. Specification of Letters Patent.

Patented Dec. 3, 1907.

Be it known that I, CHARLES "1. TOLMAN, a citizen of the United States, residingiat New York city, in the State of New York, have invented a new and useful Graduated Measuring-Can, of which the following is a I specification. y

My invention relates to improvements in cans, -particularly to oil cans, from which a redetermined uantity ofoil may be deivered 'or supp ied to any desired point. In lubricating car journals it is generally desirable to deliver to each journal the same quantity of lubricant in order to provide uniform lubrication throughout. It is also desirable to have a can from which lubricant cannot flow by gravity until the point to which it is to be delivered shall be in communication with the reservoir, thereby pre'- venting waste of fluid and insurin the delivery of the desired amountof iuid to the desired point. Another desirable feature ina can is means for enabling the operator to rapidly handle heavy or -Slow flowing fluids to be discharged therefrom. `It is also convenient or necessary at times to deliver a fluid to a'large number of places in equal quantities, as in the use .of a liquid fertilizer or the like, where it is desirable to deliver. the same quantity of liquid to a large number ofv laces.

p My invention as for its object the provision of means for delivering from a suitable reservoir to any desired point oil 40r .other fluid' in predetermined equal quantities so Vas to' make effective,Y among others, the

various desirable features above set forth, and -to overcome the many defects now existing in cans for similar uses, and my invention consists in the novel construction, arrangement and combination of devices and parts as hereinafter more fully described and lset forth.

In the drawings Figure 1 shows a vertical cross-section of the device; Figs. 2, 3 and 4 modifications of the means for adjusting the stroke of the'piston for discharging the iiuid.

Similar numerals of reference indicate similar parts throughout the drawings. Referring to the Adrawings, a reservoir. 1 ofany suitablestructure is preferably provided with a hand/le 32 and bail 31, so that it may be portable. A stationary handle 19 suitably attached to the reservoir obviously serves to enable the operator to tilt or invert `mounted on the to said barrel having 1n 'communication wit and an outlet ordischar e pipe 5 which 60 carries any form of disc arge nozzle 4..

it a suction pipey 23,

Said suction pipe 23 is provided with a suction valve which may be located at any Vconvenient place in said pipe, but preferably at its lower extremity. Said suction valve consists of a valve 25, a casing 24 .attached to the pipe 23 and in which is provided the seat for valve 25. A guide 26, preferably provided in the suctionpipe 23, ycarries the stem of the valve 25, and a spring 27 tends 7b to hold said valve on its said seat. Within the discharge pipe 5 or nozzle 4 is located a discharge valve 29 having its stem preferably guided by a shoulder on the interior of the inclosing-case and having a seat 39 and a 75 suitable spring 30 which tends to hold said valve on said seat.

' Operative within the barrel 2 is a piston consisting of guides 8 and 36, packing 6 and 7 to insure tightness in both directions, and 80 packing followers 9 and 10, said guides 36 be- 4 ing held a suitable ldistance from the piston proper by distance piece 11, all said parts being held together by bolt 13, the bolt being securely screwed into guide 36 and into lug 85 12. A spring 28 of suitable strength is preferably provided within the barrel 2 which acts between the piston head and the end of the barrel and tends always-to maintain the piston in the position shown in Fig. l, with the guide 36 abutting against barrel head 3, or it restores the piston to this position in the barrel after the same has .been displaced as hereinafter described. Pivoted to lug 12 by a pivot 16 is a connecting link v14, the other end 95 of said link being provided with threads -or lotherwise adjustably attached to link 15 atV one end'thereof. The other end of said link l5 is pivotally attached by pivot 17 to a movable or. supplementary handle 18, said handle beinlgl pivotally attached by pivot 21 to support 20provided on stationary handle reservoir for filling the same.

' 19. A suitable means 22 is provided in the',

It is evident that by the pressure of the hand on movable -or supplementary handle 18 said handle 4can be forced into the dotted position shown in Fig. 1.- This movementA of the handle is transmitted to the piston through the connecting

links

14 and 15 and the various pivots, and the piston thereby caused to move in barrel or cylinder 2. against .the pressure of spring 28.- Li'quid having been put into the reservoir through inlet 22, and the pumpcavities being full of liquid, the movement of the piston augmente the pressure in said cavities and more securely holds suction valve 25 `on its seat and simulta- .neously raises discharge valve 29 in its seat against the pressure of spring 30, lpermitting escape of -the I fluid fromA the nozzle. As soon as the pistonv has reached the end of its discharge stroke, the augmented pressure in the pump cavities is released and discharge valve 29 is seated by spring 30 cutting ofl' all further discharge of uid by gravity. When manual pressure is removed, spring 28 forces the piston back tothe position shown in Fig. 1, and the vacuum created in the pump cavities by the return of the piston to its normal position, causes'suction valve 25 to raise on its seat against the force of spring 27 and permits the inlet of fluid from the reservoir to 'fiill the said cavities.

It is further evident that the abutment of movable handle 18 against stationary handle 3,19, limits the stroke of the piston in the disi' so 'charge of fluid from the cavities, and that the abutment. of guide 36 against head 3 of the cylinder 2 limits the stroke of the piston in the intake of fluid. The length of connecting

links

14 and 15 between pivots 16 and 17, therefore, determines the length of stroke of the piston, and by adjustment of the stroke the quantity of fiuid discharged from the pump cavities upon each discharge stroke becomes fixed. It is evident that if it is desired to change the quantitiy of fluid to be. delivered from the device,.-it is only necessary to remove either pivot 1 6 or pivot 1 7 and vary the effective length of the connecting rod by screwing or unscrewing one link in the other.

Link 14 may be marked in graduations indi? eating the quantity of fluid which will be def livered when the links are adjusted'l at any one of such graduations. A

It is obvious that the apparatus may be tilted to any angle Without the escape of any iiuid through the nozzle by gravity unless the piston'is forced against the ressure of the spring 28, since discharge va ve 29 tends to always cut off all exit of fluid until it is lifted .from its seat by the excess pressure due to the motion of the piston.

If it is desired to use the device for the discharge of a liquid fertilizer or disinfectant or for other similar uses,'it is only necessary to attach to the nozzle 4 any suitable spraying devtiice' for distributing the 'liquidwhere desire It is'essential in cans of this type to prevent vthe vexposure ofthe contents to air.

This is particularly true of oil since the latter oxidizes when so exposed. For this reason' it is desirable to place the discharge valve as near the outer end of the discharge cavity as possible, so that when this valve isclosed no oil will remain in the discharge cavity beyond `the valve to become oxidized by exposure to 'the air. .I show this preferable situation of the discharge valve in thedrawings.

Another means for adjusting the length of stroke of the piston and thereby predeterinining the quantity of fluid to be delivered is shown in Fig. 2 in Which the rod 38 pivotally connecting lug '12 with movable handle 18 is in ade in one piece, instead of in two links as in Fig. 1, and a stop 37 is inserted through a suitable opening in-head 3 of the cylinder and -made adjustable therein so as to limit the length 'of strokeof the piston in the suction or intake direction to any desiredextent to determine the quantity of fluid to be delivered.

Another means for adjusting the length of stroke ofthe piston is shown in Fig. 3, in which I place theadjustable stop -37 in the movable handle 1-8 instead of in the cylinder head 3 as in Fig. 2. In this case the stop,

j when it abuts handle 19, limits the length of' the discharge stroke of the piston, as is the eiiect of the

adjustable links

14 and 15 in Fig. '1, and consequently by adjustment dctermines the quantity of liquid which shall he discharged. A j

Another modification of the means for adjusting` the length of strokeof the piston is shown in Fig. 4, in which I provide an adjustable connecting device, 40, joining the piston proper and the'guide 36, consisting of a bolt 40 suitably attached to the piston proper and threadedinto and through guide 36, and provided withalsuitable stop 41 to prevent longitudinal motion of the piston proper on the bolt and also with nut 42 with which to adjust the relative position of the piston proper and the guide 36 as desired.

Lug 12 may be attached to guide 36 orlto bolt 40 in any suitable manner. Connecting rod 38 is similar to that shown in Fig. 2. A

stop 43 fixed in the cylinder 2, or Which may .normal position, thereby assistin` inthe rapid handling of the contentsY ofie reservoir byrelieving the operator of the necesmanner that convenience of use may require.

I do not wish to be confined to the precise construction and arrangement of parts as herein shown since these maybe varied Without departing'from the principles of my invention.
