INVENTOR.
' Harry Greenwald ATTORNEY United States Patent '0 COIN SLIDE WITH ROLLER OPERATING ARCUATE WING CAM Harry Greenwald, Brooklyn, N .Y., assignor to H. Greenwald Co., Inc., Brooklyn, N.Y., a corporation Filed Apr. 9, 1959, Ser. No. 805,260
12 Claims. (Cl. 200-38) This invention relates to coin controlled appliances and, more particularly, to a novel combination of a coin slide and a timer having an operating shaft extending at an acute angle to a perpendicular to the plane of movement of a coin slide.
In order to adapt an electrical appliance for coin controlled operation by a reciprocable coin slide, the timer shaft, or a coaxial extension thereof, is provided with a cam arranged to be engaged by an operator on the coin slide. The coacting cam and operator are enclosed in a locked coin receptacle so that initiation of the operating cycle of the appliance can be effected only by proper operation of the coin slide by one or more coins of the proper denomination.
As a usual case, the parts are so disposed that the axis of the timer shaft is perpendicular to the plane of movement of the coin slide. In such case, as well as 1n the case where the timer shaft axis is parallel to the plane of movement of the coin slide but perpendicular to the line of movement thereof, there is relatively little difficulty in designing the cam and operator for proper coaction.
However, some of the new appliances have a sloping operating and control panel, with the timer shaft perpendicular to such panel, the control panel usually sloping upwardly from a horizontal upper wall of the appliance. This horizontal wall forms a convenient mounting surface for a coin slide but, in such case, the timer shaft is then at an acute angle to a perpendicular to the plane of movement of the coin slide. In this case, design of a cam and operator for effective coaction presents very considerable difiiculties, particular where it is desired to use an essentially standard type of reciprocable coin slide.
In accordance with the present invention, such effective coaction is provided by securing, to the inner end of a standard reciprocable coin slide, an extension plate having a rearwardly opening elongated slot with a flared opening arranged to have guiding engagement with the timer shaft, or a coaxial extension thereof, when the coin slide is moved inwardly. The timer shaft extension is coupled coaxially to the timer shaft and has its upper or outer end engaged in an aperture in a support bracket or plate extending transversely of the coin slide housing, this plate having a spring extension or finger bearing against the coin slide.
The extension on the coin slide carries a depending roller rotatable on a vertical axis laterally offset from the slot, the roller having a larger diameter operating head. This roller, when the coin slide is pushed inwardly, engages an arcute wall or wing eccentric to the timer shaft extension on an axis parallel thereto, and extending upwardly from a radial plate rotatable on the timer shaft extension. The radial plate carries an adjustable abutment engageable with a radial arm fixed to the timer shaft extension, and a coil spring biases the, abutment to engage the radial arm. Thus,'as the roller engages and rolls along the arcuate wing, the time shaft is rotated to the cycle start position.
It sometimes happens that, due to an extraordinarily fast inward movement of the coin slide, the timer shaft is given such an impetus that it is rotated substantially beyond the cycle start position. To prevent this, a light fiat spring is secured to the coin slide extension and has a bent end extending through the slot. This bent end is engageable by a radial pin on the timer shaft extension to limit such advance of the timer shaft. Should the coin slide not be pulled outwardly, manually or by spring action, in time to avoid interference with timer movement, the radial pin will simply deflect and ride over the bent end of the fiat spring.
For an understanding of the invention principles, reference is made to the following description of a typical embodiment thereof as illustrated in the accompanying drawing. In the drawing:
Fig. l is a side elevation view of mechanism embodying the invention;
Fig. 2 is a plan view of the coin slide and the timer shaft extension;
Fig. 3 is a plan view of the timer shaft extension; and
Fig. 4 is a plan view of the wing cam.
Referring to Fig. 1, the coin control mechanism of the invention is illustrated as incorporated in a coin slide housing 10 mounted on a horizontal wall 11 of an appiance having a sloping control panel 12. The timer 13 for the appliance is mounted on the undersurface of panel 12 and has an operating shaft 15 projecting through the panel.
A reciprocable coin slide assembly, generally indicated at 20, is mounted in housing 10 and includes a guide structure 21 having a mounting plate 22 secured to the front wall 14 of housing 10. Assembly 20 further includes a relatively elongated coin slide 25 slidably mounted in structure 21 and biased outwardly by a tension spring 23 secured between a post 24 on guide structure 21 and a bracket 26 on slide 25. The coin slide assembly may be provided, in the usual manner, with the customary devices for preventing unauthorized operation by slugs, washers, and the like.
In accordance with the invention, an extension plate 30 is secured to the inner end of slide 25 by bolts 31, or may be formed integrally with the slide. Plate 30 has an offset 32 formed with an elongated rearwardly opening slot 33 having a flared entrance throat 34 and aligned with the projected axis of shaft 15. An eongated roller 35 is rotatably secured to depend from ofiset 32 and has an enlarged ball-shape lower operating end 36. For a purpose to be described, a light fiat spring 37, L-shaped in plan, is secured against the undersurface of plate 30 and has a bent end 38 projecting upwardly through slot 33.
A plate 16 is secured to extend between the side Walls of housing 10 in spaced substantially parallel relation to panel 12. This plate has an extension 17 hearing against the upper surface of extension 30, and counteracts any tendency of slide 25 or extension 30 to deflect upwardly.
Plate 16 has an aperture (not shown) coaxial with shaft 15 and rotatably receiving the upper end of an extension shaft 40 coaxial with timer shaft 15. Referring more particularly to Figs. 1, 3 and 4, the lower end of shaft 40 is semi-cylindrical, as at 41, so as to mate with the semi-cylindrical upper end of timer shaft 15 when the mating ends are enclosed in a coupling sleeve 42 secured to shaft 40. Adjacent the upper end of shaft 40, a radial pin 43 projects therefrom for engagement with bent spring end 38 when slide 25 is in its innermost position.
Below pin 43, and at the general level of the ball shape operating end 36 of roller 35, shaft 40 has a reduced diameter portion 44. Just below this portion, the cam, best seen in Figs. 3 and 4, is mounted on shaft 40. This cam comprises a flat radial plate 46 having an arcuate, axially elongated wing cam 45 projecting upwardly from plate 46 and having an axis in spaced:
parellel relation to the axis of shaft 40. Plate 46 is rotatably mounted between axially spaced flanges of a bushing 47 embracing shaft 40 and integral with a collar 50 secured against rotation on shaft 4t) by a set screw 51. A spring clip 48, seating against a shoulder on shaft 40, prevents axial downward movement of collar 56.
Plate 46 has a depending lug 52 to which a clip 53 is secured by a screw 54. Clip 53 has a curved lower end 56 which cooperates with lug 52 to receive an adjusting screw 55 bearing against a radial pin 57 on collar 50. A coil spring 58- has one end hooked over lug 52 and its other end hooked over pin 57', to bias screw 55 to engage pin 57. This provides a lost motion connection of cam 45 and shaft 40 in onedirection of rotation, with positive drive of shaft 40 by cam 45 in the opposite direction.
The mechanism operates as follows. In the cycle off position of the timer, arcuate wing cam 45 extends substantially radially of shaft 40 across the path of movement of roller 35, slide 25 with roller 35 being in the outermost position shown by broken lines in Fig. 1. When a coin is placed in slide 25 and the latter is pushed inwardly, the ball shape end 36' of roller 35 engages and rolls along wing cam 45 to rotate the wing cam and shaft 40 to the cycle start position. Should too much impetus be given to the'slide, pin 43 striking spring end 38 will momentarily halt the timer until slide 25 is pulled' outwardly. If the slide is no-tmoved outwardly, further timer motion will cause pin 43 to deflect spring end 38 and ride'over it.
While a specific embodiment of the invention has been shown and describedin detail to illustrate the applica tion of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
