CARRIER FOR PNE UMATlC-DESPATCH APPARATUS.
SPECIFICATION forming part of Letters Patent No. 779,638, dated January 10, 1905.
Application filed April 23, 1904:. Serial No. 204,616.
To all whom Lt may concern:
Be it known that I, CHARLES H. BURTON, of Boston, in the county of Sutfolk and State of Massachusetts, have invented certain new and useful Improvements in Carriers for Pneumatic-Despatch Apparatus, of which the following is a specification.
My invention relates to new and useful improvements in carriers for pneumatic despatch-tube apparatus; and its object is to produce a water-tight cover for the open end of the carriers with improved locking mechanism for said cover.
A further object of my invention is to provide mechanism for locking the cover to the shell of the carrier before the carrier can be inserted into the tube.
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 perspective view in elevation of one head of the carrier with the cover locked in position. Fig. 2 is a similar view to Fig. 1, showing the position of the parts when the cover is either being locked to the carrier or unlocked therefrom. Fig- 3 is a cross-sectional View from one end of the carrier and cover with the operating-lever in full lines. Fig. 4 is a side elevation of one end of the carrier, showing the cover in its open position.
Like letters of reference refer to like parts throughout the several views.
A represents the shell of the carrier, provided near one end with a friction-packing A of ordinary construction, and to the exterior of the shell at one end is secured the plate B by the bolts B. In the eyes in the upper end of this plate B is located a shaft B and on said shaft is loosely mounted the eye B of the plate B", secured by the bolts B to the cover C, (see Fig. 3,) and by this arrangement the cover and shell are pivotally connected. This cover C is provided with an outwardly-extending vertical circular flange C, provided with a transverse rim C which fits over the outer end of the shell A, Fig. 3. Secured in the shaft F, to which is fixed fast the toothed segment-gear G, and secured fast to said gear.
is the lever G, having the handle g; This toothed segment-gear engages with the rack G on the bar G to reciprocate the same in the top of the cover. On one end of said rack-bar G is a bolt G controlled in its movement by the guide Gr fast on the top of the cover C, and said bolt is adapted to move outwardly to engage the holes G G, respectively, in the flange C and shell A of the carrier. In the opposite end of the rack-bar G are located two semicircular recesses J, in which are located the rounded ends K of the bell-crank levers K, pivoted at K to the cover C. The other ends of the bell-crank levers arepivoted at L to the bolts L, controlled in their movements by the guides L secured to the cover C. Located within the cover C is a yielding buffer-head M, secured to the shell of the carrier by bolts M. Over this buffer-head there is adapted to move the lever H on the pin H, located in the top of the bracket H, which is secured by suitable bolts to the cover C. (See Fig. 3.) The opposite end of the lever H is cut away, as shown at H leaving two projecting edges H. (See Fig. 1.) When the cover is locked to the shell of the carrier, as shown in Fig. 1, this lever H is Within the circumference of the shell of the carrier and does not interfere with the insertion of the carrier into the tube; but when the cover is being locked or is unlocked, as shown in Figs. 2 or 3, or when the cover is entirely open, as shown in Fig. 4, this lever H projects beyond the periphery of the cover, and consequently beyond the shell of the carrier, and
the carrier cannot be inserted into the tube for transmission. WVhen the lever G is pushed down to operate the bolts and lock the cover to the shell of the carrier, it takes the position shown in Fig. 1, so that the edges H of the lever do not contact with this lever, and therefore allow the lever H to be moved around into its locked position. (Shown in Fig. 1.) With the lever G in the position shown in Figs. 2 or 3 the lever H cannot be moved inwardly, so as to Withdraw it within the periphery of the cover, as the edges H will contact with the lever Gr, so that this lever H can only be operated to be brought within the periphery of the shell of the carrier when the lever G is down in its locked position. (Shown in Fig. 1.)
With the parts in the position shown in Fig. 4c, the articles having been placed in the carrier, the cover is moved over and closed in the position shown in Fig. 3. The operator then taking hold of the handle 9 moves the lever Gr toward the right, thereby operating the rack-bar G the bolt G and bolts L, which pass through openings G G in the cover and shell of the carrier, respectively. After the lever G has been pressed fully down, Fig. 1, the operator takes hold of the lever H and brings the same round into the position shown in Fig. 1, thereby preventing the lever G from rising and withdrawing the bolts and unlocking the cover from the shell of the carrier. During transmission in the tube thislever H cannot move out sufliciently to allow the lever G to move upwardly to unlock the bolts. When the carrier reaches its destination, the operator taking hold of the lever H moves the same to the position shown in Fig. 3, then taking hold of the handle 9 lifts up the lever G, thereby Withdrawing the bolts and unlocking the cover from the shell of the carrier, when said cover can be raised or opened for the removal of the articles. This operation for the locking and unlocking is repeated for each trip of the carrier through the tube. This construction of the cover, together with the locking mechanism, prevents water which might be in the transmissiontube from entering the carrier.
From the foregoing it is clear that when the lever H extends beyond the periphery of the carrier the carrier cannot be inserted into the tube, and when the locking operation has taken place and the lever H is moved around into the position shown in Fig. 1 the lever G is prevented from moving upward, and consequently the bolts cannot be Withdrawn and the cover is locked to the shell of the carrier until unlocked by the operator at the other end of the line.
I do not limit myself to the arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.
Having thus described 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
