LAMSON CONSOLIDATED STORE I NEW JERSEY.

SERVICE COMPANY, OF NEWARK,

PNEUMATlC-DESPATCH-TUBE CARRIER.

SPECIFICATION forming part of Letters Patent No. 681,041, dated August 20, 1901. Application filed October 8, 1900.. Serial No. 32,328. (No model.)

To all whom it may concern.-

Be it known that I, J AMES'T. COWLEY, of

the rear end of the carrier, and another object is to prevent the insertion of the carrier into the tube until said cover has been locked.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure 1 is a view of one side of the cap or cover. Fig. 2 is a longitudinal section of i the rear part of the carrier, showing the devices for locking the cover to the shell of the carrier. 7 Fig. is a view of the outer side of cover. Fig. 4 is a longitudinal sectional view of the front part of the carrier, showing my improved bufier-head. Fig. 5 is a front view of the buifer-head with parts removed. Fig. 6 is a detail View hereinafter described.

Like letters of reference refer to like parts throughout the several views.

A represents the cylindrical shell of the carrier, which is made of sheet metal or other suitable material,and at its rear end the cover Bis hinged at O and is provided with a flange D, adapted when the cover is closed to fit around the outside of the shell of the carrier. Located in the center of the cap B is a gearwheel H, having a hub J, and located within said hub and wheel is a bolt E, the head of which, E, is on the exterior of the cover, and the nut G is on the interior of said cover and adapted when screwed up to securely hold the parts hereinafter described in position. Located around the hub J are three eccentrics K, K, and K separated from each other by suitable washers J, and located around said eccentrics are eccentric yokes L, N, and P,

respectively, which yokes are provided with bolts Q, Q, and Q respectively, and adapted .in their movements to be guided by the guides Q Q and Q Located on the inside of the cover B are lower and upper slides S S, adapted in their movements to be guided and supported by the supports S S S and S The slides S S are provided, respectively, with the teeth R R, which are adapted to engage with the teeth of the gear-wheel H and to be moved outwardly and inwardly by the movement of the arm F, secured fast on the bolt E, which bolt communicates movement to the gearwheel H and hub J, and by operating said arm the parts previously described are operated.

The cap or cover is shown in its locked position in Figs. 1 and 2, and upon the arrival of the carrier at the terminal the arm F is turned from the position shown in full lines, Figs. 2 and 3, to the position shown in dotted lines, Fig. 3, in the direction indicated by the arrow. This movement of the arm F will withdraw the bolts Q, Q, and Q from their locking position (shown in Figs. 1 and 2) inwardly from engagement with the flange D of the cover, and the continued movement of the arm F to the position shown in dotted lines, Fig. 3, will move said slides S S outwardly to the position shown in dotted lines, Fig. 3, so that said carrier cannot be introduced into the despatch-tube until the arm F has been moved to the position shown in full lines, Fig. 3, and the bolts Q, Q, and Q operated to lock the cover to the shell, at which time the slides S S will be withdrawn to their inner position within the circumference of the carrier-shell.

Secured to the front end of the carrier is a recessed plate T, having a recess T adapted to receive the nuts T of the bolts T which secure the plate T to the inner plate T, and between this inner plate T and the plate T is a packing of felt or other suitable compressible material. plate T is a packing T, such as leather, rubber, canvas, or the like, by means of suitable bolts or rivets T This packing-plate T and packing Tare of smaller diameter than Secured on the outside of the the plate T, so that when the packing T is compressed the plate and packing will be allowed to enter the end plate T against the compressible packing, and thereby cushion the shock of the carrier as it enters the terminal.

Having thus explained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to obtain by Letters Patent of the United States, is-

1. In a device of the character described, a carrier, a cover for said carrier, one'or more bolts for locking said cover to the shell of said carrier, an arm on the exterior of the cover and movable Within the circumference of the carrier-shell for operating said bolts to unlock and lock the cover, and means operated and moved by said arm beyond the circumference of the carrier-shell for preventing the introduction of the carrier into the tube when the cover is open.

2. In a device of the character described, a carrier, a cover for said carrier, one or more bolts for locking said cover to the shell of the carrier, an arm for operating said bolts and mounted concentrically on said cover, to lock and unlock said cover, and means operated by said arm for preventing the introduction of the carrier into the tube when the cover is open.

3. In a device of the character described, a carrier, a cover for said carrier, one or more bolts for locking said cover to the shell of the carrier, a concentric shaft carrying one or more eccentrics to operate said bolts, and an arm on the exterior of the cover and movable within the circumference of the carrier-shell and secured to said shaft and having its axis concentric with the cover.

4. In a device of the character described, a

carrier, a cover for said carrier, one or more bolts for locking said cover to the shell of the carrier, a concentric. shaft carrying one or more eccentrics to operate said bolts, an arm secured to said shaft and having its axis concentric with the cover, and one or more slides operated by said arm for preventing the introduction of the carrier into the tube when the cover is open.

5.- In a device of the character described, a carrier, a cover for said carrier, mechanism for locking-said cover to the shell of the carrier, an arm on the exterior of the cover and movable within the circumference of thecarrier for operating said locking mechanism to lock and unlock the cover, and means operated and moved by said arm beyond the circumference of the carrier for preventing introduction of the carrier into the tube when the cover is open.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 3d day of October, A. D. 1900.

JAMES T. COWLEY.
