PNEUMATIC W-lNDlNG APPARATUS FOR PRINTING-TELEGRAPHKS.

, SPECIFICATION forming part of Letters Patent No. 316,688, dated April 28, 1385.

(No model.)

To all' whom it may concern.-

Be it known that I, HENRY VAN HoEvEN- BERGH, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Winding Devices for Printing-Telegraph Receiving-Instruments, of which the following is a specification.

My invention relates to a class of inventions employed inl connection with printing-telegraph instruments for supplying the force necessary to actuate the same.

The object of the invention is to provide means for conveniently storing any required amount of energy and causing the same to be automatically applied to the instrument at such times and in such quantities as may be required,

The invention consists in organizing the apparatus substantially as follows: Applied to a printing-telegraph instrument of any convenient form is a spring or a weight designed to be wound up by means of a pinion and a rack-bar applied thereto. The rack-bar is impelled in the proper direction for winding the spring by means of a system of pneumatic tubes and air-chambers or bellows. For this purpose a primary bellows is employed,which is equipped with a tread1e,whereby the operator may conveniently actuate it. By means of this bellows air is forced into a storage reservoir or bellows, and from this bellows it is led to a third air-chamber or bellows, which is employed for actuating the rack-bar which is carried thereon. This last-named bellows is `provided with an automatically-operating fro movement of the winding-bellows the valve which permits the air to escape therefrom is closed when the bellows is compressed, and is again opened when it has been completely expanded.` The valve leading from t-he storage-chamber to the winding-bellows is For the pur-V also automatically opened after the bcllows- 5o valve has been closed, and it is itself closed before the bellows-valve is again opened, thus affording an intermittent supply of air to the winding-bellows. For the purpose of automatically giving a signal when the air contained in the storage or supply chamber is nearly exhausted, I employ a circuit-closing device, which servesat that moment to complete the circuit-connections of a local battery through an alarm-bell, thus giving warning to the receiving-operator.

In another application of even date herewith, Serial No. 139,87 6, I have shown certain lparts shown and described herein, but the parts herein claimed are not claimed in said other application.

In the accompanying drawings, Ifigure l is an elevation showing the organization of the pneumatic chambers and their connectingtubes. Fig. 2 is a side elevation showing a 7o portion of a printing-telegraph instrument, together with the device employed for connecting the pneumatic apparatus with the same; and Fig. 3 is an end elevation of the y same. The invention will be described in connection with a receiving-instrument,@though it may be applied to a transmitter.

Refeng-to the drawings, A represents a base upon whiclrthe several parts of a receiving-instrument aresupported. This instrument is of any well-known construction, and is designed to be actuated by means of aspring, C, which is carried upon a shaft, c. and communicates its motion, through a system of S gear-wheels, to an escapement-wheel, d.

For the purpose of winding the spring`C a pinion, e, is applied to the shaft c, and it is coupled thereto by means of a ratchet-wheel, e', and pawl e2, in a manner well understood. Applied to thepinion eis a rack-bar, f,which is driven longitudinally by meansjof the pneumatic apparatus hereinafter described. The parts are so organized that during the upward movement of the rack-bar the ratchetwheel e will be engaged by the pawl e2 and the spring will be wound. During the downward movement of the rack-bar, however, the

ratchet-wheel e will'be allowed to turn freely, and no resistance, therefore, will be oficred to the descent of the rack-bar.

For the purpose of actuating the rack-bar the following system of pneumatic apparatus is employed: A bellows, p', provided with a treadle, r,is locate'd'i'u `a convenient place relative tothe receiving-instrument, so that the operator may at any time actuate'the same.

1c A spring, r2, normally forces the trea'dle upward, and by means of 'the vdownward pressure exerted by the foot upon the treadle and the return movementoccasioned by the spring the bellows p may be alternately compressed i5 and expanded. A valve, s', is applied to this bellows in a well-known manner for permit- .ing the sam-e to be iorcedoivitward through a 2c tube, t, when the bellows is compressed. The

tube't leads to a storage-bellows, p2, in which l `it is designed that a quantity ot' air received trance of the tube t into the bellows p2.

3o the purpose of placing the air contained therein under suflicient pressure to accomplish thc winding ofthe spring C, in the manner hereinafter described. An outlet-tube, t2, -leads .from-the bellows p2 to a third bellows, p3. In-

3 5 seitcd within the tube #is 'a centrally-pivoted -valve, s3, which is so constructed that the force .ict lthe air passing through the tube t2 will not 4o nor open it if it is closed.

4 5 formed an elongated opening or loop, a3.

actuate it in either direction-that is to say, the air will not close the valve if it is open,

A crank, a', connects the arbor of the valve s with a pitman or rod, a2, extending in..a direction parallel yto the direction of :movement of the upper portion of the bellows pi", In the rod a2 there is arm, a4, extends A.from the outlet-valve s of the bel-lowsv p3 rthrough the loop ai. This arm 4is .engaged by the upper Vextremity of the loop """wwwwhen the bellows lis expanded, therebyforcing 5o the vavesto open, after having irst caused the valves to be closed, by turning the crank a1. throughrthe arm a2, sion of the bellows p the arm ais engaged by 4.the lower-end of the loop a3., and the valve sL .fis thus-closed. The same movement of the ,bellows also causes the roda2 and the crank a toopenjthe valve-s. Airesh supply of air is thusadmitted to the chamber p, which immediately exp'ands. At the upper limit of its 6o motion the valve sg-is again closed and the valves,4 opened, and the operation is repeated. Sollong, therefore, as a supply of air is contained Qin the'b'ellows p2, the bellows. p3 will bel The movements of the upper portion of the bellows alternately expanded and compressed.

For the purpose of causing an alarm to be automaticall given when the bellows p2 is nearly exhausted, I employ a local battery, W', one pole of which is engaged through a conductor, l, with a'contact-spring, w', carried upon the stationary portion o1" the bellows The bellows pf will then. be
