Specification of Letters Patent.
Patented Feb. 5, 1907.
Application filed March 15, 1906. Serial No. 306,311.
To all whom it may concern:
Be it known that I, Ax'rox C. Soma- MANN, a resident of Decatur, in the county of Macon and State of Illinois, have invented a certain new and useful Compression Stop and Waste, of which the following is a specification.
The invention is applicable to stop and waste cocks or faucets to hydrants and to other appliances that act on the stop and waste princi le.
The principal object of the invention is to avoid ope v the two valves of a compression stop an waste at the same time, thus precluding the possibilitv of water or other fluid bein forced through the waste by pressure on t e fluid; and another object is to insure the operation of the invention as an ordinary stop and waste in case the spring that prevents the opening of both valves at once should become broken.
The invention is exemplified in the structure hereinafter described, and it is defined in the appended claims.
In the drawings forming part of this specification, Figure l is a central section lengthwise of a sto and waste in which my invention is embodied, the main valve be shown open and the wmtevalve closed. ig.-2 is a cross-section on line min Fig. 1. Fig. 3 is a central section lengthwise of the cock, showing both valves closed; and F' 4 is a similar section showing the waste-v ve open and the main valve closed.
The body 1 of the cock has a valve-seat 2 and a cylindrical extension 3 in axial alinementaith the valve-seat. A bonnet 4 is secured to extension 3 by means of a unionnut 5, and it has an internal shoulder 4",
ainst which the waste-valve collar bears w en the waste-valve is wide open. A packing-nut 6 is screwed onto the upper end of bonnet 4, and pac 7 is interposed between the nut 6 and the bonnet. A valvestem 8 extends through cap 6, paclnng 7, bonnet 4, and it is screw-threaded on its lower end to enter the internallv-screw-threaded valve-plunger 14. A handle 9 is secured to the upper end of the valve-stem, and a valvecollar 10 is formed on the stem between its ends. A valve-seat ring 12 is provided with a flange that is held between the bonnet 4 and the body extension 3, and a valve-seat 12 is formed on the upper surface of the valve-seat ring. The valve-collar 10 has a downward-presented annular recess, and a valve-ring 11 is held in the collar in position to close against seat 12.
The body extension 3 has a plurality of internal lengthwise grooves, preferably four, as shown at 3 in Fig. 2, and the valve-plunger has a less number of ribs 15, preferably two, which slide in grooves 3 and prevent the plunger from t A valve-disk 16 is held in the lower end of plunger 14 by means of a screw 17, a waste-pipe l9 penetrates the bonnet above valve-seat l2, and a 18 is inte osed between collar 10 an the upper end 0 the inner surface of the bonnet.
As shown in Fig. 1, the valve 11 rests on the valve-seat 12 and holds the stem from farther descent, while the screw-threads 13 are screwed into the internal threads 14 of the valve-plunger sufliciently far to raise the upper end of t e plunger against the under side of ring 12. linder these conditions the ring 12 is clamped between the valve 10 an the plunger, and the waste-valve is held securely closed, while the main valve is held positively and securely in an open ition. Vhen the main valve is open, t e fluid passes through the cock in an obvious manner.
When it is desired to close the main valve, the valvestem is turned in a direction to unscrew the stem from the plunger. The spring I8 holds the waste-valve seated. The ribs 15 move down grooves 3 and hold the pl er from turning, and the plunger dc seen until the valve-disk 16 is in contact with seat 2, as shown in Fig. 3. To open the waste-valve, the rotation of the stem is continued in a direction to unscrew the stem from the lunger. The contact of the main valve wit its seat prevents farther descent of the plunger, and so the waste-valve is raised against the action of spring 18. When the waste-valve is raised until the collar 10 contacts with shoulder 4, the main valve is held positively closed independent of the action of the spring, and the waste-valve is of course held positively opened. 'hen the waste-valve is raised from its seat, a wastepassage is established through the mob structed grooves 33 in extension 3, through valve-ring 12, and through pipe or outlet 19. In closing the waste-valve preparatory to and a collar 17, which are firmly attached to the shaft by transverse pins or otherwise. Surrounding the extension 16 is an expandmg spiral spring 18, which has its inner end abutting against the collar 17 and its forward end 19 preferably engaging an opening 20 in a The sleeve 21 in turn rests A fiber 5 friction-disk 22 is preferably located between the outer face of the hub 12 and the friction thrust-disk 10, though this latter is sleeve or ring 21. against the portion 12 of the fan.
not absolutely essential. It seems, however,
to take part of the wear and to increase the frictional contact of the front end of. the hub in respect to the coacting friction-disk 10.
In operation the engine is started'as usual Usuallya start-ingin any suitable manner. crank, such as 23, is provided for that purpose, though other means of starting may be utilized. As stated, an explosive-engine starts suddenly, and the fan being-fiicti'onally I held on its shaft by the means here shown 5 and described the sudden shock to the-gearing is relieved. Also explosive engines when-running are frequently suddenly speeded to a veryhigh speed. In such event the shock to the fan-gearing is relieved for the moment bythe ction arr ement; .but the fiicticfmal drive will grsildua y take hgld until the anis runnin a at t eproper spee Attention-is directedto thefact that the driving frictional surfacesare so arranged that theair-pressure upon the blades of the g fan will cause a frictional thrust in addition J to that caused by the expan -spring 18.
This tends to cause the fiictiona contact to be increased when required for high speed,
but is of such extent as to permit the fan to slip welzfn tne engine is started or suddenly 4 Speed The construction here shown and described is found to embody'a rinciple of operation that isfound exceeding 3' efiicient and to peri mit the use of the desirable gear-driven fan without its recognized disadvantages, heretofore pointed out.
Having thus described our invention. what we claim, and desire to secure by Letters Pati cut, is
1. The combination with an explosive-engine, of a fan-shaft, gears positively connecting the engine with the fan-shaft, a fan loose on the fan-shaft, a friction-disk fast on the fan-shaft and coacting with the fan-hub for driving the fan, an expanding-spring having one end coacting with the opposite side of the hub from the said friction-disk, and the opposite end of the spring held by a shoulder on the fan-shaft, the parts cooperating as described.
2. The combination with an explosive-enf gine, of a fan-shaft,gears. positively connecting an elongated hub loose on theshaft, a friction-disk fast on the shaftand cooperating with one side of the hub for driving the fan, and an expandin -spring cooperating with the opposite side of the hub for the-purpose described.
3. The combination of a fan-shaft, means for driving it at different speeds, a fan loose f on the shaft, friction devices between the fan and its shaft for driving it, the friction devices so located that the air resistance upon the blades of the fan causes the friction to increase or decrease according to the speed of the fan.
4. The combination-of a fan-shaft, means for driving the shaft at different speeds, a fan loose upon the shaft, friction driving de- .vices between the shaft and the fan, means forcing the friction devices together, the friction devices being so arranged that the air resistance to the blades of the fan will add to the frictional engagement of the friction driving devices when the speed of the fan is increased.
