PORTABLE DISPENSING DEVICE.

Application filed April 12, 1922. Serial No. 551,812.

To all 'ZIU/IOIII, it may concern:

lie it known that 1, CHARLES SrAn'rn, a

citizen of the United States, residing at Cleveland, in 'the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in a. Portable Dis pensing Device, of which the following is a specification.

This invention relates to dispensing de- .vices for lubricating oils, and has for an object to provide a portable container with a pump adapted to deliver accurately measured quantities of oil, a further object is to provide means for holding said container against movement during operation of the pump. A further object isto enclose the piston rod. in a closed housinp to eliminate oil leakage. Other objects will be apparent from the following description in connection with the annexed drawings.

In said annexed drawings:

Fig. 1 is a side elevation showing the devicein use for filling an. automobile transmission case.

Fig. 2 is a top plan view of the device.

Fig. 3 is a broken vertical section showing the container in section and a portion of the pump in side elevation and a portion thereof in section.

Fig. 4 is a broken vertical section taken at right angles to the section shown in Fig. 3.

Fig. 5 is a section on line 5-5 of Fig. 3.

Fig. 6 is a perspective view of a modification. 7

\ Referring to the drawing-a cylindrical sheet metal container 1 is provided with top 2 having, a filling opening 3 therein closed by a detach able cover l and an opening 5 at one side of the opening 3 in which fits a vortically disposed pump cylinder 6 supported on a flange 7 engaging' the top of the container about the opening 5 and bolted thereto.

The cylinder 6 has a closure plug 8 in the bottom thereof which has a countorbore S) on the under side thereof tapped to receive the upper end of an intake conduit 10 which extendsdownwardlv to adjacent the bottom of the receptacle, and perforations 11 through which the conduit 11) communicates with the interior of the receptacle.

A check valve 12 normally seated by gravityupon the upper side oi the plug" 1) prevents escape of oil through the perforations v1.1 on the down stroke of the plunger. A

piston 13 is movable vertically within the cylinder 6 and has a piston rod 14 fixed:

thereto and extending upwardly and openlugs 15 therein to permit oil toflow therethrongh'on the down stroke, thereof. A. check valve 16 is slidably mounted on the rod 15 above the piston 13 and is normally ,7 held seated upon the piston over, the openingrs 15 by a coil spring 17. An outlet conduit 18 communicates with the upper end of the pump cylinder 6 above the top of the receptacle 1. The cylindrical piston rod 14 has rack teeth 19 formed between parallel transverse notches in one sideof the rod. A transverse shaft 20 is journaled in the upper end of the cylinder 6 and has a pinion 21 within the cylinder meshing with theteeth 19 on the piston rod. A'crank 22 is fixed to the outer end of the shaft 20. An extension ill housing 23 is secured to the top of cylinder 6 enclosing the upper end of the piston rod 14. A set screw 24 in the upper end of the housing 23 forms an adjustable limit stop for the piston 13. An angle foot plate 2.5

I is secured to the wall of the container at the bottom thereof by means of which the operator can hold the container against movement during operation of the pump.

In operation the crank 22 is turnedto raisethe piston 13 until the rod 14 engages the set screw 24. During the upward movement of the piston 13 oil is drawn through the inlet conduit 10 past the check valve 12 into the cylinder 6 filling the portion of the cylinder beneath the piston 13. By properly set-ting the stop member 24-the exact amount of oil desired can be drawn into the cylinder 6. Thecrank 22 is then rotated in a reverse direction until the piston 13 is seated upon the bottom of the cylinder 6. During the downward movement of the pump, the check i alve 16 is forced upwardly against the actioh of the spring 17 and the oil lows throhgh the openings 15 in the piston 13. raise the piston 13 until the rod 14.- again strikes the limit stop 24. During upward movement of the piston 13 the valve 16 is held sealed by the pressure of the oil and the oil above the piston 13 is discharged from the cylinder (5 through the discharge conduit 18. By housing the piston rod 1 1 in an extens n of the pump cylinder it is not necessary to provide a packed tight fit The crank 22 is then rotated to oo of the cylinder and leakage of oil is elimiquantities less than a full hated. The pinion 21 and rack teeth 19 are preferably so proportioned that for each 7 revolution of the crank22 a certain unit volume of oil is discharged so that measured cylinder' charge may be delivered through the outlet conduit 18 y turning the crank 22 through the desired number of revolutions.

" The container is made of relatively thin sheet metal, including the top 3, and a metal stifi'ening bar 26 is fastened diametrically across the bottom face of this top intermediate openings 3 and 5 where one of the fastening bolts 27 ,for the pump may pass through the bar, and unite the parts together. Thus bar 26 sustains the Weight of the pump, the strains in action, and permits the entire container when loaded to be carried bodily by gripping column 23 Without danger of buckling or damaging the thin-top 2 of the container. In Fig. 6, a skeleton frame. 28 is provided for container 1 comprising a base ring 29 upon which the foot may rest to hold the container stationary when turning the crank.

of the operator What I ciaim,.;s:

1. A dispensing device for oils and greases, comprising a sheet metal container having a pump body extending downwardly through its top, lugs extending from the mated upon said top, a cylindrical extension tor said body exposed above said top, operating means within said body having a crank outside said container, and a rigid bar extending across said top within said container support for said pump, and means uniting one of said lugs and bar and top rigidly together.

2. A dispensing device, comprising a portable receptacle having a sheet metal top, a pump cylinder suspended from the top of said container having liftpump mechanism therein, a crank at one side of said container providing a supplemental adapted'to operate said pump mechanism, a I

re-enforcing member for said sheet metal top, and fastening means for said pump cylinder connected with said re-enforcing member. In testimony whereof I afii r my signature to this specification.
