GEORGE CURTIS CANNON, OF NE YORK, N. Y.
AUTOMOBILE DRIVING-GEAR.
SPEGIFICATIONforming part of Letters Patent No. 775,233, dated November 15, 1904.
Application filed November 5, 1903. Serial No. 179,934. .No model.)
in the county and State of New York, have inl i i vented a new and Improved Automobile Driv- I a rearward extension v, to which is bolted a ing-Gear, of which the following is a full,clear, and exact description.
This invention-relates to the differential gear and appurtenant parts of a motor-vehicle.
According to my present invention the differential gear is located directly in the crankcase of the engine and driven by a direct connection with the crank-shaft. The divided transmitting-shaft passes from the differential gear and is joined by Cardan or equivalent flexible connections with short shafts mounted, respectively, in the sides of the vehicleframe, which shafts in turn have suitable connections with the driving-wheels. In this manner a more compact and reliable structure is produced, and owing to the peculiar arrangement of the shaft-sections and cardans the unavoidable working of the vehicle- 'frame in no way affects the easy movement of the driving parts.
This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.
Reference is to he had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cate correspoding parts in all the views.
Figure l is a plan view of the invention. Fig. 2 is an enlarged horizontal section of the crank-case and differential gear. Fig. 3 is a still further enlargement of the differentialgear ease and the driving-gear of the crankshaft, and Fig. at is a sectional elevation on the line 4: a of Fig. 3. i
The engine here illustrated is a four-cylinder poppet-valve engine and is described and claimed in my copending application for engines, filed of even date herewith, Serial No. 179,933. Obviously, however, this is not essential to the present invention.
The engine lies horizontally, as illustrated in Fig. 1, and is secured firmly to two crossbars a, joined to the side rails & and forming with said rails parts of the vehicle-frame. 0 indicates the forward section of the crankcase, and (Z the rear section, which are bolted together in the usual manner. 0 indicates the cylinders, which are directly joined to the crank-case section a. The rear section (Z has cap f, these parts a and f forming the inclosure for the differential gear.
The crank-shaft is formed in two sections 1, and, as best shown in Fig. 2, each section is formed with a flange g7, these flanges lying opposite to each other and having cavities 5 formed in their adjacent or inner faces. In said cavities are set gibs it, and the gibs also sit in corresponding cavities 2 formed in the web of a spur-gear 1', which gear lies between the flanges 1/ and is centrally orificed to receive the contiguous ends of the sections 1] of the crank-shaft. Bolts Z' are passed transversely through the flanges r and gear 27, and
'in this manner the two sections of the crankshaft and the gear i are firmly connected together to turn as one integral part.
1 indicates the two sections of the differential-gear case, these sections being essentially s'emispherical and being connected rigidly together by transverse bolts m, which pass through the flanges of the sections Z. Lying between said flanges and encircling the contiguous edges of the case-sections Z is an annulus w, peripherally toothed to form a spurgear and notched for the reception of the bolts m, as shown in Fig. 4:. In this manner the sections of the dilferential-gear case and the gear-ring 11 are rigidly connected together to turn as one integral part. Said gear-case sections have tubular extensions 1, which are suitably mounted in boxes f", formed on the protuberance w and cap j, as shown best in Fig. 2.
0 indicates the two sections of the driveshaft. These sections are revolubly mounted within the tubular extensions Z of the differential-gear case and respectively carry within said case the beveled gears p. \Vith these gears mesh the bevel-pinions and said pin ions are freely mounted on radial studs '1', projecting from an annulus 1', which encircles the contiguous ends of the shaft-sections 0. The said studs 7 project between the contiguous edges of the sections Z and have squared ends secured in corresponding cavities formed in the inner periphery of the gear-ring w, as best shown in Fig. 4. In this manner the shaft-sections 0 are driven uniformly from the crank-shaft g and said shaft-sections 0 are allowed that differential movement essential in motor-vehicles, as will be understood. If necessary, some additional support rigid with the engine may be provided for the outer portions of the sh aft-sections 0; but this is not essential.
The shaft-sections 0 project oppositely to the respective sides of the frame and have Cardan connections .9 with short shafts t, mounted in suitable boxes 6', carried by the side rails Z) of the frame. Said shafts t are connected to the vehicle driving-wheels (not shown) either directly or by a suitable gear '26. In this manner the shaft-sections 0 are mounted securely in and move with the engine; but at the same time the shafts t are revolubly driven, and through the cardans a any working of the frame intending to throw the shaftsections 0 and the shafts t out of alinement is prevented from interfering with the evenness and efliciency of the drive.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
