LINNAEUS E. BAKER, OF FOB/'1 WAYNE. INDIANA, ASSIGNOR TO WAYNE TANK & PUMP COIvEPANY, OF FORT WAYNE, INDIANA, A CORPORATION OF INDIANA.
STOP MECHANISM.
Application filed October 10, 1922. Serial No. 593,570.
To (all whom it may 0011 cera- Be it known that I, LTNNAEUS E. BAKE-R, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful ln'mrovements in Stop Mechanisms, of which the following is a specification.
My invention relates to combinations of machine elements constituting stop mechanisms, such as dispensing apparatus used for gasoline or oil and particularly to means for limiting the movement of the pump piston or othersuitable moving part to insure discharge of the quantity of liquid desired to be dispensed at that pumpingv The invention consists oi": a new combina tion of stop rod and stops thereon and is characterized by few and simple parts and ease of manipulation.
, he object of the invention is to throw into acting position any of the stops desired, by simply giving that stop a partial rotation instead of first rotating another stop or other steps out of position and then rotate the desired stop into position.
Another object of the invention is to conserve space by using only a limited segmental space, instead of circling entirely arpund the stop rod.
The particular embodiment oi? my inven tion selected for illustration is a measuring pump or" the rack and pinion type, adapted o dispense liquid on the up stroke of the iston.
Figure 1. is such a measuring pump shown in side elevation, a part of the gear casing being in ion, with my improved stop roe and stops in position, set to pump two units or measure, the mechanism being broken away just below the top cylind r head.
Fig. 2, a detail, is a vertical section on the line 2-2 of Fig. 1.
3, a detail, is a perspective of the upper part of the stop mechanism.
Fig. 4. is a cross section on the line 4-4 of Fig. 2.
Fig. 5, is a cross section on the line 5-5 of Fig. 2.
Referring now to the drawings, G, is the gear rack fixed to the piston rod, P, for reciprocating the pump piston. A projecting lug, g. on the rack G, extends toward the stop rod, R, far enough to be in contact with one of the stops, S, and arrest the motion of the rack, when said stop is set in using position like the three upper ones in Fig. 1, and the .rack is-then raised by operating the pump. Obviously only the lowermost of the stops in using position will be engaged by the lug, y; but it is a peculiar ity of the mechanism of this invention that whichever of the stops is set in using position. all the stops about it are simultaneously and by the one motion of setting, thrown into like position. Likewise when eve any stop is swung out of using position, all the stops below it are simultaneously and by the one motion thrown out of using position.
The rod, R, is fixed in substantially vertical. position and the stops, S, are rotatively seated thereon one above another, either abutting as shown in the drawings or with spacing washers between.
Under each stop, S, are two recesses, r, usually formed by spotting with a drill, or of course the rod could have two longitudinal slots. In either of these recesses, a", a steel ball, 8, seats under pressure of the spring, 8 One recess is so placed as to keep the stop in position when aligned for contact with the stop lug, g, and the other to keep the stop out of contacting position with the lug, 9, when not set for use.
Each stop has a handle, 8' for convenience in rotating it into and out of us ing position.
Each stop is drilled on the front or projecting end, 8 parallel with the rod R, and threaded to receive a set screw, 5, and the head of this set screw is drilled, at s, to receive a sealing wire, 3. Above the projecting end, 8 is a fin, s, pierced by a hole, .9 to receive the sealing wire, 8, and on its under side is a downwardly projecting lug, 8 adapted to contact with the fin, s, of the next lower stop, S, when their projections, 8 are in alignment. A similar lug, 7a, is also provided on the housing H, for the topmost stop and another, 721 for the bottom. A seal, 8 is used in the ordinary manner after the set screw, 8 has been adjusted to proper measuring position.
An adjustable set screw, 5 with seal guard, if, is adapted to determine the maximum pumping stroke of the piston, by con tact of the lug, g, therewith when all the swinging stops are rotated out of using position.
Numbers may be provided on the stops or on an adjacent part of the housing opposite each stop, to indicate the gallons or other units of measure the pump is set to dispense, when said stop is brought 'into engaging position with the lug on the rack.
Obviously many changes may be made in the device. herein shown, to suit the various types of dispensing mechanism, without departing from the spiritof my invention. 7 V
I claim as my invention and desire to secure by Letters Patent of the United States:
1. A shaft with a plurality of machine elements longitudinally mounted thereon and adapted to be rotated a part. rotation and means on said elements adapted by the forward rotation of any of said elements to insure the forward rotation of all elements on one side of the positively rotated element not already in the forward position, and means on said elements adapted by the backward rotation of any of said elements to insure the. backward rotation. of all elements on the other side ofthe positively rotated element not already in the said backward position.
2. In combination with a moving part of a dispensing apparatus; a quantity stop rod substantially parallel with said moving part; a plurality" of stops on said rodyand means on said stops for producing the simultaneous rotation into using alignment of all stops out of using alignment on one end of the one so rotated, by such rotation of the one for use; and means for producing the simultaneous rotation out of using alignment of all stops not already out of using alignment on the other end of any one so rotated by such rotation.
3. In combination wit-h a projection on the reciprocable operating means of a measuring pump; a quantity stop rod substantially parallel with said operating means;
a plurality of stops on said rod, and means 1 on said stops for producing the simultaneous rotation into using alignment of all stops out of using alignment above the one. so rotated, by such rotation of the one for use; and means for producing the simultaneous rotation out of using alignment of all stops not already out of using alignment below any one so rotated by such rotation.
' In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
