cHARn s QGLASS, F HARTLEY, TEXAS V 011:. PUMP I Application filed July 30,

This inventionrelates to an oil pump and container especially designed for use in transferring oils such as lubricating oils, from a drum or tank, to the crank casing of an automobile v The primary object of the invention is to provide a device of this character which will transfer oil from a container to the crank casing of an automobile, eliminating any possibility of foreign matter such as dust, rain or snow, entering the oil.

- Another object of the nvention is to provide a device of thisoharacter which will facilitate the filling of crank casings by forcing the oil from the body portion of the device as distinguished from the usual method of allowing the oil to move by gravity into the crank casing.

A still further object of the invention is the provision of means for regulating the quantity of oil passing from the body portion of the device, so that the amount of oil may be accurately dispensed.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational view of an oil pump constructed in accordance with the in vention and showing the same as positioned for filling.

Figure 2 is a longitudinal sectional view through the pump.

Figure 8 is a sectional view taken'on line 33 of Figure 2.

Figure 4: is a sectional view taken on line 44 of Figure 2.

Figure 5 is an enlarged longitudinal sectional view through the pipe that is positioned in the drum or tank containing the oil. 7

pump comprises a cylindrical body portion 5 formed of translucent material, so that the operator may view the oil contained in the body portion of cylinder 5. Heads 6 and 7 respectively are positioned over the ends of the body portion 5 and fit against the gaskets 8 to provide a fluid tight connection between the ends of the body portion and theheads,

there being provided rods 9 extended the heads into close engagement -with the gaskets.

through openings in the heads for drawingiifio The reference character 10 designates-a hollow handle portion provided with a hand grip 11 at its outer end, the handle portion 10 being designed to receive the rack bar 12to which the plunger13 is secured. Cooperating with the rack bar 12 is a pinion 14: mounted on the shaft 15 that extends through the head 6, there being provided a crank handle 16 mounted on one endof the shaft 15, so that the shaft maybe rotated to move the pinion .over the rack bar 12 and cause the rack 'barto move longitudinally of the handle portion 10, resulting in a relative 1 movement of the plunger 13 toidraw liquid into the body portion 5 to fill the body portion, and force the liquid from the body portion into the crank casing to be filled. v 1

At one end of the rack bar 12 is a depending lug 17 which lug is adapted to be engagedby the sliding bolts 18 that are spring pressed and move through'openin gs in the handle 10. Bell crank levers 19 connect with the sliding bolts 18, and have connection" with grip 11, so that-the operator may bymoving the levers 21, withdraw the pins 18 to allow the rack bar 12 and plunger to move freely.= It will also be seen that due to this construction, certain of the pins may be extended in the path of travel of the lugto restrict movement of the rack 12, so that only a predetermined quantity of oil willbe dispensed- 'The' reference character 22 designates a discharge pipe to which the curved pipe 23 is connected, the curved pipe 23-having 'connection with the valve casing 24, in which the valv'e'25 moves, the va1ve 25 b in oper- 7 normal closed position. a

In order to facilitate the use of thedevice, a pipe such as indicated at 31 is positioned 1n the drum or barrel containing the 011 supply, the pipe being supplied with a fvalve to the tank upon reverse movement chamber 32 at its upper end, in Whichthe one-way valve 33 is positioned, the valve 33 acting to permit oil to be drawn through the pipe 31, but prevent the oil from returning of the plunger in thebody portion 5.

Securedto the upper end of the valve housing 32 is a union 3 1 having a curved upper surface 35 to receive the curved lower surface 36 of the valve casing 24. A vent pipe indicated at 37 has connection with the drum or supply tank, whichin the present showing is indicated by the reference letter A, the vent pipe being supplied with a cap- 38 formed withopenings to register with openings of the vent pipe, so that the cap 38 may be rotated to bring the openings thereof into alignment with the openings of the o pipe, when it is desired to remove oil from the drum or tank. The cap may be moved.

a to close the openings to prevent foreign matter from entering the tankA when oil is not being drawn from the drum or tank A.

A drain valve 39 is in communication with I claim: a In a device of the class described, a body portion, a hollow handle secured to the body portion, a rack bar operating through the handle and extending into the body portion, a depending lug at one end of the rack bar, sliding bolts extending into the hollow handle and disposedin the path of travel of the lug, for restricting movement of the rack bar, bell crank levers connected with the sliding bolts, bars connected with the bell crank levers, and levers connected with the last mentioned bars and disposed adjacent to the hande for operating the bars and sliding bolts to move certain of the bolts to allow the rack bar to move throughthe handle, a plunger on one end of the rack bar, and means for moving the rack bar through the bodypor tion. 1 I 1 In testimony that I claim the foregoing as my own, I have hereto'aifixed my signature.

the body portion and provides means where-. l i

by the contents of the body portion may be drained, should it be desired to clean the l body portion.

In the operationof the device, the valve caslng 24 is positioned on the union 34, in a manner as shown by Figure 1 of the drawings. Theilevers 21 are now operated to Withdraw pins 18 from the handle 10, whereupon the handle 16 is operated to move the plunger 13 longitudinally of the body portion 5, and towards the handle 10,drawing liquid from thedrum A into the body portion'5. V V

, It is ofcourse understood thatip'rior to the operation of the plunger as described,

the operator opens the valve 25 by exerting a pressureon the extension 29. After the body portlon 5 has been filled, the valve agaln opened and the pins 18 are withdrawn,

whereupon the handle 16 is rotated in theopposite direction to force the'liquid from the I 7 body portion 5 and into the clan I casingof a motor vehicle to be filled. I,

Should it be desired to dispense one quart 'of 011, the lever 21 connected with the first pin, or pin nearest to the gripll, is operated to move the. pin out of the path oftravel of the-lug on the rack bar-l2. v As the hande 16 is rotated to-forc'e the oil from thebody por-
