LIQUID MEASURE AND REGISTER.

Specification of Letters Patent.

Patented Oct. 2'7. 1914:.

Application filed September 24., 1910. Serial No. 583,640.

To all whom it may concern:

Be it known that I, WILLIAM J. HUGHES, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improve- .ments in Liquid Measures and Registers, of

which the following is a specification.

This invention relates to improvements in oil wagons, and has particular reference to attachments therefor to measure and register the fluid drawn therefrom.

One object of the invention is to provide a measuring receptacle into which the fluid contained in the tank on the wagon is drawn, and the number of times the said receptacle is filled, is checked by a suitable registering mechanism.

Another object is the provision of an inlet and outlet valve, operable by a lever mechanism so that when one valve is opened the other is closed, in order to permit the measuring receptacle to fill and empty acording to the movement of the lever.

A further object is to provide means in connection with the inlet valve to permit the entrance of air to'the receptacle, to assist in the outwardfiow of the fluid therein drawn, and when the outlet valve is open.

A still further object is to so construct the registering mechanism that when the limit of its register has been reached, any further attempt at the device, to draw more fluid, would result in the destruction of one of the counter wheels, thus indicating that an at tempt had been made to defraud the employer.

Other objects Qind advantages will appear asthe description proceeds.

In the accompanying drawing, in-whioh is shown a device of the character described,

made in accordance with my invention, Figure 1 is a side elevation of a tank wagon, showing my invention applied thereto, Fig. 2 is an end view of the same, Fig. 3 is a vertical longitudinal sectional view through the measuring receptaclefthe valves being in position to permit the filling of' the receptacle, Fig. 4is similar sectional view showing the I valves in position to empty the receptacle,

Fig. 5 is afront elevation of the measuring receptacle, the cover of the counter or registering mechanism being removed, Fig. 6 is a rear elevation of the same, showing the position of the locking pawl for the hundredths wheel, Fig. 7 is a vertical section on the line 7-7 of Fig. 5, Fig. 8 is a section on the line 88, of Fig. 5. Fig. 9 is a section on the line 9-9 of Fig. 5, looking in the di rection of the arrows, tive'view of the inlet valve, removed from its seat.

Referrln now to the accompanying drawings, represents a wagon having suitably mounted thereon a tank B, both of which are of the common type used in the oil trade, for dispensing oil, the latter of which is provided with a threaded nipple 1, by

means of which my invention is readily applied to the tank.

A receptacle 3, having the vertical parallel side walls 4, and the front and rear parallel walls 5 and 6, is provided in the said rear wall 6 with an interiorly threaded nipple 2, adapted for attachment to the nipple 1 of the tank B. The said nipple 2 projects rearwardly from the upper portion of the rear wall 6 of the receptacle, and in said nipple adjacent the receptacle is formed the valve seat 8, extending transversely of the receptacle, and in which is seated the plug valve 9. This valve is a straight way valve having the transverse passage 10 there through, and the smaller passage 11 passing through one of the side walls of the passage 10. and letting into the receptacle. when the valve is in the position of Fig. 4. In the top of the casing of the receptacle 3, and letting into the valve seat 8, is an air inlet 12, which, when the valve 9 is in the position shown in Fig. 4, will permit air to pass through the Fig. 10 is a perspec- 4 passages 10 and 11, and into the receptacle. I

This provides for the admission of air to assist the fluid in the receptacle to pass out through the spout 13, located at the forward end of the receptacle.

The receptacle 3 has its upper and lower walls 14 and 15 inclined downwardly toward the front wall 5, 'so that the liquid within the receptacle would more readily flow toward the front Wall and through the spout 13. In the lower forward portion of the receptacle, and communicating with the spout 13, is a valve seat 16 for the reception of the oscillatory valie 17 similar to the valve 9, this valve having a passage 17', which will he more fully referred to hereinafter. The stem of the valve 9 has an arm 19 secured theretopwhile the stem of the valve 17 has an arm 18 secured thereto, these arms being pivotally connected together by means of the link 20, to provide for their simultaneous movement by a single movement of the arm 18. Thearm 18 extends vertically above the pivotal point of the link 20, to provide a handle by means of which the valves are oscillated. When the lever 18 is drawn forwardly, the valves 9 and 17 will be turned into the positions shown in Fig. 4, the valve 9 being closed to cut ofi communication from the tank B and the valve 17 open to permit the liquid in the receptacle 3 to pass through the spout 13. The n'ormal positions of the valves and levers are shown in Figs. 1 and 3, where the valve 9 is open to permit fluid from the tank B to pass into the receptacle 3. Mounted in the front wall of the receptacle 3, above the spout 13 is a pop valve 21'to which is connected a curved pipe 21 extending into the receptacle 3 and terminating at a point adjacent the valve 9. In the forward wall 5 and establishing communication between the pop valve and the valve seat 16 is a short diagonal passage 5'. 'hen the receptacle 3 is full. the air in the upper portion of the receptacle will pass out through the pipe 21 and through the pop valve 21. The air will issue with a slight hiss so that the fact that the receptacle is full will be clearly indicated. hen the handle 18 is thrown to close the valve 9 and open the valve 17. the passage 17 in the valve 17 registers with the passage 5 so that the oil in the pipe 21 which splashes thereinto during the filling of the receptacle 3 will flow through the passage 5. passage 17. and be drawn out by the oil issuing from the receptacle through the spout 13, The opening 11 in the valve 9, and the opening 17 in the valve 17 are so positioned with respect to each other that when the transverse passage in the valve 17 is in registry with the passage 5 the opening 11 will be in communication with the interior of the receptacle. and at the same time the passage 10 will be in communication with the opening 12. This permits air from without the receptacle to enter the receptacle during the emptying of the receptacle.

The receptacle illustrated in the accompanying drawings is intended to contain five (5) gallons, but receptacles containing more or less may be used as conditions require.

On the end of the valve 17 opposite to that which carries the lever 18, and exteriorly of the receptacle 3 is mounted a registering mechanism. valve has formed integral therewith a reduced cylindrical extension 22, and secured This end of the thereon is a. disk 23. Pivotally carried on this disk is a pawl 24; which engages with a ratchet wheel 25 formed integrally with a combination units-and-tens counterwheel 26 loosely mounted on the extension On the outer side of the counterwheel 26, and formed integrally therewith is a disk 27 carrying a single radial tooth 28 which is arranged for engagement with a pinion 29 mounted on a shaft above and parallel with the extension 22. Beyond the disk 27, and loosely mounted on the extension or shaft 22 is a hundreds counter-wheel 31, this wheel carrying an integral gear 32 which constantly meshes with the pinion 29. It will thus be seen that when the valve 17 is rotated, the disk 23 will move the pawl into engagement with the ratchet wheel 25 and cause a partial rotation thereof together with the counterwheel 26. The counterwheel 26 is provided with numbers on its peripheral face in multiples of five up to ninety-five while the counterwheel 31 has the numbers in multiples of one (1) up to nineteen (19), thus making the full capacity of the register 1995, but this may be varied according to conditions as required.

Secured to the side. of the receptacle 3 and embracing the countermechanism is a support which includes the upper and lower outwardly extending parallel portions 34 and 34: which are connected by a vertical portion 33. The outer end'of the extension or shaft 22 is journaled in this vertical portion 33. This support is secured by means of the bolts 35. The registering mechanism is suitably housed. and this housing is provided with a hinged cover 42 in which is formed a sight opening (not shown). In the lower portion 34 is formed a slot 36, and depending in this slot is the weighted enlargement 2% of the pawl 24. This weight is adapted to engage the end wall of the slot when the disk 23 is rotated by the valve 17, and lifts the weighted end of the pawl so as to release the nose thereof from engagement with the ratchet wheel The nose of the pawl 2i is in-engagement with the tooth of the ratchet wheel 25 when the weighted cnd 2i depends through the slot. and when the disk 23 is given a partial rotation. the pawl will move the ratchet wheel the distance of one notch and then he rocked away from the ratchet wheel when the v. eight 2% engages the end wall of the slot 36. By this arrangement the counter-wheel is turned one notch at the same instant that the valve 9 begins to close and the valve 17 to open. thus preventing the drav-sing of the contents of the receptacle :3 without first registering the amount contained therein.

With the device as thus far described, it would be possible for the salesman to work the lever 18 back and forth, and draw out an amount of fluid, say about two gallons, after he had completed his days sales, and pocket the receipts of the two (2) gallons. Suppose the amount of the days sales to be be five hundred (500) gallons. The register would indicate that five hundred (500) gallons had been sold, and by working the lever 18 back and forth, oil or other fluid could be drawn from the receptacle 3 while at the same time the register would be turned to the limit of the register, and back to the five hundred (500) mark again. Thus five hundred and two (502) gallons would be drawn; and the amount drawn which exceeded the live hundred gallons, would be lost to the employer, and evidence of the loss be lacking unlesss the tank B were emptied and its contents measured. To obviate this fraudulent process, 1 provide the hundreds wheel with an annular groove 37 in one of its side faces, in which is adapted to ride the nose 40 of a spring pressed pawl 39. At a point 38 ,-in the annular groove is formed a stop notch, into which the nose of the pawl is adapted to drop, to prevent the further movement of the register. This pawl is pivot-all mounted on a support ll, on the bottom we 1 3d of the support for the registering mechanism, and has its lower end projecting at right angles to the body of the pawl and in a plane parall l with its pivot, said projecting end forming a finger piece l0, by means of which the pawl is released from the notch 38, when the register is to be reset. This notch is so placed with relation to the number on the disk 31 corresponding to the capacit of the tank B, that any attempt to manipunte the counter would le frustrated. by the fact that the pawl locks said disk from any further rotation, without injury (/0 the counterwheel 31. Thus when the arm 18 is manipulated for the last time, to draw the last five gallons from the tank B, the pawl 40 will enter the notch 38, at the same time that the highest number of the register appeared through the sight opening. Were the counter-wheels made of metal, it would be possible, by usin force, to bend the pawl out of the way, an( permit the wheels to rotate beyond the limit of register, and farther to the number desired to be shown through the sight opening in the cover 42, to indicate the total of gallons sold, and for which returns were to be made-to the employer. At the same time fluid could be drawn from the tank, and not be detected. To avoid this I make the counter-wheel 31 of hard rubber, or other suitable frangible substance, and very thin,

is desired to set back the so that it will break when the nose of the pawl 35) enters the notch 38, and an attem t is made to actuate the register beyond t e limit of registration thereof. Thus the sin ployer would know b the broken Wheel when he had opened t e cover of the register, that an attempt had been made to defraud him. The finger piece of the pawl is lccated within convenient reach when it register. The cover of the registering mechanism is provided with a suitable lock 43, to prevent access to the mechanism, exceptby authorized parties.

The valves, the lever mechanism, and the counter or register are so correlated that the number of gallons are registered the instant the valves begin to change their positions, or to be more accurate, the reg ister operates slightly prior to the opening of the inlet valve, so that the amount to be drawn is registered and of necessity has to be drawn.

From the foregoing, it will readily be seen that I have provided a simple and etlicient device of this character, which will put a check on the sales made by the employees, and positively indicate when any fraudulent act has been tried on the device, thus revealing any dishonesty on the the part of the employees. The fact that inlet valve is so timed with relation the register makes it impossible for t J honest salesman to draw less than the pacity or the receptacle 3, without regi ing the full capacity of said recept Should the salesman desire to sell an am of oil less than five (5) gallons so tha could pocket the money, he would h register five (5) gallons in less than that amount.

What is claimed is: 1. A pawl and ratchet device in .1 istering mechanism including a suppo frame, a rock shaft mounted in the a disk fixed on the shaft, a ratchet wheel loosely mounted on the shaft adjacent the disk, a spring pressed pawl pivotally carried by the disk and engaging the ratchet wheel, said pawl having a weighted end, and means on the frame for engagement by the.said weighted end to rock the pawl out of engagelnent with the ratchet wheel after the pawl has moved the ratchet wheel re quired distance.

2. A registering mechanism includin support, a shaft, a disk fixed on t s a spring pressed pawl pivotally carried on the disk, said pawl having a depending weighted enlargement, the lower portion of the support being slotted to receive de pending weighted portion, said depending engage the end portion being adapted to AIL In testimony whereof I afiix my signature,

in the presence of two witnesses.
