WILLIAM T. BUCK, OF VLIETS, KANSAS.

CABLE-SUPPORTING PULLEY-BRACKET.

Specification of Letters Patent.

Application filed February 23, 1910.

Patented Dec. 6, 1910. Serial No. 545,388.

To all whom it may concern:

Be it known that I, WILLIAM T. BUCK, a citizen of the United States, residing at Vliets, in the county of Marshall and State of Kansas, have invented a new and useful Improvement in Cable-Supporting Pulley- Brackets, of which the following is a specification.

This invention relates to certain new and useful improvements in cable supporting brackets, the object being to provide a pulley bracket which will support the operating cable in such a manner that all danger of the same jumping out of the bracket is prevented and at the same time the connecting arm of the mail carrier is allowed to pass through the same without any danger of it becoming caught.

Another object of my invention is to provide a pulley bracket which is exceedingly simple and cheap in construction and one in which the parts are carried by a cross bar, adapted to be secured to supporting posts whereby the lea dways of the operating cable will be held at equal distance apart in all places.

A still further object of the invention is to provide a pulley bracket with guide members so mounted in respect to the bracket that the endless cable will lead back on to the pulley if the same should be accidentally displaced.

Another object of my invention is to provide a pulley bracket with depending diverging guide fingers which are so arranged over the pulley that the cable will be prevented from jumping to a certain extent and at the same time the arm connecting the carrier to the operating cable will be guided through the bracket in such a manner that all danger of the arm becoming caught in the same is prevented.

With these objects in view, the invention consists in the novel features of construc tion, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.

In the drawing forming a part of this specification:Figure 1 is an end elevation of an intermediate post showing my improved pulley bracket secured in position thereon. Fig. 2 is an enlarged side elevation of my improved pulley bracket partly broken away. Fig. 8 is avertical transverse section through the same, and Fig. t is a section taken on line H of Fig. 2.

In carrying out my improved invention I employ a frame A formed of two sections, A, A having depending apertured lugs A through which passes a bolt B for securing the sections together. The section A of the frame A is provided with an angled upper end, A", adapted to be secured over the end portion of the cross arm M, secured to the post D by a bolt M as clearly shown in Fig. l, and in this figure I have shown a pair of pulley brackets carried by the cross arm, one being arranged at each end of the arm in such a manner that the same can be used for supporting the leadways of the cable.

The section A of the frame A terminates in a horizontal extension, E having an aper ture formed therein through which extends a guide rod F which extends upwardly therefrom as clearly shown and may be extended over the top of the post and connected to the bracket upon the other end of the cross arm as shown in dotted line, but I have found that in most cases that a guide rod of the length shown is sufficient to catch and guide the cable back on to the pulley when the same jumps. The bracket upon the other end of the cross arm is an exact duplicate of the bracket above described and the description of one is sufiicient for both.

The side bars of the sections A, A of the frame A are thickened as shown at G, having outwardly and downwardly extending lips H which are spread apart as fully shown so as to form beveled guiding portions for guiding the arm of the carrier through the same so as to prevent any danger of the arm, becoming caught in the frame, and it will be seen that these lips diverge in such a manner that the arm will pass through the same smoothly. The sect-ions A, A are aperturedas clearly shown in which is mounted a bolt I, forming a shaft for a pulley J which is mounted thereon between the sections and on which the operating cable is adapted to travel and it will be seen that the enlargements G and the lips H extend over the peripheral edges of the pulley in such a manner that the cable will be prevented from jumping off of the same unless 'it moves in a vertical line and at the same time the arm can readily pass between the lips over the pulley. The enlargements G are rounded or beveled as shown so as to guide the cable back on to the pulley in case the same should accidentally jump off.

The lower end of the guide rod F is provided with an eye F which is secured over the outer end portion of the bolt I as clearly shown for holding the guide rod in its correct position. F or supporting the cross arm M and to provide guide members for conveying the cable back into the pulley bracket in case the cable should jump toward the post, I provide a guide rod or member C which is provided with a central eye C formed by coiling the same through which a bolt or screw end is adapted to pass for securing the same to the post D and the ends of the guide members G extend down through openings formed in the angle ends 91 of the sections A of the fame A and duough bores formed in the cross bar M and have their ends threaded and secured by nuts C as clearly shown.

The guide member C and guide rod F diverge as clearly shown from the upper ends of the section A, if so as to form inclined guide members for guiding the operating cable back into the bracket if the cable should by any means jump out of the same and it will be seen that by this construction the cable is carried back into the pulley by its own weight.

VJhat 5 claim:

1. A pulley bracket comprising a frame formed of two sections having a pulley interposed bet-ween the same, a cross arm for supporting said bracket and diverging members extending upwardly from the respective sections of said frame. forming a guide for the cable.

2. A pulley bracket comprising a frame formed of two sections each section being provided with outwardly extending lips, a pulley mounted in said frame, under said lips and diverging members extending upwardly from the respective sections of said frame.

3. A pulley bracket comprising a frame carrying a pulley cross arm for supporting said bracket, diverging guide members connected to said frame, and oppositely disposed depending diverging lips, carried by the side bars of said frame, extending over said pulley.

4E. The combination with a supporting post carrying a cross arm, of brackets carried by the ends of said cross arm, pulleys mounted in said brackets, a guide member connected to said post and to said bracket, :1 guide rod extending upwardly from each of said pulley brackets, said guide members diverging forming inclined guide members.

i-"r pulley bracket comprising a frame formed of two sections provided with apertured lugs, a bolt passing through said lugs, the side bars of said sections being provided with thickened portions, having outwardly projecting depending and diverging li-ps, a pulley mounted in said frame under said lips and thickened portions, an inclined guide member connected to the inner section of said frame, and an inclined guide rod connected to the outer sect-ion of said frame.

6. In a device of the kind described, the combination with a supporting post, of a cross arm connected to said post and carrying bracket frames at its ends, pulleys mounted in said frames, guide members formed on the side bars of said frames over said pulleys, a guide member having a central eye secured to said post above said cross arm and having its ends connected to the cross arm at the junction of the brackets, and guide rods carried by the outer section of the brackets.
