PatentedMay' 18, 1915.
Original application filed May 5, 1914, Serial No. 836,495. Divided and this application filed August 25,
1914. Serial No. 858,464.
To all whom it may concern: 7 r
Be it known that I, ANDREW YURow, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful m a conduit under the track and the plow or shoe is carried by the car and extends down into the conduit to have sliding contacts with the conducting rails for collect ing current therefrom for driving the motor on the car.
The object of the present invention, which constitutes a division of my pending applicat-ion, filed May 5, 1914:, Serial No. 836,495, is to provide a simplified and improved plow which is more durable and can be more readily and cheaply repaired in case it becomes broken. The parts of the plow which become broken most frequently are the resilient plates mounted on each side thereof for contact with the conducting rail. The present invention aims to simplify the construction and mode of attachment of these plates, whereby the breaking thereof will not be such a serious loss and new ones may be very quickly substituted.
Other objects will appear as the description proceeds.
The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification, and then more specifically defined in the claims at the end of the description.
In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts in the several views, Figure 1 is a side elevation of a plow constructed in accordance with this invention. Fig. 2 is an endview thereof, contact pins for across-over being also illustrated, and Fig. 3 is a horizontal sectional View taken just above the contact-plates.
The plow A may have its lower portion formed of insulating material and be T-shaped, the vertical stem portion B of the T being preferably fiat and smooth on both sides. Pairs of bored lugs C are carried by the portion B near the ends of each side thereof, the lugs ofeach in vertical alinement.
pair being arranged The contact plates D are made of resilient steel of uniform thiclmess and are bowed as best llustrated in Fig. 3. The ends of'each of said platesare reduced in width forming shoulders E. These reduced end portions of,
the plates are curvedin the opposite direction from the curve. or bow of the plates themselves, and are adapted to fit loosely between the pairs of lugs C. Cotter-pins F are passed through the bores .of the lugs. C and serve to hold the contact plates D in proper position at the sides of the plow and at the same time allow said plates to have the necessary limited sliding movement to permit them to be compressed or flattened out to a certain extent when the plow is inserted between the conducting rails (not shown), as will be readily understood. The shoulders E will come in contact with the lugs C and prevent undue longitudinal movement ofthe plates.
It will be observed thatthe construction 7 1 v and means of attaching the plates to the very easy matter to remove said plates and substitute others when necessary or desirplow, as shown and described, makes it a Any suitable means for conducting the electric current collected by the plates -D from theconducting rails to the motor (not shown) on the car may be employed, such as the wires or cables G which are illustrated in Figs. 1 and 3. These wires or cables are flexible so that they do not interfere with the in and out movement of the plates D to the inner surfaces of which they are electrically connected. Said wires or cables G are passed up through passages H provided in the body of the plow which, as hereinbefore explained is made of insulating '''material, see Fig. 3, and issue from the upper end of the plow as shown in Fig. 1.
The head K of the lower T-shaped portion of the plow may be provided with horizontally extending auxiliary contact plates L, as shown in Figs. 1 and 2. These plates L may be electrically connected to the corresponding plates D by wires M and are designed for carrying-the current at crossovers, contact pins N, Fig. 2, being arranged at either side of each cross-over for that purpose. These pins N are electrically connected to the conducting rails (not shown) and are arranged in the path of the plates L, whereby said plates are adapted to bridge pins on opposite sides of each cross-over and thus preserve the current unbroken. This provision for carrying the current over crossings does not, however, constitute any part of the present invention, the same being covered in another application already referred to, and need not, therefore, be further illustrated or described'in this application.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is A plow for conduit railways having pairs of bored lugs on the opposite faces thereof, bowed collecting plates each made of a sini gle piece of resilient metal having a central portion wider than the space between the lugs of each pair, and reduced end portions to fit loosely between said lugs, abrupt shoulders being formed at the junction of said reduced ends with the central portions of the plates for contacting with the lugs and thereby limiting the endwise movement of said plates with respect to the plow, and removable pins passed through the bores in the lugs for detachably retaining said plates in operative position.
In testimony whereof I have signed my name to this specification in the presence of two attesting witnesses.
ANDREW YUROW.
