Application led October 29, 1915. Serial No. 58,686.`

To all wiz-0m it may concern:

Be it known that I, Dononr. L. KITTRELL, a citizen of the United States, residing at Nashville. in the county-of -Davidson and State of Tennessee, have 'invented new and useful Improvements in Check-Controlled Apparatus, of which the following is a specification.

This invention relates to improvements in check controlled apparatus and has particular application to apparatus for controlling `the operation of pumps for vending gasolene, although I wish it'to be understood that my invention, in its useful application, may be used in connection with apparatus other than pumps.

In carrying out the present invention, it is my purpose to provide check controlled apparatus which will be found especially useful in controlling pumps for dispensing gasolene and whereby the pump may be operated to deliver the gasoleneonly after a coin of the proper denomination has been -inserted in the apparatus and whereby a predetermined quantity only of the gaso-A lene will be delivered to thepurchaser.

It is also my purpose to provide apparatus of the class described which will operate eciently and effectively under all conditions to control the operation of the pump or other apparatus, which will be capable of a variety of uses and wherein the component parts will be so arranged and correlated as to reduce the possibility of derangement to a minimum.

With the above and other objects in view, the invention consists in the construction,

combination and arrangement of parts here-- inafter set forth in and falling within the scope of the claims.

In thel accompanying drawings; Figure 1 Vis a view in side elevation of check controlled apparatus constructed in accordance with the present invention, the same beingt the parts in the positions they occupy when a coin is inserted in the casing. Fig. 4 is a cross sectional view on the line 4 4 of Fig. 2. Fig. 5 is a similar view on the line 5 5 of Fig. 2. Fig. 6 is an enlarged fragmentary vertical sectional view through the apparatus.

Referring now to the drawings indetail, 1 designates a base constructed of any suitable material, while 2 indicates a supporting frame arranged at one end of the base 1 and upstanding therefrom and in the form of aninverted U. Arranged across the face of the inverted U-shaped frame and suitably fastened tothe legs thereof adjacent to the upper end of the frame is a cross bar 3. Slidably mounted within vertically alining bearings carriedby the upper end of the frame 2 and the cross bar 3 respectively is a vertical rod 4 capable of vertical sliding movement and having the lowerend thereof connected with the upper extremity of the piston rod 5 of the pump 6, the piston rod working within an opening formed in the base 1. -Formed on one edge of the rod 4 are teeth 7, While ivoted upon the cross bar 3 is a lever 8 having the lower end formed with'a dog 9 and thev upper end weighted as at 10 and acting to hold thedog end of the lever normally in engagement with the teeth 7. Formed upon the opposite edge of the bar 4 are teeth 11 and pivoted upon the cross bar 3 adjacent to the teeth 1l isadog 12 normally held out of engagement with l the adjacent ratchet .teeth 11. 'Ihe teeth. 11 are arranged reversely to the teeth 7. Also formed on one edge of the rod 4 is a series of gear teeth 13 and meshing with the teeth 13 is a pinion 14 mounted upon a shaft j ournaled in the upper end of the frame 2 and connected to one end of this shaft is a crank handle 15 whereby the pinion may be rotated to slide the rod. Secured to the base 1 and projecting upwardly therefrom is a vertical standard disposed adjacent to one edge of the frame 2 and pivoted upon the upper end of the standard 1G is a horizontal beam 17. Secured to one end of the beam 17 is a yoke 18 and pivoted between the limbs of the yoke 18 is a coin receptacle 19 provided with a downwardly projecting curved wing 20. rll`he opposite end of the beam 17 is offset downwardly as at 21 and slidably mounted upon the offset portion of the beam is a weight 22 and balancing the coin receptacle 19.

23 designates a vertical` rod having the lower end thereof slidably mounted within an opening in the base and the upper end slidably mounted in an opening in the upper extremity of the frame 2. djustably mounted upon the rod 23 is a pin 24 disposed adjacent to the end of the odset portion 21 of the beam 19 and normally holding such end of the beam against downward movement underthe action of the counterweight 22. Also upsta'nding from the base 1 adjacent to the A-yoke end of the beam and below such end is a short standard 25 and pivoted upon the upper end of the'standard 25 is a trip 26 connected by means of a wire 27 with one leg of a bell crank lever 28 pivoted upon the leg of the frame 2 adjacent to the opposite end portion of the beam. Pivoted'to the remaining leg' of the bell crank lever and projecting upwardly therefrom is alink 29 having the upper end thereof connected with ana-rm' 29 secured to the rod 23. 4Secured to the lower end of the rod 4 and projecting outwardly therefrom and loosely surrounding the rod 23 is a lug 32. 36-d`esignates an arm secured to the beam 17 at the fulcrum point of suchbeam and projecting upwardly therefrom, while 37 indicates a wire-connecting the upper end of the arm 36 with one endof a link 37. The other end ofthe link 37, is connected through a -pin and slot connection '30 with the-dog end of the lever 8, and by a wire 31 with the dog 12.

33' designates a casing inclosing the mechanism just described and formed' with a coin slot 34 yfrom which extends a coin chute 35 leading to the receptacle 19.

ln practice, the receptacle 19 is' normally disposed contiguous to the lower end of the chute 35, while the dog end of the lever 8 holds the rod 4 normally at its limit of downward movement and prevents movementof the rod under lthe action ofthe handle. W'hen it is desired to actuate the rod 4 a coin of the proper denomination is deposited in the slot 34' and falls down the chute 35 into the rceptacle 19 and when the coin enters the receptacle the counterweight 22 is overbalanced and the beam 17 swung about its pivotal Vconnection with the standard 16 and in this movement ofthe beam 17 the arm 36 pulls upon the wire 37 and so actuates the link 37 with the e'ect to move the dog end of the lever 8 out of engagement with the teeth? and the pawl 12 into engagement with 4the teeth 11. The crank handle 15 may now be rotated and in the rotation of thev crank handle the rod 4 will be moved in one direction to move the pump piston from one end of the cylinder to the other. As the rod 4 moves upwardly the lug 32 slides upwardly along the rod 23 and engages the pin 24 with the effect to elevate such rod 23 and in the continued upward movement of the rod, the pin 24 is carried into engagement with the adjacent end of the beam 17 and swings the yoke end of the beam downwardly. Simultaneously with vthe downward movement of the yoke end of the beam 17, the trip 26 is swung upwardly through the medium of the arm 29', link 29, bell crank lever 28, and the wire 27, incident to the upward movement of the rod 23 to which the arm 29 is connected, and in the downward movement of the yoke end of the beam 17, and the upward movement of the trip26, the wing 20 is struck-by the trip vwith the effect to tilt the coin receptacle to discharge the" coin therefrom.

Upon the discharge of the coin from the receptacle 19 the counterweight22 swings the beam 17 in the reverse direction and the arm 36 and wire 37 restore the dogs to normal positions, thereby permitting the rod l to be moved in the opposite direction under the action of the crank handle to move the piston toward the opposite end of the cylinder. Upon the movement of the pawls to normal positions the bell crank lever and trip 26 are likewise restored to their original positions so that the above cycle of operations may be repeated when another coin is deposited in the slot.

lVhile I have herein shown and described one preferred form of my invention by way.

of illustration, l wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.
