To. all 'whom it may concern Be it known that we, FRnnERICK C.N1CKOL and MILTON C. STERN, citizens of the United States, residingat Dayton, in the county of Montgomery.- .and St-ate of Ohio,I have invented certain new and useful Improvements in Cash-'Drawerg of which the following is a specification, reference being hadl therein to the accompanying drawing.

This invent-ion relates to cash drawers, and more particularly to cash drawers which open automatically when released.

The object of the invention is toprovide a drawer of this character with actuating and cont-rolling devices which will open the drawer quickly and will Start and stop the same without appreciable ljarl thereby-overcoming the fault, common 1n drawers of so suddenly that the cashinthe drawer will be displaced.

It is also an object of theninvention to rovide means for regulating the controlling devices; and further, to construct the whole mechanism in such la. simplev durable man ner that there will be smallliability of iti being broken or rendered inoperative.

In the accompanying drawin s, Figure 'l is a horizontal, sectional view, ta.A en through the casing of the drawer above the drawer itself; Fig. 2 is a longitudinal, sectional view, taken on theA line a: a' of Fig. 1 and looking in the direction of theV arrows; and

Fig. 3 is a detail view of the regulating devicefor the controlling mechanism.

In these drawings we have illustrated one embodiment of our invention and haveshown the same as applied to a cash drawer comprising a drawer frame l and a drawer proper 2 which is of a size somewhat' smaller than the frame l and is divided into compartments. The frame carrying the drawer 2 is mounted inA a suitable casing?) which is here shown as a special casing built particularly for the drawer and adapted to have mounted upon it an autographic register, the whole to set upon a. counter or other suitable support. It will be understood, however, that this particular formofdrawer and casing are -chosen for the purpose of illustration only and that vthe invention is applicable to various drawers and that these may be mounted in casings of various kinds whether built into a counter or independently thereof. The drawer is preferably inthe casing in such a manner as to reduce to a minimum the friction between the drawer and the casing and to cause the drawer to work as easily as possible. As h ere shown the drawer is provided on both sides with rollers 4 which travel on suitable tracks, `These track are shown as comprising two metal bars 5 arranged one above the other and spaced apart to receive rollers, winch preferably have annular grooves to receive the adjacent edges of the bars constituting the track. Preferably, there are` two rollers on each side of the drawer, one arranged near the extreme rear end ofthe frame. l and the other arranged near the rear end of the drawer proper Y2. This arrangement permits. thev drawer to open to substantially its full depth and alsoresists any tendency of the drawer to tip when in its open pos1tion..

Gutward .movement, may beimparted toA the, drawerjin any suitable manner. Usually, however, .this is accomplished by the use of one orA more springs, land, in the present -ineoI stance, e employ two springs for this puri pose hich are here shown as ordinary" colle springs 6 connected at theirrearends `to hooks .77extending upwardly from the rear portion of the drawer frame'l. and con` uected at their forward ends .to hooks 8 secured to the front portion Aof the casing.' A suitable catch is provided to retain the 'drawer in its closed position, which,as.here shown, comprises a dog 9 havinga tapered nose 1 0 adapted to extend infront of the -rear ort-ion of the drawer proper, which may be provided with a part cooperating with tbe nose, suoh as a metal plate 11. A spring ,12 confined between the dog 9 and 'the top of the casing holds the dog normally in its lowermost position, causing the nose .to engage thedrawer and retain the same in its closed position. The drawer may be released in any suitable manner. I i the particular type of mechanism here illustrated, however, we provide the dog with an arm 13 extending beyond the pivotal 'center thereof and providedwith a rod 14 which extends through the top of the casing to enable the dog to be actuated from the ex terior of the casing to release the drawer.

When the dog has been thus actuated the springs will move the drawer into its foremost position, and, when the drawer is pushed to its closed osition, the rear edge thereof will engage t e beveled nose of the dog and force the same upward against the tension of the spring 12 to permit that portion of the drawer carrying the plate 11 to pass beyond the same.

If permitted to operate underthe influence of the springs 6 withoutpontrolling devices of some sort the drawer 'would stop` so suddenly that the coins in the coin compartments would be thrown out of saidcompartments. To eliminate this sudden stop and the accompanying jolt we provide an air-controlled device to regulate the outward movement of the drawer. As here shown this device comprises a pneumatic cylinder 15- rigidly secured to the casing 3 above the drawer. Mounted within the cylinder is the usual piston 16 having a piston rod 17 which extends rearwardly beyond the end of the cylinder and is connected to the rear portion of the drawer frame 1, this A connection being formed in the present instance by providing the rear end of the piston rod with an eye or loop 18 to receive a pin 19 carried byr a/.bracket4 20 secured to the drawer frame 1.n Any suitable device, such as a cotter pin 21 may be employed to retain the loop upon the pin. The cylinder 15 is provided at its forward end with the usual relief port 22 and means are provided for controlling the escape of the air from this port and thereby regulating the movement of the piston 16 and the speed at which the drawer opens. To this end a bushing 23 is mounted in the casing 3 in alinement with the relief port 22 and has its central opening screw-threaded. The inner end of the bushing is provided with a transverse passage 24 communicating with the port 22 of the cylinder and connected at one end with a longitudinal passage 25 extending to the outer end of the bushing. A pin 26 having a screw-threaded portion 27 is mounted in the bushing and has its inner end tapered to enter the port 22 and control the passage of air through the same. By adjusting this pin relatively to the port the movement of the piston may be controlled. The outer end of the bushing is preferably closed b means of a plug or cap 28, and, in order t at this cap may not prevent the air from escaping from the passage 25, the bushing is provided with a notch 29 which enables the air to pass about the edge of the cap. It is necessary, however, that cash drawers and drawers of a similar character should-open with a fair degree of speed, and, if the port 22 of the air cylinder is so adjusted as to permit the drawer to open with a fair degree of speed, the drawer will stop with a slight jolt, although this jolt will be muchV less than would be the case if the air-controlling mechanism were not used. In order to eliminate entirely the jolt at the end of the outward movement of the ldrawer we have provided a supplemental cushioning device which comes into play asthe drawer approaches the outward limit of its movement and cushions the final movement of the drawer. In the present construction this supplemental cushioning device comprises a relatively soft spring 30 mounted on a rod 31 rigidly secured to the rear wall of the casing near the bottom thereof, extending loosely through the rear portion of the drawer frame and to a point near the forward limit of movement of said rear portion of the frame. `The spring is preferablya coiled spring of ordinary construction and is held against outward movement by a nut 32 screw-threaded onto the end of the rod 31. A washer 33 is loosely mounted on the rod in the rear of the spring and is thus interposed bet-Ween the spring and the contacting part of the drawer frame. It will be apparent, therefore, that when the drawer is released and moved` forward by the action of the spring this movement will be controlled by the air cylinder and piston which will allow the drawer t0 move forward at a predetermined rate of speed only; and it will further be apparent thatvas the drawer approaches the outward limit of its movement the supplemental cushioning spring will be engaged by the drawer frame and will serve to cushion the final movement of the 'drawer and will absorb any jarincident to the stopping thereovf. Further, it will be apparent that the devieeisl of a very simple -construction `which will not readily become disarranged-orj broken, and, after the reliefport-kfor vthe :cylinder has once been adjusted, 4the device l will require no attention' 'whateverg f Itwill also be noted that thel piston is atfall' times within the cylinder and acts upon thev drawer from` the very beginning of its movement to the end thereof. Consequently, the drawer does not start with a jerk but withQa `slow easy movement. y v.

While we have shown and describel one form of our invention we wish itfto understood that this has been-chosenA for the purpose of illustration only andv that we do not desire to be limited to the details of con# struction shown and described, for obvious modifications will occur to a person skilled in the art.
