CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 713,060, dated November 11, 1902.

Application iled March 26, 1902. Serial No. 100,027. (No model.)

To a/ZZ whom, t may concern.-

a citizen of the United States of America, re-

siding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cash-Carriers, of which the following is a specification.

My invention relates to certain new and useful improvements in cash-carriers of the type wherein a closed box-carrier slides upon suitably-suspended rails, being propelled by a suitably-driven cable substantially in line with the rails.; and its object is to produce a cash-carrier of this type which shall be cheap, light, and simple for use primarily in connection with an entire system of this typo of store-service designed by me, but also capable of use in otherl systems of thesame general type. Y

To these ends my invention consists in certain novel features of construction, which are fully vdescribed herein and illustrated in the drawings.

In said drawings, Figure lis a front elevation of my improved carrier upon the track and the jaws grasping the cable. Fig. 2 is a front elevationshowing how the carrier is placed on the track. Fig. 3 is a front eleva' tion showing the jaws about to grasp the cable. Fig. 4 is a section through the sliding member in the line 4 4 of Fig. 5. section in the line 5 5 of Fig. 2. Fig. 6 isa section in the line 6 6 of Fig. 5 looking downward. Fig. 7isa section in the line 7 7 of Fig. 5, and Fig. 8 is a plan view of the cashcarrier. y

Referring to the drawings,` A A are two rails, preferably circular in cross-section, upon which the car runs and which are supported or suspended as may be desired.

.B is the box of this carrier. ably constructed of metal in the particular way shown herein. In this construction two side pieces b b are used, and they are carried down below the desired lower line of the box and .sharply recurved, as shown in cross-section in Fig. 3, therebyforniing lugs b', ex.

tending below the lower line of the box. The bottom of the box consists of a single piece of Fig. 5 is a.

. sheet metal b3,bent downward on the two sides J Beit known that1LWILtIAM LCHURCHILL,

to form downwardly-projecting portions 194194, which are inserted in the space left within the lugs b by the recurving of the sides, and they are there riveted or otherwise secured, as desired. The end pieces of the box b5 b5 are riveted to the ends of the side pieces b b, which are bent over upon the front and the rear of the box for this purpose, as is clearly shown in Fig. 6. The top C of the box consists of a plate of metal hinged at c to th-e top of one of the side pieces, and it is provided with a coiled spring czgwhich tends to open it. Upon the edge of the cover opposite to the spring is a loop or lug c3, adapted to engage a spring-catch c4 on the inside 0f the box, this catch when in engagement with the loop or lug keeping the cover closed against the force of the spring c2. The springcatch c4 can be reached and released through a hole c5 in the side of the box.

In order to prevent the box from rattling and jangling when running along the rails, it is desirable to provide a non-metallic surface for contact with the tracks. For this reason a plate D, of gutta-percha or some similar compound, is secured upon the bottom of the box B between the lugs b b' and is secured in place upon the box as may be desired. It will be observed that this plate comes into contact with the rails, and all vibrations which pass to the box must necessarily pass through it, their eifect being consequently greatly lessened. In systems of this general type the cash-carrier travels in all positions upon the rails. It may be inclined at any angle, it may run vertically, and it may run upside down, hanging from the rails. In order to act well in all these positions, there must be provided some special'means for keeping the carrier upon the rails. The system which I have adopted consists in the use of movable hooks extending downward from the sides of the box and under the rails, so as to keep the box in position, these hooks beinglaterally movable to permit the box to be placed upon and removed from the rails at any point, as may be desired. The particular construction of this device is clearly shown in Figs. 5, 6, and 7. The plate D upon the bottom of the carrier is provided with a shallow slot (l, running across the whole width of the plate at its center. In the bottom of this slot is cut a groove d', the relative length of which with respect to the slot d is clearly shown in the section shown in Fig. 7. The two hooks which engage the track (designated by the reference-letters E E) are provided with inwardly-extending flat portions e e, which run in the slot d and almost meet at its center. The hooks extend downwardly along the sides of the carrier to a point some distance below the bottom and thence inward, ending in the heavier portions e e, having the beveled surfaces c2 e2. The dat inwardlyextending portions e e have each a downwardly-stamped tongue c3, which enters the groove d in the center of the slot d. It will be seen that if the hooks E E are pulled outward these tongues will eventually come in contact with the ends of this groove, thereby limiting the lateral motion of the hooks. These tongues are connected by a spring e5, which tends to draw the hooks together and normally holds them in contact with the sides of the box. The hooks, however, may be readily drawn apart, either by hand or by any spreading mechanism, to permit the carrier to be removed from the rails, and they are also spread apart in placing the carrier on the rails, as is shown in Fig. 2. In placing the carrier on the rails it is placed over one of them and the beveled portion c2 of one of the hooks is placed upon the opposite rail, and the box is then pushed downward. The wedging action of the rail upon the beveled surface forces the hook outward and the box slips readily into place, the hook springing back im mediately and securing the box firmly upon the rails. I consider this mechanism for holding the carrier upon the rails particularly desirable, for it permits the box or carrier to be placed upon and removed from the rails at any point in their length. Upon the front of the box B is the cableengaging portion of this device and its construction and operation will nowl be described. It consists, broadly, of a slide F, moving vertically upon the front of the box B, and jaws connected thereto, the connection being such that when the slide is depressed the jaws will reach downward and grasp the cable, and when the slide again .rises this motion will be reversed and the jaws will open, release the cable, and return to their first position. The moving slide F is yoke-shaped, as shown, and consists of an upwardly-extending portion f, a cross-piece f', and two downwardly-extending portionsf2f2. The upwardly-extending portionfis slotted, asshown, to receive a latch f3 of the form shown-in Fig. 4, and a springj', which holds the latch i normally in the position shown in Fig. et. This latch is adapted to engage a pin f5 upon the front of the box B, as shown in Fig. l, and when in that position is adapted to lock the slide F in its lower position. The slide can be raised to its original position upon depressing the latch.

Upon the front of the box are pivoted two rotatable members G G, each having three radial arms g g, g g', and g2 g2. The members G G are pivoted upon projecting pins DG b of the box. The arms q2 g2 are connected by a coiled spring g3, as shown, which tends to hold the members in the position shown in Fig. 2, where the arms g2 g2 are in line with eachother and where the pivots 17 h6, the

arms g2 g2, and the spring g3 form a straight line. The arms g g are provided with pins g4 g4, extending backward toward vthe box and engaging slots ff jf in the downwardly-projecting portionsf2]c2 of the yoke-shaped slide F. The effect of this connection is that downward motion of the slide will rotate the inem bers G G against the force ofthe spring g3 in the direction shown by the arrows in Fig. 2. The position shown in this figure is the uppermost position which the slide F ever occupies, and to this position it tends normally to return on account of the tension ofthe spring g3 upon the arms g2 g2 of the members G G. To the arms g g of the members G G are pivotally connected jaws H H by means of pivots g5 g5. These jaws are pivoted together near their center by a pivot h, passing through them. Motion of the arms g g' in the direction of the arrows of Fig. 2 causes the ends of the jaws to traverse the path indicated by the dotted lines in Fig. 3that is, the jaws swing downward, drawing together until the points b, g5, and 72, are in a straight line, and when the point g5 passes this straight line the motion changes to one that is together and upward. In other words, the jaws swing downward, keeping a considerable distance apart, and then change their motion to one together and upward and grasp the cable and draw it to the position shown in Fig. l. This rotating motion ofthe members G is secured, as before explained, by downward pressure upon the slide F-that is to say, when it is desired to pick up cable the slide is pushed downward, the members G are rotated, the jaws swing downward, grasping the cable and drawing it upward to the position shown in Fig. 1, which is the position of all the mechanism when the car is in motion. When the slide reachesits lower position, the latch f3 catches upon the pinf5 on the box and holds the slide in this position, and thereby keeps the jaws in engagement with the cable. When it is desired to drop the cable, the latch f3 is pressed inward, pret'- erably by a cam above the track. The force of the springg3 produces reverse rotation of the members G G and consequent separation of the jaws and raising of the slide. The cable is released, therefore, and all the parts return to the position shown in Fig. 2,wherein the box is shown as being placed in position IOO IIO

i"fianco on the track. I consider this a particularly desirable form of cable-grasping mechanism, for the reason that the jaws are normally apart, and they swing downward, converging meanwhile upon the normal position of the cable. `Even if the cable is some distance out of its proper position the jaws will meet it, pull it into the normal position, grasp it,

and raise it, as heretofore described. There is another advantage in this type of construction in that it is not necessary to have any -extra tension upon the cable at the points of front portion of the cover C is a notch o8, 'soarranged'tha't when the slide F is'in its upper position the slot and the pin are equidistant from the hinge c' of the cover. Therefore when the cover is opened, the slide being in its proper position, the slot o8 will pass over the pin f6, permitting the cover to be opened. When, however, the slide is down in the position shown in Fig. 1 and the car is in motion, the pin and the slide occupy the relative vpositions shown in Fig. l, and the cover cannot be opened. The spring and latch of the cover, which'have been heretofore described,are normally quite sufficient to keep the carrier closed; butgreat annoyance has been caused in systemsof this kind owing to lthe fact that the spring and catch occasionally jar loose 'and the con/tents o f the box are scattered broadcast through' the store. l My device effec'tually prevents anything of this sort.. I

I realize that considerable changes can be made in the details of this construction, andy I do not intend to limit myself to the specific forni herein set forth.
