CHANGE-(BEARING.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed May 10, 1904-.- Serial No. 207,266.

To (all whom it may concern:

Be it known that l, J OSEPH S. lVTORELAND, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Change-Gearing, of which the following is a specification.

My invention relates to a change-gearing or controlling device; and it consists in the parts, constructions, and combinations herein described and claimed.

The objects of my invention are to provide an improved controlling device especially adapted for use with motor-vehicles in which the speed can conveniently be controlled with certainty by a single operating part.

A further object of my invention is to pro vide a controlling device in which the several parts are actuated by a common operatinglever constructed for movement in a single plane, thereby avoiding the well-recognized defects inherent in existing controlling devices in which the operating element is constructed for movement in several different planes.

A further object of my invention is to provide a controlling device constructed to release the clutches before shifting the gears, thus preventing injurious shock to the gears and permitting the resistance to be thrown thereon gradually.

A further object of my invention is to pro vide a simple and compact controlling device in which the clutches are normally maintained in released position, whereby danger of accidentally starting the motor-vehicle is minimized.

1n the accompanying drawings, constituting a part of this application, and in which similar reference-symbols indicate corresponding parts in the several views, Figure 1 is a seetional view on a plane indicated by the line 1 1 of Fig. 2, illustrating one embodiment of my invention. Fig. 2 is a sectional view on a plane indicated by the line 2 2 of Fig. 1. Fig. 3 is a detail sectional view illustrating a modified construction. Fig. 4 is a front end elevation of the construction shown in Fig. 1. Fig. 5 is a sectional elevation on a plane indicated by the line 5 5 of Fig. Fig. 6 is a fragmentary perspective view, on an enlarged scale, illustrating a portion of a stationary sector and its cooperating parts. Fig. 7 is a fragmentary perspective view, on an enlarged scale, illustrating a portion of an adjustable sector, together with the cooperative parts of an operating-lever; and Fig. 8 is a fragmentary perspective view of the adjustable sector, showing means for looking it in its several adjusted positions.

Referring to the drawings, 1 indicates a gear-casing, shown in two parts secured together by bolts 2 passing through flanges 3 thereon. A main shaft 4 is shown journaled at 6 in the casing and rotatively mounted in a sleeve 7, which latter is journaled in the casing at 8. The sleeve 7 carries two gears 28 29, a s iiroeket-wheel 32, and one member of a clutch device comprising a drum 12, in which aplurality of rings 87 are splined for axial movement. The other member of the clutch comprises a pluralityof disks 85, which are splined on the main shaft i to permit axial movement thereon, the several rings and disks being alternately arranged and pro vided with suitably-engaging surfaces. Levers 83, shown pivotally supported on a collar 82, secured to the main shaft l, are connected by links 84 to the contiguousdisk 85. A cone 14 is shown loosely mounted on the shaft 4 in position to be moved into or out of engagement with the free ends of said levers 83.

Fig. 3 illustrates an alternative construction,in which the transmission sprocket-wheel 32 is replaced by a power-transmission shaft 33, suitably journaled at 33 in the gear-casing and carrying a bevel-pinion 34, driven by a suitable gear 35 on the sleeve 7.

Agear-wheel 26 is secured to the main shaft 4, in mesh with a gear-wheel 27, secured to a secondary or counter shaft 5. The shaft 5 is shown journaled at 9 in the casing 1 and rotatively mounted in a sleeve 10, which latter is journaled in the casing at 11. An adjustable gear 36 is splined on the sleeve 10 in position to permit its being thrown in mesh with the gear 29 or with a pinion 30, which is journaled in the casing in mesh with the gear 28. The sleeve 10 carries one member of a clutch device comprising a drum 12, in which a plurality of rings 87 are splined for axial movement. The other member of the clutch comprises a plurality of disks 85, splined on the shaft 5, said rings and disks being alternately arranged and provided with suitable engaging surfaces. Acone 15 is shown loosely mounted on the shaft 5 in position to be moved into or out of engagement with levers 83, which are pivotally supported on a collar 82 secured to the shaft 5, said levers being connected by links 84* to the contiguous disk 85 A clutch-lever 22 is secured to a suitablyjournaled spindle 23 and is provided with yokes which engage pins 19, extending from straps 16, suitably fitted on the respective cones l4 and 15. A crank 24:, secured to the spindle 23, is connected by a rod 25 to a crank 62, rotatively supported on a shaft 47, which latter is suitably journaled in bearings 48 and 418*.

An adjustable quadrant 63 is secured to the crank 62 by arms 63. The inner arc of said quadrant is provided with a plurality of beveled notches 77, 78, and 79, arranged to be engaged by a resilient or spring stop 76, constructed to engage said notches for locking the quadrant in its several adjusted positions. The spring stop is formed of sufficient strength to prevent accidental shifting of the quadrant, but is preferably constructed to permit its being forced out of engagement with the notches by the tapered walls of the latter upon actuation of the quadrant 63.

A shaft 41, journaled in the gear-casing, carries a crank 40, which is connected by a rod 38 to a crank 50, secured on the shaft 47.

A yoke 43, secured to the shaft 41, engages pins 4 1 on a strap 45, suitably fitted in an annular groove 16 in the hub of the gear 36.

An arm 51, secured on the shaft 4:7, is provided with guides 55 and 56 for an adjustable latch-bar 52. A spring 60, confined between the guide 56 and a collar 61 on the latch-bar, tends to maintain said bar in its normal outer or upper position. The bar 52 carries a latch 54, arranged to be brought into engagement with a series of notches 57, 58, and 59 in a stationary sector L9 or with a notch 81 in a block 80, carried by an operating-lever 64:, which latter is rotatively mounted on the shaft 47. a

An actuating-rod 65 is slidably mounted in the lever 64, a spring 71 being provided for normally maintaining said rod in its outer or upper position. The actuating-rod is provided with a shoulder 69, constructed to engage the lever 64: for limiting the outward or upper movement of said rod, and with a shoulder 68, constructed to engage a lip 53 on the latch-bar 52 for shifting said bar to its inner or lower position upon depression of the actuating-rod. The rod 65 is bent at 66 to avoid interference with the shaft 47 and is provided at its lower portion with a latch 7 4, arranged to be shifted into engagement with a recess 75 between two shoulders 7 5 extend ing from the outer arc of the adjustable sector 63, as shown especially in Figs. 7 and 8. The shoulders 75 are shown provided with inclined outer ends for permitting thelower latch 74 to ride up on them upon actuation of the operating-lever.

From the above description it Will be understood that my invention provides an improved construction in which an operatinglever constructed for movement in a single plane is adapted to control the clutches 87 and 85 87 or to shift the adjustable gear 36.

The parts are preferably so constructed and proportioned that the lower latch 74 of the actuating-rod 65 will be disengaged from the notch 75 upon a depression of said actuatingrod sufficient'to shift the latch 54 into engagement with the notch 81, thus permitting the gear-shifting and clutch-controlling mechanisms to be independently actuated during the various adjustments of the change-gearing.
