Specification of Letters Patent.

Application filed September 26, 1914. serial no; 863,706;

ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

My invention relates to improvements in br'ake'sof the type adapted for use inconnection with traveling carriers that are slidable upon cables and has for its primary object to provide a novelly constructed brake attachment that may be readily and easily attached to carriers and will operate to retard the movement of the carriers or hold the carriers against movement altogether, when desired.

Another object is toimprove brakes of the character described so as to render them i more practical, reliable and eiiicient in operation and inexpensive to manufacture.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims.

With reference to the drawings, wherein n "18 is detachably connected with the bar 5 and is designed to engage one end of the I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a fragmentary side elevation of a part of a carrier showing my improved brake attachment thereon and in operative position also in inoperative position in dotted lines, Fig. 2 is a sectional view taken through a part of the carrier and showing the brake lever and shoe in top plan, and Fig. 3 is a detail side elevation of the hook for supporting the lever when the brake is not in use.

Referring to the drawings by characters of reference, the numeral 1 designates a suspension cable for a carrier designated '2 as anentirety. The carrier 2 is shown only in part and is suspended by a pulley or pulleys 3. Thepulley 3 is mounted upon the cable 1 and connected with the pulley 3 is a depending receptacle supporting arm 4. :In the type of carrier which is illustrated in the drawing in part, the carrier consists of two upright members 4 and two pulleys 3.

The IqSI-ight members 4 are connected bya horizontal 'c'ross or connecting bar 5 that is shown in part inthe drawings. 1

My improved brake attachment comprises a brake lever designated 6 as an entirety that is pivoted intermediate itsends as at 7 to a clamping member 8 on one side ofs'aid clamping member. The clamping member 8 comprises a plate 9 that is pivoted to the lever 6 and a detachable plate 10 that is secured" to the plate 9' by means of bolts .11

Patented Au 24', 1915 which have nuts 12 turned on their threaded terminals.

l The clamping member 8 is designed to engage and clamp upon the rod 4 at a point adjacent the upper end of said rod. The I lever 6 is bowed as at 13 at a point between one end and the pivot point 7 thereof and at the free end of said bowed portion 13 is secured a brake shoe 14 that is approximately U-shaped in cross section and engages the cable 1. The curving of this lever 16 brings the free end of the curved portion into a position, so that the shoe 14 will be brought to bear against the cable 1.

A helical retractile spring 15 is secured to one end as at 16 to the rod or bar 5 and at its other end to an eye 17 carried on the bowed portion 13 of the lever 6. This spring 15 normally holds the brake shoe 14 into braking position. A hook designated lever 6, said end being notched as at 19' so as to receive the lower part of the hook and securely hold itself in position. The bowed portion 13 isofiset so as to not interfere with the spring 15 or adjacent parts of the carrier. r i

p In operation when it is desired to release the brake from position as shown in Fig. 1, that is, braking position, the lever 6 is moved upwardly and the notched end 19 thereof placed within the hook 18. It will be readily seen that the carrier will be held against movement if desired by the use of my improved brake.

Inpractice, I have found that the form V of my invention, illustrated in the drawings and referred to in the above description, as] the preferred embodiment, is the most ,efiie Copieso! this patent may be obtained for I cable.

tion and arrangement of parts may be resorted to, when required, without sacrificing any of. the advantages of my invention as set forth.

1 What is claimed is V 1. In a brake the combination with a cable, and'a pulley or wheel arranged to run on the cable, of a carrier suspended fronr the pulley or wheel and a brake lever pivoted-jat a point intermediate of its ends to the carrier at'a point below the axis of the pulley or wheel and provided at one, end with a shoe arranged to engage the under side of the cable belowthe pulley or wheel to cooperate therewith in clamping. the said 2. In a brake the combination with a cable, and a pulley or wheel arranged to run on the cable, of a carrier including a supporting bar depending from theipulley or wheel and a horizontal barconnected with the supporting bar, a clamp secured to the supporting bar below the horizontal bar and provided with a pivot located below the axis of the pulley or wheel, a brake lever fulcrumed at an intermediate point on the said pivot andprovided at one end with means V, FRED.
