SIRUP PUMP Filed Sept. 19. '1929 Patented Feb. 17, 1931 i UNITED f STATES FREDERICKRAHM ANDIALLEN CLIFTON PILCHER, or LOUISVILLE, KENTUCKY, as- I sIGNoRs rro PRECISION'SYVRUP PUMP COMPANY, 0F JEEPERSON COUNTY, KEN- TUCKY l srnUP PUMP Application filed september 19,1929. `serial No. 393,637. j y f Our invention relates to sirup pumps in which the delivery piston moves a fraction of the plungers movement by means of which the piston is actuated.
An object of the invention is to provide a sirup pump which is simple in construction and easy stroking operation and will permit an adjustment in the piston displacement.
In the appended drawing, Figure 1 is a horizontal section on line 1-1, Figure 2.
Figure 2 is a vertical' section on line 2-,-2, Figure 1, and v .Figure 3 is a fragmentary elevationof the lazy tong structure as seen on line 3-3, Figure 2.
Referring to the iigures, 5 is the cylinder, the bottom 6 ofA which vis providedV with a gravitationally operable inlet Avalve 7. The.
open top of the cylinder 5 is spanned by a bridge 8 through the center of which the rod 9 of a piston 10 projects. The bridge 8 has a tubular extension 11 to one end thereof eX- tending into the cylinder through the piston. In this tubular extension a seat is formed for an outlet ball valve 12. The tubular eXtension 11 above the bridge 8 is connected to a delivery tube 13 which enters a nozzle-14 of a jar cover 15. To maintain a rigid connection between the cylinder andthe jar cover 15, a stay 16'is interposed between the cover and the bridge 8. 1 l
lIhe cover 15 has a tubular housing 17 in the central part thereof above and below the cover. The depending portion 18 of said housing is threaded exteriorly to engage a cap 19. A plunger 20,` projects through the cap and housing 17 and out through the top of the housing. The plunger 20 at the end projecting above the housing 20 carries a button 21 which has a sleeve 22 adapted to Vtelescope within vthe housing 17. A spring 23 within the housingy on the plunger normally extends the major part of the sleeve 23 out of the housing 17 thereby maintaining the end 24 of the plunger against the cap 19.
rod 91oV the lazy tongs so that theY piston travels onlya fraction of the distance of Ldie plungers displacement. l*
The walls ofthe cylinder 5to each side of tlie'bridge 8 are cut away as best shown in Figure lfto providey an opening 28 atthe top of this cylinder below the bridge 8. Thus, normally, the piston is moved out of the cylinder by the spring 23. In consequence, at vthe beginning of the pistons'imotion, there is no outflow from the cylinderuntil the piston, 10 enters ,the cylinder when the liquid enclosed in the cylinder` by 4the `piston is forcedfthrough the tubular extension 11, valve 12, delivery tube 13 and in and through the nozzle 111. Y We claim: Y
1. In a sirup pump, a cylinder open at the top, an inlet valve inthe bottom of cylinder, a` bridge above the cylinder and connected thereto, a piston in the cylinder having a rod projecting through the bridge, a tubular extension from the bridge into the cylinder through the piston, an inlet valve in said tubular extension, a cover having a nozzle, a delivery tube from the tubular eXtension to the nozzle, a stay from the cover to the bridge, a brace connecting the delivery tube to the stay, a housing on the cover, a plunger in the housing, lazy tongs connecting the plunger to the brace, links connecting the piston rod to the lazy tongs above the brace, a spring between the'housing and plunger normally moving the end of plunger connected to the tongs toward the housing and a cap adjustable on the housing engaging the said end of plunger.
2. In a sirup pump a cylinder open at the top and having an inlet valve in the bottom thereof, a bridge above the cylinder connected thereto, a piston in the cylinder having a rod projecting through the bridge, a tubular extension from the bridge into the vcylinder through the piston, an inlet valve in said tubular extension, a cover having a nozzle, a delivery tube from the tubular eX- tension to the nozzle, a plunger in the cover, collapsible means connecting the plunger to the piston rod, a spring on the plunger for normally moving the piston by the collapsible means out of the cylinder to the bridge and means for adjusting the movement of the plunger by the spring.
3. In a sirup pump, a cylinder having an inlet and an outlet valve, a piston mounted to reciprocate in the cylindeiya plunger, collaps1 ible means connecting the plunger tothe cylinder, and means connecting the collapsible means to the piston, for moving the piston in both directions. Y
In a sirup pump, a cylinder having an inlet and an outlet valve, a piston mounted to reciprocate in the cylinder, a spring actuated plunger, lazy tongs having one end thereof connected to the plunger and the other one rendered stationar and means connecting the piston to the lazy tongs between its ends.
5. In a sirup pump, a cylinder having an inlet and an outlet valve, a piston mounted to reciprocate in the cylinder, a spring actuated plunger, lazy tongs having one end thereof connected to the plunger and the other end made stationary, means connecting the piston to the tongs between the ends f thereof, and means for adjusting the plu-ngers displacement.
6. In a sirup pump, a cylinder having an inlet and an outlet valve, ya piston, a spring actuated plunger, lazy tongs connecting the plunger to the cylinder, and means connecting the lazy tongs to the piston, so that the piston will travel only through a fractional distance of the plungers displacement.
