JOSEPH W. ORIST, OF DETROIT, MICHIGAN.

MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed June 26, 1905. Serial No. 267,096.

To all whom, it ntcty concern:

Be it known that I, JosEPH W. ORIsT, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements inMechanicalMovements; and I do 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 mechanical movements.

The object of the invention is to provide a mechanical movement in which a shaft is rotated by means of link mechanism.

A further object is to provide means for reversing the direction of movement of the shaft.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side view of the mechanism embodyin the invention. Fig. 2 is an end elevation'of the same. Fig. 3 is a vertical sectional view on a line with the shaft. Fig. 4 is a vertical sectional view on the line 4 4 of Fig. 3. Fig. 5 is a side view of the opposite side of the drivegears to that shown in Fig. 1, and Fig. 6 is a vertical sectional view on the line 6 6 of Fig. 2.

Referring more particularly to the drawings, 1 denotes the shaft to be driven, and 2 and 3 denote sleeves which areloosely mounted upon the shaft 1, the inner ends of said sleeves being provided with clutchmembers 4 and 5. Free to slide upon the shaft 1 and to rotate therewith is a clutch-sleeve 6, on the opposite ends of which are formed clutch members or faces 7 and 8. The clutch-sleeve 6 is adapted to be shifted upon the shaft 1 by any suitable form of shifting-lever 9 to bring one or the other of the clutch-faces 7 or 8 into engagement with the adjacent clutch-faces 4 or 5 on the sleeves 2 and 3, thereby locking one or the other of said sleeves into engagement with the shaft 1.

Loosely mounted upon the sleeve 2 is a pair of spur gear-wheels 10 and 11, each of said wheels being provided in one side with an annular recess 12. In the recess 12 of the wheel 10 is arranged a clutch-disk 13, while in the recess of the wheel 11 is arranged a clutch-disk 14, said disks being fixedly mounted upon the sleeve 2. The disks 13 and 14 are cut away at equal distances around their peripheries to form radial cam-surfaces 15, between which and the inner wall of the an nular recesses 12 of the gear-wheels 10 and 11 are formed cam-shaped recesses 16. In these recesses 16 are arranged clutch rollers or balls 17, which when the gear-wheels 10 and 11 are turned in one direction will bind between the cam-surfaces 15 and the adjacent wall of the annular recess 12, thereby locking said gear-wheel to the sleeve 2 and causing said sleeve to be turned in the direction said gear wheels are turned. This movement is imparted to the shaft 1 through the clutch-sleeve 6, thereby driving said shaft in one direction.

On the sleeve 3 is loosely mounted a pair of spur gear- wheels 18 and 19, said wheels being provided with annular recesses 20. In the recess 20 of the wheel 18 is arranged a clutch-disk 21, and in the annular recess of the wheel 19 is arranged a clutch-disk 22. Said disks 21 and 22 are fixedly mounted upon the sleeve 3. The disks 21 and 22 are provided at equal distances apart around their peripheries with radially-disposed camsurfaces 23, between which and the adjacent annular wall of the recesses 20 are formed cam-shaped recesses 24, in which are disposed clutch rollers or balls 25.

In order to drive the gears 10 and 11 and 18 and 19, a rack-bar frame 26 is provided, said frame being preferably in the form of a yoke, as shown. On the upper plate or arm of the frame 26 are formed or arranged two series of rack- teeth 27 and 28, the rack-teeth 27 being engaged with the gear-wheel 11, while the rack-teeth 28 are engaged with the gear-wheel 19. On the lower plate or arm of the frame 26 are formed or arranged two series of rackteeth 29 and 30. The rack-teeth 29 are adapted to engage the teeth of the wheel 10, while the rack-teeth 30 are adapted to engage the teeth of the gearwheel 18.

The arrangement of the clutch devices in the two inner and the two outer gear-wheels is such as to cause said wheels to be automatically locked with the sleeves on which they are mounted when the rack-bar is moved in one direction and to play loosely around the same when said bar is moving in the opposite direction. The clutch arrangement of the pair of gear-wheels 10 and 11 is just the opposite of that of the gear- wheels 18 and 19 so that when the clutch-sleeve 6 is thrown into engagement with the sleeve of one of said pair of wheels the shaft 1 will be turned'in one direction and when said clutch-sleeve 6 is thrown into the sleeve of the other pair of wheels the shaft 1 will be turned in a reverse direction.

In order to reciprocate the rack-bar frame 26, the same is connected to a link 31, said link being connected by eccentric-rods 32 with eccentrics 34 and 35, which are fixedly mounted upon a drive-shaft 36. The link 31 is adapted to be shifted in the well-known manner to change the speed in which the rack-bar frame is moved, thus providing for a changeable speed mechanism which may be used to advantage in grinding and milling operations or for other purposes.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, 'is 4 1. In a device of the character described, the combination with a shaft, of sleeves loosely mounted thereon, an intermediate clutch to lock one or the other of said sleeves into enga ement with said shaft, pairs of gear-whee s loosely mounted on said sleeves, each of said gear-Wheels having formed in one side an annular recess, clutch-disks fixedly mounted on said sleeves, said disks having radially-disposed cam-surfaces to coact with the annular wall of the recess in said gears, a clutch-roller arranged on each of said cam-surfaces to engage said annular wall and lock said gear and sleeves together when turned in one direction, a rack-frame having racks to engage said gear-wheels, and a link mechanism whereby said rack-frame is reciprocated, substantially as described.

2. In a device of the character described, the combination with a shaft, of sleeves loosely mounted thereon an intermediate clutch to lock one or the other of said sleeves into engagement with said shaft, pairs of gear-wheels loosely mounted on said sleeves, cam-clutch devices to lock one pair of said wheels on said sleeve when said pair of wheels is turned in one direction and similar clutch devices to lock the other pair of gear-wheels when the same are turned in the opposite direction, a rack-frame, a plurality of racks arranged on saidframe to engage said gearwheels, a link connected to said rack-frame, a drive-shaft, oppositely-disposed eccentrics mounted on said shaft, and eccentric-rods connecting said eccentrics with said link, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. I

JOSEPH W. CRIST.
