SPECIFICATION forming part of Letters Patent No. 633,978, dated September 26, 1899. Application filed April 2, 189B. Serial No. 676,229. (No model.)

To all whom it r11/Coy concern,.-

L Be it known that I, GEORGE D. XVILSON, a

citizen of the United States, residing'at Pom-vv eroy, in the county of Garfield andy State of Washington, have vinvented a new and use-y ful HorsePower, of which the following is a specifications y l* The present invention is designed chiefly to increase and prolong the life and period of usefulness of that class o f motors known as f horse-powers, the principal features being. to equalize the strain upon the vertical shafts, which are in mesh withv the line-shafting, by means of which motion is transmitted tothe machinery to be driven, thereby obviating a stripping of the cogs and an unequal strain of said vertical shaft in its bearings.

Other objects and advantages will appear in the course of the subjoined description, and in order that the details of the construetion may be fully comprehended reference is to be had tothe drawings hereto attached, in, which corresponding parts are indicated by and referred to in the following description by the same reference characters.

For a full understanding of the merit-s and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various lchanges in the form, proportion, ,and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which-'- Figure 1 is a top plan view of a horsepower, showing the application of the invention. Fig. 2 is a central longitudinal section thereof on the plane indicated by the dotted line 3 3 of Fig. 1. Fig. 3' is adetail view in perspective of a bearing for one of the idle or power-transmitting gear-wheels- Fig. 4 is a transverse section about on the line XX of Fig. 1.

The bed of the horse-power consists of a frame composed of longitudinal and trans.

verse bars firmly connected, forming a substantial structure. Transverse bars-1 are ap- 'plied to the end portion of the bed or base2 and are connected intermediate oftheir ends bymeansof abridge-tree 3. A vertical shaft bridge-tree 3.

4 is located about centrally of the base'and receives the master-wheel 5, which is journaledupon the upper end thereof and which is internally toothed, The sweep (not shown) to whichthe horse or team is. to be hitched is applied to the master-wheelin any of the usual ways, which are wellnnderstood in the art. The line of shafting 6, extending lengthwiseof the base, is journaled in hearings applied to the cross-timbers thereof and is supplied with `pinions 7, which intermesh with .gear-wheels 8, applied to the lower ends of vertical shafts 9, located at the ends of the These vertical shafts 9 are stepped in bearings applied to cross-timbers of the bed or base 2, and their upper ends arejonrnaledin plates 10, secured to the terminals of the'part 3. Pinions 11 are secured to the upper ends of the vertical shafts 9 and 'receive motion from the master-wheel through theintervention of idle or power-transmitting gear-wheels 12.

' The pinions 11 are located at diametrically vopposite points with reference to the masterwheel and a pair of idle or power-transmitting gears 12 is provided for each pinion, the wheels constituting each pair of gear-wheels 12 being located upon-opposite sides of the respective pinions 11 and interm'e'shing therewith and with the internally-toothed portion of the master-wheel. l This disposition of the e pairs of gear-wheels `12 equalizes the strain l upon the pinions 11V and centralizes them be tween the' contiguous portions of the gearwheels `12 in mesh therewith, thereby preventing wearing and stripping of the cogs of 'the pinions and obviating the tendency to cant the vertical shafts 9 and cause them to Wear unevenly in their bearings and to get out of plumb, which would'be objectionable and cause the intermeshing gear elements 7 and S to bind and soon wear out, besides detractingmaterially from the effectiveness and power of the motor. It will also be observed that a greater number. of teeth of the pinions 11 are brought into action, thereby enabling smaller pinions 11 being used, which is Ade sirabl'e in motors of this type. Y

Plates 13 are provided with stub-axles 14,

y upon whichrthe gear-wheels 12 are mounted.

These plates haveadj estable connection with the transverse bars 1, so as to be moved to IOC secure the proper meshing of the cogs with the oogs of the master-wheel andthe pinions l l. Slots 15 are formed obliquely in the corner portions of the plate 13 in such a manner as to admit of the gear-wheels 12 being moved so as to bring their teeth into meshing relation with the teeth of the master-wheel and the pinions 11 with a greater or less degree, as may be required. In this connection it is to be noted that ifthe plates 1 3 were moved laterally orin a direction at right angles to the line of the bridge-tree the gear-wheels 12 would be moved into engagement with the master-wheel and out of engagement with the pinion, or vice versa. On the other hand, if the plates 13 were moved in lines parallel with the bridge-tree an adjustment thereof .with reference to the pinions 11 could not be secured. It is essential, therefore, that the plates 13 be moved on lines intermediate of these two positions in order to secure a proper meshing of the gear elements, as will be readily comprehended.

V-shaped plates 16 have their inner arms overlapping and pivotally connected to the end portions of the bridge-tree 3 and have their outer arms formed with slots 17, through which bolts pass to adjustably connect them with the longitudinal beams ofthe base. The upper ends of the stub-axles 14E pass through openings in the axle ends of the V-shaped plates and receive pins i8, by means of which said plates are prevented from vertical displacement.

When the master-wheel 5 is set in motion, it causes the gear-wheels l2 to correspondingly turn upon the stub-axles 1t and transmit motion to the pinions 11., and from thence to the line of shafting 6, through the instrumentality of the intervening gearing, as herein described, and illustrated in the accompanying drawings.

The vertical shafts 9 when Yproperly positioned are not subjected to side stress, inasmuch as the pairs of gear-wheels 12 exert an equal pressure against the opposite side of the pinions 1l. Hence the gearing will Wear uniformly and the horse-power be more durable and lasting than if the gear-wheels 12 were dispensed with and the pinions ll caused to mesh directly with the cog-teeth of the master-wheel 5, as commonly practiced.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a horse-power, substantially such as described, the combination with a suitable base, a master-wheel journaled thereon and a line-shaft, of a vertical shaft supported on the base independently of the master-wheel and geared to the line-shaft, bearing-plates fixed to the base on opposite sides of the vertical shaft, and a pair of transmitting-pinions journaled ou the bearing-plates independently of the master-wheel and disposed on opposite sides of the vertical shaft, said pintain the axes of the shaft and master-wheel in parallel relation.
