SPECIFICATION forming part of Letters Patent No. 601,359, dated March 29, 1898.
Application filed March 5, 1897. Serial No. 626,060. (No model.)
To all whom it may concern: 7
Be it known that I, CHARLES STADTFELD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Street-Railway Switches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in mechanism for shifting switches for streetvices and the friction between the engaging parts reduced to a minimum.
Referring to the accompanying drawings, Figure 1 is a side elevation of the inclosed mechanism, the casing appearing in section. Fig. 2 is an elevation looking in the direction of the arrow at, Fig. 1. Fig. 3 is a similar section, reduced, looking in the direction of the arrow 1), Fig. 1. Fig. 4 is an enlarged detached side elevation of slotted oscillating bar and block.
Throughout the specification similar letters of reference indicate corresponding parts.
A designates an .inclosing case that when in position lies flush with the track between the rails.
A is an auxiliary case adjacent to the firstnamed case and connected therewith by a tubular connection A".
B designates an oscillating shaft mounted in box-bearings B in a central longitudinal position in both cases.
C designates a gravity or balance plate rigid on said shaft and movable therewith from the position shown in full and dotted lines, Fig. 2. This plate serves to hold the shaft in position when the latter is rotated in either direction.
D and D designate two reciprocating bars pivoted to the plate 0 at a central point, with their outer ends similarly connected to reciprocating levers E and E, having curved extensions E E, upon which antifriotion-roll- 'ers F F bear. These rollers are mounted in tripping-pieces G G, that are pivoted at one end to the side of the case A. The trips G G project through openings in the top of the case and are eXposed'to a contact with a suitable plunger operated from the platform of the car' (which it has not been deemed necessary to illustrate).
Referring to the mechanism inclosed in case A, H designates an oscillating disk or circular block keyed to the shaft B.
I is a shifting plate or lever pivoted centrally to a bearing I, projected from the case.
The lower end of said plate has two slots J, of the form shown in Fig. 4, into which are inserted pins II, that project from the block H. These pins are inclosed by antifrictionsleeves H".
K, Fig. 3, designates the switch-shifting bar, which ismovable back and forth on rollers M M, mounted on the sides of the case A. One end of said bar is connected to the switch-tongue N and the other end is free. The entire bar is concealed beneath the cover of the case.
In Fig. 3 O is one of the rails. It has not been thought necessary to illustrate the mechanism on the car through which the shifting construction and consists of a-vertically-movable'piece that may be lowered through an opening in theplatform of the car to come in contact with either of the trips G G to actuate the levers E E and in turn the shaft B. When the latter is moved in either direction, the balance-plate C is carried in the same direction, as shown in dotted lines, Fig. 2, and holds said shaft in position. The movement thus imparted to the shaft rotates the disk or block H, which moves the oscillating lever I,
as shown in full and dotted lines, Fig. 4. In 1 this movement the pins H, with their antifriction-casings, move in opposite directions in the slots J and lock the switch in its shifted position until one or the other of the trips G G is again actuated through the plunger on the car, as hereinbefore stated. The casings are p practically dirt-proof, so that any foreign matter is prevented from entering it. The movements imparted to each of the parts when the trips are actuated are positive and free from any vibrations. The trips G G, it will be observed, have their ends G G tapering, so that whether they occupy a lower or upper position the space between the case and their ends will be practically closed against the entry of dirt. Thetrips may also be pressed upwardly by suitable springs, so that they will project above the track in a proper position after each depression.
Having fully described my invention, I claim 1. In a switch-shiftin g mechanism, the com- .bination with an oscillating shaft having a switch-tongue is connected, the said. plate having two inwardly-terminating slots in its lower end; a block rigid on said horizontal shaft, and having pins set at different points that project into the slots insaid plate, and means for actuating the horizontal shaft to throw the upright plate, and the switch-tongue connected therewith, substantially as shown and described.
3. In a switch-shifting mechanism, a horizontal shaft; a gravity or balance plate attached thereto to hold said shaft in position; levers connected with said balance-plate, and trip-pieces operating on said levers to actuate the shaft, in combination with a slotted os-. cillating plate to which the switch-tongue is connected; a disk rigidly connected to said horizontal shaft having pins thereon that project into the slots in said oscillating plate, the said pins serving to impart movement to the plate and to hold it and the switch in position, substantially as shown and described.
I11 testimony whereof I affix my signature in presence of two witnesses.
CHARLES STADTFELD.
