JOSEPH P. LAVIGNE, OF DETROIT, MICHIGAN, ASSIGNOR TO THE LAVIGNE MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A' CORPORATION OF MICHIGAN;

PUMP.

To all whom it Ma concern:

Be it known that'I, JosEPH P. LAvIeNE, a citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certainnew and useful Improvement in Pumps; and I declare the following to be a full, clear, and exact description of the same, such as will enable others Skilled in the art to .which it pertains to make and use the same, reference beinghad' to the accompanying drawings, which form apart of this specification. v v

This invention relates to pumps; it has for its object an improved pump of which the character intended to be used for furnishing -a regular and constant supply of oil to machinery to be lubricated. The usefulness of the pump is'not, however, intended to be limitedto this purpose.

In the drawings :Figure 1, is an elevation showing two individuals of a battery of pumps submerged in a tank; the tank is shown in section and one of the piston guides is shown in section.- Some other parts of the driving mechanism are also in section. Fig. 2, is an elevation of a pump piston. Fig. 3, is an end view of the pumppiston. Fig. 4, is an elevation of a guide and indicator.

1, indicates the case of a tank in which the pumps are submerged; in the structure thereare assembled several pumps, two of which are shown in the drawing and a description of a single one will suffice for an understanding of all.

2, indicates a casing which includes a pump barrel and a valve shell; 3, indicates an oscillating valve actuated by lever 4, which is pivotally connected to a reciprocating driving rod '5; this driving rod 5 is actuated by cam 6 and a' similar cam at the opposite endv of the shaft 7 (the second cam is not shown). rel 2, and is driven in its reciprocatin Ino' Apiston 8 reciprocates in the bartion by a cross'beam 9 which, itself, is re-' eiproca-ted by acrankarm 1Q pivoted to crank pin 1'1 on the face of a driving wheel Specification of Letters Patent.

12. The driving wheel 12 is a worm wheel driven by worm 13 from any convenient source of motion. The beam 9 engages on a prismatic portion 14 of the piston stem and engages between a collar 15 that is fixed with respect to 'the piston, and a sleeve 16 that is adjustable with reference to the pistonqThe portion of the stem above the prismatic section 14 has a threaded section v 17 with which the sleeve engages, and the sleeve is interiorly-threaded in order that it may be adjustable along the threaded portion-17 of the piston stem. Thesleeve is also split and'engages tightly by resilient compression against the threaded part of the stem. The sleeve reciprocates through an opening 18 in the case and at its upper end is formed with aprismatic portion 19 to furnish a wrench hold, and above the-prismatic portion is a graduated collar 20. The position of the sleeveon the stem is' indicated by these graduations, which act in conjunction with ring graduations 21 on the pistonstem to indicate the relative position of the sleeve and the iston, and u on this relative position oft e sleeve on the iston-depends the travel of the pistonpro uced by the cross beam 9. The graduations on the collar 20 indicate portions of a revolution of a sleeve 16 relative to the piston stem and the ring graduations 21 indicate the number of. such revolutions.

In operation, the cam 6 timed with reference to the wrist pin '11 to open the conduit controlled by valve 3' during that period of the upstroke of the piston which follows the engagement between the cross beam 9 and the s eeve l6 and to close the valve 3 as the cross beam begins to descend, and to openthe conduit for the 'discharge of the oil from the pump barrel just prior to the time of contact between the cross beam and collar 15 and to keep the dischar e open during the period which follows the first contact of the cross beam 9 With'the collar 15 on its down stroke. The length of the stroke of the piston which determines the amount of dis-' charge at.each impulse is regulated by the position of the sleeve 16 on the piston stem. As shown in the drawin the sleeve 16 is turned entirely down on t e piston stem .and the piston in this position 'with reference to the sleeve will produceits maximum stroke and a maximum flow ofoil. l

.Yhat I claim is 1. In a pump, the combination of a pump barrel, a piston reciprocating therein", a stem for said piston provided with a prismatic .for actuating said piston, and means whereby the relative position of said sleeve and stem determines the travel of the piston sub stantially as described.

2. The combination of 'a tank, a uinp inclosed therein provided with a arrel, a piston and a stem therefor extending through a wall of said tank. provided with a prismatic section and with a graduatedterminal, a cross-head fitting, upon said prismatic sec tion and adapted to slide thereupon, means for reciprocating said cross-head, a sleeve adjustable along said piston stem and extending through the wall of said tank and provided with a graduated terminal adapted to coact with the graduated-terminal of the stem to indicate the travel of said stem,

and means whereby the relative position of said sleeve and stem determines the travel of the piston, substantially as described.

3. The combination of a tank, a pump inclosed' therein, said pump being provided with a piston and stem jtherefor, vsaid stem extending through a wall of the tank, a sleeve surrounding said stem passing, and adapted to reciprocate throu h, the wall of said tank, said sleeve being adjustable along said stern, and means whereby the relative position of said sleeve and stem determines.

the extent of travel of the piston.

In testimony whereof, I sign this specification in the presence of two Witnesses.
