SEECIFICATION forming part of Letters Patent No. 687,409, datedll'ovember 26, 1901.
Serial No. 57,485. (No model.)
To aZZ whom it may concern: 7
Be it known that I, FRANZ SEIFFERT, asubject of the Kingof Prussia, German Emperor, and a resident of 154. Koepenickerstrasse, Berlin, Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Out-01f Valves,of which the following is an exact specification.
My invention relates to improvements in cut-off valves for steam, air, water, and the like pipes.
The object of my invention is to avoid the spindle for moving the valve-slide having to be tightened'by means of a stuffing-box or the like. I attain this object by the construction illustrated in the accompanying drawings, in which similar letters denote similar parts throughout the different views, and in Which- Figure 1 is a vertical section of the valve. Fig. 2 is a vertical section at right angles to that shown in Fig.1. Fig. 3 is partly an upper view and-partly a horizontal section of the valve. Fig. 4 is a side view of a modification of the construction shown in Figs. 1' to 3. Fig. 5 is a vertical-section of this modification. Fig. 6 is a horizontal section of the same.
In the construction shown in Figs. 1 to 3, a. is the valve-case, which is divided in two of this cross-wall slides c and d are situated. These slides c and d are provided with noses c and cl, by means of which they are fixed to the square 6 of the spindle f. This spindle f can be moved by means of the hand-wheel g. The cross-wall Z2 is in its lower part provided with several perforations or slots h, which perforations correspond with perforations 1i and k of the slides c and d. In the upper part of the cross-wall a slot Z is provided for taking up the noses c and d of the slides. The spindle f is guided in the cross-wall I).
cover the slot Z of the crosswall-that is to say, to cover this slot as'well in the position in which the perforations or slots h are open as in the position in which they are closedso that the steam, water, or the like contained in the valve cannot escape through the bore for the spindle f. The necessity of a stuffingbox for tightening the spindle is therefore perfectly avoided.
The modification shown in Figs. 4 to 6 differs from the construction shown in Figs. 1 to 3 by the slides c and d not being moved up and down. In this construction turning slides c and d are provided, which turn around the fulcrum m, provided on the cross-wall b. The turning of the slides is eifected by means of the hand-wheel g, fixed to the spindle f. This spindle is provided with threads on its lower end, which is situated in a slot n of the cross-wall Z). In this slot a sliding nut 0 is provided, which is shifted up and down by turning the spindlef. To both sides of the sliding nut 0 pins or noses p are fixed, as shown in Fig. 6, which pins are situated in grooves q, provided on the inside of the slides c and cl, so that by moving the slide-nut 0 the slides c and (Z, which must follow the movement of the nut on account of the pins 1) engaging in the recesses or grooves q, are turned. Now as the slides a and (i cannot follow the upward and downward motion of the nut these slides will be turned around their fulcrums m. Now the cross-wall b, as well as the slides c and d, is provided with perforations or slots, as in the construction described above. The slots are advantageously arranged radially. Also in this construction the slides are constructed so that the slot or for taking up the sliding nut 0 is always closed by the slides, so that the steam or water contained in the valve cannot escape through the bore for the spindle f.
It will be understood that the constructions described can be modified by providing only one slide, which must be situated on that side of the cross-wall on which the water, steam, or the like enters, in order to have this slide pressed against the cross-wall by means of the water, steam or the like. It would also be possible to arrange two crosswalls and only one slide sliding between the same.
Having thus fully described the nature of this invention, what'I desire to secure by Letters Patent of the United States is- 1. In cut-off valves, the combination of a valve-case, a cross-wall for dividing the valvecasein two separate divisions, said cross-wall being provided with perforations, a valvethose of the cross-wall, a spindle for moving both valve-slides, means for transmitting the movement of the spindle to the slides, said means being situated in slots provided in the cross-wall, so as to be always covered by both valve-slides, as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRANZ SEIFFERT.
