REGINALD WRIGHT'AND CHARLES SIDDALL, OF KALAMAZOO, MICHIGAN.
FEED DEVICE FOR FLASH GAS BURNERS OR LAMPS.
SPECIFICATION forming part of Letters Patent No. 748,454, dated December 29, 1903.
Application filed May 11, 1903. Serial No. 156,638. (No model.)
To all whom it may concern:
Be it known that we, REGINALD WRIGHT and CHARLES J. SIDDALL, citizens of the United States, residing at the city of Kalama zoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Feed Devices for Flash Gas Burners or Lamps, of which the following is a specification.
This invention relates to improvements in feed devices for flash gas burners or lamps.
The objects of this invention are, first, to provide an improved feed device for flash gas burners or lamps by which the gas is intermitten tly delivered to the burners; second, to
provide an improved automatic feed device tions of gas-pressure; fourth, to provide an improved feed device for intermittently delivering gas to the burners which is simple, compact, and economical to produce and not liable to get out of repair. Further objects and objects relating to structural details will definitely appear from the description to follow.
The objects of this invention are accomplished by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure embodying the features of our invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure l is a verticalsectional view,taken on a line corresponding toline l l of Fig. 2, of a structure embodying the features of our invention. Fig. 2 is a plan view of the structure appearing in Fig. 1. Fig. 3 is a vertical sectional view taken on a line corresponding to line 3 3 of Fig. 2.- Fig. 4 is an enlarged detail view taken on a line corresponding to line 4 4 of Fig. 2. Fig. 5 is an enlarged detail view taken on a' line corresponding to line 5 5 of Fig. 2. Fig. 6 is an enlarged detail view of a modification of our improved valve-controlling mechanism corresponding to the view shown in Fig. 5. Fig. 7 is a detail view of a gas-jetwith pilot in proximity as used in a gas flash-light.
In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and
similar letters of reference refer to similar partsthroughout the several views.
Referring to the lettered parts of the drawings, the base Ais preferablyin a shell open at the top and bottom, the bottom being sealed by a plate A. A receiver A is supported upon the base A. The top of the base A, which extends upwardly within the receiver A, is closed by a diaphragm B, of
leather or other suitable flexible material,
thus forming a receiving-chamber M below the diaphragm and a storage -chamber N above. The receiving-chamber M is conneoted to the storage-chamber N by a pipe D, also by an auxiliary passage 0, (see Fig. 2,) which is controlled by a screw-valve G.
The delivery-opening into the pipe D from the chamber M is controlled by the valve 0. At the delivery end of the pipe D, which is gooseneck in form, so that it opens downwardly, is a valve D, which is supported upon one end of the pivoted arm F. A suitable post F is provided for the support of this arm. On the opposite end of the arm F is a valve E for the delivery-pipe E of the storage -chamber N. The valve D is arranged within the pipe D, (see Fig. 5,) moving downwardly to close the opening. With this arrangement the gas-pressure assists in closing the valve.
Projecting from the post F over the diaphragm B is an arm G, which serves as a support for the rock-shaftf, which is formed into a crank J/ at one end and carries the upwardly-projecting arm (1 at the opposite end. On the end of the arm at is a counterbalanceweight d. Projecting from the arm d are arms 6 e, adapted to engage the ends of the pivoted arm F alternately.
The shaftfis controlled by an upwardlyprojecting standard B, carried by the diaphragm. This standard, which is preferably of wire, is formed into a loop at its upper end to allow the crank f of the shaftfconsiderable freedom of movement independently thereof. The free end of the wire B is turned downwardly at b to engage a perforation in the end 1) of the arm G, which serves as a guide therefor, so that the parts can be formed of comparatively light material. This is, in effect, a trip device, the upper and lower part of the loop serving the functions of arms or fingers.
In operation the gas is delivered to the receiving-chamber M by the supply-pipe H. From the receiving-chamber M the gas is delivered into the storage-chamber N through the pipe D, which is controlled by the valve D on one end of the pivoted arm F. The gas is delivered from the chamber N to the delivery-pipe H by the pipe E, which is controlled by the valve E on the other end of the arm F, so that when the valve D is closed the valve E is open, and vice versa. The parts are so adjusted that the valve D is closed when the apparatus is in its initial position. The pressure of the gas in the chamber M raises the diaphragm toits highest position, which shifts the weighted arms 6 and reverses the position of the valves D and E, closing the delivery-pipeE of the storagechamber N and opening the supply-pipe D. This permits the gas to flow from the receivingchamber M, and as soon as the pressure is equalized in the chambers M and N the diaphragm drops of its own weight, and through its connections the weighted arms 6 e are again shifted and the delivery-pipe D closed and the pipe E opened. The pressure in the receiving-chamber M again raises the diaphragm, and the operation is repeated. The auxiliary passage 0 is adjusted to permit a small amount of gas to pass therethrough, so that the frequency of the operation of the device is regulated and controlled therebythat is, if aconsiderable quantity of gas passes through the auxiliary port or passage the diaphragm moves less frequently than when the greater portion is forced through the delivery-pipe D. The valve 0 for the pipe D may also be adjusted, which also affects the frequency of the operation. The device is therefore capable of complete adjustment for all practical purposes.
In the modified structure shown in Fig. 6 a spring (1 is substituted for the counterbalance-weight d for overcoming the dead-center and insuring a prompt and positive actionof the valves. The counterbalance-weight is, however, preferred, as the spring requires considerable carein adj usting the tension and is liable to deteriorate with use by contact with the gas. The connection I is made to the receiving-chamber M to supply gas to the pilot of the burners. This connection could, however, be made directly with the supplypipe of the receiving-chamber. This forms, however, a very convenient connection for the pilot. The main burner appears in Fig. 7 as h and the pilot as h.
We have illustrated and described our invention in the form preferred by us on account of the economy of manufacture and durability in use. We are aware, however, that it is capable of very great variation in structural details without departing from our invention, and we desire to claim the same specifically as well as broadly.
Having thus described theinvention, what is claimed as new, and desired to be secured by Letters Patent, is
