SPECIFICATION forming part of Letters Patent No. 662,771, dated November 27, 1900. Application tiled March 30,1900. Serial No. 10.774' (N0 mOdl-J To all whom t may 00in/cern:

Be it known that I, FREDERICK C. CUTTING, a citizen of the United States, residingat the city of Rochester, in the county of Mon roe and State of New York, have invented certain new and useful Im provementsin Pneu matic-Cash- (larrier Terminals, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in pneumaticcash-carrier terminals in which the passage of air through the air-tubes is auto matically controlled by the device or mechanism placed within the terminal and which device is pnt in operation to control the pasof air by the introduction of the cash box or cartridge into the airetube at the sales mans station and its return through the retu rn-tube to the same station or terminal; and the objects of my invention are, iirst, to control the passage of air through the tubes, so that when a cash-box is not being forwarded from and returned to the salesstation the passage ot' air will be stopped; second, to automatically control the passage of air th rough the air-tubes by the operation of the means hereinafter fully described, Which are putin operation by the introduction ot' a caslrbox into the receiving-tube at the saleslnans sta tion to the end that the passage of air may be continuous until the cash-box or cashboxes sent from such sales-station have been returned thereto, and, third, to reduce the amount of power required to operate a series of stations or terminals joined in one system.

I accomplish the above-mentioned objects by the mechanism herein described, and illustrated in the accompanying drawings, in which Figure l is an elevation or side view of my completeinvention. Portionsoftheairtubes, (which are of the ordinary construction and foi-111,) however, are cut away to more clearly show the invention which I claim as mine. Fig. 2 is a plan view of my invention. Fig. 3 is a sectional and side view of that portion of my invention which controls the opening of the valve and allows the passage of air through the tubes and is taken on line a: n; of Fig. 2. Fig. lis a vertical sectional and side View of that portion of my invention which controls the closing of the valve that stops the passage of air through the tubes. Fig. 5 is a side view of the receiving-tube for the cash-box,(portions ot' the case being cut away,) showing the lever device for raising the airvalve and the cam and lever for putting in operation the means employed to turn the ratchet-wheels, hereinafter described, to the end that the air shall have free passage through the air-tubes until all the cash-boxes sent from the sales-station have been returned thereto. Fig. 6 is a detailed view of the cam and latch engaged that control the movement of the sliding bar 5 in the direction of the arrow shown on the bar in Fig. 3. Fig. 7 is a detail view of the cam and latch shown in Fig. 6, with the latch released from its engagement with the cam; and Fig. S is a plan view of the said cam and latch, showing their relative positions to each other.

Similar letters and figures refer to similar parts throughout the several views.

A represents the air-tube, in which is deposited the cash-box to be forwarded to the cash-desk and is approximately of Y shape, one branch o'l the saine being closed by the lid d, which is pivotally connected to the handle b by pin o, and the handle b is pivotally connected to the tube by pin d.

B represents the air-tube for the return of the cash-box to the sales-station and is closed by the lid e, which is pivotally connected to the arm f by the pin g, and the armf connected to the head of the terminal by the pin 7L, and the lid held in position against the end of said tube by spring 1l.

C is an air-passage between the tubes A and B, its bottom being formed to receive one branch of air-tube A, one end being closed by partitionj and its top being closed by diac phragm or partition it, leaving the end atl open into the air-tube B. Theair in its pas sage through the above-described tubes travels in the direction indicated by the .arrows shown in Fig. l.

It will be observed that I erect posts l 2 3 4 on the upper surface of the diaphragm 7c and provide them with passage-Ways for the sliding bars 5 6, which are passed through the said openings and move freely therein. Above these bars and lying in the same direction are the pawls 7 8, respectively pivoted IOO to the said bars and thrown in contact with the ratchet-wheels 9 9 by means yof springs 10 10", placed beneath them and resting in holes in the top of said bars. The ratchetwheels 9 9' are secured to the same axle, and the teeth are cut to turn the wheels in opposite directions when acted upon by the different pawls 7 and 8, and in order to allow such opposite movement it is to be observedthatthe said pawls must not come in contact with the ratchet-wheels when the 'wheels are not being turned, and heuceI provide shoulders 11 12 upon the pawls, which come in contact with setscrews 13 14, which throw the pawls down from the ratchet-wheels when the bars 5 6 are forced backby the springs 15 16. The ratchet wheels are prevented from turning when the pawls are both thrown down by the friction of the axle-bearings or by a brake upon the wheels.

I place a valve 17 within the air-passage C over the end of the airtube A and secure it to a rod 18, passed vertically through the center, and support said rod in position .by bearings in the diaphragm 7a and the bar m, passed across said tube A. I terminate said rod at its top in a cone 1E), and immediately below this I cut an annular groove 20. Vhen the rod 18 is raised to t-he highest point, said groove assumes a position opposite the latch 21; but the latch is held back by a rod 22, passed between the ratchet-wheels, until a cash-box is placed in transit in the air-tube A, whereby themechanism putin operation turns the ratchet-wheels and releases said latch, which is then forced forward by the spring 2 and catches in the annular groove 20.

To lugs in the back of the air-tube A, I secure lever 24:, to the endof which is attached a strap 25, which is fastened near the center of lid a and made of suitable length to allow said lid to be raised and admit the introduction of a cash-box into the air-tube A and also to lift the rod 18 to a position in which the annular groove 2O is opposite latch 21.

Through the side of the air-tube A, supported in suitable bearings, I pass an axle 26 and project an arm 27 therefrom downwardly within the said tube until its end passes approximately half-way across the diameter of the space traveled by the cash-box. To the end of the said axle immediately outside the said tube I attach a cam 28. Upon this cam rests the foot of rod 29, which I pass vertically through the air-chamber C and up into the space above the diaphragm 7c. I tis to be observed that said rod passes through a coilspring 30 within the air-chainbe1'C,which rests down upon collar 31, secured to said rod, and acts to force the foot of said rod upon the cam 28 and to keep the end of the arm 27 projected into the passageway traveled by the cash-box within the air tube A when not forced back by the passage of a cash-box.

In the upper end of rod 2i) I provide a slot for the reception of the arm projected from cam 32 and pass said arm through said slot.

The cam 32 is pivotally connected in suitable bearings to the diaphragm 71;. Riding upon cam 32 is a latch 33, which turns upon an axle secured to sliding bar 5, whose office I will explain Inore fully hereinafter.

The bars 5 and 6 are `preferably made square or iiattened, so that they will always retain edgewise a vertical position. Bar 6 is turned up at one end, Vand to the side of such upturned end a small wheel 34 is attached and revolves upon an axle secured to said bar. I provide the axle 35, which is journaled in the sides of a hood projected inwardly from the wall of the tube B and the diaphragm 7e. To the axle 35, between the sides of said hood, I secure the arm 36 and project it across the center of the tube B into the space traveled by the cash-box. To axle 35 I also secure cam 37 within the space above the diaphragm c in a position so that the wheel 34 will travel in the slotI in said cam and operate Vto throw the bar 6 iu the direction indicated by the arrow thereon shown in Fig. et, when the axle is tu rued by a downward movement of arm 36, and return said bar to its normal position again by the action ofthe spring 16, which operates to revolve said axle in one direction.

Having now fully described and pointed out the various parts of my invention and shown their relative position and arrangement, their operation in combination is as follows, viz: When the lid a is raised to introduce a cashbox into the air-tube A, the valve 17, by the action-of the lever 24, is raised, the air-passage through'the air-tubes opened, and the annular groove 2O brought to a position opposite latch 21; but said latch does not engage itself in said groove by the raising of said lid a and does not retain the valve 17 in a position elevated from its seat on the end of the air-tube A, but leaves said valve free to drop down to its seat on said air-tube when the valve a is closed, unless a cash-box is introduced into the said air-tube and placed in transit. After the valve a, has been raised, as described above, the introduction of a cash-box into the .air-

'tube A forces the arm 27 back out`of the pathway traveled by said cash-box, whichin turn operates cam 28, which nieves rod 29 upward until the latch 33, actuated by cam 32, has moved the sliding bar 5 in the direction indicated bythe arrow on said bar (shown in Fig. 3) to a position in which pawl 7, thrown up by spring 10, engages with a tooth on the ratchetwheel 9, whereupon latch 33 releases its engagement with cam 32 and permits the spring 15 to throw sliding bar 5 back to its normal position, causing the pawl 7 to revolve the ratchet-wheels in the direction indicated by the arrow shown thereon in Fig. 3 the distance measured by the distance betweenthe points of any two consecutive teeth, thereby releasing latch 21 and allowing spring 23 to throw said latch 21 forward and engage itself in said groove 2O and support the valve 17 in a position elevated from its seat on the end of the air-tube A until the cash-box or cashboxes placed in transit inair-tube A have been returned to the' same sales-station from which they were sent. The eect of the introduction of a series of cash-boxes into the air-tube A would be that the introduction of each and every one would produce a similar action to that above described, each box causing the ratchet-wheels to turn in the direction indicated bythe arrow thereon (shown in Fig. 3) the distance measured by the dist-ance between the points of any two consecutive teeth. It is to be observed, however, that the introduction of any cash-box after the first of a series placed in transit in the air-tube A has no effect whatever upon latch 21, but from the time of the introduction of the first cashbox into air-tube A latch 21 keeps its engagement in groove 2O and holds the valvel' elevated from its seat on air-tube A until all of the cash-boxes of such series have been returned to such transmitting-station.

Upon return of a cash-box to the salesmans station when but a single box has been placed in transit the operation of the mechanism hereinbefore i described for controlling the closing of the air-passage is as follows, viz: A cash-box passes on its return through airtube B in the direction indicated by the arrow shown in Fig. 1 and in its transit comes in contact with arm 36, presses it downward, and turns axle 35, which operates cam 37, which is secured thereto, which cam in turn acts upon wheel 34 and moves sliding bar 6 in the direction indicated bythe arrow shown thereon in Fig. 4. The paw] 8 is thrown by spring l0 into engagement with a tooth of the ratchet-wheel 9 and turns it in the direction indicated by the arrow shown thereon in Fig. 4 the distance measured by the distance between the points of any two consecutive teeth, thereby bringing bar 22 in contact with the arm on latch 21, forcing said arm down and causing latch 21 to disengage itself from groove 2O and allow valve 17 to immediately close and stop the passage of air through the air-tubes, the cash-box opening the exit trap or lid e by action of gravitation after the said valve 17 is closed.

Itis to be observed that by the return of a number of cash-boxes of a series through the return-tube B it is the lreturn of the last one only of said series that causes latch 21 to lrelease its engagement with groove 2O and allow valve 17 to drop down and close the passage of air through the air-tubes. Itis also to be observed that I prevent the possibility of a cash-box entering the air-passage C by making the arm 86 just long enough to swing across the end of said passage-way, as shown by dotted lines in Fig. 4, at its intersection with airI tube B and provide a cushion 4:0 for said arm to strike against.

Having now fully described my invention and shown its operation, what I claim as my invention, and desire to secure by Letters Patent, is-
