UNITED STATES PATENT OFFICE.
OTTO S. PIKE, OF MALDEN, MASSACHUSETTS, ASSIGNOR TO THE AMERICAN PNEUMATIC SERVICE COMPANY, OF DOVER, DELAWARE.
TERMINAL FOR PNEUMATIC-'DESPATCH APPARATUS.
SPECIFICATION forming part of Letters Patent No. 683,141, dated September 24, 1901. Application filed December 10, 1900- Serlal No. 39,266. (No model.)
To to whom it may concern:
Be it known that I, OTTO S. PIKE, of Malden, in the county of Middlesex and State of Massachusetts,have invented certain new and useful Improvements in Terminals for Pneumatic-Despatch Apparatus, of which the following is a specification.
This invention relates to improvements in pneumatic=-despatch apparatus; and its object is to facilitate the admission of sliding carriers into the transmission-tube by pro viding rollers in said terminal, so that the en trance of heavy carriers into the transmis sion-tube is easily effected.
My invention relates to 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 longitudinal sectional view of a I portion of a sending-terminal, showing the Valve in said terminal used for the insertion of the carrier. Fig. 2 is a cross-sectional view on the line X X lookingin the direction indicated by the arrow.
Like letters of reference refer to like parts throughout both views.
A represents a sending-terminal of a pneumatic-despatch-tube apparatus, and B shows a rotary valve having the passage 0. The valve 13 after the carrier has been inserted into the transmissiomtube is closed and the pressure is allowed to enter the tube to drive the carrier to the other end. In the bottom of the terminal A and also in the valve B there is arranged a series of rollers D, having bearings E in metallic strips F, located in the recess G. With the parts in the position shown in Fig. 1 the sliding carrier is inserted by the attendant into the right-hand end of the terminal A,and being given a slight push passes rapidly over the rolls in the bottom of the tube beyond the valve B. The terminal may be inclined, if desired, to facilitate the rolling of the carrier. The space between any two contiguous rolls beingless than the length of the gaskets on the oarrier,the carrier is not stopped in passing over said rolls. The rolls D have a curved contour,
of the carrier fits the shape of the rolls D. On opposite sides of the terminal A and in the valve B there are located series of rolls so that the gasket H, arranged horizontally,with their bearings I and J in vertical position and located in the metallic strips K in the recess L. These side 55' rolls also facilitate the entrance of the carriers by reducing the friction common to slid ing carriers, especially where the carriers are unevenly loaded and tend to bear on one side or the other of the tube.
Having thus ascertained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is
1. In an apparatus of the character described, a terminal into which sliding carriers are inserted for transmission, and means in said terminal for reducing the friction between the sliding carrier and the terminal.
2. In an apparatus of the character described, a terminal, antifrictionrollers in said terminal for reducing the friction between the carrier and the terminal.
3. In an apparatus of the character described, a terminal, and antifriction-rollers located in the bottom of said terminal for reducing the friction between the carrier and the terminal.
.4. In an apparatus of the character de scribed, a terminal, and antifriction-rollers having concave surfaces and located in said terminal for reducing the'friction between the carrier and the terminal.
5. In an apparatus of the character described, a terminal, a recessin said terminal, and antifriction-rollers located in said recess for reducing the friction between the carrier and the terminal.
6. In an apparatus of the character described, a terminal, recesses in the bottom and sides of said terminal, and antifrictionrollers located in said recesses for reducing the friction between the carrier and the terminal.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 7th day of December, A. D. 1900.
OTTO s. PIKE.
Witnesses:
A. L. Mnssnn, J. L. Hnan.
