FEEDING AND WINDING MECHANISM.

Specification of Letters Patent.

Patented July 18, 1916.

Application file d March 9, 1912. Serial No. 682,744.

To all whom t may concern:

Be itl known that I, VALTER LEwIN, a subject of Great Britain, and a resident of the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Feeding and Winding Mechanism, of which the following is a specification. v

The invention relates to feeding and winding mechanism and more particularly to a mechanism adapted Vto be used in a taximeter for feeding a tape past a given point in a certain manner and a take-up reel for said tape.

The object of my invention is to provide means for feeding a tape or tapespast. a given point in a certain manner by the movement of and preferably by the reciprocation of a handle. I

Another object of the invention is to provide a reel on which for a given movement of the handle a fixed amount of tape is wound regardless of. the diameter of the accumulated roll of tape.

Another object of the inventionvis to provide a reel which revolves in one direction under the reciprocation of a handle.

Another object of the invention is to pron vide means for preventing the movement of the tape at certain times in the operation of the device.

This device 4possesses other advantageous features, which, with the lforegoing will be set forth at length in the following description, where I shall outline in full that form or embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification.` The novelty Vof the invention will be included in the claims succeeding said description. From this it will be apparent that I do not restrict myself to the showing made by such drawings and description as I may adopt many variations within the scope of my invention as eX- pressed in said claims.

Referring to the drawings: Figure 1 is'a plan view of the feeding and winding device of my invention mounted upon a supporting plate which is partly broken away. Fig, 2 is a detail of an elevation partly in section showing the handle connection and other features of the device. Fig. 3 is an elevation partly in section showing the winding rreel and the means for operating it. Fig. 4 is a detail showing the means forpreventing the reverse'movement of the handle before it has reached the end of its throw in either direction. j i

The present device is particularly adapted to be used in taXimeters for use on vehicles as disclosed in my prior application, Serial Number 641,636, filed July 31, 1911, wherein the length of the trip in miles, the timerof duration of the trip, the cost of the trip andother data' is printed upon a plurality of tapes,Y one of which is severed above the imprint thereon and delivered to the passenger, and the others wound on a take-up reel. In operating the device in connection with a taXimeter the data upon the printing wheels, atthebeginning of a trip, is imprinted upon the tapes, the various items being spaced apart on the tape. The tape is then moved a slight distance to'remove the printed items from below the printing point :of the. printing wheels, but not a suffi'- cient distance to bringnthe imprint from` one printing wheel .to position under the neXt. The distance of this movement is generally about three eights of an inch, thereby causing the initial and final imprints of each vprinting wheel vto lie adjacent each other. At the end of the trip the printing device is operated to imprint the final data on thev printing wheels onto the tape and the tape is then advanceda suitable distance so that the printed section of one tape may be cut off in the form of aticlret and presented to the passenger, the other tapes being accumulated in the reel.

In the drawings I have shown three tapes 2-3-4, but it is evident that the number of tapes may be varied depending upon the number of records desired. The tapes 2-3, are provided on their faces remote from the printing wheels with a coating of carbon or similar printing substance which produces the impression respectively on tapes 3 and 4 at the stamping operation. The tapes 2, 3, 4 are arranged respectively upon the supplyreels', 6, 7 which are readily removable so that they may be reloaded.' The reels are heldfrorn revolving freely by the springs 8 engaging their upper surfaces so that the withdrawntapes are heldl taut under ten sion. From the supply reels the tapes are drawn over an idler 9 to a position adjacent the printing Wheels indicated at 12; by the feed rollers 13-14. The feed rollers 13, 14 are of a length preferably equal to or greater than the widthv of the tape and are covered CID with rubber or some similar substance so that they may obtain a firm grip on the tapes. These feed rolls are preferably formed with a. crown face so that they always act to hold the tapes in central and alined position. After passing the feed rollers, the tapes 2-3 pass over the roller 15 onto the take-up reel 16, and the other tape 4 moves downward so that it maybe readily severed above the printed area.

The feed rollers 13-14 are operated by the movement of the handle 17, which lies on the outside of the taXimeter within convenient reach of operator, through the gear 18 loosely mounted on the'hollow shaft 19, the Aidler gears 2'1-22-23 and the gears 24,-25 on the feed rollers.

In the construction shown, the handle 17 is moved back and forth in the are of a circle in order to accommodate the stamping mechanism of the taXimeter and consequently means must be provided for causing a movement of the tapes in one direction for this reciprocating motion. This is accomplished by a construction which will now be described.

The handle 17 is securely attached to the hollow shaft 19 on which the take-up reel revolves and to which is also attached the arm 26, so that the handle and the arm move simultaneously. Mounted on the arm 26 is a toothed. quadrant 27 which engages the gear 18 loosely mounted on the shaft 19, so that the gear 18 revolves under the action of the arm 26, only when the quadrant is in locking engagement therewith. The quadrant is provided with a slot which engages a pin 28 on the arm 26 which holds it locked in one position, and is also provided with a light spring which tends to turn the quadrant to the right as shown in F ig. 1. When the handle 17 and, therefore, the arm 26 is moved from right to left the quadrant will rotate and become disengaged from the gear 18 and will not operate to advance the tapes. Then the handle is moved in the opposite direction, however, the quadrant is moved into mesh with the gear and being held stationary by the pin 28 causes the gear 18 to be moved with the handle. The motion of gear 18 is transmitted to the feed rollers and causes the tapes to be advanced. Provision is made, however, for producing a slight movement of the tapes by the movement of the handle toward the left, the reasons for such movement having been heretofore set forth. This is accomplished by means of the plate or disk 29 being rigidly attached to the shaft 19 so that it moves in unison with the handle, and preferably arranged below and spaced apart from the gear 18. The disk 29 is provided on its upper face with two pins 31-32 which in the reciprocation of the disk 29 engage the arm 33 of the slide 34, which is capable of limited longitudinal movement under the action of the pins 31.--32 The slide 34 is provided with a toothed member 35 which engages a pinion 3G mounted upon the back plate. Mounted upon the same shaft and above pinion 36 is a pinion 37 which is in mesh with gear 18. The lower pinion 3G is provided with a ratchet which is engaged by a spring held pawl 38 arranged in pinion 37, which allows the pinion 36 to more in one direction independently of pinion 37, but causes them to move simultaneously in the other direction. The pin 31 is arranged so that it contacts with and causes the movement of the slide 34 to the right as the handle approaches the end of its throw at the left. The movement of the slide to the right turns the pinion 36 to the right Vand causes la similar movement of pinion 37 which operates through the connecting gears to advance the tapes a slight distance.

/Vhen the handle reaches its eXtreme left position, a projection on the disk 29 engages a spring held arm 39 and moves a finger 41 on said arm into contact with gear 21 thereby preventing the further movement of the gear and preventing the momentum or tension in the parts from advancing the tapes an excessive distance.

The slide 34 is prevented from being moved backward by the friction of the parts in the reverse movement of the handle by means of the linger 42, carried by the fiat spring 43. When it becomes desirable to move the slide to the left, the pin 32 engages and presses upward the arm 44 attached to thespring 43, thereby moving the linger 42 out of contact with the slide. In its further movement, the pin 32 engages the arm 33 of the slide 34 and moves the slide to the left. 4This operation takes place as the handle approaches its extreme right position. During the motion of the handle from left to right the quadrant 27 engages the gear 18 and causes the tapes to be advanced a suiicient distance to move the printed area past the feed rollers, so that tape 4 may be severed to produce a ticket. As the slide reaches its eXtreme left position the linger 45 engages gear 18 and prevents the rotation thereof until the slide is again moved to the right. The movement of the handle to the left, therefore, operates to advance the tapes a slight distance and the movement to the right operates to advance the tapes a longer distance.

The record tape or tapes which remain in the meter are taken up on the take-up reel 16. Since the tapes are advanced b v the feed rollers, an equal distance at each complete operation and the diameter of the roll on the take-up reel varies with the amount of tape thereonl some provision must be made for keeping the tape taut on the rcel regardless of the amount of tape already ac- 11 cumulated. This is accomplished by 'placing a coiled spring between the reel and its turning means, which operates to overcome these variations. In this particular instance, since the handle is reciprocated, some means must be employed which operates to cause the reel to move in one direction only. The reel is preferably mounted in a bracket 46 the upper arm 47 of which is readily removable, so that the reel may be removed and the accumulated record tape removed. The winding element 48 of the reel, which is provided with fianges on the ends is revolved by the handle by means of the shaft 49. This shaft is provided' on its upper end with a gear 51 which transfers the motion of the shaft to the casing 52 through the gears 53-54 and 55, gear 55 being fixed to the casing 52. The winding element 48 of the reel is provided with a neck 56 extending into the casing 52 and is connected to the casing by means of a coiled spring 57 lying within the casing. The effect, therefore, ruf-'moving the handle is to revolve the casing, thereby putting the spring in tension which causes the winding element 48 or the reel proper to revolve. Arranged on the arm 47 is a spring held pawl 66 which engages the gear 51 and prevents a reverse movement thereof under the action of the spring 57. As the tape accumulates on the reel it is evident that the reel will revolve through a shorter arc to wind the same length of tape than it would if the reel was comparatively small. Should the movement of the casing be greatlyy in excess of the movement of the winding element, on account of the winding element being held by the record strip and the spring becomes tightly coiled, the handle may still be operated to advance the tape without moving the casing. This is accomplished by means of a frictional connection between the handle and the shaft 49. This frictional connection consists of a cone 58 mounted upon the shaft 49 and bearing in a conical cap 59 which is in engagement with the handle. The end of the shaft 49 is threaded and is provided with a thulnb nut 61 which bears against the cap 59 so that the grip of the frictional contact may be varied.

In the construction shown, in which the handle is reciprocated, provision must be made for causing the shaft 49 to be revolved in one direction only. This is accomplished by providing the cap -59 with a ratchet 62 which is engaged by a spring held finger 63 attached to the handle'. A movement of the handle in one direction, therefore, rotates the cap 59 and causes the casing 52 to turn and in the movement of the handle in the opposite direction the finger 63`rides over the ratchet 62 and does not rotate the cap 59. Provision is also made for preventing the handle from being moved in one direction until it has completed its throw in the other direction. This is accomplished by means of a segmental ratchet 64 securedto the back plate behind the handle. On the handle is pivoted a pawl 65 one end of which engages the ratchet 64, and to the other end of which is connected the tension spring 67 which alines the pawl with the handle when it is not engaging the ratchet. The movement of the handle isv stopped at the ends of the throw by the lugs 68 on the back plate, and the ratchet terminates in advance of the lugs 68, so that when the handle is in its end positions the pawl is alined with the handle and out of engagement with the ratchet. A movement ofthe handle away from the lug causes the pawl to engage the ratchet and prevents a backward movement of the handle.

-Means are also provided for severing the tape 4 below the feed rollers 13-14 to pro'- duce the ticket. The frame 69 which acts as a bearing for the upper ends of the feed roller shafts is provided with a blade 71 of greater length than the width of the tape. A similar blade 72 which forms the other side of the shear is mounted upon a slide 73 and is movable so that its edge passes the edge of blade 71. The tape 4 passes between the edges and when the blade 72 is moved forward a suiiicient distance it severs the tape. The slide 72 is moved forward by the bell crank 74, the outer end of which is engaged by the spring held pawl 75 arranged On the under side of plate 29. After being moved by the pawl the slide is returned to its original position by the spring 76. The pawl is preferably located in such position on the plate 29. that it passes the bell-crank immediately before the handle contact with the stop 68 at the end of its throw to the right. The initial movement to the left therefore operates to sever the tape.
