JAMES L. RECORD, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-HALF I TO JOSEPH GARRETT, OF SAME PLACE.

HORSE-POWER.

SPECIFICATION forming part of Letters Patent No.368,970, dated August 30,1887.

Application filed March 28, 1887.

To all whom it may concern.-

Be it known that I, JAMES L. REooRD, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Horse-Powers, of

which the. following is a specification.

My invention relates particularly to horsepowers for heavy work when two or more horses are used; and it consists, generally, in a mas- 1o tor-wheel operated by the sweep and meshing with two pinions on two separate shafts running radially to the master-wheel, these shafts being provided at their inner ends with bevel-gears, which mesh with a pinion common to both upon the main power-transmitting shaft. By

this means I am enabled to distribute the strain more equally upon the master-wheel and upon the pinion of the main transmitter-shaft, and also to increase the speed of the said shaft.

My invention further consists in the construction and arrangement hereinafter described, and particularly pointed out in the claims.

In the drawings, which form a part of this 2 5 specification, Figure 1 is a central vertical section 011 the line of the two counter-shafts. Fig. 2 is a vertical section on a line with the main or power shaft. Figs. 3 and 4 are details showing the construction of the step and shaft bearingS.

In the drawings, 2 represents the frame of the machine.

4 is a step-casting centrallylocated and supported upon suitable timbers of the frame 2. 5 This casting is preferably made as shown in Figs. 3 and 4, having bearings 5 for the horizontal shafts, and also a bearing,.6, at right angles to the bearing 5, which supports the inner end of the main power-shaft. These three bearings are on the same horizontal plane, and are provided with suitable caps and bolts, and are connected by the plate 7, which also forms a support and means for attachment to the frame. The step or vertical bearing 9 for the piece master-wheel shaft is also formed in one with the horizontal bearings.

Vertical plates 8 extend downward from the plate 7 on the inside-of the frame-timbers, and are connected by the bridge 10, upon which Serial No. 232,691. (No model.)

the step is formed. I prefer to form these bearin'gs in one piece,'for convenience in construction and to assure their being kept in line.

15 is a vertical shaft resting in the step and held in position by and revolving in suitable bearings, 17, upon the frame.

18 is a master-wheel hung upon the shaft 15 and revolving with it.

20 are pinions diametrically opposite each other, the teeth of which mesh with the teeth of the master-wheel.

The pinions 20 are hung upon countershafts 21, which revolve in bearings 5 and 22 upon the frame. These shafts are set radially to the shaft of the master-wheel, and upon their inner ends are secured the bevel-gears 24. These gears may be made of any suitable size to give the required speed. The pinion 25 upon the main or power shaft 26 is common to both the gears 24, which are arranged to mesh with the said pinion upon opposite sides. The shaft 26 revolves in the bearings on the step or center casting, and may be provided with other bearings necessary for its support.

The sweep-head 30 is located at the upper end of the shaft 15 in the ordinary manner.

Bearing-wheels 31 may be placed above the pinions 20 and arranged to bear upon the master-wheel for the purpose of keeping it steady.

The operation is as follows: Power is applied to the sweeps attached to thesweep-head, and by this means the shaft 15 and the masterwheel are revolved. This imparts motion to the pinions 20, together with the shafts 21 and bevel-gears 24, attached thereto. The opposite shafts, being driven from opposite sides of the master-wheel, will revolve in opposite directions; but this motion is again brought to act in the same direction by the pinion 25,.

which is common to both gears, and upon the opposite sides of which they mesh. It will be seen that by this arrangement a double contact is made with the master-wheel, thus balancing the machine and relievingthe strain by onehalf, or allowing double the amount of power to be transmitted with the same strain as compared with the machine using a single pinion. The same benefit is derived in transmitting the power back to the main shaft. The gears, actthe gears 20, meshing with the master-wheel,

and upon their inner ends with the bevel-gears 1 5 24, and the power-shaft 26, mounted in said bearing 6, and provided on its inner end with the bevel-gear 25, meshing with both of said gears 24, substantially as described.

In testimony whereof I have hereunto set 20 my hand this 18th day of March, 1887.

JAMES L. RECORD.
