DOUBLE THROTTLE-VALVE.

$SPECIFI'CATION forming part of Letters Patent No. 635,104, dated October 17, 1899.

I Application filed January 30, 1899. $erial No. 703.808. (N0 model.)

1 To all whom it may concern.-

Be it known that we, EDMUND H. LUN KEN, of Denver, in the county of Arapahoe and State of Colorado, and HENRY BITTER, of Delhi, in the county of Hamilton and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Double Throttle-Valves,"of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to'double throttlevalves especially designed for steam-l1oists, though capable of use wherever valves of this character may be required.

It has for its object the provision, in a single casing under one controlling means, of a check-valve and. a throttle-valve, whereby the actuation of the latter by exterior means will actuate the former, so that the best re sults are attained in the admission and cutting off of the steam.

The novelty of our invention consists in the connection of these two valves, together with their accessories, in the manner hereinafter pointed out, and it will be specifically set forth and described in the claims.

' In the accc .ipanying drawings, Figure l is a sectional central side elevation of one form of valve embodying our invention. Fig; 2 is a transverse section of Fig. 1 on the dotted line a: 00 thereof. Figs. 3 and 4 are views corresponding, respectively, with Figs. 1 and 2, but showing a modification in the construction of the check valve and its operating mechanism.

The same letters of reference are used to indicate identical parts in all the figures.

In Figs. 1 and 2 we employ a valve-casing having a transverse cylindrical bore A, upon one end of which is screwed a cap B and through which and a stuffing-box G is journ'aled a valve-stem D, carrying a suitable operating-handle E; The lower end of this cylindrical casing opens into the threaded lower exterior H of the valve, which is coupled in the usual or any suitable manner to the pipe leading to the part to be operated. Covering the opening between the cylindrical chamber A and the coupling H is an oscillatory Valve F, of the usual or any suitable construction, provided with side wings a, between which is fitted a pendent member I) on the vibratory shaft D. Between the member 6 and the bottom of the slot formed by the wings a is fitted a curved spring 0, that serves to hold the valve F closely to its seat.

Upon the vibratory shaft D is a cam G directly beneath the center of a winged checkvalve I, guided in the top of the chamber A and through a spider J at the upper end in a coupling-piece K, to which the pipe for admission of steam is connected.

The adjustment of the parts is such that when the stem or vibratory shaft D is turned just sufficient to open the port covered by the valve F the check-valve I is at that moment raised to admit steam, and the further movement of the stem D in the same direction admits steam through the valve to the extent desired. The moment the valve F is returned to cut off steam at that moment the check-valve is automatically reseated, and thus but very little wear is imparted. to the valve F.

While we have thus found that a winged check-Valve will answer the requirements of our invention, we have found that a ball check-valve is more durable and is our preferred construction. As seen in Figs. 3 and 4, this ball check-valve I is seated in the same manner as the wing-valve I in the opening just over the cylinder A and it is operated by a lever d, pivoted as at c, Fig. 4, and carrying a roller f in contact with the cam G and has above said roller a cup-shaped portion bearing against the under side of the ball check-valve l, the adj ustment, as before, being such that the moment the valve F is ready to uncover its port the ball check-valve I is raised from its seat to permit the free passage of steam to the extent that the valve F is opened. By this simple construction and arrangement of parts we are enabled to provide a quick-acting valve for steam-hoists'and the like, wherein the check-valve constitutes the main valve for admitting and cutting off the steam without any chance of leakage whatever and wherein the balancing of the steam-regulating valve is very simply provided for and whereby the cutting off of steam when the latter valve is closed, thereby instantly effecting the closing of the checkvalve, is instant and automatic, as will be readily understood.

Having thus fully described our invention, We claim 1. In a valve, the combination of a steam admitting and regulating valve, exteriorly controlled, and a check-valve positively operated by the movement of the stem of said first-mentioned valve when opened, substantially as described.

' 2. In a valve, the combination of a steam admitting and regulating valve, exteriorly controlled, a cam carried by said valve-operating stem, and a check-valve operated for opening by the movement of the stem of said first-mentioned valve, substantially as described.

3. In a valve, the combination of a steam admitting and regulating valve, exteriorly controlled, a cam carried by said valve-operating stem, a ball check-valve with a pivoted lever between it and the aforesaid cam for imparting motion upwardly to the checkvalve from the first-mentioned valve substan tially as described. 7
