Description

w. uomowt CHANGE SPEED DEVICE.

APPLICATGON FILED APR. II. 1912.

1,318,733. Patented Oct. 14; 1919.

. INVENTOR VW/fr/d Dar/on ,4 Mat WILFRID DORION, OF CHARLESBOURG, QUEBEC, CANADA.

CHANGE-SPEED DEVICE.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed April 11, 1918. Serial No. 227,939.

To all whom it may concern:

Be it known that I, WILFRID DORION, residing at Gros Pin, Charlesbourg, in the .trovince of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Change-Speed Devices; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to improvements in change-speed devices for driving pulleys, and is here shown as applied to a motor eye e.

The invention consists particularly of two members or pulleys of different diameter, the larger one being adapted to fit over the pulley of smaller diameter and so enlarge its diameter, thereby reducing the speed.

The object of the invention is to provide a simple, eilicient and comparatively inexpensive device of the character above indicated.

The invention will hereinafter be fully explained in the following description, and

its preferred embodiment is illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of the invention here shown as ap lied to a motor cycle.

Fig. 2 is an enlarged front elevation of the invention and its operating mechanism, disclosin portions of the motor and of the top bar ot t e frame of the motor cycle.

Fig. 3 is an enlarged side elevation of the invention.

Fig. 4 is a side elevation of the driving pulley.

Fig. 5 is a front elevation of Fig. 4.

Fig. 6 is a side elevation of the large diameter pulley.

Fig. 7 is a front elevation of Fig. 6.

Like numerals of reference indicate corres onding parts in each figure.

n the drawings, 1 is the cycle, 2 the motor and 3 the crank shaft. On the end of said crank shaft 3 is rigidly mounted the pulley 4 which is provided with the side flanges or guides 5 and 6 having the inclined sides 7; and 8 are slots or openlngs 1n which the larger diameter pulley 9 slides.

The pulley 9 has a drum-like shape, and 10 are lateral slots provided therein which divide periphery into separate, transversely-dispose sections or tongues; 11 are oblique lugs which project radially from the free edges of said pulley sections or tongues and extend toward the axis of the pulley which are adapted to slide and support the pulley 9 over the pulley 4. The arrangement of the aforesaid pulley sections or tongues and their lugs 11 correspond to that of the slots 8 in pulley 4, so that the pulley 9 will fit within the pulley 4 as disclosed in dotted lines in Fig. 2. The outer end of the hub end of said pulley 9 is provided with a circular groove 12 in which fits the sleeve 13, and 14 is a forked rod pivotally engaging said sleeve. v

A bracket 15 is secured on said motor 2 and projects outward, and on its outer end the bell-crank lever 14 is ivotally secured thereto. 011 the end of 110 upper arm of said lever His pivotally secured the link 16, and 17 is a hand lever pivoted at 18 to the frame of the cycle, or in some other manner if preferred, and pivotally secured at its outer end to the lit. k 16. On the frame of the cycle is provided a bracket 19 suitably notched to lock the said lever in one or the other position.

A belt-tightening lever 20 of bell-crank form is suitably pivoted adjacent the lower end of its vertical arm to the frame of the cycle, and 22 is a toothed rack adapted to engage the said vertical arm of said lever and lock it in position; and on the free rear end of the lower or horizontal arm of said lever is mounted the roller 23 which is adapted to take up the slack in the belt 24 which engages the driving pulle 4 and the pulley 25 secured to the rear w eel of the cycle.

It will readily be seen that in the operation of the device, if the hand lever 17 1s pulled from left to right, the belLcrank lever 14 will be actuated and will push the pulley 9 into the position shown in dotted lines in engaged from the pulley 4, thus reducing its diameter. The slack which will occur in Y the belt 24 will be taken up by the lever 20,

by ushing it downwardly.

t is evldent from the foregoing description that any. other suitable means of operating the pulley 9, may be used without departing from the scope. and field of the invention as hereinafter claimed.

What I claim as my invention is:

l. A device of the character described, comprising a shaft; a flanged driving pulley mounted thereon and having oppositely-located guide slots formed through its flanges; a pulley of larger diameter, slidably mounted on said shaft adjacent said driving pulley and provided with lugs registering with the slots in said drivin pulley; and means to slide the pulley of la the driving pulley so as to cause said lugs to pass through said guide slots and said pulley of larger diameter to fit over said driving pulley and thereby enlarge its diameter; substantially as described.

2. A device of the character described, comprising a shaft; a flanged driving pulley mounted thereon and having a plurality of oppositely-located guide slots formed through its flanges; a pulley of larger diameter slidably mounted on said shaft adjacent rger diameter toward I said driving pulley and having its peripheral wall split into a plurality of spaced, transverse sections or tongues which are provided on their free edges with inclined lugs, said sections or tongues and their lugs registering with the slots in said drivin pulley; a member for shifting one of sai pulleys toward the other so as to cause said lugs and pulley sections or tongues to ass through said guide slots, and said sections or tongues to surround said driving pulley and thereby enlarge its diameter, said shifting member being connected at one end to the pulley to be shifted; and an operating member for said shifting member connected to the other end thereof; substantially as described.

Signed at Quebec, Canada, this 16th day of October, 1917.

WILFRID DORION.
