Gear shifting mechanism AUTOMATIC SHIFTERS INCThis invention relates to power operated gear shifting mechanisms for motor vehicles. In the copending application of Henry W. Hey, Serial No. 1. October 1. 5, 1. 93. The valve mechanism is controlled by a suitably located manually operable handle and by the operation of the motor to provide a follow up action whereby the shifting movement takes place to a degree proportional to the degree of movement of the handle. A fluid pressure operated device is connected to be influenced by pressures in opposite ends of the. In my copending application Serial No. May 1. 3, 1. 93. 8, I have disclosed and claimed a gear shifting mechanism which embodies the principles of operation of the copending application of Henry W. Hey, referred to above, the mechanism being highly simplified by embodying the control valve mechanism in one 2. Moreover, the reaction device by means of which the manually operable handle is provided with feel is arranged between the shifting motor cylinder and the head thereof to be influenced by pres 2. Such arrangement eliminates the separate fluid pressure reaction device, and the mechanism as a whole is not only simplified, but is so materially reduced in size as to facilitate its installation in many motor vehicles, the space available for a shifting mechanism being quite limited in most vehicles. While the mechanism of my copending appli 4. This is due to the fact that space is even further limited in such vehicles because of the character of the engine mountings, the placing 5.

Moreover, motor vehicle manufacturers are becoming increasingly aware of the desirability of eliminating the conventional gear shift lever from the floorboards and to this end several vehicles are now equipped with manual gear shift levers mounted beneath and movable parallel to the planes of the steering wheels, and other motor vehicles embodying the same feature are now in the process of design and manufacture. While such manually shiftable mechanisms are highly desirable over the use of gear shift levers projecting upwardly from the floorboards, they are objectionable for other reasons. In the first place, more force for performing a shifting movement is necessary because of the additional resistances to the shifting operations introduced because of the mechanical connections such as links, levers, etc. Design and Fabrication of Hand Operated Gear. Manual Transmission Gear Shifting. A Review Paper on Development of Automatic Gear Shifting Mechanism. In manual gear shifting mechanism, the gear can be change with the help lever. A manual transmission. The locking mechanism for any individual gear consists of a collar. Note that this advantage applies equally to manualautomatic. Gsc Studio 1.19'>Gsc Studio 1.19. Moreover, the gear shift levers partake of a substantial movement and accordingly it is difficult to reach around the steering wheel a sufficient distance to perform the shift into second gear. An important object of the present invention is to provide a gear shifting mechanism wherein the advantages of my copending application referred to are embodied in a shifting motor and its control mechanism and wherein the shifting mechanism may be mounted adjacent to and supported with respect to the steering column instead of being arranged adjacent the gear set where insufficient space may be available. A further object is to provide a mechanism of this character wherein a follow up valve mechanism is provided for the shifting motor and wherein the motor, the valve mechanism and the manual control means for the latter are all compactly arranged in association with the steering column. A further object is to provide a novel combination of valve operating and controlling levers and associated parts with the steering column in a particularly efficient arrangement wherein a minimum amount of space is required for the parts. A further object is to provide a novel mechanism of this character which may be readily employedin connection with manual shifting mechanisms having operating handles arranged adja,cent the steering wheel and wherein the changeover from manual to power shifting may be very. A further object is to provide a shifting mechanism adapted to be connected into a manual shifting mechanism which includes a shifting crank projecting laterally from the steering column beneath the floorboards and wherein the motion transmitting means usually connected to such crank is eliminated in favor of a valve operating link forming a part of the present mechanism, such link being arranged. Other objects and advantages of the invention will become apparent during the course of the following description. Zip File For Pc. In the drawings I have shown two embodiments of the invention. In this showing Figure 1 is a perspective view of the mechanism associated with certain parts of a motor vehicle, the view being taken looking toward the rear of the vehicle, Figure 2 is a transverse sectional view taken at right angles to the steering column and looking toward the lower end thereof, the plane of section being approximately as indicated by the line 2 2 in Figure 1, Figure 3 is an axial sectional view through a portion of the steering column, parts being shown in section and parts being broken away. Figure 4 is a longitudinal sectional view through the shifting motor and associated parts, the plane of section being parallel to the axis of the motor and taken through the axis of the control valve, Figure 5 is a section on line 5 5 of Figure 4, Figure 6 is a section on line 6 6 of Figure 2, certain of the motor parts being shown in broken lines, Figure 7 is a fragmentary sectional view on line 7 7 of Figure 4, Figure 8 is a horizontal fragmentary sectional view taken approximately on the horizontal plane indicated by line 8 8 of Figure 1, showing a portion of the selecting means associated with the transmission, Figure 9 is a perspective view similar to Figure 1 showing a slightly modified form of the invention, and, Figure 1. Referring to Figure 1 the numeral 1. The vehicle is provided with a steering column indicated as a whole by the numeral 1. A motor vehicle engine and clutch not shown deliver power through a gear set indicated as a whole by the numeral 1. In Figure 8 a suitable mechanism is illustrated as being associated with the gear set for selecting either shift rail for actuation and for transmitting an actuating force thereto. This mechanism may be of any desired type and accordingly has not been illustrated in detail.

It will be apparent that since the sleeve 2. As stated, the structure shown in Figure 8 is not essential per se to the operation of the present invention since any desired type of selecting and shifting mechanism may be employed in conjunction with the gear set. The mechanism in Figure 8, however, is used in conjunction with the gear sets of certain motor vehicles which are provided with manually operable means for actuating the pin 3. In Figures 1 and 2 the steering column is shown as being of the general type employed with the manual shifting mechanism referred to. It will be noted that the steering column is formed of a pair of sections 3. These column sections are connected by a two part casting 3.
