a section taken on the line 2-?2 of ?Figure 1; , - Fig. 3 is a section taken on the line 3?3 of Figure 1; Fig. 4 is an edge view of the installation shown 15 in Figure 1 from the right-hand side thereof; Fig. 5 is a bottom plan view of the installa tion shown in Figure 1; Fig. 6 is a section taken on the line 6-?6 of Fig. 3; Fig. '7 is a perspective view of the clip per se; 20 and Fig. 8 is a side elevation of a second form of improved clip. At the outset I wish to have it understood that 25 I am aware of the fact that clips appearing to be like mine are old. However, I have made certain improvements which may appear slight but which in practice have proved to increase the commercial use and value of such clips. 30 My improved clip shown in Figs. 1 through 'I is preferably formed from a spring material such as brass or high carbon steel and has a generally U-shaped body provided with legs I and 2. The leg I has an outwardly bowed portion 3 to ?t 35 over and hold in place a wire, pipe or the like as shown in Fig. 3. The leg 2 has its free end bent outwardly to provide a guide portion 4. in shape and are formed by simply shearing or slitting the metal and then bending up the sharp pointed portions, as shown in Figs. 3 and 7. My improved clip is shown in connection with holding a wire 6 (Fig. 1) to a relatively thin sup-v port ?I by slipping the bowed portion 3 over the wire and then pushing the clip over the edge of the support as shown in Fig. 3. The guide portion 4 helps to guide the clip over the sup port by providing a cam surface and the ends l0 of the prongs 5?5 ?dig? into the support to prevent the clip from jarring loose from the sup port as friction alone will not work satisfactorily when a clip is used on a moving support. My other form of clip, shown in Fig. 8, is the 15 same as that shown in Figs. 1 through 7, except that the legs I and 2 converge toward their free ends, thus increasing the grip of the prongs against the support. My improved clips are simple in construction, ef?cient in operation, easy to apply and they are being sold in large quantities having taken the place of other clips which do not have my im proved vguide means, gripping formation and . 25' prongs. While I have illustrated and described pre ferred embodiments of my invention 1 do not wish to be limited thereby, because the scope of . my invention is best de?ned by the following claim. ? I claim: . A clip of the class described comprising a strip of metal bent into a generally U-shaped body, wire, tube, rod and the like positioning means provided as a part of said clip, the end of one ' leg of. said U-shaped body portion being bent away from the other leg to provide a guide means assisting in engaging said clip with a rigid sup Adjacent to the point where the guide portion 4 joins the leg 2, I have provided a pair of prongs port and sharp pointed prongs cut from the ma terial of said leg with the bent away end and 40 5?5 which are preferably formed from the mate-. rial of the device. These prongs 5-5 may be lo - said prongs being located inwardly from the end cated at any suitable place where they will engage of the bent portion and having their free ends a support, but I have found that they can best about in a plane with that portion of the-inner be located adjacent to the\opposite edges of the 45 leg?2, as shown in Figs. 2 and 6. Furthermore, I have found that the best prongs are triangular surface of said leg where the curved portion joins the leg. ' " ALLEN C. FEARING.
