INCLOSING CASING FOR THE DRIVING-GEAR 0F CAR4DYNAMOS.

SPECIFICATION forming part of Letters Patent N 0. 741,971, dated October 20, 1903.

Application filed April 27, 1903.

1'0 aZZ whom it may concern..-

Be it known that I, PATRICK KENNEDY, a. citizen of the United States, residing in the borough'of Brooklyn, in the county of Kings and city and State of New York, have invented certain new and useful Improvements in Inclosing Casings for the Driving-Gears of Car-Dynamos, of which the following is'a specification. V a

This invention relates to means for lightingcars by electricity derived from dynamos driven from the axles of the cars.

In the United States Patent No. 685,516, granted October 29, 1901, on my application is shown a dynamo pivotally mounted on the truck-frame of a car and driven from the caraxle bya belt and pulleys, one of the latter being on the car-axle and the other on the armature-arbor of the dynamo. The dynamo is, as stated, pivotally mounted on the truckframe and a spring device is employed to so rock the dynamo on its pivot as to keep the driving belt taut and take up any slack therein.

The object of the present invention is to provide a means for excluding snow, dust, and the like from the pulleys and belt by which the dynamo is driven, so as to preserve the same from undue deterioration and wear. This is a matter rendered the more difficult from the fact thatin running,the truck-frame of the car has aconstant vibrating movement with respect to the axle thereof, and the arbor of the dynamo has also a movement toward and from the car-axle. It is also necessary to provide means whereby access may be had at all times to the belt and pulleys for inspection. As it is not possible byany known means to wholly exclude the entrance of snow and dust (one or both) to a-protecting-casing about the axle of the car, means are provided 7 herein for expelling or exhausting such snow or dust while-the car is in motion.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a side elevation of the protecting-casing as seen from the lower side in Fig. 2 Fig. 2 is a horizontal section taken'substantially along the line 00 in Fig.1. In this view the cured to the upper section.

Serial No. 154,398. (No model.)

belt and pulleys are represented in plan and only the casing 'in section. Fig. 3 is a vertical section taken substantially at 'line m in Fig. 2. Fig. 4 is a transverse section at line w in Fig. 1. Fig. 5 is a view of thecast-iron connecting-frame detached.

In the drawings it hasnot been deemed necessary to show the entire truck-frame of the car, the carwheels, and the dynamo. All

that has been shown aside from the protecting device are the car-axle a, the arbor b of the dynamo, the transverse truck-beam c, a transverse supporting-bar d of the truckframe, the pulley e on the axle, the pulleyf on the arbor of the dynamo, and the belt g on said pulleys. These will sulfice to illustrate the application of the invention in use.

Theprotecting-casing is of sheet metal stiffened with angle-iron, and it comprises two sections or parts A and B, which are connected by a frame 0, which may be of cast-iron. This frame is shown detached in Fig. 5 and is of rectangular form, with flanges on its faces to enter and form supports for the sheet metal of the casing. The frame is provided with flanges 72., whereby it is supported on and secured to the truck-beam c. The larger section A of the casing houses the pulley e and 'is in two parts, the lower portion 2 being removable, while the upper portion 1 is fixed.

This upper portion has a bracket 15, whereby it is supported at one end on the transverse bar 01, while at the other end it is carried on the truck-beam 0 through the frame O, to which it is secured. The lower section 2 is fitted up to the upper section, the line of junction being covered by a strip or platej, se-

This removable section 2 is secured at its deeper end to the pendent angle-irons 70, Fig. 2, by screws m, and at its other end it is secured to the frame O by screws 'n. It may have handles 0 for holding it when removed. The oar-axle a passes through the section A at the line of junction of the parts 1 and 2, and where it passes through the sides of the casing the latter is provided with dust-guards,of leather or the like. Each of these dust-guards consists of two like or similar parts 19, which are of somewhat conical,or rather semiconical,form. The upper one of these parts p is secured to the upper part 1 of the section A and the other to the lower part 2 thereof, and their edges overlap, as clearly shown in Fig. 1. The dustguard does not fit snugly about the axle, but is of such size as to allow the casing to move up and down without putting the leather into rubbing contact with the axle, which would soon wear it away. These guards do not wholly exclude the dust, snow, or other flying particles, but they aid greatly in keeping the inclosed parts clean.

The section B, which inoloses the pulleyf and forms a continuation of the part A, is borne wholly by the frame 0. This section receives the arbor b of the dynamo, said arbor projecting through one side of the same, as seen in Figs. 1 and 2. As the dynamo has a rocking movement, asbefore explained, the arbor b rotates in a packed aperture in a plate q, which is slidably mounted in keepers 'r on the side 3 of the casing. This-side is fixed to the frame 0 as well as the bottom t. The other side, 8, (seen in Fig. 2,) as well as the top it and front r, are removable, being held in place partly by swing-bolts w and w, which engage slots in the respective ends of a bar 11'' on the front '1}. The swing-bolt w is hinged to the fixed side 8, and the opposite swingbolt,w',is longer and extends back to a bracket 10 on the frame C, the bolt being hinged to said bracket. When the nuts on the outer ends of these bolts are loosened, the bolts may be swung out laterally, so as to free the removable parts of the section B. The cover or top plate to is held in place also by screws 203, although there need be. only a few of these. The pendent flange on the front end of the cover u takes over the upper edge of the front plate '0, and the two plates are clamped together by a bolt and nut 10 the said bolt being attached to the front plate and engaging an aperture or way in the reinforced flange u on the top plate or cover.

The object in making parts of the casing interior thereof for inspection and cleaning.

In spite of all efforts to keep out snow or the like from the casing some will get in, owing to the necessity for leaving a space about the car-axle, and such particles-usually snow in winter-ordinarily collect in the end of the casing near the axle (at the left in Fig. 1) and is carried forward to some extent by the belt g, (to the right-hand end in said figure.) To remove any accumulation in the casing from the cause named, the latter is provided at the respective ends of its bottom with ejector devices D for exhausting such accumulation when the car is in motion. This exhauster or ejector device consists of a pendent tube or pipe 1 having in its sides oppositely-disposed openings each provided with a flared mouthpiece 2. When the car is in motion, the cross-current of air through the mouthpieces and transversely of the pipe creates a partial vacuum, and the flow of air from the casing carries with it the snow, dust, and the like.

' The casing will be substantially rectangular in cross-section, as seen in Fig. 4. The truck-beam 0 may be cut away, as indicated in the drawings, to provide room for the belt should the construction and disposition of parts require such cutting.

Having thus described my invention, I claim 1. A casing for the purpose specified, comprising the two sections A and B, the former having dust-guards at its sides and the latter having at one side an apertured slide to embrace the arbor of the dynamo, and a frame connecting said sections and having flanges to rest on the transverse beam of the truck.

2. A casing for the purpose specified, comprising the section A, having a removable lower portion 2, and dust-guards at its sides to embrace the car-axle, the section B, having a slide at one side to embrace the arbor of the dynamo, and a connecting-frame G between said sections and connecting the same.

3. A casing for the purpose specified, having means for supporting it from the truckframe, dust-guards at its sides to embrace the car-axle, an aperture in one side for the passage of the arbor of the dynamo, a slideplate over said aperture and adapted to embrace said arbor, and keepers for said plate.

- 4. A casing for the purpose specified, having a lower, removable portion 2, apertures in its sides for the car-axle, and dust-guards on its sides, each of said guards consisting of an upper and lower conical or tapered part1), the upper part being secured to the fixed side of the casing and the lower part secured to the removable portion 2 thereof, the margins of the partsp overlapping, as set forth. readily removable is to aiford access to the v 5. The combination with the cross-beam O and transverse bar 01, of a car-truck, of a casing for the purpose specified, comprising the main, or larger section A, the smaller sec tion B, and the frame C secured to the truckbeam 0, said section A being provided with a brackett' supported on the bar (lat one end and secured to the frame 0 at the other end, and said section B being provided with a removable side, substantially as set forth.

In witness whereof I have hereunto signed my name, this 24th day of April, 1903, in the presence of two subscribing witnesses.
