CROSBY STEAM GAGE AND VALVE COMPANY,

OF BOSTON, MASSA- PRESSURE-GAGE.

SPECIFICATION forming part of Letters Patent No. 643,876, dated February 20, 1900. Application filed January 1'7, 18%. Serial No. 666,934. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK LANE, a citizen of the United States,residin g at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Pressure-Gages; andI do hereby 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 it-appertains to make and use the same.

This invention relates to an improvement in pressure-gages, more especially to an improvement in a pressure-gage provided with avalve which is a part'of the gage structure. Heretofore the valves for such gages have been separate from and connected to the gages; but in my invention the valve is made a part of the gage structure, so that when the gage is put in place the valve is there ready for operation.

The object of the invention is to provide a pressure-gage with a valve of such construction that in the ordinary and usual use of the gage the steam may pass in and out with a steady pressure, but in case of any rapid variation or fluctuaton of the flow of steam in or out of the gage there will be no shock, as the valve will permit only a steady flow of steam and acts as a buffer against any violent expansion.

To this end the invention consists in providing a pressure-gage with a steam way or passage which permits the flow of steam when under a steady pressure, butis choked when there is a sudden expansion.

In the annexed drawings, Figure 1 represents a face view of a gage provided with the invention, a portion-being shown in section, so-as to display the invention. Fig. 2 shows an enlarged perspective view of the interior piece which is to be inserted into the-socket.

In the drawings the letter A represents an ordinary pressure-gage to which the invention is applied. The socket B, by which the pressure-gage is secured to the place where the pressure is to be measured, is threaded at b in the usual Way on the outside and within the gage has a thread I), to which the usual tube-spring O is secured. Outside of the gage A the socket 13 has a threaded bore b and from this bore there leads a passage 19 which communicates with the interior of the tubespring 0. Within this threaded bore 6 is inserted a shell D, threaded on the outside to engage the threads of the bore 12 and also threaded on the inside, the threads being shown at d and d. In the closed end 01* of the shell D is made a central passage (1 Within the shell D is a plug E, the exterior threads 6 of which engage the interior thread d of the shell D. This plug E has a central bore or passage e. far enough to leave a chamber F, within which is placed a ball G. At the top of the plug E the bore 6' is countersunk, as shown at 6 and around the edge of the countersink are made several notches e Also at the bottom of the passage (1 there is another countersink (1 provided with notches like the notches 6 The length of the chamber F should be less than the diameter of the ball G. The parts are put together as clearly shown in Fig. l of the drawings, the ball G resting in the countersink e and away from the countersink (1 The operation is as follows: When this gage with the ball-valve is attached to any receptacle within which there is a pressure to be measured by it the pressure passes upward through the central opening 6, Fig. 1, past the ball G, resting on its seat due to the notches e thence onward and upward through the passages into the interior of the tube-spring, where it is exerted in the usual way therein. This is the course when the pressure is constant and certain; but should there be an in.- termittent and impulsive flow then the ball G would he suddenly forced upward against the seat of the piece or shell D and there resist this impulse and allow the pressure to pass into the gage more slowly and continuously through the notches upon this seat and save the mechanism of the gage from the shocks it would otherwise receive to its detriment or destruction. The same principle is applied in the withdrawing of the pressure from the gage arising from its sudden re leases or the fracturing of any part of the mechanism to which it may be attached. In such case it will be observed that the ball G falls to the lower seat and there prevents any shock to the gage mechanism, with the results above stated. 1

This plug E is inserted into the shell D Now the advantage of this device is that the valve and gage are a concrete thing and cooperate in operation, to the constant preservation of the gage itself. Moreover, the device shown is such as to render the cost of a gage having a hydraulic valve very much less than if the gage and valve, being independent things, were united as now and heretofore. Besides this, when pressuregages are made with this valve addition the user is certain of having one that will be free from injury or destruction in use where shocks or impulses may be common, when he would not be so free in the use of the ordinary pressuregage without the hydraulic valve, and it is a fact that many users to-day use a gage for measuring high pressure without the precautionary device of a hydraulic valve to save them from injury in such circumstances, the result of which is a frequent breakage and injury to gages, to the loss of the user.

Having described my invention, what I claim is The combination, in a pressure-gage, of a case; the socket secured therein having an interior passage and threaded inside and outside; the tube-spring within the gage and having its interior communicating with the interior of the socket; a shell threaded on the outside placed within the socket and engaging the threads in the inside thereof, such shell having a passage therethrough; a plug within the shell, such plug having a bore or passage and engaging the shell with threads, there being a chamber between the inner end of the plug and shell, the passages leading into such chamber above and below being countersunk and having notches, and the ballvalve placed in such chamber, as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.

FREDERICK LANE.
