ALFRED PETTERSON HALD, OF MINNEAPOLIS, MINNESOTA.

GREASE-SCALE.

Application filed May 14, 1915.

l '0 all whom it may concern:

Be it known that I, ALFRED PETTERSON HALD, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and Improved Grease-Scale, of which the following is a full, clear, and exact description.

My invention relates to mechanism for holding and distributing grease and oils of various kinds, my more particular purpose being to provide a container for holding the grease or oil and for determining exactly the amount of said grease or oil as removed from time to time.

Stated more in detail, my invention comprehends one or more tanks and a frame for supporting and handling the same, together with a scale carried by the frame for weighing the tank or tanks from time to time in order to determinethe amounts of oil or grease removed therefrom.

My invention further comprehends means for shifting the weight of the tank or tanks from the scale to a supporting device located below the scale and carried by the framework.

My invention also comprehends means for steadying the tank or tanks in order to facilitate the removal of the frame and various parts carried thereby.

My invention contemplates other improvements upon mechanism of this general character.

Reference is made to the accompanying drawings forming a part of this specification and in which like letters indicate like parts.

Figure 1 is a side elevation of a device embodying my invention and shown as partly broken away and using in this instance only a single tank. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a fragmentary elevation showing the lower part of the frame and parts carried thereby. Fig. 4 is a horizontal section showing my device as used with a plurality of tanks forming ia cluster.

A U' frame 5 is mounted upon caster wheels 6, 7 and provided with bearings 5 in which are journaled crank bars 8, 9, the latter being provided with horizontally disposed portions 10 which are straight and flat, and adapted to form a supporting surface. The crank bars 8, 8 are further provided with jaws 11 of arcuate form so ar- Specification of Letters Patent.

ranged as to move toward each other and from each other as the crank bars 8, 9 are rocked.

Mounted rigidly upon the crank bar 8 is a hand lever 12 and pivotally connected with this lever is a pitman 13. This pitman is pi votally connected to an arm 14, the latter being mounted rigidly upon the crank bar 9. The operator by grasping the hand lever 12 can move it into different positions, as indicated by full and dotted lines in Fig. 3. \Vhen the hand lever 12 is in its extreme position to the left, as indicated in Fig. 3, the crank bars 8, are slightly off center; that is, the supporting portions 10 are slightly nearer together than are the axial centers upon which the crank bars are adapted to rock.

Mounted upon the U-frame is a T 15 and extending upwardly from this T is a standard 16, the upper portion of which is bent substantially into horizontal position as may be understood from Fig. 1. Secured to the standard 16 and extending downwardly therefrom to the frame 5 are two braces 17, which are curved as indicated in Fig. 2. A tank is shown at 18 and carries a quantity of liquid grease 18. Connected with the bottom of the tank is a discharge pipe 19 which is provided with a screen 20, as indicated in Fig. 1. The purpose of the screen is to facilitate the retention and subsequent removal of the impurities including particles of iron or grit.- The tank 18 is provided at its top with an air-tight filler cap 18. A hose 21 is con nected with the discharge pipe 19 and carries a discharge nozzle 22 and a hand valve 23. The purpose of the hose, the discharge nozzle and the hand valve is to enable the operator to discharge grease from the tank 18 directly into any part of an automobile or the like as may be desired.

Mounted upon the upper end of the tank 18 is a support 24 having a horn-like form, and upon this support the hose 21, when not in active use, may be rested or coiled. The support 24: is provided with an eye 25 and a hook 26 is adapted to extend through this eye. A scale 27, having in this instance the general form of a steelyard is provided with a bearing 28 upon which it is mounted, this bearing having an upwardly extending bolt 29 which projects through the upper portion of the standard 16. A wing nut 30 engages the bolt 29 and rests upon the adjacent portion of the standard 16. The scale 27 is provided with appropriate weights 3], 32, and

is otherwise adapted for the purpose of weighing. A pressure gage 33 is mounted upon the tank 18 and serves to indicate the degree of air pressure therein.

Mounted upon the upper end of the tank 18 is a head 3i, provided with a valve 3?) and with a nipple 36. The head is further provided with another nipple 36 and by the aid of these nipples is used for admitting 'air under pressure into the tank 18, and for releasing said air therefrom as desired. The nipple 36 is an air inlet and is provided with a check valve 36".

The filler cap 18 is used for admitting grease or oil into the tank.

The mechanism shown in Figs. 1, 2 and 3 is used as follows: The tank 18 being filled or partially filled with liquid grease, is lifted up and rested upon the portions 10, 10 of the crank bars 8, 9, the hook 26 being extended through the eye 25. The hose and various other parts being now in position, the operator by moving the handle lever 12 to the right according to Fig. 3 dislodges the supporting portions 10 of the crank bars from their engagement with the bottom of the tank. The tank is thus left suspended, and the scale 27 can now be used for determining and indir eating the weight of the grease total within the tank. This being done, suppose next that the operator wishes to use a portion of the grease for filling some receptacle of an automobile or for greasing some part of the mechanism thereof by the aid of the hose 21, nozzle 22 and hand valve 23, the operator draws off from the tank 18 an amount of grease suflicient to accomplish the purpose desired. By aid of the scale 2-7 he now determines the total weight of the tank 18 and its contents, and this total weight being subtracted from the total weight first found, gives the exact amount of grease which has been removed from the tank. After each weighing by aid of the scale 27 it may be desirable that the tank lS shall no longer hang from the scale, but shall be supported from below. This object is easily accomplished by simply shifting the hand lever 12, as above described.

The U-form 5 and caster wheels 6, 7, together with the parts carried thereby, constitute practically a truck from which the tank -18 can be readily wheeled from one place to another. As a general rule when this is being done, it is desirable that the tank shall rest upon the supporting portions 10 of the crank bars as above explained.

In Figi 4, I show a slightly different form of my device. A frame 37 is mounted upon caster wheels 88, 39 and extending upwardly from the frame 37 is a standard 40 corresponding to the standard 16 above described. A board 41 supports a number of tanks 42, 43, 441, in this instance three in number, arranged as a cluster. By aid of nipples 45, 47,

and a valve 416 air can be introduced under pressure into the tanks. A Y-tube 1-8 communicates directly with the tank -12, and by aid of pipes 49, 50 also communicates with the tanks 43, 11 in such manner that the air pressure is always alike for all three of the tanks.

Connected with the several tanks 1-2, 1-3, ll. are hoses 51, 53 for discharging grease therefrom. Mounted rigidly upon the board ll and extending up\ ardly from the same is a suspension rod 5% which at its upper end carries an eye This eye corresponds to the eye 25 shown in Fig. 1, and isadapted to engage the hook 26 carried by the scale.

In using the form of my device indicated in Fig. 4, the cluster of tanks 12, 43, 4 1 is treated as a unit for purposes of weighing and for purposes of establishing and maintaining the air pressure common to the three tanks. Different kinds of greases or oils, however, are placed within the three tanks and are discharged independently through the different hoses 51, 52, The cluster of tanks as a unit is weighed before and after each discharge of grease from any one of the tanks. In this manner the same scale is used to indicate different amounts of grease removed from time to time from the different tanks. It may be remarked in this relation that the removal of grease from a tank to an automobile is ordinarily a more difficult and unsatisfactory undertaking than is generally realized. If a grease gun be employed there is the attendant disadvantage that particles of grit and even small metallic objects such as bicycle balls are carried in with the grease and liable to do damage. Again, a grease gun has to be carried by hand and must either be very large and heavy, or else must be frequently replenished. All of these attendant disadvantages are done away with by the use of my improved device. Moreover, by aid of the invention the operator can determine exactly the amount of grease for which he should charge the automobile operator, and the device saves considerable time in figuring or estimating the grease thus used.

I do not limit myself to the precise con- 5 struction shown as variations may be made therefrom without departing from the spirit of my invention.
