To a/ZZ whmtt/nctyconcern@f p Y y Beit known";thatLENosJ-IJJOHNSON,.of Lagrange, ,county of,`Cook,iand1State'of I'Illinois, have inventedcertain new'and, useful' Improvements rV in ,A Means l for" Transmittin'g Power from Car-Axles,fofwhich the following is a specification.

This invention relates to means for transmitting power from car-axles, and is in the nature of an improvement upon my previous invention patented January 16, 1894, and numbered 513,046. 'f

The object of the presentinventipnfis to simplifyin important respects the mechanical construction and toca'rry out and embody in a practical and econdmicalfonm a -complete equipment 'for .tir-,aufsmittingi,4 the ,l power derived from the rotation of the 'car-axle to' a machine, such as a dynamo, mounted in proximity thereto, the construction being. such that the power-transmitting means and the power-using device-say adynamo or fanmay all be mounted beneath the body of the car and in such manner as not to partake of the oscillations of the car-body, being suspended on the truck and moving and turning therewith. v

I have shown my inventionas applied to a car-axle and connected ,fort-the, driving of a dynamo, the power-transmitting shaft being coupled to thefdynamo-shaft b'ymeans of a friction-clutch. i i

In the drawings, Figure 1 is a4 plan view showing the mechanismfappliedto the caraxle and the casing inclosingthe driven dynamo. Fig. 2 is a side elevation of the same, the car-axle and a part of the truck-timbers showing in section and the car-wheel indicated by dotted lines. Fig. 3 is a plan section through the sleeve around the axle, some of the gearing andthe clutch mechanism being also insection. Fig. 4l is a vertical section through the gear-casing, taken at right angles to the car-axle, alsoshown in section. Fig. 5is a side elevation of the gear-casing and a part lof the dynamo-casing', the former being in section to show particularly the parting of the gear -casing to enable it to be clamped around the axle. Fig. 6 is a longitudinal section of the gear-casing, showing a power-transmitting counter-shaft, a drivinggear, and clutch `mechanism mounted thereon. Fig. 7 is av side elevation of one ofthe bevel-gears having a clutch memberand Fig8is a perspective view of one shiftable i member `of the clutch.

In carrying out the invention the purpose Iis to so mount the power-transmitting means as thatit shall rock' or oscillate around the axle, and'in order to enable the application tothe axle 4without specially preparing the. latter or detaching it from its truck I employ a counter-shaft, through which the power is transmitted, said counter-shaft being ar- `ranged parallel tothe axle and contained within a gear-casing, which is'constructed to provide a lubricant-chamber, so that the gear- 'forward end with a casing to contain the driven or power-using device-say a dynamo. The gear-casing as well as the casing for the kdriven'.machine are so constructed that their parts may be separated to admit of quick application and detachment for the inspection or repair of any of the working parts.

In the drawings, 10 represents the car-axle, the dotted line 11`the car-wheel, and 12 the truck-frame. Inorder to obviate the necessity of turning down or otherwise specially treating the car-axle, I prefer `to mount thereon a sleeve V13, Fig. 3, which may be constructed in sections, as shown at 14, Fig. 5, and secured'to the axle by-set-screws 15, which are held by the locking-screws 16. The sleeve has cast thereon or secured thereto a gear 17 (see Fig. 3) and Vis preferably provided with circumferential grooves 18 to receive anges of the gear-casing. ,The latter is made preferably i'n'three sections 19 20 21, the upper section 19 being bolted to the sections 20 and 21, and when the latter is removed thegearcasing, with its contained gearing, .may be removed from or applied to the axle with all of its parts connected up, thus effecting not only economy and readiness of application to car-axles alreadyin service, but equal facility in removal for repairs or renewals. Within the gear-casing formed between the sections 19 2O is arranged a transmitting power-shaft 22, parallel to the axle and provided with a spur-gear 23, enmeshing kwith the gear 17,

whereby the rotary motion of the axle is transmitted to the counter-shaft. Loosely mounted on the latter are the bevel-gears 24 25, which are provided with clutch-jaws 2G on their inner faces, adapted to be engaged by the shifting clutch members 27 28. The latter are connected by the pins or bolts 29, whose heads are chambered within the clutch member 2S and threaded into the member 27, and the coiled springs 30, through which the pins pass,serve to keep the shifting members of the clutch in fixed relation to each other. The distance between the clutch-jaws 2G on the bevel-pinions 24 25 is such with relation to the position of the exterior faces or jaws of the connected clutch members 27 28 that when one of said clutch members is in driving engagement with the bevel-gear the other one is thrown out, and upon a reversal of direction of rotation of the axle the clutch will be shifted therebjT into driving engagement with the other pinion. A bevel-gear 3l is enmeshed with both of the bevel-pinions 24 25 and is mounted upon a stub-shaft 32, having a bearing in a forward extension of the gear-casing formed by the members 19 20. Said stub-shaft has a collar 33, which maintains its position by fitting within a bearing formed within the gearcasing,and it being understood that the entire bearingis babbitted or otherwise constructed to maintain the shaft in proper aliuement and position. The forward end of the stub-shaft 32 has a friction clutch ring or sleeve 34 keyed thereto, and frictionshoes 35 are applied to said sleeve or ring by the sliding of the clutch-hub 36 and the toggle-links 37 38. The clutch-hub 36 is keyed or splined on the sleeve 39 and the latterin turn is keyed to the shaft 40, which may be the armatu re-shaft of a dynamo, the position of which is indicated by the dotted linesin Fig. 2. The driven or power-using machine is preferably mounted in a casing the major portion of which may be continuous of or integral with the gear-casing sections 19 20. Preferably, however, the forward ends of said sections are beveled, and a cap 4l, which may be of sheet metal, is applied over the dynamo or other machine, suitable provision being made to secure dust-proof joints, and this cap 4l may be held upon the casing by means of the bail 42, having a perforation registering with the perforation in the lug 43, and the two may be securedtogether-as,forexample,by means of the hasp of a padlock. The lug 43 has the inclined cream surface 44, by means of which the cap4l can be tightly drawn t0 its seat to make adust-proofjoint. The forward end of the casing and the driven machine may be suspended from the truck by means of a hanger or stirrup 45, the cross-bar of which is perforated, as shown at 46, for the passage of apin 47, to which are applied cushion-springs 4S 49.

It will be understood that some changes in the details of construction may be iliade while preserving the general features and utilities of my invention. For example, I have shown masse a sleeve applied to the axle and prefer to use such a sleeve, because it avoids any necessity of turning or finishing the axle to receive the` gearcase,which must be connected to the axle by a practically dust-proof joint and also in such manner that a body of lubricant may be supplied for the gearing if tooth-gears be used. The sleeve also strengthens the axle instead of weakening it. While I have shown and described tooth-gears,friction-gears maybe employed and the form of the clutch mechanism may, of course, be varied. I have also shown and described a power-transmitting shaft arranged at right angles to the counter-shaft; but obviously the driven shaft of the powerusing machine maybe connected directly with the gearing, although in such construction the sudden shocks and jars produced in the starting and stopping of the axle suddenly would be injurious and undesirable.

Among the principal advantages secured in the above-described device are the following: The gearing and the power-using machine are inclosed in a tight or dust-proof casing and the whole is so mounted that it is not affected by the vibrations of the car-body or of the truck itself. The entire apparatus is self-contained-that is,it is mounted within a single support or casing, which is flexibly connected to the truck-frame and is also adapted to vibrate or rock upon the axle. The apparatus, by reason of the use of a parted or sectional casing, can be applied or removed without detaching the axle from the truck and all parts of the apparatus are readily accessible for inspection or repair. It is also obvious that by making the casing sectional, as described, the gearing and the power-driven machine can be removed without disconnecting them, leaving the gear or the gear and sleeve, as the case may be, secured to the axle. The construction of course enables the assembling of all of the parts at the place of manufacture, while the device may be applied to the axle by unskilled labor.

l. A means for transmitting power from car-axles, comprising a gear mounted upon the axle, a counter-shaft arranged parallel to the axle, a gear-casing adapted to be clamped about the car-axle to inclose the gear thereon and the counter-shaft, gearing arranged within said casin g and connected to the countershaft and clutch mechanism whereby rotary motion of the car-axle in either direction may be transmitted through said gearing in the same direction to a power-using device, substantially' as described.

2. In means for transmitting power from car-axles, the combination with a gear mounted upon the axle, a counter-shaft, a gear fixed thereon and enmeshed with the axle-gear, gear-wheels loosely mounted upon the counter-shaft, a power-transmitting shaft geared with said loose gears, and clutch mechanism whereby either of the loose gears may be made fast with the counter-shaft whereby rotary IOO IIO

Amotion in the same direction may be impart'- ed to the power-transmitting shaft when the axle and counter-shaft are rotated in either direction, substantially as described.

3. In means for transmitting power from car-axles, the combination with the axle of a cured to turn with the counter-shaft, substantially as described.
