SPECIFICATION forming part of Letters Patent No. 777,923, dated December 20, 1904.

Application filed December '7, 1903. Serial No. 184,067.

T 0 all whom it may concern:

Be it known that 1, AZ SATTERFIELD, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Check-Controlled Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

My improvement relates particularly to check controlled apparatus comprising a crank which is to be actuated for performing the function designed to be performed in exchange for the check which is deposited into the apparatus.

The apparatus is applicable to machines for vending liquids, gases, and other commodities and for controlling musical instruments, &c.

In the accompanying drawings, Figure 1 is a front elevation with a portion of the front wall of the case removed to expose the interior mechanism. Fig. 2 is a vertical transverse section on the line2 2 of Fig. 1. Figs. 3, 4, 5. 6, and 7 are detail views of the check-driving mechanism. Figs. 8, 9, and 10 are details of a portion of the releasing mechanism.

Referring to said drawings, 1 is the front wall of the case which incloses the greater portion of the operating mechanism. 2 2are the side walls of said case. 3 is the top of the case, and 1 is the bottom thereof. These portions of the case may be in any suitable form, and they may be of any suitable material.

Upon the front portion of the top and in the plane of the inner face of the front wall 1 is a metallic upward extension of the case, said extension consisting of a front plate 5 and a rear plate 6. The front face of the rear plate 6 is provided with marginal ribs 7, which bear against the front plate 5 for the forming of a chamber between the plates 5 and 6 to be used for a portion of the check-passage and for containing a portion of the mechanism whereby the crank is releasably controlled.

At the central portion of the case is locatec a horizontal shaft 8 axially perpendicular to the front wall of the case, and 9 is a crank applied to said shaft for imparting rotation or partial rotation to saidshaft. Said shaft is suitably joined to any mechanism which is designed to be operated to deliver any goods or perform any function or service in exchange for one of the particular checks to which the machine is adapted. In the drawings said shaft is shown joined to a measuring-valve B, which receives liquid from a pipe A and discharges said liquid through the pipe C. The handle 10 of said crank extends forward through a slot 12 cut through the front wall 1 concentric with the axis of the shaft 8. The drawings show said slot extending through a quadrant of a circle. Thus the handle of said crank is outside of the case and may be grasped by a person standing in front of said case; but the arm 11 of the crank is within the case and there controlled by mechanism which is inaccessible to a person standing in front of the case. The first member of the mechanism for controlling the crank-arm is a pawl13, located above the upper portion of the slot 12 and hinged flatwise againstthe inner face of the wall 1 by a suitable stud or post 14:, extending rearward from the inner face of said wall through said pawl. Being thus hinged the free end of said pawl may approach and recede from said slot. Said pawl has a depending hook 15 almost directly above the upper end of the slot 12, and the drawings show said pawl also provided with a second hook 16, approximately midway between the two ends of the slot 12. The crank-arm 11 is sufliciently long to cause the path of the outer end of said arm to cross said hooks 15 and 16, to the end that when the crank-arm is in the upright position the hook 15 will stand in front of the upper end of said arm and lock the latter in said position and to the end that if the crank-arm is between said hooks it cannot pass downward beyond the hook 16, because said arm will when it moves downward meet the hook 16 and be arrested thereby. The lower face of each of said hooks is oblique to the path of the end of the crank-arm in order that the pawl may be pressed upward by the free end of the crank-arm when the latter is moved upward. If so desired, the apparatus may be so arranged as that the operation desired by the person depositing the check will be performed by the movement of the crank-handle from the upper portion of the slot 12 to the lower portion, or the apparatus may be so constructed as to require the down ward movement of the crank and also the reverse movement of the crank to complete the operation desired by the person depositing the check. If the operation is performed by only the direct movement of the crank, a contracting-spring 17 may be applied by one end to said crank and by the other end to some relatively stationary part of the apparatus for effecting the reverse movement of the crank when the latter has been released by the operator. My apparatus embodies mechanism combined with said pawl and extending into such relation with the check-passage as to be operated by a check going through said passage in such manner as to raise said pawl sufficiently to bring the hooks and 16 out of the path-of the upper end of the crank-arm. Said mechanism will be next described.

At a distance below the upper rib 7 equal to the diameter of the check to be used the rear plate 6 has a similar rib 18 extending from one end of the plate 6 beyond the middle of the latter. A section equal in length to the diameter of the check to be used is cut out of the upper portion of the rib 7, and from each side of the opening thus made a rib 19 extends upward to the upper edge of the plate 6. Said ribs are preferably inclined, so as to form an indirect check-chute leading into the horizontal passage between the ribs 7 and 18.

A lever 20 is located beneath said passage and pivoted upon a stud 21, projecting horizontally from the front face of the plate 6. The upper end of said lever is expanded in the plane of the check-passage and rises a short distance above the lower portion of said passage, so that the space between said end and the upper wall of said passage (the rib 7) is less than the diameter of the checks, whereby the passage of a check beyond the open end of the check-passage can be effected only by forcing said end of said lever downward. The lower or opposite end of said lever is formed with a notch 22, in which rests the hook 23 of the link 24:. The lower end of said link is suitably hinged to the pawl 13, as by a short arm 25, extending laterally into a lug 26 on the pawl 13. It will be readily understood that the passage of a check through the open end of the check-passage over the upper end of said lever 20 will tilt the latter and lift said link 24, and thereby cause the latter to lift said pawl, and that if the dimensions of the several parts are properly proportioned the hooks 15 and 16 will rise above the path of the free end of the crank-arm, so that the crank is free to be turned downward, and, as already described, the lower faces of the hooks 15 and 16 are oblique, so that said hooks are adapted to be at any time pressed upward by the reverse movement of the crank; but the pawl 13 cannot descend so long as the check is held between the upper end of the lever 20 'and the adjacent portion of the rib 7, and it is necessary to permit the pawl to descend as soon as the free end of the crankis passed downward beyond said pawl. For this purpose I employ mechanism for tilting the lever 20 away from the check and holding it so until the crank-arm has passed downward beyond both hooks of the pawl 13, said mechanism for effecting such tilting being actuated by said crank or some part connected with said crank. For this purpose I use a reciprocatory bar 27, supported on the inner face of the wall 1 and between the plates 5 and 6 by a stationary horizontal stud 28, extending from the rear plate 6 through a longitudinal slot 29 in the upper portion of said bar, and a stud 30, extending from the wall 1 through another longitudinal slot 29 in the lower portion of said bar. The upper end of said bar is held against forward and backward movement by means of the plates 5 and 6, and the lower end of said 'bar is held in position on the stud 30 by means of a head on said stud. The upper end of said bar 27 extends against or nearly against the lower edge of the lever 20 at the side of the pivot of the latter at which the notch 22 is located when said lever is in its normal position in order that the lifting of said bar may tilt said lever, so as to lower the end of the latter which extends into the checkpassage. Since the bar 27 and the lever 20 merely abut against each other, but are not joined, the lever 20 may be tilted by the forward movement of the check without lifting said bar, and since the book 23 of the link 24: rests loosely in the notch 22 said link and the pawl 13 may move upward independently of the lever 20 and the bar 27. Such movement takes place during the reverse movement of the crank, the upper end of the crank-arm pressing against the oblique faces of the hooks 15 and 16 and raising said pawl and said link. At its lower end said bar has a rearward-directed spur 32, having a lower horizontal face and an upper oblique face. Said spur rests in a slot 33, and a pin 34 extends through said bar and the upper end of said spur, whereby said spur is hinged to permit forward movement of the lower portion of said spur until the oblique face of said spur is approximately in the plane of the rear face of said bar. A blade-spring 35 is applied to the front face of said bar and bears against the lower portion of the front face of the spur and normally holds the latter in its rearmost position. A pin 36 extends transversely through the heel of the spur in front of the bar 27 and serves to limit the rearward movement of said spur. To the crank-arm 11 is attached a cam-arm 37, which stands below said spur when the crank is in the upright or normal position. When the crank moves forward, said camarm engages said spur from below and lifts the latter and the bar 27 sufficiently to cause said bar to engage and tilt the lever 20, so as to lower the upper end thereof a little farther than it stood on account of its engagement so desired, the engagement between the camsaid hook 16 has been passed bythe crank-arm in order thatthe pawl 13 may promptly descend and be in position to prevent a second forward movement of the crank after reversal to the normal position if only the hook is used and to prevent a second forward movement after the crank-arm has passed the hook 15 if both hooks are used. The purpose of the hook 15 is to hold the crank-arm in its normal or locked position, and the purpose of the hook 16 is to prevent the operator from moving the crank forward to its limit and then partially reversing it and again moving it forward to its limit, and thereby repeating or prolonging the action of the vending apparatus. When the crank is reversed to its normal position, after it has been turned forward far enough to cause the cam-arm to pass said spur, said cam-arm engages the oblique face of said spur and presses said spur forward until said cam-arm has freed itself from said spur. Then said spring again presses said spur into its normal position.

Between the plates 5 and 6 and in line with the horizontal portion of the check-passage is the horizontal plunger 39, having on its outer end a head 40, normally resting away from the plates 5 and 6 a distance equal to the diameter of the check to be used in the apparatus, to the end that said plunger may be pressed forward into said check-passage a distance equal to the diameter of one of the checks. A suitable spring 41 is secured to the plate 6 by one end and has its free end engaged in a notch 42 in the plunger, said spring being under strain, so as to hold said plunger normally at its outer limit of movement. Said spring may extend through a gap 43 in the rib 18, said gap affording a space for movement for said spring and the portion of the rib at the outer side of said gap constituting a stop for said spring when the plunger is in its outer or normal position. Said gap may also serve as a passage for diverting checks which are too small to be engaged and held by said plunger. To the rear face of the plunger is secured a laterally-flexible pointed 6 and having the perpendicular face 45 and the oblique frontface 45. The space between the inner end of the plunger and the perpen- 'dicular face 45 of the hook is a little less than the diameter of the check in order that a check of the proper size descending through the chute will be caught and held by said hook, while a check of less diameter will pass downward between said face and the end of the plunger and through the gap 43. Behind said hook said rear plate 6 has a slot or cavity 46 opening through the front face of said plate from the inner portion of the plunger nearly to the free end of said hook, and from the latter point the front of said cavity is covered by a thin wall 47 for a distance equal to the range of movement of the plunger. Normally the extreme point of -the hook rests behind the wall 47 so that when the plunger is pressed forward the hook will be deflected rearward until it rests entirely rearward of the front face of the plate 6 and entirely out of the path of the check. hen the plunger is again returned to its normal position, the hook is again freed from the wall 47 sufliciently to bend forward into the path of the check.

Directly below the hook 44 is a horizontal laterally-yielding stop 48, the outer end ofwhich is secured to the rear plate 6 in a cavity 49 and the inner end of which stop projects obliquely into the path of the checks beneath the head of the hook 44 between the space occupied by the check when first received by said hook and the space occupied by said check when the latter has been driven forward by the forward movement of the plunger, to the end that said stop may stand behind the check when the plunger has completed its forward movement and serve to then hold the check against reverse movement while the plunger moves backward. The cavity 49 is long enough and deep enough to receive the stop 48 when the latter is pressed sidewise by the passing check.

It will be understood that, as shown in the drawings, the releasing apparatus does not become operative until several checks have been placed into the horizontal portion ofthe check-passage. It is obvious, however, that said horizontal passage may be shortened so as to require the presence of a smaller number of checks to render the apparatus operative.
