SPECIFICATION forming part of Letters Patent No. 779,846, dated January 10, 1905.
Application filed July 26,1904. Serial No. 218,254.
T 0 a whom, it may concern.-
Be it known that I, OSCAR LEE HANEY, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented new and useful Improvements in Gears, of which the following is a specification.
This invention relates to transmission mechanism.
The objects of the invention are to improve and simplify the construction of such mechanism; furthermore, to increase its efficiency in operation.
With the foregoing objects in view the invention resides in a stationary shaft, upon which is mounted a driving element and a driven element, each of the elements having gear-teeth thereon and a set of gear-wheels and the shaft having thereon an adjustable gear-sleeve adapted to be thrown into and out of gear with either or both sets of gear-wheels or to be locked against movement on the shaft, whereby three different speeds may be given to the driven element.
The invention also resides in the particular combination and arrangement of parts and in the precise details of construction hereinafter described and claimed as a practical embodiment of the invention.
In the accompanying drawings, forming part of this specification, Figure 1 isa longitudinal section, partly in elevation, of a transmission-gear constructed in accordance with the invention. Fig. 2 is a section on line 2 2, Fig. 1, looking from the right. Fig. 3 is a similar section on the line 3 3, Fig. 1, looking from the left. Fig. i is a longitudinal section showing in detail the stationary shaft and the gear-sleeve mounted thereon. Fig. 5 is a detail view showing the manner of attaching the annular gear element to the driven element.
- Like referencenumerals indicate corresponding parts in the difl erent views.
Briefly outlined, the improved mechanism comprises a driving element A, a driven element B, and a stationary shaft C.
Although the mechanism of this invention is adapted for use in various connections, it
5 has been illustrated in the drawings as adapted for application to an automobile. In this use 'of the invention the gear-wheel 1 of the driving element A is intermeshed in any suitable manner with the engine or motor of the automobile, and the sprocket-wheel 2 of the driven element B is connected, by means of a suitable sprocket-chain, with the axle of the vehicle. Thestationary shaft C is mounted in any suitable Inanner within brackets, such as 3, said Shaft being held stationary in said brackets by means of screws 4. Rigidly mounted upon the shaft C in any suitable manner, as by means of screw-threads, is a disk 5, which is beveled on one edge, as shown at 6, and formed with an annular flange 7 to produce an annular guideway for a series of antifriction-balls 8. The driving element A comprises a hub 9, which fits over the annular flange 7 of the disk 5 and rotates upon the annular series of balls 8. The gear-wheel 1 of the driving element A is preferably screwed upon the hub 9 and is held in place by means of a suitable lock-nut 10, which in the embodiment shown consists of a screw-threaded ring the threads of whichextend in a direction opposite to the threads of the gear-wheel 1. The hub 9 is formed with a tubular extension 11 and a tubular extension 12, the tubular extension 12 being concentrically larger than the extension 11 and being extended beyond the said extension, as shown. An annular set of gearwheels 13 is fastened upon the hub 9, preferably by means of journals let screwed into said hub, the gear-wheels 13 being held upon their journals 14, by means of an annular ring 15, retained in place by means of screws 16, extending into the ends of said journals.
It will be observed from Fig. 3 that the tubular extension 11 of the hub 9 is cut away, as shown at 17, adjacent to each of the gearwheels 14:, whereby said gear-wheels are permitted to project outwardly beyond said tubular extension 11 and intermesh with an annular gear element 18, which is rigidly connected with a tubular extension 19 of the driven element B. The preferred manner of rigidly connecting the gear element 18 with the tubular extension 19 of the driven element is illustrated in Fig. 5 and comprises a dovetail connection formed by providing notches 20 in the ends of the tubular extension and segmental flanges 21 on the gear element 18 to engage said notches, whereby the rotation of the gear element 18 causes the rotation of the driven element B, as will be described more clearly hereinafter.
The tubular extension 12 of the hub 9 is provided internally with cogs or teeth, whereby it forms a gear element, which is intermeshed with an annular set of gear-wheels 22, fastened on the driven element B in any suitable manner, as by means of journals 23, screwed at their ends into said driven element B, a suitable annular ring 24 being fastened to the journals 23 by screws, such as 25, in order to hold the gear-wheels securely upon their journals.
Mounted upon the shaft C is a longitudinally-adjustable sleeve 26, which is formed on its periphery with cogs or teeth 27, which are adapted when in the position shown by Fig. 1 to mesh with the inner periphery of both annular sets of gear-wheels 13 and 22 upon the driving element and driven element, respectively. The gear-sleeve 26 is also adapted when moved longitudinally in one direction to be disengaged from the gear-wheels 22 and engaged only with the gear-wheels 13 and when moved in the opposite direction to be engaged with the gear-wheel 22 and disengaged from the gear-wheels 13. The sleeve 26 is formed interiorly with an annular portion 29, which fits closely around the shaft C, said annular portion 29 being formed with spline-grooves 30, adapted to receive lugs 31 on the shaft C when moved in one direction and to receive lugs 32 on said shaft when moved in the opposite direction. In order to facilitate its longitudinal adjustment, the sleeve 26, as shown in Fig. 4, is swiveled upon a sleeve 33, which is formed with an annular flange 34, fitted into a tubular extension 35 on the sleeve 26 and held therein by means of a screw-threaded ring 36. Upon the sleeve 33 is a collar 37, against which bears one end of a coil-spring 38, the other end of which bears against a disk 39, screwed upon the shaft C in a manner similar to the disk 5. Secured to the sleeve 33 by means of rivets, such as 40, are the parallel ends of a stirrup-band 41, which parallel ends extend along suitable longitudinal grooves 42 in the shaft 0. The stirrup-band 41 is engaged by any suitable lever, such as 43, by means of which the sleeve 33 may be drawn longitudinally in one direction upon the shaft (1, the spring 38 serving to force said sleeve in the opposite direction.
The driven element B is formed with a tubular extension 43, having thereon an annu lar collar 44, which holds in place a set of antifriction-balls 45, rotating upon the disk 39.
In order to permit the driven element B to rotate without friction independently of the driving element A, a ring 46, having an angular flange 47, fitting over the annular gear element 18, is screwed upon the hub 9, a series of antifriction-balls 48 being interposed between said ring'46 and the annular gear elements 18 of the driven element B.
From the foregoing description it will be apparent that the improved mechanism of this invention permits three different speeds to be given to the driven element. This is accomplished by moving the gear-sleeve longitudinally in one direction or the other or into its intermediate position.
In its combination and arrangement of parts and in its details of construction the mechanism of this invention presents an improvement over prior mechanism for a similar purpose.
Having thus described the invention, what is claimed as new is 1. A transmission mechanism comprising a stationary shaft, a driving element thereon, a gear element upon the driving element, a set of gear-wheels on the driving element, a driven element, a gear element on the driven element, intermeshed with the gear-wheels on the driving element, gear-wheels on the driven element intermeshed with the gear element on the driving element and a gear-sleeve on the shaft, adapted to be thrown into engagement with both sets of gear-wheels on the driving and driven elements or to be thrown out of engagement with one set of gear-wheels and to be simultaneously locked against rotary movement on the shaft.
2. A transmission mechanism comprising a driving element having a hub formed with a plurality of tubular extensions, one of said extensions forming a gear element, an annu lar set of gear-wheels on the hub, each of said gear-wheels projecting through a cut-away portion in the smaller of the tubular extensions, a driven element having a'gear element intermeshed with the gear-wheels of the driving element, an annular set of gear-wheels on the driven element, intermeshed with the gear element of the driving element, a gear-sleeve having spline-grooves and a shaft supporting the driving and driven elements and the gearsleeve, and having lugs adapted to be engaged to the grooves of said gear-sleeve.
