The gears 17 mesh-with the teeth 1-2' of the gear and are positively driven thereby ;the manner tov 'be herein afterjeigplai'ned. l Z

A herizental'ly disposedjtop brace 05. w:

I porting ember r fine share: 14, ,i dieated at 1 9-, is clam ed or otherwise secured its ends -;to the frame -T-his-upper frame 14, This shaft is threaded, as 21, for a short distance firom the extension 20 thereon to receive a clampingnut =22. 'A plurality of washers 28 re adapted to be' arranged 7 upon the shaifit la-between the-nut 22 and a gear member '24 loosely arranged upon said shaft. gear memher rests upon annular shoulder 25 formed upon the shaft 14: so that s-aid member;- will not -"be frictional-jly engaged" or clamped against the "lower bracing -member 15, but will be tightly se cured upon the shaft 14C for rotation therewith. D-his member 24 is prowided upon its v 5 member isprovided with an opening to re-' v ceiye the reduced -upper-end- 2O of the start periphery with gear teeth 26, and is also formed with an annular series of teeth 27 upon its upper surface, said latter teeth being preferably tapered longitudinally, as shown, for engagement by a miter pinion 28 fixed upon the driven shaft 29. It is to be understood, however, that the invention is in no sense limited in this particular regard, as the teeth 27 can obviously be otherwise formed for engagement by various types of power transmission, gears orv pinions. The driven shaft 29, through the medium of which power is transmitted for the operation of a machine, is mounted in a suitable supporting bracket 31 arranged upon the frame 5. 1

A casing or housing 32 is fulcrumed upon a pin 33 fixed in the base 6 of the frame. The body of this casing is provided with a longitudinally extending socket 3% opening upon one end thereof, and upon the opposite walls of this socket, lugs 35 areformed.

' 36 designates the operating lever provided in opposite sides with recesses 37 to receive the lugs 35. In the end face of an enlarge ment 38 formed in the body of the housing or casing, a groove or channel 39 is formed to receive the dogs l0. Thesedogs are of a general longitudinally tapering form and have their smaller ends disposed respectively, in the opposite ends of the channel 39. The small ends of the dogs are provided with pivot lugs 41 for engagement in openings 12 formed in the body of the housing. These lugs also project above the upper face of said body and are adapted to be received in openings provided in a cap or cover plate 43 which is removably securedupon the body by meansof suitable screws, indicated at er. One of the dogs 40, at its outer end, is recessed or reduced in width to form an extension 45 thereon, while the other of said dogs is also notched or recessed toproduce a lug or tooth 46 and a narrow longi- 'tudinal extension 47. These dogs 40, as

clearly shown in Fig. 2 of the drawings, are inclined toward each other and are yieldingly held against the ratchet 10 by means of springs 48 mounted in the enlarged end of the body of the housing 32. These springs are connected at one of their ends to the respective dogs and one of said springs is connected at its other end to the plug l9 which is threaded in the body of the pivotally mounted lever housing 32. It will be readily understood, from this construction, that when the lever 36 is oscillated upon the pivot 33, the outer ends of the dogs 4L0 will alternately engage the teeth of the ratchet wheel 10 so as to impart a constant rotary movement thereto in one direction'while a lever is manipulated; This ratchet wheel being fixed to the internal gear 11, will obviously also rotate said latter gear, and rotation will thus be transmitted throughthe intermediate gears 17 mounted upon the brace member 15,to the perpendicular shaft 14. by the engagement of said gears with the pinions 18. The gear member 2 1 being fixed upon said shaft in the manner above pointed out, it will be seen that the shaft 29 is positively driven through the engagement of the pinion 28 thereon with the annular series of gear teeth 27 upon the upper face of said gear member. Any desired number shafts may be geared to this member, or the driving force may be transmitted through the engagement of a gear with the peripheral teeth 26 upon said member 2 1. In order to reverse the direction of rotation of the driven shaft 29, it is only necessary to remove the nut 22 and the washers 23 on the shaft 1% and then remove the member 24: and replace the same in an inverted position, as illustrated in dotted lines in Fig. 1, or with the teeth 27 disposed above the pinion 28 and in engagement therewith.

From the foregoing description, taken in connection with the accompanying drawings,

it is believed that the construction, manner of operation, and the several advantages of my invention will be clearly and fully understood.

The mechanism consists of a comparatively few elements which may be easily and quickly assembled or disassembled, and provides a highly durable and positively operating construction, whereby a machine operating shaft may be driven at a relatively high speed with comparatively little manual labor by the operator. It will of course be obvious that the ratios of the several gear elements may be varied, as desired, so as to rotate the driving shaft at a predetermined speed. It is also to be understood that while I have referred to a particular means for mounting the central perpendicular shaft of the-several cooperating elements, this portion of the apparatus is susceptible of considerable modification. I therefore reserve the privilege of resorting to all such legitimate alterations in the form, proportions, and arrangement of the several parts as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus described the invention, what is claimed is 1. In a power transmission gearing, a driving shaft, a driven shaft, a reversible gearmember on said driving shaft provided with an annular series of gear teeth upon one face, apinion on the driven shaft, means for securing said gear member upon the driving shaft with its teeth in engagement with the teeth upon either side of said pinion to rotate the driven shaft in either direction, and means for rotating said driving shaft. I

2. In a power transmission gearing, a driving shaft provided with an annular shoulder, a driven shaft, a gear member arf ranged upon the driving shaft and provided with an annular series of teeth upon one face, a pinion upon the driven shaft to mesh with said teeth, a nut threaded upon one end of the driving shaft, a plurality of washers arranged between said nut and the gear member to clamp said member against the shoulder and with its teeth in engagement upon one side of the pinion of said driven shaft, said member being adapted to be're moved and reversed upon the shaft and the spacing washers arranged between the same and the shoulder of said shaft, whereby the teeth of said member may be'engaged upon a the opposite side of said pinion and rotation of the driven shaft reversed, and means for rotating the driving shaft.

3. In a power transmission gearing, a vertically disposed driving shaft, a support therefor, a rotatable element, an internal engagement with either one of opposite sides -'of the pinion, whereby the rotation of the signature in the presence of two witnesses;

driven shaft maybe reversed, and manually operable'means' for positively operating said rotary element. 7

4:. In a power transmission gearing, a driving shaft, a driven shaft, a'reversible driving member removably 'mounted upon said driving shaft, a power transmission element on the driven shaft, a plurality of spacing collars uponthe driving shaft to retain the driving member thereon in cooperative engagement in. either of its positions with the element on the driven shaft, and

means for rotating saiddriving shaft.

5. In a power transmission gearlng, a

driving shaft, a driven shaft, a reversible drivingmember removably mounted upon the driving shaft, a power transmission element fixed on the driven shaft, a plurality of collars removably mounted upon the driv-i ing shaft to retain the driving member thereonin eitherIof its positions in cooperative engagement. with said driven element, a nut threadedupon the driving shaft to clamp said driving member and the collars together for rotation with said shaft, j

and means for rotating said driving shaft;
