T 0 all whom it may concern:

Be it known that I, JOHN B. COLLIN, of Al- 'toona, county of Blair, and State of Pennsylstand-pipe; and, second, in the combination,

with the valve, of certain mechanism for operating the same, the latter being adapted, by means of its construction and location, to be conveniently actuated by the fireman without getting oft" the tender.

It consists, further, in certain other co1nbinations and in certain details of construction, all of which will be fully described hereinafter.

b and b represent the bearing-seats of the valve-openings in theotherwise closed end of portion b.

1) represents a removable cover adapted to close the openingin the outer portion, b, which is provided with a stuffing-box, b otordinary construction, as shown. By means of the described construction a water-space is caused to entirely surround the projecting inner portion, b, as shown in Fig. 6.

b, Fig. 7,representsa hollow cylinder bolted to the lower side of theportion b of the pipesection B, which is open above, as shown, and isadapted in size and positionto extend into the recess b of the valve, as shown in Fig. 6.

my improved stand-pipe, I will proceed to do Ioo b represents the lower disk of this valve, which is adapted to fit the seat 12 and b the recess before referred to.

12 represents the upper disk of the valve, which is adapted to fit the seat b and is provided with the guiding-wings b as shown.

I), Fig. 6, represents the valve-stem, secured at its lower end to the valve in any proper manner, and provided above with a copper tube or pipe, b, as shown, bymeans of which pipe a better protection is afforded against rust.

I), Figs. 6, 10, and 11, represents a crossbar held by the levers a by means of which the valve-stem b is united to the levers.

b, Figs. 4. and 12,represents a tube extending from the pipe-section B, which opens into a cylinder or cock, I), having an opening, I), as shown.

1) represents a hollow plug within the cylinder, which is provided with oppositely-located openings, as shown.

' 21 represents a lever-arm, by means of which the plug may be revolved when desired, and I1 a connecting-rod uniting the leverarm 12 to one of the lever-arms c, as shown in Fig. 4.

C, Fig. 6, represents the curved pipe-section before referred to, the outer end of which is united to section B and the inner end to section D, as shown.

0 represents an enlargement upon the vertical position of the pipe-section, which is provided at the base of its interior chamberwith a semi-spherical recess adapted to hold the brass balls 0 c, as shown.

D represents a vertical pipe-section having at its lower end a bearing-flange, (1, adapted to rest upon the balls and sustain the inovin g portion of the'stand-pipe.

(1 represents a packing-ring, by means of which packing may be applied to the pipe at this point to make a water-tight joint.

E, Figs. 5 and 6, represents a vertical pipesection extending from the upper end of section D to the lower end of the curved upper section, F, as shown, which section is provided with an overhanging flange, e, as shown in Fig. 1.

0 represents a conical section or base-piece bolted to the platform of the stand-pipe, the upper edge of which projects into the recess of the flange e for the purpose of maintaining the stand-pipe in its proper vertical position.

0 Figs. 5 and 6, represents a sleeve or collar upon the pipe E, which is capable of free movement in a vertical direction, and 6 6 parallel rods, the lower ends of which are attached to the collars in any proper manner, and the upper ends of which extend upward through the adjacent flanges of the pipe-sections E F to the rods ff upon the pipe-section F, as shown in Figs. 1 and 3.

e 6 represent horizontal levers, the rear ends of which are supported by the cross-bar a before referred to, and the front ends of which are held between the flanges of the collar 6 as shown in Fig. 6.

f, Figs. 1 and 3, represents the transverse shaft of a bell-crank lever, held by proper bearings on the pipe-section F, which is provided with the single central arm,f and the two side arms,f f as shown. r

f represents a horizontal arm extending from the pipe-section F, upon which is located the adjustable connterbalance-weight f as shown.

G represents a pipe-section extending forward in a horizontal plane from the upper end of the curved section F, which is provided with a curved discharge end, 9, as shown.

H represents a. bell crank lever held by proper hearings on the front end of pipe-section G, the short arm h of which is united by means of the connecting-rod h to the long arm f of the bell-crank lever on pipe-section'F.

The operation of the described construction is substantially as follows: Vthen it is desired to use the stand-pipe the horizontal arm of the same is swung over the tenderin the manner well understood, the moving part of the stand-pipe turning readily on the friction-balls c 0. The actuating-lever His then moved by the fireman from its normal position (shown in Fig. 3) to the position shown in Fig. 9. By means of this action the valve is opened, as shown in dotted lines, Fig. 6, andfull lines, Fig. 7, through the intermediate mechanism described, and the water consequently is permitted to flow from the main through the stand-pipe and out into the tender. When the proper supply has been obtained the lever H is moved back again to its normal position (shown in Fig. 3) to close the valve and stop the flow. \Vhen the actuating-lever H is in the position shown in Fig. 9 it is locked against an accidental return movement, the connecting-point of the lever being practically behind the base of resistance, so that movement cannot occur until the same has been lifted vertically. When the actuating-lever is moved to open the valve the first portion of its action moves the adjacent end of the con-. necting-rod h more in a vertical direction than in a horizontal, and the subsequent portion .of its action moves the connecting-rod more in a horizontal direction than in a vertical. From this it follows that the valve will be opened slowly in starting and more quickly afterward. The person also who aetnates the lever uses his power more effectively in starting the valve from its seat. The movement of the valve also in returning to its seat is eased by the action of the cylinder 1;, which compels gradual movement by the gradual escape of the water contained therein through the loose fitting joint. the safety-valve all injury from shock is avoided when the valve is closed. The main valve, it will be observed, is balanced, so that no great By the employment of this. device and.

IIO

resistance to movement exists. The same ac tion that closes the main valve opens the waste-cock, so that the water shut into the stand-pipe is permitted to escape.

Some of the advantages of the described construction are as follows: By the employment of the cylinder b the movement of the valve is arrested in closing for the purpose of preventing -sudden shock. By means of the special construction of the actuating mechanism the valve is readilymoved from its seat, and when moved is automatically held in its open position. By means of the special location of the valve it may be readily reached without dismounting any portion of the structure.

Having thus fully described my invention,

what I claim as new,'and desire to secure by Letters Patent, is

1. In combination with the valve having the 20 recess b the loose-fitting cylinder b and the valve-seat b substantially as and for the purpose described.

2. In combination with the rock-shaft f and the connectionsf and h, the lifting-rods 25 f, substantially as described,adapted to swing past the center, as shown in Fig. 9, for the purpose of locking the valve.

This specification signed and witnessed this 20th day of May, 1882.
