SPECIFICATION forming part of Letters Patent No. '7' 1 5,250, dated December 9, 1902.

Application filed January 27, 1902. Serial No. 91,425. (No modell) To a/ZZ whom, it indy concern:

Be it known that I, RICHARD N. EDWARDS, a citizen of the United States, residing at Williamsville, in the county of Wfayne and State of Missouri, have invented a new and useful Hand-Brake for Cars, of which the following is a specication.

This invention relates generally to carbrakes; and the object of the invention is to provide a brake-operating mechanism capable of being operated by hand either from the top of the car or the side thereof.

With these objects in View the invention consists in the novel features of construction and combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forminga part of this specication, Figure l is a perspective View showing the practical application of my invention. Fig. 2 is an enlarged detailed perspective View. Fig. 3 is a detail view showing the reversible pawl. Fig. 4 is a vertical sectional view showing the relative arrangement of the combined pawls and gears. Fig. 5 is a detail in elevation showing the weight for holding the locking-pawl in position. Fig. 6 is a detail perspective view showing the several parts of said pawl and weight detached, and Fig. 7 is adetail perspective View of the journal-bracket.

In carrying out my invention I employ a combined journal-bracket A, having the vertical bearin A and the horizontal bearing A2,said bearings being connected by means of an angular arm A3, from which extend the brace-rods A4, by means of which the bracket is attached to the bottom timbers of the car. A vertical shaft B is journaled in the vertical bearing A', the upper end of said shaft being journaled in a bracket C, the construction of which will be described hereinafter. A beveled gear D is mounted upon the shaft B and rests upon the bearing A', said beveled gear having an integral ratchet-disk D' arA ranged beneath the same,said disk having the peripheral ratchet-teeth D2 and the upper or crown ratchet-teeth D3. A horizontal shaft E is journaled in the horizontal bearing A2 and carries a beveled gear F upon its inner end, the teeth of said' gear F meshing with the beveled gear D. The ratchet-wheel F is a double reversible pawl II, which'is adapted to engage the ratchet-wheel F', said pawl having the points H' and H2 and the enlarged or weighted portion H3, the pivot IrlAL being,r arranged in advance of yboth points H and H2, so that no matter which side of the pivot the Weighted portion rests upon either the point H or H2 will engage the ratchet-wheel. A pawl I is pivoied toa bracket K and is adapted to engage crown ratchet-teeth D3 of the disk or Wheel D', said pawl having a weighted portion l', which normally holds it out of engagement with the said teeth. A weight K is pivoted between the ears K2 of the bracket K and is adapted to rest upon the end of the pawl I for the purpose of holding the same in engagement with the ratchetteeth D3. The bracket C, which is fastened to the end of the car, comprises a central portion C', in which the upper end of the shaft B is journaled, and the transversely-slotted portion O2, in which the upper end of the 1ever Gworks. The lower end of the shaft B is connected to the brake mechanism by means of the chain L.

M indicates the hand-wheel,arranged upon' the upper end of the shaft N, said shaft being journaled in brackets upon the end of the car and provided at its lower end with a clutch joint N', by means of which connection is had with the upper end of the shaft B.

By means of the device herein shown and described a brake can be applied either by turning the hand-wheel M at the top of the car or by working the lever G from the side of the car. It will also be understood that the operation of the brake mechanism by the hand-lever will not interfere with the operation of the hand-Wheel at the top of the car, nor will the operation of the brake mechanism by means of the hand-wheel at the ltop of the carrinterfere with or operate the handlever mechanism.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A brake-operating means, comprising a brake-shaft having a combined gear and ratchet Wheel mounted thereon, the u pper end of said shaft being operatively connected to a hand-Wheel shaft, a gear-wheel journaled transversely to the first-mentioned gear and meshing therewith, said last-mentioned gear having a ratchet-wheel integral therewith, and a lever carrying a pawl adapted to engage the said ratchet-Wheel, substantially as described.

2. A brake-operating means comprising a brake-shaft provided with means at its upper. end for connection with a hand-wheel, a combined gear and ratchet Wheel mounted adjacent to the lower end of the brake-shaft, a pawl pivoted adjacent to the said combination gear and ratchet wheel, a weight adapted to bear upon the said pawl, a combination gear and ratchet wheel arranged transversely to the first-mentioned gear and ratchet wheel,

the gear-teeth being adapted to mesh, an operating-lever and pawl connected thereto, substantially as shown and described.

3. In a device of the kind described, the combination with the brakeshaft, of the combination gear and ratchet Wheel arranged thereon, a pawl pivoted adjacent to the said combination gear and ratchet and provided with a Weight at its lower 'end to normally hold the upper end lout of engagement, and a pivoted weight adapted to bear upon the free end of the pawl, substantially as shown and described.

4. In a brakefoperating mechanism, the combination with the horizontal shaft having a combined gear and ratchet arranged thereon, an operating-lever and a double reversible pawl pivoted to the lever and adapted to engage the ratchet, substantially as shown and described.
