4lowing isa specification. l

One obj ect of our invention is to provide a simple and positively-acting device for supplying lubricant to one or any number of .bearings of amachine, the device illustrated being particularly designed for use in connectionwith themotor or motorsand other mechanism commonly found on street-railway equipments.

' Another object of the invention is to provide a device of the character noted which will require but `little attention under operating conditions and which shall not be likely to get out of order;

It is further desired toso lconstruct and arrange the device that itmaybe applied to existing car equipments ywithout reqluinring -additions or changes therein and whic 'shall .at the same time be of relatively inexpensive construction.

These objects we attain as hereinafter set forth, reference being had to the accompanying drawings, in which-l Figurel isa planview of a car-axle and its driving-,motoras found in a well-known vtype ofcar equipment, illustrating our in-y vention as applied thereto.' Fig. 2 is a side elevation of the motor and other portions of the equipment shown in Fig. 1, further illus trating the arrangement of our invention rel-g Fig. 3 is a plan view of that* form of our lubricating device shown in Fi s. land 2. Fig. 4.- i's a side elevation ofthe e-l vice shown in Fig. 3. Fig. 5 is a vertical sec tion taken on the line 5 5, Fig. 3. Fig. 6 is a perspective view, on an enlarged scale, illustrating the detail construction and arrangement of the oil-feed bucket'and its adjacent parts; and Fig. 7 is a vertical section of a special form of oil-bucket having means for adjusting its capacity.

In the above drawings, A represents a form of electric motor commonly used for propelling street-railway vehicles, which in the present instance is shown as operatively connected to a' car-axle B, having wheels b. .The

there are, in addition to these, two bearings a, whereby the motor-frame' is partiallyV supported from the axle B, as well as two bearings a, wherein is supported the armatureshaft of the motor.

The oiling mechanism hereinafter described has been particularly devised to supply the above -noted bearings with lubricant, and while certain portions of it have been adapted to the partlcular type of motor in connection with which it is illustrated it is to be understood that it may, without departing from our invention, be employed to supply lubricant to the bearings of any other form of machine. i

In the present instance our lubricating device consistsof a casing. C, consisting of two containers c, in the present instance of rectangular Section and'united by an integral plate 0':

Asbest shown in Figs. Zand 5, the containers and their connecting-plate are arranged to iit upon the'sloping portion of the frame of a motor A, to which'the device is held by means of a hook-bolt a2, designed to enga e a lifting ring or eyebolt a?, commonly foun in motors of the type illustrated, and

passing through a suitable boss c2 in the'casting C, t`which it is held by a nut, as shown in Fig. 1. Downwardly-.projecting lugs c3 Iare preferably provided'at the lower corners of the casting C for the purpose of engaging a vertical portion of the motor-frame to preventpossiblemovement of the lubricating device thereon.

A'second pair of lugs is also provided on arm d, carrying at its outer end a friction roller or wheel D, provided with an eccenltried Also fixed to the spindle c5 is a sec- 'ond arm d2, between the end of which and the body of the casting C is a spring d3,where by said arm d2 is pressed outwardly, lwith the result that the friction roller or wheel D is pressed into en agement with the nain shaft or axle B. A t rd pair of lugs c, preferably at the top'of the casting C, provide bearings for a spindle or shaft e, to which is `fixed a forked arm E, forming an eccentric-rod designed to be actuated by the eccentric d.

In the present instance this rod may bedeaxle bearings or boxes are shown at b', andll scribed'as splitrat'its lower-end, so 'that its IOO two branches engagethe eccentric d', and these branches are adjustable as to the distance between them by means of a bolt c. There are also fixed to the spindle e two other arms e2, one for each of the containers c, and each of these arms has at its end a pin or small spindle e3, carrying a pawl e4, pressed into engagement with the teeth of a ratchet- Wheel F by means of a spiral spring e5 on said pin.

The above-mentioned ratchet-wheels are carried upon bolts e7, supported by portions e8 of the casting C, which extend within each of the reservoirs c. Each of the ratchetwheels -F is prevented from moving backward by means of a flat spring c", suitably supported within the container, and has projecting from one of its faces orsides in a line substantially parallel to its axis of rotation a pin or spindle f, to which is hung an oilcarrying bucket G, which in the present instance consists of a piece of metal having in it three holes or recesses g.

In the same vertical plane as the holes or recesses g and transverse to the axis of rotation of the ratchet-wheel F a series of passages c10 are formed in a portion a8 of the casting C, in the present instance extending throughl said portion in horizontal lines. One passage of each set opens on the side face of the casting C and has connected to it the pipe c11 while the others of each set open, respectively, on the end faces of said casting and have connected to them pipes cl2. As shown in Fig. 1, these various pipes are connected to the bearings a, a, and b of the armature-shaft and main axle.

Under operating conditions the friction roller or wheel D is pressed in engagement with the axle B, so that as this latter turns said roller is also turned, and with it the eccentric d. Revolution of thisrlatter gives, through the eccentric-rod E, an oscillatory movement to the spindle or shaft e, which in turn alternately raises and lowers the pawlcarrying end of the arms e2 in each reservoir c. AS a consequence the pawl e4 on each arm being in engagement with the teeth of the ratchet-wheel F causes a partial revolution of this latter as the arm is raised and then as the arm is lowered moves idly over one or a number 'of the ratchet-teeth, while the ratchet itself is held from turning by means of the spring 09. The continued periodic movement of the ratchet F causes the oil-bucket G to be dipped into the body of oil within the container C, so that it is filled with the same and afterward raised and turned to a substantially horizontal position as it is brought over the portion cs of the casting C Within the container.

It will benoted that the shape of the bucket G is such that previous to its engagement with the upper part of this portion e8 it tends to hang in a position such that liquid is retained in its recesses g, while as it passes over the top of this portion it is forced to assume a substantially horizontal position, thereby being made to discharge the liquid in its recesses into the corresponding passages c1, as clearly shown in Fig. 6. By this means the bearings connected to the various passages 010 are periodically supplied with an amount of lubricant depending upon the capacity of the holes or recesses g, the rate of said supply being dependent upon the rate of rotation of the axle B.

If desired, the capacity of the buckets may be adjusted in any desired manner-for example, by means of a screw g, as shown in Fig. 7, which may be made to enter the bottoms of the recesses for varying distances, so that, if desired, one of the passages ci may be supplied with a greater amount of lubricant, depending upon the requirements of the bearing to which it is connected. We preferably enlarge the mouths of the passages clo, as well as the openings tothe recesses in the bucket-piece G, to facilitate the entrance and discharge of the lubricant.

It is obvious that the number of recesses g, as well as the number of passages c1, may be varied: without in any way departing from our invention, so that the device will supply lubricant to any desired number of bearings. Covers cl3 are preferably provided for the containers c.

We preferably provide a cover or casing c14 (shown in dotted lines in Figs. 4 and 5) for preventing access of dust or grit to the eccentric d and its associated mechanism, this being held in place by pins which engage suitable lugs 015 on the casting C.

From the above description and the accompanying drawings it will be noted that our ubricating device may be applied to existing car'equipments without requiring any change whatever in them, with the ossiblc exception of the drilling of holes in t ie bearing-covers to permit of the entrance of the pipes c and cl2, it being further noted that the number of containers c, with their individual equipments, is altogether immaterial, since the operation of the device is the same Whether one or a plurality of these be provided.
