UNITED STATES PATENT OFFICE.
CHARLES A. MILLER, or READING, PENNSYLVANIA.
ADJUSTABLE RATCH ET DEVICE.
SPECIFICATION forming part of Letters Patent No. 698,212, dated April 22, 1902.
Application filed February 11, 1902. Serial No. 93,484. (No model.)
To aZZ whom, it mag concern:
Be it known that I, CHARLES A. MILLER, a citizen of the United States, residing at Heading, in the countyof Berks and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Ratchet Devices; and I' do hereby declare the following 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.
This invention relates to improvements in an adjustable ratchet device intended moreparticularly for use on a brake-lever for antomobiles and the like.
The invention is particularly applicable to power-wagons, as stated, for the reason that it permits the brakerto be applied and held in any desired position without the necessity of continued foot-pressure, as is usually the case.
The invention is fully described in the following specification and clearly illustrated in the accompanying drawings, in which-.
Figure 1 is a side elevation of my ratchet device. Fig. 2 is a vertical sectional view taken on line X X of Fig. 1; and Fig. 3'is a plan View, partly in section, on line Y Y of,
ig. 1. V
The ratchet-frame A is of a construction; such as is frequently used, being in the form of an arc and provided with the usual teeth a in its upper face. The operating arm B passes through the longitudinal opening a in said frame and extends some distance above it. To the upper end of this arm B, Iprovide a shoe 0, pivoted to said arm at a pointcand carrying a foot-plate D. To the lower end of said shoe 0, on one side thereof, is secured pivotally a depending adjustable rod E, having an eye e formedinjits lower end, through which a pin e passes, and is capable of adj ustment in a slot 71. in the body of the pawl F. This pawl is pivoted to the arm B a short distance above the face of the toothed frame gagement with said teeth. a.
slot it that the foot-plate D will require only a given movement before the pawl F will be raised free from the teeth a, andthis may be adjusted to suit each individual operator.
Having thus fully described the invention,
what I claim, and desire: to secure by Letters Patent, is v p In an adjustable ratchet device, a toothed frame A having an elongated opening, an op- I crating-arm B extending through said opening, a pawl pivoted to said arm and adapted to engage the teeth on said frame, a shoe 0, a v
foot-plate D formed on said shoe, said shoe pivoted to the freeend of said arm, depending'rodE, and a pin securedito said rod E and adapted to engage a slot in said pawl, substantiallyas set forth. p Y g In testimony whereof I affix my signature in presence of two witnesses.
CHARLES 'A. MILLER.
