Application August 10,

4 Claims.

'Ihis invention relates to improvements in signal devices and pertains particularly to a signal device designed for -use in association with a dispensing apparatus.

The primary object -of the present invention is to provide a device designed for application to a dispensing faucet, upon which a receiving receptacle may be suspended and which will indicate by an unmistakable signal when a predetermined quantity vof fluid has passed into the receptacle.

Another object -of the invention is to provide a sig-nal device of the above described character which is of simple design, leasily attached to or detached `from a dispensing faucet, and requiring little attention Ato 'keep in order.

'The invention will 'be ybest lunderstood from a consideration of thefollowing Vdetailed description taken in connection with the accompanying drawing forming part v`of this specification, with the understanding, however, that the invention is not confined to any strict `conformity vwith the showing -of the drawing but may be changed -or modified so longas such-changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:-

Figure 1 is a view -illustrating the application of the device embodying the present invention to a dispensing faucet and showing, in broken lines, a receptacle suspended therefrom;

Figure 2 is a view of the interior of `the device looking at the same from the rear, portions being in section;

Figure 3 is a vertical sectional view taken substantially upon 'the line 3-3 of Figure 2;

Figure 4 is a sectional view taken substantially upon the line 4 4 -of Figure 3.'

Referring now more particularly to the-drawing wherein like numerals of reference indicate lcorresponding parts throughout the several views, the numeral I indicates a faucet of the type commonly employed von tank wagons in which gasoline, oil or Aother liquids are transported. From these vwagons fthe liquid is drawn off through the faucet into Areceptacles of diiferent capacities, for sale.

The device'embodying the present invention is designed to be attached tothe pipe 2 with which the faucet r`I is connected and is indicated as a whole by the numeral 3.

The device 3 comprises a casing III having a transparent front panel 5 and a removable back Lwallfii. Connected with the casing is aclamp of Bronaugh, Mo.

a suitable character, such for example as the split ring clamp l, the ends of which are drawn together by a connecting bolt 8, by means of which the device is attached to the pipe 2 to be suspended therefrom.

Within the casing Il is mounted, in spaced relation with the transparent rpanel 5, the dial 9, the outer face of which is viewable through the glass panel 5 and bears an annular series of notations which in the present case are illustrated as run- 10 ning by ves from zero to one hundred. These notations in the present instance represent gallons of liquid.

Extending through the radial center of the dial 9 and through the back 6 and passing through 15 the casing 4, is a shaft ID upon the forward end of which is a signal indicator hand II which rotates over the face of the dial behind the glass panel 5.

Upon the opposite side of the casing and the 2o other end of the shaft I 0, isa key I2 by means of which the shaft may be rotated when and as necessary.

Within the casing 4 there is secured the body I3 against the back of the dial S and the shaft 25 I0 passes through the center of this body. Pivota'lly mounted upon the body I3 at the point I4 is a pawl YI5 which is integral with the elongated tail-piece .IG which terminates in an angularly extending arm I l. Upon this arm `I1 is 30 fixed a hammer I8.

Mounted kupon the back of the dial 9 isa bell I9 adjacent which the hammer I8 .is disposed and with which the hammer comes in contact during the operation ofthe device to give the de- 35 sired signals.

A pin 2B mounted upon the back of the dial 10 has secured thereto one end of a flat spring 2I which intermediate its ends extends across and is in contact witha stop pin 22. Connected 40 vwith the free end of the spring 2| is a link '23 through which the tail-piece IS of the ,pawl passes.

Mounted upon the shaft l0 for free rotation therewith, is a drum 24 having a flange 25 in 45 which are formed the teeth 2S. Upon the back of the drum 24 is a ratchet 21 with the teeth of which the pawl I5 engages.

The shaft vIS extends through one end of a lever arm 28 and the arm rocks freely on this 50 shaft. This arm 28 passes across the toothed edge 25 of the drum 24 and extends through an aperture 29 in the wall of the casing 4, terminating at its outer end, exteriorly of the casing 4, in the Ahook 3D. 'The loweredge of this ap- .55

, erture 23 limits the downward movement of the arm 2&3 and as the arm is swung down its lower edge, which is in contact with a tooth 25, causes a partial rotation of the drum 2li upon the shaft. The lever arm 2B is of suitable iiexibility to permit it to bend slightly laterally to pass over the teethi in its reverse movement on the shaft. Suitable means is employed for retaining the arm 28 in its proper position on the shaft, such for example, as the collar Si. This retains the inner end of the arm in place.

Extending through a boss 32 upon the outside of the wall of the casing is a threaded stem 33 with which is engaged a nut Sli which rests upon the boss.

provide a hook 35. Surrounding the bifurcated portion of the stem 33 is a coil spring 35, the

lower end of which rests against the hooks 35. The upper end of the spring 35 is connected with a linke? which passes downwardly therethrough and has engagement with the arm 25 as is clearly shown in Figures 2 and 4. By the adjustment of thernut 3ft upon the stem 33 the tension of the spring can be'Y increased or decreased as it will tend to pull the arm upward while its movement is limited by the Yupper edge of the aperture 29. j In the operation ofthe present device after thesame has been attached to a faucet pipe as illustrated in Figure l and the nut 313 adjusted to properly tension the spring 36, when a receptacle, such as is indicated at 38, is suspended from the hook 3i it will be disposed beneath the faucet Vl to receive iiuid therefrom and when the faucet is opened and an amount of iiuid equal to five gallons has flowed into the receptacle, the arm 28 will have been pulled down to the point where, through its contact with one of the teeth 25, the drum 2e will have been rotated sufficiently to cause a tooth of the ratchet 2 to pass the point of the pawl l5. As the tooth of the ratchet 2'! Vis riding under the point of the pawl l5 the tail portion le of the pawl will be swung so as to Vflex the spring 2| and when the pawl snaps off of the tooth the hammer I8 will be caused to vsnap back against the bell, Vthus signalling tothe attendantthat the receptacle 3S contains a predetermined amount of the liquid.

Itis, of course, to be understood that various `adjustments of the tension of the spring 35 must lthe device may be used continuously for the same .iiuid and with the same receptacle to measure off ments may be made to suit the convenience of the Y user and the invention is not to be restricted to the particular form and arrangement illustrated.
