AUT'OMATIGALLY-OPERABLE VALVE.

. Application filed July 1, 1911, Serial No. 636,464.

To all whom it may concern Be it known that 1, CHARLES EDWARD HASTY, a citizen of the United States of America, residing at Elgin, in the county of Kane and State of Illinois, have invented a new and useful Automatically-Operable of which the following is a specification, reference being had to the accompanying drawings, illustrating same.

' My invention relates to valves of various characters, and to automatically-operable mechanism therefor.

The principal objects of my invention are, to provide an improved valve of the character herein set forth; to provide improved automatically-operable mechanism for such alves; to provide improved means for automatically opening the valve as desired; to for holding the valve plug or plunger in set, or closed, position; to provide an improved packing box for such valves; and to provide other improvements hereinafter set forth.

Other objects will be apparent from the following specification. i i

The spring packing material preferably used in the packing box of this invention is described and claimed in my co-pending application for Letters Patent of the United States, Serial No. 631,599,15iled June 21, 1911.

In the accompanying drawings illustrating one .form of my invention, Figure .1 is a vertical or longitudinal cross-sectional view of the valve of the invention, with portions shown in elevation, showing the valve in set position; Fig. 2 is a similar view showing the valve in operated position; Fig. 3 is a plan viewcof one of the packing rings used in the packing box of the invention; and Fig. 1 is a cross-sectional view of the packing ring of Fig. 3, taken online X'X thereof.

Like characters refer to like parts in the several figures.

In various places where valves are used, such as on air-brake systems of railway cars, it is very desirable tobe ablev to automatically and quickly open a valve at certain times, and to be able to control .suchoperation of the valve from a distance from the valve by some simple and easily-operable In railway block-signal systems it is also very desirable in certain instances to have such valve control, operated auto Specification of Letters Patent.

matically to control the brakes of thecars. The advantages of such apparatus and such a system are very marked. For instance, with the apparatus of this invention, in stalled in a suitable system, a motorman on an interurban trolley car cannot run his car into the wrongblock without automatically putting on the brake and stopping the car. To procure these advantages, as well as others, the features of this invention are provided.

By reference to the drawings, 1 is the valve casing, having an inlet passage 2 and an outlet passage 3. \Vithin the casing 1 is provided a tapered valve-plug seat 4:

5 fits when the within which the valve plug valve is closed, as shown in Fig. 1. The plug 5 has a rod or stem 6 connected therewith and extending out through the valve casing 1 to mechanism controlling the operation of the plug. The valve-operating mechanism comprises a hand wheel 8 attached to the stem 6, a pair of arms 9 9 pivoted at 10 lO be'tween pairs ofwings 11 11 on the handwheel member 8, links12 12, respective arms 9 9 at'13 13 and pivoted together at 1 1, for holding the arms 9 9 against operation, a heat-susceptible. or explosivemember 15, either'an electrical heatcartridge or a cartridge of gun-cotton or some other explosive, removably held be-v tween two terminal members 1616 which are secured to the links 12 12 respectively,

12 against operation, and a coil spring 17 surrounding the stem 6 an box 7 to operate the plug 5, wheel 8, arms 9 9, and links 12 12, tothe positionshown in Fig. 2 when the cartridge15 gives way pivoted to the v p d acting expansively betweenthe .operable plug 5 and the stationary packing or is removed from the members 1616. I

' Nuts 20 and 21 screwed onto the casing 1 as shown, are for thepurpose of holding the arms9 9 in theposition shown in Fig. 1, andfor the purpose of forcing these arms 9 9'downwardly when screwed up tightly thereagainst, to draw the plug 5 tightly into theseat to tightly. close the valve against the pressure'of spring 17 and the pressure of the fluid in the inlet passage 2. v

Thepacking box 7 comprises packing rings 18 and 19 between which the springpacking material at 7 is placed, the ring 19 being held in place by a bushing 22 screwed into the end of the casing 1, and the ring 18 being held in place by the coil spring 17 bearing thereagainst. The lower end of sprmg 17 is held attached to the ring 18, after being screwed into the recess 23 with one convolution of the spring under the out weirdly-turned portions 24 24, by the said outwardly-turned portions 24 24. This enables the ring 18 to be removed with the spring 17 from the top of the valve caslng, Wheifthe nuts are removed from the stem 6. When the plug 5 is operated to the position shown in Fig. 2, the spring 17 in expanding reduces the pressure on the spring packing material 7 and thereby permits the latter to loosen its hold on the stem 6 to I allow the mechanism to operate freely to the the members first drawing. the parts to the position shown in Fig. 1 against the tension of spring 17, 20 down position shown in Fig. 2.

' The cartridge 15 may be heated by an electric current in the circuit 26, if an electrical cartridge, or exploded by a spark therein from the circuit 26, if of gun-cotton, or removed from the members 16 16 by some suitable means, to permit the operation of the apparatus from the position shown in Fig: l to the position shown in Fig. 2. When it is desired to reset the apparatus for another operation, it is only necessary to place a new or repaired cartridge between 16 16 as shown in Fig. 1, after and then screwing the nuts 21 and tightly against the ends of the arms 9 9 to tightly draw'the plug 5 intothe seat 4.

may operate the valve byitself. It will be readily seen that when the mechanism is in the position shown in Fig. 2, the valve passage is open. f v

, The wheel member 8 has a hollow cylindrical portion 27 thereon, attached to the wings 11 11 and adapted to move over the v the valve casing 1 when the valve is operatedfrom one position to another. i

The portions 5, 6, 8, 9,9, 12, 12, 15, as a whole, may beturned around relatively to the valve casing 1 if desired, to cause the plug 5 to fit more snugly into the seat 4 in case thejfit is better in one position than in Forthe spring 17 I preferably use piano prevent rusting.

Of course the packing box herein set forth may be used on other devices besides valves.
