MlTER-G EAR CASE.

SPECIFICATION forming part of Letters Patent No. 744,310, dated November 17, 1903.

Original application filed May 16, 1901, Serial No. 60,543. Divided and this application filed February 24, 1902. Serial 1110.95399- (No model.)

To all whom it may concern.-

Be it known that I, HARRY DE WALLACE, of Watertown, Jefferson county, New York, have invented certain new and useful Improvements in Miter-Gear Cases, of which the following is a specification.

This invention relates to improvements in miter-gear cases designed particularly for use in connection With train-order signals and train-stopping devices of the class described and claimed in Letters Patent heretofore issued to me and numbered and dated as follows: No. 617,232, dated January 3, 1899; No. 623,503, dated April 18, 1899; No. 642,303, dated January 30, 1900; No. 657,592, dated September 11, 1900, and also in my pending application for Letters Patent, filed May 16,

1901, Serial No. 60,543, of which this application is a division.

My present invention is designed to provide a simple and inexpensive miter-gear case that may be used between the truck of the locomotive and the train-order signal for the purpose of permitting a ready connection to be made between the shafts extending from said truck to said train-order signal.

Theinvention consists generally in a mitergea'r casing formed in two parts held together by suitable screws or other means and forming bearings for the shafts by which the miter-gears are carried.

The invention consists, further, in the constructions and combinations hereinafter described, and particularly pointed out in claims.

In the accompanying drawings, forming part of this specification, Figurel is a side elevation of a locomotive having applied thereto a miter-gear case embodying my invention. Fig. 2 is a vertical section through the gearcase. Fig. 3 is a horizontal section on line X X of Fig. 2.

In the drawings, 2' represents a substantially spherical miter-gear casing, preferably made in two parts, provided with the lugs 3, said parts being adapted to be secured together by the bolts 4. Forming the case in two parts, as shown, permits it to be separated on the line X X. Each half of the case is provided with half boxes or bearings for the shaft 5 and one-half of the case is provided with a'bearing for the shaft 6, arranged at right angles to the shaft 5. The shaft 5 is preferablya short sha'ft extending a short distance outside of the casing and provided with a miter-gear 7, arranged within said casing. The shaft 6 is also provided with a miter-gear 8, arranged within said casing and meshing with the gear 7. The shaft 5. is provided outside of the casing with a collar 9, secured thereto by a suitable pin 10, and at its other end it enters a coupling-sleeve 11, to which it is secured by a pin 12. The sleeve 11 is also adapted to receive the shaft 13, that extends forward, preferably along the runningboard of the locomotive, and is connected by suitable means to the axle of the locomotive.

The gear-casing is provided with the opening 14:, adapted to be closed by a suitable cover 15. Through this opening oil may be applied to the miter-gears. The sleeve 11 is preferably provided with a slot 16, and a pin may be arranged in this slot to connect with the shaft 13. This slot allows some lengthwise movement to the shaft 13. The vertical shaft 6 is preferably held in position by a suitable collar 17. The casing is so constructed that the oil may at least half fill the case, and the gear 7 will pick it up and carry it to all the bearings. The practical application of the miter-gear casing and its connections is shown in Fig. 1. The casing may be placed either above or below the running-board and in either position will serve its purpose equally well.

While I have shown the miter-gear case applied to the connection between the locomotive-axle and the train-order signal, I do not wish to be limited to its use in connection with any particular device, as the same may be used in many other connections with equal advantage.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the train-order signal and the locomotive-axle, of the shafts 6 and 13, arranged at right angles to each other and provided with the miter-gears 7 and 8, and the casing 2 forming'bearings for and the sole connection between said shafts and surrounding and inclosing said miter-gears.

2. The combination, with the shafts arranged at right angles to each other, and provided with miter-gears meshing with each other,of the oil-tight casing, forming bearin gs for and the soleconnection between said shafts and surrounding and inclosing, said mitergears and forming an oil-pocket for said gears.

3. The combination, with the substantially spherical casing provided with bearings at right angles to each other, of the short shaft 5 mounted in said casing and projecting therefrom, the sleeve 16 secured upon said shaft 5,

1 the shaft 6 also mounted in said casing and the miter-gears 7 and 8 arranged upon the shafts 5 and 6 within said casing and meshing with each other.

In testimony whereof I have hereunto set my hand this 14th day of February, 1902.
