J'EITS A. PAASCHE, OF CHICAGO, ILLINOIS.
REGULATOR.
Specification of Letters Patent.
Patented Dec. '7, 1915.
Application filed May 9, 1910. Serial No. 560,328.
Toall whom it may concern:
Be it-knwn that I, JENs A. PAASCHE, a
citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have" invented certain new and useful Improvements in Regulators, of which the following is a specification.
This invention relates to electric regulators which are-adapted to maintain a sub-.
' which is simple, durable, and e cient in opstantiallv'uniform fluid pressure in a tank or the like by controlling the means delivering to the 'tank.
The invention comprises. means movable by the pressure within the tank and devices controlled by said means to start and stop the pump delivering tosaid tank, as for in,- stance, by opening and closing a switch for an electric motor driving the pump.
The primary object of the invention is to produce a regulator of the ty e described pump or other eration .in any position, whether vertical,
' horizontal or otherwise.
It is also'an object to provide means in a regulator for opening and closing an electric switch or the like quickly.
In the accompanying drawings, Figure 1 is a side elevation, party in section, of a regulator embodyingthe features of my invention. Fig. 2 is a top plan view. Fig.
3 is a fragmental detail of the connection between the operating levers. Fig.4 is a sectional view illustrating the electric switch.
In the embodiment herein shown of my invention, A isa tank adapted to contain pressure fluid, and B is a pipe leading into the tank, said pipe having a cock C therein arranged to control the flow of fluid throughthe pipe. The outer end of the pipe B may be connected with a pump (not shown) to deliver fluid to the tank A.
A diaphragm casing 1 having a diaphragm 2 therein communicates at one side of the diaphragm with the tank A in any suitable way. In'the present instance said casing is supported upon the pipe B and the loweir half' of the casing e. the space beneath the diaphragm, communicates with said pipe. A plunger 3 is slidablymounted in the upper wall of the casing 1, said plunger having a head a which rests upon the diaphragm 2. Two oppositely extending levers 5"fll1d 6 are pivotally mounted near the1r ends upon a lug 7 on the upper wall of the casing 1, the inner ends 5' 6 of said levers, in this instance, being forked, as
shown in Fig. 2, to lie at opposite sides of said lug.
.In the present embodiment, l. the end of the fork 6 is widened as .at 8 to inclose the end of the fork 5 and said ends are pivotally connected together by means of pivot pins 9 extending through openings 10 in the fork 6 and secured in the fork 5 The openings .lO are larger than the pins 9 to provide a Slight amount of lost motion between the two levers 5v and 6 for a purpose to appear hereinafter.
An arm 11 on thecasing 1 extends outwardly beneath the lever 5 and carries at its outer end a pair of long parallel electric spring contact arms 12, said arms being insulated from each other. If desired, one of the arms 12 may be longer than the other. A suitable contact device such as a sleeve 13 is carried at the outer end of the lever 5 anclis insulated from said lever, said sleeve preferably sliding in contact with the longer one of the arms 12 and moving into and out of contact with the shorter arm, when the lever 5 is swung on its pivot so as to make and break electrical connection between said arms.
Normally the lever 5 is held down, so as to keep the switch 12 13 closed, by'means to be now described. A coiled spring 15 is attached at one end to a suitable stationary part, such as the pipe B, and at its other end to a threaded pin 16 which extends through an opening in the lever 6, a nut 17 being turned upon said pin above the lever 6 so that the tension of the spring 15 may be adjusted. Said spring tends to hold the lever 6 down and owing to the connection between the levers 5 and 6, t e lever 5 is also held down. r
The lever 6 is arranged to beengaged by the plunger 3 for moving said lever upwardly.
18 is an antifriction roller carried by the lever 6 in position to be engaged by the plungen V As s commonly understood, it is desirable to open and close aneleotric switch Quickly so as to prevent arcing; a To accomplish this result I have prov ded, in this 1nstance, the
following means. Pairs of ears 19 upon the levers 5vand 6, respectively, are csnnected together by means of links 21, said links i'g' being coiled a portion of their length t'o' form springs .22, 'From' an inspection of Fig. 1 itj'willbe seen that when the lever 6 is'moved upwardly by the plunger 3 to carry the resilient connecting links 21 slightly 5 above the ".dead center for the lever 5, said connecting links 21 will quickly snap the lever 5 upwardly and open the switch 12 15, the upward movement of-isaidlever v5 being limited by the stops 1 1, Similarly-when'the 6 links 21 are carr edbelow said dead centei ithe lever 5 will be snapped downwardly t'o quickly'closeflthe, switch 12 13. vIt is obvious that a slight movement of theplun'ger 3" will synchronously cau e a considerably 25 greater movement'of the ears 20; i
switch before the said lever 5' is given any 3o gradual preliminary movement, but jif the pin 9 fits more closely, the lever willbegin to move gradually 'soon aft' lower .6 starts and'they willso continuf I v unison until the ,dead center is reached, when the former will be snapped-quickly. The
adjustment or rather the relative size of pin 9 may be such that lever -5 willstart at substantially the same timer with lever 6., in
, .which case aslightmovement'of plunger 3' 40 will cause-a 'relat'ivelygreater movement of t ears 19 and 20;,
In the initial upwardmovement 5f the lever 6 the 1 veaaiwni not'ordinarily 'be affected; Continuingmovement of said lever 6, howevenwill bring the wall of the open:
ing, 10 into engagement with the pin 9 C31? ried by. lever=5.' .Said lever 5 will then be.
' moved a short distance by. the lever 6,'"until the links 21 pass over dead center when thelever 5 will be snapped to its limit of lever 5 starts to move and the farther it" turns before the dead center is reached, the less will lever 6 have to be turned before the critical point or dead center is reached.
The contact springs 12 are adjusted in length and' position so that lever 5 can oscillate In case the pin 9 fits very loosely the lever ,fi'fnay be moved far enough to cause the spring 22 Ito snap lever 5 and actuate the driving the .pump.
including a pair of oppositely extending and through a considerable angle withoui- 13:;311-
ing the switch.
Ad iiStHlBDii at the pivot 9 'determlnes the degree of sensitivenessor the necessary amount of change In pressure, whlle adJust- 70.
ment of spring 15 determines theabsolute pressure at which the switchshall operate. Obviously there must always be .a' certain amount of longitudinal clearance I for the pivot 9 in opening 10 due to the varying triangular relationof the pivot 9 to the stationary pivots on lug 7. o
The movements of the lever6 are steady,
the upwardmovement of said} lever being.
caused .by' thefplunger 3 resisted by the spring 15, and the downward movement thereof being caused by said spring 15.- The loose connection between the ends of the levers 56, caused by the difference in the sizes of the pivot pins 9 and the openings 10,
permits the lever 5 to-be suddenly moved or snapped when the line of pull of the links 21 passes dead center sothat the switch 12 13 will be quickly opened'and closed.
. In operation, assuming the switch 12 13 to be closed asishown in Fig. l, the pump is driven to force pressure fluid into the tank A until the pressure against the diaphragm l is sufficient to raise the lever 6 against the tensien of'the spring 15. When the said lever '-is thus raised sufiicientlyxto carry the links 21 above'the pivotalcenter for the lever 5,
. said lever 5 will be snapped upwardly and the switch 12 13 opened to stop the motor When. the pressure in. the tank falls, the diaphragm 2 and plunger 3' will sink, permitting the spring 15 to switch 12' 13 as above described.
I am aware that minor changes in the construction of the present embodiment may be made without departing from the invention,
I draw the'lever 6 downwardly and closethe therefore, I do not limit myself to the exact details herein shown 'and described.
