PNEUMATIC CASH-CARRIER.

SPECIFICATION forming part ofLetterspPatent N 333,397, dated December 29, 1885.

Application filed October 2G, 1885. Serial No. 180,903. (No model.)

To all whom t may concern,.-

Be it known that we, WILBUR G. Davis and WM. M. HINMAN, citizens ot the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Pneumatic Cash-Carriers, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to improvements in apparatus for pneumatic cash-carriers.

The object of our invention is to improve on certain details of construction and lnethod of operating pneumatic cashcarriers, and more particularly of that class for whichLetters Patent ofthe United States were granted to Wilbur G. Davis, April 22, `1884i, No. 297,505, and also on the devices for which an application for a patent was tiled by the saine party May l5, 1885, Serial N o. 165,558.

Our invention consists in supplying the bellows at the cashiers desk with a series of nozzles or outlets corresponding to the number of pipes used for the various stations7 said outlets being provided with valves lwhich can be opened or closed, at the will of the operator,

vto direct the air-blast into any one of the pipes,

as will more fully hereinafter appear.

Our invention consists, further, of the peculiar construction of the transmitting-standards which support the main tubes, whereby the carrier is readily inserted and discharged from the tubes.

Our invention consists, further, in making the car or carrier oval or egg shaped at both ends, in order that it will accommodate itself to the curves of the tube, and also in providing it with apskirt or apron at the rear end, which is expanded, when the air-pressure is applied,againstthe sides of the tube,thus preventing the air from passing by the sides of the carrier.

Our invention consists, further, in placing lan open basket under the discharge and receiving end of the tube at the cashiers desk,

said basket being provided with a sack filled with lead shot, into which the carrier is discharged, and by which means the force of the carrier is broken without injurious effect to the carrier.

Our invention consists, further, in combining with the double tubes of the sales-station a curved chute or trough, into which the carrier is projected by the force of the air-current, the function of said trough being to break the force of the carrier.

Our invention consists, further, in certain details of construction, which will be fully described hereinafter, and pointed out in the claims.

Figure lis a view in perspective of the cashiers desk and the salesmans counter, showing the connections with the bellows and the tubes. Fig. 2 is a perspectiveview ofthe chute or trough for arresting the force of the carrier. Fig. 3 isa sectional view ofthe transmittingstandard with the carrier inserted therein, and also a sectional view of the receivingbasket and sack of shot. Fig. 4 is a sectional view of the bellows with the air-outlet and valve and rod for controlling the air-currents. Fig. 5 is a sectional view of the cash-carrier.

A indicates the cashiers desk,on which are securely mounted any desired number of transmitting-standards B, the number of stand- 75 ards B corresponding with the number o f stations at the sales-counters.

C is an ordinary forcing-bellowsv the top of which is firmly secured to the frame D, while the lower portion is free to be moved up and down by means ofthe treadle E. The treadle E is connected to the bellows by means of the cords F, which are secured at one end to the treadle and at the other end to the bottom of the bellows, the cords passing over the sheaves or pulleys G, secured to the upper or fixed end, H, of the bellows. The upper end of the bellows is provided with aseries of outlets or nozzles, I, which communicate with the transmitting-standards B by means of suitable ducts, K. The nozzles or outlets Iareprovided with hinged valves or doors L, which open toward the standards B, said valves being held in a closed position by means of the rods M: The rods M pass up th rough the counter A, and are provided with a knob, N, on which is placed a number corresponding with the number of the station with which this line of tubing oonnects. The rod M also passes through a chamber or cylinder, O, which is screwed or otherroo Wise secured to the plate P, said plate being attached to the upper side ofthe counter. YThe rod M is provided with a ball ortprojection,V R, Within the cylinder or chamber O, which impinges against the strap-spring S, located within said cylinder or chamber, so as to hold the rod either in its raised or lowered position. It will be noticed that when the rod M is raised the valveL is free to open outward by the pressure of air from the bellows; but when this particular line is not to be used the rod M is forced down, closes the valve,and holds the same ina closed position. The transmitting standard or tube B connects with the nozzles I, as already stated, aud is curved at its upper end, as shown in Fig. 3, terminating in head T, having an opening, U, passing therethrough.

To the upper end of the head T is secured the line of pipe V, said pipe being made of glass or other transparent material, such as is described and claimed in the patent above re` ferred to. The lower end of the head T is adapted to be closed by the valve W when the carrier is to be transmitted to a station, a

suitable cushion, A', of rubber or felt being secured to the st-andard to prevent the valve from striking against said standard.

The head T is provided with an interior annular recess, a, to receive theskirt of the cash-- it may readily conform to the curves of the tubes forming the line. The carrier B is divided into two parts and hinged at b, (see'Fig. 5,) the top or lid C being provided With a projection, c, which impinges against a spring, d, secured to the inside of the mai-n body of the carrier, and by which means the top is held either in an open or closed position, the front end or lid of the carrier being covered with felt e to protect it from injury.`

D is a skirt or apron of felt or other suitable material secured around the rear end of the carrier, and is arranged to dare outwardly, so as to impinge against the inside of ,the tube, to prevent the air from passing by the carrier.

In practice the carrier is placed in the head T. and pushed up until the skirt D rests on the ledge a. The valve W is now closed and the treadle operated to work the bellows. The air from the bellows passing up through the standard B comes in contact with the carrier B. and forces it rapidly to the station or other end of the line of tubing, Where it is caught bythe receiver E.

, standard or support, f, in which are pivoted F indicates the sales counter or station to which the tube V leads from the cashiers desk, one tube for each station. The tubeVat this end of the line is supported by a suitable the movable tube-sections g and h, said tubemore, the shot does not pack solid, as is the sections being joined together and both adapted to be brought under the end of the pipe V. The tube-section Lr/communicates with the bellows G, located under the counter F, while the tube-section h communicates with the pipe V and chute E at all times except when it is desired to transmit the carrier to the cashiers desk, then the tubes areswung on their pivots to bring the section g in communication With the pipe V.

These tube-sections and the manner of operating them are fully set forth and claimed in the application of W. Gr. Davis, above referred to, and need not be further described in this connection.

The chute E consists of a curved metallic shell open at the top, but having the upper edge projecting over to prevent the carrier from jumping out of the trough,isaid chute` being secured to the counter at the end of the tube-section h, and is adapted to stop or gradu-f ally breakthe force ofthe carrier. vAs the carrier emerges from the tube-section h, iti1n`-9o pinges on the curved inside of the trough,- which breaks its force and permits it to fall gently on the counter. i A l H is a Wire` basket, adapted to fit close"ATA against the standard B, the rear side of said basket being made higher than the front side, as shown. The bottom of the basket H is open and adapted to receive a pocket or bag,` I', of leather or other suitable material, said pocket being illed with lead shot to break the 10o force of the carrier as it is sent from the station to the cashiers desk.

In practice we have found that the lead shot contained in the pocket or bag is very effect-` ive in stopping or resisting the force of the carrier as it emerges from the tube, and does Y not injure or break the carrier, and, furthercase with sand and other material.-

In practice we may iind it desirable tofuse no the transmitting-standard B at both ends of the line-i. e., at the various stations, as Well as at the cashiers desk or central station.

Having thus described our invention, whatv we claim, and desire to secure by Letters Patx 15 ent, is-

l. In pneumatic cashcarriers, the bellows C, provided with a series of nozzles commu-y nicating with the transmittingstandards B,

said nozzles being provided with valves L, in 12o being adaptedto be closed by a suitable'va'lve, '13o whereby the carrier is readily inserted and f transmitted to its destination, as set forth. f 3. In pneumatic cash-carriers, the head' T,

provided with the groove or recess a, in com- D', as set forth.

6. A cash-carrier for pneumatic tubes, consisting of a metallic cylinder with oval ends, hinged in two sections, in combination with the spring d and lug c, as set forth.

7 A receiver for cash-carriers, consisting of a sack or other suitable receptacle filled with lead shot placed under the receiving-opening of the standard B, as set forth.

8. The plate P, having the cylinder O attached thereto, said cylinder being provided with a spring, S, in combination with the rod M, provided with theprojection R, whereby the rod is held in position, as set forth.

9. The rod M, provided with the projection R, and working against the spring S in the cylinder or chamber O, in combination wit-h the nozzle I and valve L, as set forth.

' 10. In a cash-carrier, the combination of the bent tube h with the curved chute or trough E', as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
