Specification of LettersPatent.
Patented Jul 21, 1908.
Application filed January 28, 1907. Serial No. 354,412.
To all whom it may concern:
Be itknown that L'ALBERT W. PEansALL, of Lowell, 'in the county of Middlesex and State of Massachusetts, have invented cer- 5 tain new and useful Improvements in Pneumatic-Despatch-Tube Apparatus, of, which the following is a s ecification.
1 My invention re ates to improvements in terminals for pneumatic des atch tube appa- 'ratus, and is particularly a apted for use in that type of ressure system shown and described in S. Letters Patent #551,602
issued to me Dec. 17, 1895, assignor to the Meteor Despatch Compan The object of this invention is to provide a valve which will seat permanently by the action of the pressure wlthin the system preventingany escape of said pressure and which valve is adapted to be operated by a carrier to open inwardly against the ressure within the system to permit the disc arge of said carrier;
In the accompanying drawings which illustrate a construction. embodying my inventien, Figure 1 is a vertical sectional view of the terminal showing the valve held closed by the pressure within the system. Fig. 2 is a vertical sectionalview of Fig. 1 showing the valve opened by a carrier about to dischar e.
Li e letters of reference refer to like parts throughout the several views. A represents a tube connected with the delivery terminal B for the transmission of 3'5 carriers to said terminal, and O is a transmis- I sion'tube connecting with said terminal for the return of carriers. D is a valve controlling the delivery opening E in said terminal B which valve is pivoted at F and ada ted to "4 0 0 en inwardly. vThis valve is normal y held 0 osed as shown in Fig. 1 by the ressure withirrthe-system, which pressure is ormant. when there are no carrierslgeing transmitted.
A yoke G on the inner side of the valve car ries apin H which is mounted within a slot J in one end of a cam lever K, the opposite end of said cam lever being pivoted to the inner artition of the terminal at L, the whole orming a togglejoint.
M is a buffer secured inside of the delivery o 'em'ng E by screws N-and adapted to receive t e impact of the valve Dwhen openedby a carrier. 0 is a spring'adapted 'to assist in the closing of said valve.
'dischar e through the openin E.
- valve -D upon the opening of the same by any transit through the tube A enters the terminal B, the front buffer of said carrier en agng the cam lever K, the pressure behind forc-' mg saidcarrier to o erate upon and move said cam lever K bac ward from the position shown in Fig, 1 to that shown in Fig. 2, and
7 through the pin H operating in the slot-J opening the valve against the pressure within the terminal and permitting the carrier to After the carrier as passed the valve the pressure within the terminal acting in (3011]11110tl01l with the,s ring 0 closes the valve D. The {buffer M a sorbs any sudden impact of the I carrier. The direction of the air currents during the transmission of the carrier isindicated by arrows (Fi .2).
Having thus descri ed the natureof 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 a terminal for pneumatic despatch tubeapparatus, a valve controlling the delivcry openin .of said terminal and adapted to be norma y held closed by' the pressure within said terminal, and means operated by a carrier in transit in said terminal for opening said valve inwardly against said pressure to permit the'deliver of said carrier.
g 2. In a' terminal or pneumatic despatch tube apparatus, a valve controllingthe delivery opening of said terminal and adapted to open inwardly and normally held closed by the pressure within said terminal, and pivoted means operated by a carrier in transit in said terminal for opening said valve to permit the dischar e of said carrier.-
3'. In a terminal for pneumatic despatch tube apparatus, a swinging valve controlling the delivery opening of said terminal and adapted to open inwardly and normally held closed by the pressure within said terminal,
and a cam lever adapted to be operated by a carrier in transit within said terminal for opening said valve against said pressure to permit the discharge of said carrier.
, 4. In a terminal for pneumatic despatch tube apparatus,'a valve controlling the delivery opening and adapted to open inwardly of said-terminal and normally held closed by thefpressure in the terminalgreater than the exterior atmospheric pressure, and mechanism arranged to be engaged and actuated by 11c m mi the carrier arriving in said terminal and cooperating with and adapted to open said valve to permit the delivery of said carrier.
5. Ina terminal for pneumatic despatch tube apparatus, a swinging valve controlling the delivery opening of said terminal and adapted to open inwardly and normally held closed. by the pressure within said terminal, and a cam lever adapted to be operated by a carrier in transit within said terminal to open said valve against said pressure to permit the discharge of said carrier and provided with a slot in which one end of said valve is pivr oted-the other end being pivoted on the terminal;
In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses, this 25th day of January A. D. 1907. v a
