PNEUMATIQ-TUBE SYSTEM.

ec oes,

T all whom it may concern: a

Be it known that I, BIRNEY G. BATCHEL- LER, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Pneumatic-Tube Systems, of which the following is atrue and exact description, reference beinghad to the accompanying drawings, which form a part thereof.

My invention relates to pneumatic tube systems of the kind in which carriers issue from the tube at an intermediate station and are either held there or transmitted to a second tube for transmission to a'further station.

' The object of my invention is to provide means at such intermediate station by which the carriers are either automatically delivered to the outgoing tube or shunted off at the intermediate station in accordance with selective devices on (he carriers, and in connection therewith to provide means by which the impetus of the incoming carriers is checked before they come in contact with -the selective mechanism and switch and before they are injected into the outgoing tube.

The nature of my improvements will be best understood as described in connectio with the drawings in which Figure 1, is a side elevation of my intermediate station appliances in what I be lieve to be their best and most effective forms. Fig. 52 is a plan view of the same mecl'ianism. Fig. 3, an end view. Fig. 4,

a. view indicating the same general construction shown in Fig. 1, but drawn on a smaller scale so as to show additional features of the system. Fig. 5, is a plan view on an en- 40 larged scale of the selective and switch mechanism. Fig. 6, a side elevation of the same devices. Fig. 7, a detailed sectional view on the line 7 7 of Fig. 8. section on the line 8-8, of Fig. 7. Fig. 9, .an enlarged detail of a partial mechanism shown in Fig. 5. Fig. .10, a cross seotional view'on the line-10 1O of Fig. 9, with the carrier shownin place. Fig. 11, is a side elevation of a modified intermediate station appliance also embodying my invention, and Fig. 12, is a side elevation of still another modification of the intermediate station appliances.

A, indicates the incoming tube, near the Specification of Letters Patent.

Fig. 8, a cross-' end of which is situated a gate A by which the passage of air can be cut off when desired and which incoming tube, as shown in Fig. 1, has attached to it lateral pipe A communicating with the tube through ports A, and having an open elbow A fa gate A, being provided so that the pipe A which is connected with the suction end of a compressor can either draw its supply entirely from the tube A or from the open elbow A or partly through one opening and partly through the other in accordance with the adjustment of the gate A. This appliance Patented June 21, 1910. Application filed May 1, 1905. Serial No. 258,291.

is similar to that described in my former patent of September 12th, 1899, Number 632,690.

Still referring to the main construction of Figs. 1 and 2 etc., B, B, are belt wheels arranged above and in front of the mouth of the tube A, and B, B, simliarbelt wheels arranged above and below the mouth of the tube. B indicates a belt tightener for the upper belt wheels consisting of a pulley fastened on a rock lever B which is adjusted by means of a screw 13*, a similar belt tightener 13*", for the lower belt is fastened on a rock lever .B, and adjusted by a screw B C, is the upper and G, the lower belt. I is a motor driving a shaft D, which as shown is provided with a belt wheel D which through a belt D drives a pulley D*, on a shaft D saidshaft having a worm D, which drives a worm wheel D, attached to the shaft of one of the pulleys B. The shaft B, has also attached to it the worm D which engages and drives the worm wheel D attached to the shaft of one of the pul- F Y I i I I leys D E. is a frame 01 guideway, preferably grooved, and which supports in its groove the upper side of the belt C. E, is a pressure bar on'the under face of which runs the lower face of the belt C. This bar E, is connected with a longitudinal. frame member F, by parallel mot-ion levers G G and is provided witlrlugs E E which support set screws E acting against the links G G, as shown and by which the bar E, is prevented from moving downward beyond a determined point. The bar F, is provided with a laterally extending lug' F supporting a spindle blocK F, through which passes a screw G, to which is attached the tension spring G, connected with the bar E, a threaded wheel G being provided to adjust the tension. Another lateral lug F of the bar F, supports a threaded swivel block F inwhich works a screw 11, which adjusts the tension of a compression spring H, the other end of which rests against the bar E. By ad usting thesesprings any desired pressure of has also a laterally extending flange I servmg as a support for one end of the pivot pin, indicated at I", and near its right hand'end it is provided witha buifer indicated at I -The horizontal flange I, of the plate I, also supports the frame I in which are secured the electromagnet and latching devices to be described, the walls of this frame being cut away as shown at I, Fig. 10, to permit of the. free motion of the switch bar. The plate is also, as shown, formed with slots 1 best shown in Fi 6, to give passage to the selective fingers f, J, which are secured on slotted heads-J J turning on the pin I, the heads having non-conducting pads J secured on their faces andjoperating in connection with spring terminals J J connected with the electric circuit wires J J being a battery and the wires connecting with the electromagnet indicated at M*. J J indicate springs which normally hold the selective fingers J, J, in the position indic'ated in dotted lines in Fig. 5. K, is a switch bar or finger pivoted on the pin I, and normally held in position in which it projects over the belt C, as shown in Fig. 5, by a spring K. L, see Fig. 10, is a pivot pin on which is pivotally secured the 1001;- mg lever L, a spring M being attached to this lever to hold it normally in the position shown .in Fig. 10, and prevents the movement of the switch bar K, out of the path of the carriers. rA lever arm L attached to the locking lever is adapted to engage with the hooked end M of a lever M M, pivoted at M, and the end M, of which lies in position .to be struck and pressed in by the switch as it moves inward under the pressure of a carrierf. L and L, are stop blocks for limitingith'e motion of the locking lever L, and M, is an electromagneta rranged when enrgized'to act on the lever L, drawing it back against the stop L so 'as to give freedom to the switch to move inward. N, see Figs. 2 and 3, is the local delivery platform, at the end of whichlis-placcd jabuffer N. In line with- %1e 11 pergsurface of the belt C, is the chute w device 0', shown in section in Fig. 11, having gates 0 and O and a valve 0*, 0perated by the action of the gates and by which air under pressure is admitted to the lock 0, after a carrier has passed the gate 0 The carriers issue from the air lock 0, into outgoing tube 0 which is supplied with compressed air through a lateral connection O. The construction of this air lock device is that of my former patent of May 20th, 1902, Number 700,607, and need not be particularly described.

In tl1e modified construction shown in Fig. 11, the belt mechanism is dispensed with, th'e incoming tube A, opening into a tube section P, having gates P P actuated by cylinders and pistons indicated at P and P lateral openings P, and P, on each side of the gate P, opening through appropriate connections into a pipe section P, which, as shown in Fi 11, communicates with the ipe section a gate P, being provided y which the flow of air-from the tube A, into the pipe P, may be drawn from either of the lateral openings P or P, and a restricted by-pass P being provided so that when the valve is turned to connect the opening P with the pipe P", a restricted quantity of air under pressure will still be communicated to the chamber P to act to force the carrier out of said chamber when the gate P is opened. The finger P is provided for setting in operation the mechanism for restoring the gates to normal position, all of which is the same as that described in my former Patent Number 749,152, and need not here be further described. In other respects the appliances shown in Fig. 11 do not differ materially from those al-' ready described. I

In the construction shown in Fig. 12, the incoming air tube A, opens into the head Q, from which leads the air pipe X, the carriers entering the head passing around the curved surface thereof and coming in contact with the outlet gate Q, which is held on an arm (2,, pivoted at Q and normally held .closed by the springQ. A lever R, is pivoted at R on the arm Q and provided at one end with a finger R, which projects through the gate Q, as shown, the other end of the lever being provided with a notch R3 for purposes to be described, and the-lever i ichleads downward'into an air lock normally lying in position to prevent the retraction of the switch bar K as shown. In this construction T, indicates the outgoing tube and T, the basket for receiving carriers shunted out at the intermediate station. The construction of the head Q, and its connections in Fig. 12, is similar to that described in the patent to Cowley, No. 7 26,030, ofQlst April, 1903.

I have indicated. the carriers by the. letter issues from the tube A, at full speed directly between the belts C, C which are driven in the same direction as that in which the carrier is moving and at the reduced rate of speed with which it is desired the carrier should travel when it comes in contact with the switch or passes to the out-going tube.

he impetus of the incoming carrier is checked by frictional contact with the belts regulated by the residue weight of the triction regulating bar E, which is adjusted by means of the springs H, and G, so that it will exert any desired pressure upon the upper belt andthroughit upon the. carrier. The upper belt is shorter than the lower one and when issuing from between the belts and while still carried forward by the lower belt the iron t'oi'i' the carrier comes in contact with the fingers .J, J", and if provided with .a metallic plate of such size and disposition that it makes contact with both of these fingers, the electric circuit is closed and the magnet M energized with the result that the stop lever L, is drawn backward so as to clear the switch bar K, in which position it is caught and retained by the engagement of the hook M, with the lever arm L The carrier on coming incontact with the switch bar K, presses said switch bar out of its way and passes forward on the carrier belt C, which finally dumps it into the chute 0, from which it falls intb the outgoing tube. The bar K, when pressed inward comes in contact with the lever arin M, pressing it inward and raising the hook arm M, so as to disengage the lever arm L 1 in consequence of which on the return of the switch bar to normal position the stop lever L, at once resumes its normal position beneath the switch bar, as shown in Fig. 10. In case Jthe selective disk U, is omitted or is of such a character as not to contact with both of the fingers J, J, the electric circuit is not closed, consequently the stop lever L, is not withdrawn and the carrier on coming in contact with the switch bar K, is deflected- ,sidewise on to the table M, for local delivery.

In the construction of Fig. 11, the impetus of the incoming carrier is entirely taken up in the air chamber P, in which it comes to rest and from which it is propelled after the gate P, is closed, and the gate P opened by the limited body of air passing into the air look through the restricted passage P.

The energy developed by this body of air is on] y sufiicient'to propel the carrier out of the air lock with such moderate speed as is not objectionable. In other respects the operation of the carrier on leaving the air lock is precisely the same as described in connection with Fig. 1 except that the motion of the carrier through the switching mechanism and through the outgoing tube is produced entire] y by the impetus given it in the air lock no belt being employed.

In the construction of Fig. 12 carriers having recesses U of such form and dimensions that the head of the carrier does not come in contact. with the inwardly projecting finger R of the lever B, impinges directly on the gate Q, puslnng said gate open, the notched end R of the lever R, moving backward without engaging the head S, or in any. way moving the stop finger 3*, consequen ly the carrier on coming in contact with the switch bar K", finds it locked in position and is deflected thereby into the basket T, for local delivery. If however the head of the carrier is not re cessed or the recess is of such a character as not to give clearance to the finger It, the incoming .carricr impinges first upon said finger, pressing it downward and pressing the notched end B, of the lever upward into position to engage with the head S, so that when the gate Q, opens the head 5, is rotated backward and upward, lifting the finger 3*, so that when the carrier im-. pinges on the switch K, it presses said switch backward out of its path and passes t'reely'into the outgoing tube T.

From what has been said it will be seen that my invention is capable of embodiment in many forms and modifications and I wish it to be distinctly understood that save where special features of construction are referred to in the claims and made limiting elements thereof my said claims are not intended to be limited to the specific mechanical devices illustrated- .Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a pneumatictube system, a station having non-continuous delivery and receiving tubes in combination with a switch situated in the path of the carriers issuing from the delivery tube and adapted when locked to direct the carriers to a point of local delivery, and when unlocked to be deflected by the ,carriers to permit the latter to pass to the receiving tube, and'a lock for the carriers combination with a switch situated in the receiving tube, and a lock path of the carriers issuing from the delivery tube and adapted when locked to direct the carriers to a point of local delivery, and when unlocked to be deflected by the carriers topermit the latter to pass to the for the switch adapted to be actuated by selecting devices on the front ends of the carriers.
