SPECIFICATION forming part of Letters Patent No. 393,862, dated December 4,1888.
Application fil d Au t. 23, 1886. Renewed February '6, 1888. Serial No. 263,167. (No model.)
To all whom it may concern:
Be it known that I, HENRY SILVEsTER, of St. Louis, Missouri, have made a new and useful Improvement in Motors, of which the fol- '5 lowing is a full, clear, and exact description.
This improvement is based upon the vertical oscillation incident to the use of a spring supported car-body.
"The annexed drawings, making part of this specification, exhibits a desirable mode of carrying out the improvement.
Figure l is a side elevation, partly broken away, exhibiting the'improvement and enough of a car for an understanding of the opera- I 5 tion of the mechanism. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1; Fig. 3 is a plan of one of the pumps, and Fig. 4 is a vertical section on the line 4 4 of Fig.
The same letters of reference denote the same parts.
The car A, which may be a street or any car," is of the ordinary construction, saving as' modified by the improvement in question, and
that its body a, by reason of its being sup- 2 5 ported upon springs, is adapted to oscillate vertically as the car is used.
The improvement consists in combining,
substantially as hereinafter described and claimed, a telescoping pump. with the carbody, so that the varying oscillation of the car-body can be properly utilized. I
To this end the car is provided with one or more pumps, B, suited, say, for compressing air, and so connected with the car-body a and 3 5 car-axle a, or with parts respectively attached to the car-body and car-axle, as to cause the vertical oscillation of the car-body to operate the pump, and as, perhaps, a desirable means therefor the pump-cylinder b 40 is attached to strips or plates a upon the carbody depending therefrom, and the pistonrod 1) is attached to the car-axle extending upward therefrom, and, in the place of a single cylinder and piston, a telescoping construction is adoptedthat is, the piston-rod b at its upper end is attached to the piston b Fig. 4, which works in the cylinder-section b This section in turn, and as a piston, works in a second cylinder-section, b. This section b similarly, as a piston, works in a third cylinder-section, b, and the section I) works as a pistonin the upper cylinder-section, b. Any desirable number of cylindersections maybe used. The air is admitted into the lower section through the passages 11, which are provided with a valve, If, seating downward. An air-passage, b leads from the lower section into the section above, and from the section b the air can pass through the passage U into the section b, and from the section U the air can pass through the passage 11 into the section b. All of these airpassages are provided with check-valves simi larly to the passage 1), to prevent the air from escaping backward when the sections are closed into each other and to admit the air when the sections are opened out from each other. i
' A spring, C, in each section serves to open the section out as the car-body rises, and when the car-body falls the springs yield and the air is compressed within the sections, passing upward through the sections successively, and from the uppermost section is discharged through the passage D to the point where it is desired to utilize it.
In the present instance the compressed air, as indicated by the broken lines D, Fig. 1, is conducted through a pipe to an air-reservoir, E,whence, and by means of suitable pipes, F, it is delivered to the cylinder or cylinders G, whose rods g connect with the cranks g of the car-axle.
As the details of that part of the construction used in applying the compressed air do not enter into the present improvement, they need not be described, nor shown in the drawings. It is sufficient for my present purpose to indicate an application of the power such as the propulsion or the starting of the car.
One or more of the pumps B may be employed andat various parts of the car, and when more than one is employed pipes may lead from one to the other, so as to combine the diiferent bodies of compressed air. For. instance, in addition to the pumps B under the central portion ofthe car-body, they may be inserted, as at B, in the places of the customary springs, in which position they serve not only as springs to support the car-body, but also as pumps to compress the air which may be delivered through the pipes II into the central pumps, B. Pipes I and J may lead I from the tank E to the pumps B and B, re-
spectively, for the purpose of reconveying to the pumps the air or liquid which the pumps have transferred to the tank.
It will be noted that the vertical oscillation of the car-body continually varies in length. Consequently it will not answer to use a pump of fixed length. The pump should be a telescoping one and one in which the air after being compressed backward cannot expand again. The pump shown expressly provides for this varying vertical stroke of the carbody. If the'car-body descends one-half an inch, it operates one section of the pump; if an inch, two sections, and so on. This feature ing suitable pipes and valves for transmitting the compressed air to said engine, substantially as described.
5. The herein-described car havingthe telescoping pump 13, constructed as set forth,
I each section being provided with a spring, as
and for the'purposes described.
(3. The combination of the car-axle, the oscillatin car-body, the telescoping spring-actuated pump, constructed substantially as described and operated by the oscillation of said car-body, and a pipe leading from said pump to an air reservoir or cylinder, substantially as described.
is one of very great value and importance,and in practice accomplishes in a wholly novel way the most substantial and useful results.
I claim 1. In a car, the combination of the car-axle, the oscillating car-body, and an interposed airpump, one part-say the piston-rodbeing attached to the car-axle and the other partsay the cylinderbeing attached to the car-body, as and for the purpose described.
2. In a car-motor, substantially as set forth, a pump placed between the axle and body,
said pumps thereto, the pipe F,and the caraxle and crank-connection, substantially as each section of said pump provided with a 5 spring, the fixed part of said pump being fastened to said axle and the movable part of said pump being fastened to said body, as and for the purpose specified. 7
3. The combination of the herein-described car-body and telescoping pump, constructed substantially as set forth, each section being provided with a spring and car-axle, substantially as described.
4. The combination of the oscillating cardescribed.
E). I11 a car-motor, and in combination with the car-body and operated by its vertical oscillations, a pump composed of cylinders 11 b b" l), the several sections provided with valved air-passages, and each movable section acting as a piston in the section above it, each sec- 1 tion being provided with a spring, substanbody, the car-axle, the pump, constructed substantially as set forth, each section being provided with a spring, and the engine, includtially as and for the purpose set forth.
