Patented Nov. 14, 1939 UNITED ST'l'ES PATENT OFFCE 4 Claims.

This invention relates to clip construction. Particularly it relates to a novel and improved form of metal clip primarily adapted to interconnect a longitudinally movable bar or arm with a pivotally mounted member in order to effect oscillation of the pivotally mounted member by means of longitudinal movement of the bar or arm.

It is a primary object of the present invention to provide an improved form of clip construction which is extremely simple in structure, cheap to manufacture, and which provides a positive self-locking interconnection between the parts which it serves to connect.

It is a still further object of the present invention to provide a clip construction of the type defined above in which novel means are provided for effecting adjustment of the clip and accurately determining the longitudinal position with respect to the bar or arm on which it is mounted.

It is a still further object of the present invention to provide a clip construction of this generic type which is exceedingly easily mounted in position with respect to the members with which it is associated, and which when so mounted is permanently resiliently retained in position with respect thereto.

Yet another feature of the present invention consists in the provision of a clip construction of the generic type described above in which the clip itself is formed from a single integral sheet metal stamping so constructed and arranged that it serves to provide a positive locking engagement with the parts with which it is associated.

Many other and further objects, advantages, and features of the present invention will become clearly apparent from the following specification when considered in connection with the accompanying drawing forming a part thereof.

In the drawing:

Fig. 1 is a fragmentary side elevational view of a portion of a carburetor of an internal combustion engine illustrating one embodiment of the improved clip of the present invention utilized in connection therewith.

Fig. 2 is an enlarged fragmentary sectional view taken substantially on the line 22 of Fig. 1 illustrating in detail the manner in which the clip is mounted upon the control arm.

Fig. 3 is an enlarged transverse sectional View taken substantially on the line 3-3 of Fig. 1 illustrating in detail the manner in which the clip is mounted with respect to the arm which it serves to actuate.

Fig. 4 is an enlarged perspective view of a clip embodying the improvement of the present invention.

Fig. 5 is an enlarged perspective view similar to Fig. 4 illustrating a modified form of clip construction.

With more particular reference to the drawing, it will be readily understood that the clip shown therein is merely illustrative of one specific embodiment of the invention, and that substantial departures from the specific structure shown may be made which at the same time will fall within the generic scope of the invention as presented and defined in the subjoined claims.

In Fig. 1 a portion of a carburetor is shown comprising an inlet duct or tube 5, which is adapted to be controlled by a conventional butterfiy valve not shown. This butterfly valve is actuated by means of a shaft 6 to which is rigidly secured a crank arm 1. This crank arm I has an aperture 8 in the outer end thereof adapted to receive one portion of the improved clip, and it will be subsequently seen that the clip of the present invention provides relatively simple means for interconnecting this crank arm 1 with a longitudinally movable actuating rod or bar 9.

The clip in the form shown comprises a single integral sheet metal stamping which is preformed in its central portion to provide a substantially tubular projection ID. This projection I0 is preferably preformed to provide upstruck lugs H on each of the opposite sides thereof, which lugs have their tip ends l2 bent inwardly to provide means, as will hereinafter be more clearly seen, for securing the clip as a whole in position within the aperture 8 of the arm I. Formed as an integral part of this generally cylindrical central portion are a pair of wings l3 and M, which wings are bent sharp-1y away from the central portion of the clip, and are disposed in divergent relation with respect to each other.

It will be readily apparent that when the tubular central portion In of the clip is inserted within the aperture 8 of the crank arm I, the upstruck tange ll will be compressed permitting the insertion of the clip until the wing portions seat against the face of the arm 1. It will be seen that when the clip has been thus inserted the upstruck lugs II will spring outwardly permitting the tip ends thereof to seat against the opposite face of the crank arm 1 adjacent the aperture 8 thereof, thus firmly locking the central body portion of the clip in position in the aperture of the crank arm. It will be readily apparent that due to the generally cylindrical configuration of the central portion of the clip as a whole, this interlocking engagement of the clip and crank arm will at the same time permit relative rotational movement of the body portion of the clip within the aperture, but will retain the clip firmly seated in place therein.

The wing portions l3 and I4 have apertures l5 and [6, respectively, formed therein which apertures are adapted to receive the actuating rod 9. Inasmuch as these wing portions are inclined to each other, it has been found desirable to facilitate mounting of the clip to make the apertures I5 and I 6 slightly larger than the exterior diameter of the rod Q in order to permit the insertion of the rod and at the same time, permit these wing portions to be maintained in inclined relation with respect to each other. A portion of the metal from the aperture 15 of the wing portion 13 is struck outwardly to provide a projecting lug I! having a hook-like end l8 which, as will hereinafter be seen, is adapted to engage the extreme end of the operating shaft in order to positively position the clip with respect thereto.

After the clip has been completely formed it is heat treated and tempered in order that it will be extremely resilient, and so that the metal thereof will be substantially harder than the metal with which the clip is associated. The wing portions 13 and M are tempered so that they have an inherent tendency to assume a position whereby the angle of inclination of one to the other is substantially greater than that which the parts must assume when the rod 9 is inserted through the apertures l5 and it. This construction provides a clip which firmly grips the rod and the hard metal of the clip has a tendency to dig into the surface of the rod thus firmly positioning the clip with respect to the rod on which it is mounted. In the specific form of the invention shown in Figs. 1 to 4 inclusive, of the drawing, it will be readily understood that the hook-like member It also serves to retain the clip in predetermined longitudinal position with respect to the rod on which it is mounted.

In the modified form of the invention illustrated in Fig. 5 of the drawing, it will be seen that the central portion of the structure is substantially the same as has been described above, and the same reference characters are used therefor. In this form of the invention the central body portion is provided with a pair of Wings 28 and 2| which have apertures 22 and 23 respectively therein, the marginal edges of which apertures are adapted to engage the rod 9 in substantially the manner described above, and firmly grip the same. It will be readily appreciated that in this form of the invention the clip may be adjusted to any desired position, longitudinally with respect to the rod, and this adjustment may be easily and simply accomplished by merely squeezing the wing portions toward each other in order to release the grip of the portion upon the rod. The clip may then be slid to the desired position and when the wing portions 2E] and 2! are releasedthey will serve to firmly grip the exterior surface of the rod and retain the clip in predetermined adjusted longitudinal position with respect to the rod on which it is mounted.

It will be readily appreciated that in the form of the invention illustrated in the drawing and described above the clip provides a structure which permits pivotal movement of the clip within the aperture 8 in the crank arm I in order that as reciprocatory movement of the rod 9 takes place the crank will be moved arcuately in order to adjust the position of the control valve in the duct 5. It will likewise be appreciated that due to the fact that the clip is made of extremely hard and highly tempered steel, the clip will grip the rod 9 firmly and be retained in predetermined longitudinal position thereon.

While but two illustrative embodiments of the present invention have been illustrated and described, many other and further modifications thereof falling within the scope of the invention as defined in the subjoined claims will become clearly apparent to those skilled in the art.
