Application iiled November 23. 1897. Serial No. 659.560. (No model.)

United States, residing at Shiloh IIill, in the county of Randolph and State of Illinois, have invented a certain new and useful Improvement in Brakes for Hay-Frames and the Like, of which the following is a specification.

Our invention 'relates to a new and useful improvement in brakes for hay-frames and the like, and has for its object to provide an exceedingly simple and edective apparatus of this description by means of which the brake-shoes may be applied to the wheels of a' Wagon from-various positions of the operator; and a further object of our invention is to Irvovide for the fallingor swinging of :the

upper portion of the brake-lever out of the way when occasion may require by the load or from other causes.

A still further object of our invention is to put the locking and unlocking of the brake under perfect control of the driver, and also to permit the adjustment of the upper portion of the lever to any desired position by the driver from the upper end of the brake-lever; and a still further object of our invention is to provide for the various adjustments necessitated by the slack in the brake-rod or the depth of the frame. 4 'i YVith these ends in View this invention consists in the details of construction and combination of elements hereinafter set forth and theh specifically designated by the claims.

vIn order that those skilled in the art to which this invention appertains may understand how to make and use the same, the con-- strue "m and operation will new be described in detaihreerringto the accompanying drawings, forming a part of thisspeciication, in whi'che Figure l is a bottom plan of a wagonhaving a hay-frame thereon and showing the arrangement of the brake bars and shoes relaftive'igto the wheels, as well as the brake-rod connecting said bars with the brake-lever; an elevation of the brake-lever andits toothed segmental stand, the cross-bar to which said stand is bolted being in section; Fig. 3, an enlarged View of the lower portion of the lever, one side thereof being'sectioned away, so as to clearly illustrate the manner of operating the locking-dog and adjusting-cap; and Fig. 4, an edge view of the portion of the apparatus shown in Fig. 3.

In carrying outv our invention as here ein bodied, A represents a hay-frame, which is supported in the usual manner upon the axles B, the latter having jonrnaled thereon the wheels C and D, and to the under side of this frame are pivoted the brake-bars E, as indicated at F, the outer ends o t said bars carrying the shoes G, adapted to be forced against the wheels I), while the-innerv vends of these bars are coupled by means of the links l-I to the brake-rod I, so that when said rod is drawn in the' direction of the arrow marked adja- -ccrrtthereto theV brandbare will fnreefthe'f shoes firmly against the wheels, thus accomplishing the result intended.

A stand or bracket J is bolt-ed to the crossbar K and consists of a single piece so formed as to produce the toothed segment L. The brake-lever M consistsl of two metal bars arranged parallel side by side and is pivoted at N to the bracket J and is attached at its lower end by the bolt I, which passes through two of the series of holes'O and Q, to the brake-rod I.

for which the brake is' Thus when the brake-lever is swung in the proper direction this rod will be drawn upon and the brake-shoes forced against the wheels D, as before'set forth.

An operating-lever R is pivoted at S between the side bars of the brake-lever M, and

this operating-lever is preferably of wood, having secured to the lowerend thereof.E two metal strips U, which are welded together at their lower ends, as indicated at II,'wl1ere they pass between the side bars of brake-lever andare thus pivoted. A ratchet-dog V is also pivoted between the side bars of the brake-lever and adapted to engage with the teeth L, so that when the brake-lever is swung in such manner as to apply the shoes ,it may be locked yin this position, thereby relieving theloperator of the necessity of constantly holding the level` in this position; but when it becomes necesr`sary to release the brake-lever this is accomplished by means of a hand-lever WV, which is IOO pivotcd to the upper end of the operatinglever and connected to the ratchet-dog oyV means of 'a wire W and a. chain W2, which forms a continuation of said wire and passes through the eye X, formed upon the pin S,

brake-lever, as before described, it is necessary that it'shall be held rigid therewith in order that power may be transmitted to said brake-lever, and this we accomplish by the use of a segmental rack Z, which is pivoted at a between the strips U andhas formed therein the notches b, adapted to engage with the bolt d, which latter is also utilized tosccure the upper ends of the side bars of the brake` lever in position. I

A spring e 'is coiled about the bolt d andso attached to the rack-har as to'norrnally hold itin engagement with the bolt a. Thus when the operating-lever is adjusted to any desired position it will therefore be held in this position by the engagement of one' of the notches b with thebolt d, and when a readjustment of the operating-lever is desired the handlever f, which is pivoted to the upper portion of the .operating lever and connected by means of the wire g to the rack-bar, is manipulated towithdraw the rack-bar out of engagement with the bolt d. This last feature of our invention is exceedingly important, since it permits the adjustment of the operating-lever to a variety of positions, thereby enabling the operator to manipulate the brake-lever Without inconvenience from the load or otherwise, and when the operatinglever is swung from one position to another. it is to benoted that the -chainW2 is not af- 'fected by this movement, since it passes throughthe eye )L 'at the center of movement of said operating-lever, thus maintaining the .chain in its taut or slack condition at all times. 1

Haring thus fully describedour invention, what Weeclaim as new and useful is-4 1. A brake for hay-frames consisting of suitable brake-bars, shoes carried thereby, a

rod connected therewith, a. segmental rackstand attacnedto the frame, a brake-lever pivoted to said stand, and attached at its lower end to said rod, a ratchet-dog pivoted to the brake-lever and adapted to engage the teeth of the stand, an operating-lever pivoted4 s v l 611,096

to the brake-lever, a segmental rack-bar pivoted to the -operating-lever and adapted to engage the bolt carried by the brake-lever,

` 2. A brake of the character described consistin g of two brake-bars pivo'ted to-he frame, shoes carried by the outer ends of said bars, a brake-rod, means for coupling said rod to the brake-bars, a segmental rack-stand se-l cured to the iframe, a brake-lever pivoted to said stand and attached at its lower end to the Abrake-rod, a ratchet-dog pivoted tothe hrake-levei-,a spring for holdingsaid dog in engagement with the segmental teeth, an operating-lever pivoted to the brake-lever, a'

rack-bar pivotedto the operating-lever and adapted to engage with a suitable'bolt carried by the brake-lever, ahand-lever YV, means for connecting said hand-lever with land means for throwing the ratchetfdog and yrack-bar into and outof activity, as specified.

the ratchet-dog, a hand-lever f also pivoted to the operating-lever, and means for connecting the last-named hand-lever to the rackbar, substantially as and `for the purpose set forth.

3. Theherein-described combination of the brake-bars E pivoted to the underside of the frame, shoes carried bysaid bars and adapted to act upon the wheels, a brake-rod, links for connecting said rod to the brake-bars, a segmental stand secured to the frame, a brakelever pivotedto said stand and attached to the brake-rod, teeth formed upon the segmental portion of the stand, a ratchet-dog pivoted to the brake-lever and adapted to engage said teeth, a spring for normally holding said dog in engagement with said teeth, an operating-lever nivoted to the brake-lever, a rack-bar pivot bar in engagement witn suitable bol-t carto the operating-lever, a' spring adapted to normallyhold said rackried by the brake-lever, a hand-lever f piv- `oted to the upper end of the operating-lever,
