ALFRED F. SPAULDING, OF -NORTI-IFIELD, VERMONT.
DRlVlNG MECHANISM.
SPECIFICATION forming part of Letters Patent No. 704,220, dated July 8, 1902.
Application led April 25, 1901` To @ZZ whom, t may concern.-
Be it known that I, ALFRED F. SPAULDING, a citizen of the United States, residing at Northfield, county of IVashington, and State of Vermont, have invented a new and useful Driving Mechanism, of which the following is a specification.
My invention relates to improvements in grinding-machines in which ball-bearings operate in conjunction with a straight shaft.
The object of my improvement is, first, to provide means whereby the ball-bearings can all be brought to a bearing at once and held in place; second, to provide a machine which can be operated with very little friction. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure I is a view of the entire machine. Fig. 2 shows one side of the balance-wheel detached from the main machine; Fig. 3, the opposite side of the wheel and other appliances connected with the machine.
Similar characters refer to similar parts throughout the several views.
The stand A and leg B constitute the framework of the machine. Treadle C is connected with sprocket-chain D, operating over sprocket-wheel E, said sprocket-wheel being connected with balance-wheel F, which is belted to drive-wheel G. The downward and upward movement of treadle, connected as hereinafter described, constitutes the motive power that drives the grinding-wheel II.V Fig. 2 shows shaft I, passing through the hub of the balance-wheel J, and also cam-driving wheelK,whichis connected with the sprocketwheel with the usual pin or key. When adjusted for use, the cam-wheel is pressed down into countersink L, whose outer periphery is provided with corrugations. This countersink holds balls I, 2, and 3, which move between cam-wheel K and the corrugations shown in the hub of the balance-wheel. The forward movement of the machine with the balls l, 2, and 3 arranged as shown causes the balls to bind between the cam-wheel and the corrugationsin the hub of the balance-wheel, and both wheels (sprocket and balance wheel) move in the same direction; but when the sprocket-wheel is reversed the balls are loosened and roll backward with the cam-wheel Serial No. 57,509; (No model.)
without retarding the forward movement of the balance-wheel, and a continued forward movement of the balance-wheel is kept up by treadle or other similar power.
In the sprocket-wheel M there is a recess in the hub thereof, Whose outer periphery is larger than the inner, and placed in this recess are balls, which when pressed into place by a cap constitute aball-bearing on a straight shaft.
Balls shown below countersink L are contained in a recess in the hub of the balancewheel, the same as shown in the hub of sprocket-wheel, only the recess is smaller. The hub of sprocket-wheel is long and passes down through cam-wheel K, holding the balls in place shown below countersink Ii.
Detached plate N holds cam-driving wheel in place and is also shown and lettered in Fig. 3.
O is a sp1"ocketwheelplate follower and holds the balls there shown in place.
Sprocketwheel hub M and cam-driving wheel K are also shown detached from the main machine.
Fig. 3 shows shaft I protruding through the balance-wheel. Formed in the hub of this wheel is a recess fashioned like that in the hub of sprocket-wheel. Balls are placed in this recess and are held in place by fiat follower P. i
Q is an ad justing-collar held in place on the shaft by a set-screw.
In Fig. l the end of shaft I is provided with a collar R, secured to the shaft by a threaded screw; but it may be secured in any other convenient way. This collar is pressed down onto the cap, which holds the balls in place in the hub of the sprocket-wheel.
'Vhen all the arrangements connected with shaft I, as described, are in place in the hub of the wheels, collar R and adjusting-collar Q are brought into use conjoiutly, thus holding each part in its proper place between collars R and Q. Shaft I is then secured to frame A.
I-Iaving fully described my invention, what I claim, and desire to secure by Letters Patent, is
In combination, a wheel provided with a central shaft-opening and ball-recesses communicating therewith in opposite ends of the hub, a shaft located in said opening, balls located in said recesses and bearing upon said shaft, a Washer and collar mounted upon said shaft at one end of the hub to retain the balls in the adjacent recess, a sprocket Wheel mounted on said shaft, its hub being extended to form a closure for the other of said ballrecesses, said first-mentioned hub being provided with a corrugated countersink surrounding said sprockethub, a cam Wheel keyed to the latter hub and located in said countersink, clutch-balls located in the space between the cam and the first-mentioned hub, a follower to retain said clutch-balls in place, the other end of the sprocket-hub being pro- ALFRED F. SPAULDING.'
