CARRIER FOR PNEUMATIC TRANSIT-TUBES.

SPECIFICATION forming part of Letters Patent No. 657,079, dated September 4, 1900.

Application filed November 8, 1898. Serial No. 695,832. (No model.)

3e it known that I, BIRNEY C. BATCHELLER, 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 Car` means for securinga cushion on the front end of the carrier which will not involve the use of bolts or other detachable securing devices passing through the carrier and which pref` erably will permit both the ready attachment and detachment of the cushion.

A further object is to provide for the convenient and secure attachment and ready detachment of selectin g-disks'to the front of the cushion. I

A further object is to so hinge the lid to the carrier-cylinder as to permit of its seating itself on the end of the cylinder by a substantially-straight inward movement, an object secured by connecting the lid and cylinder by what maybe aptly termed a chain hinge, having two or more links intervening between the connected parts and preferably of such a character as will permit of the lid being moved freely away from the open end of thecylinder when desired. In connection with the chain-hinge connection I prefer to employ a substantially-round gasket seated on a conical flange of the lid and acting when the lid is closed against a conical seat.

A further object is to provide means which will lock the bolts in their inward or non-operative position at all times except when the lid is properly seated on the carriercylinder.

A further object is to provide a bolt-actu ating device movable from an operative to a non-operative position and in connectionV therewith a locking device which will prevent a movement of the bolts to unlock them except when the said actuating device is moved to operative position.

A further object is to construct the said lock-actuating device, preferably a lever, in such a Way that when in operative position it will project beyond the sides of the cylinder to such an extent that it cannot be brought to operative position and at the same time inserted with the carrier into the pneumatic tube.

A further object is to provide a locking device which will prevent the movement of the locleactuating device or lever from operative to non-operative position at any other time or position than that corresponding to the locking position ofthe bolts.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated as embodied in what I believe to be their best and most practicable forms and in which*- Figure 1 is a longitudinal central section of a carrier having my improved features of construction, Fig. 2 being a fragmentary view of a portion of the lid and the lock-actuated lever, showing the said lever in operative position. Fig. 3 is an elevation of the outer face of the lid. Fig. 4 is an elevation of the inner face of the lid, the view being taken on the section-line 4 4 of Fig. 1. Fig. 5 is a separate view showing a portion of the locking devices used in connection with the lock-actuating lever. Figs. 6 and 7 are plan views of the plates through which the lockactuating lever is actuated, with the lock-actuating mechanism on the inside of the lid. Fig. 8 is a cross-section through the lid and lid end of the carrier-cylinder, taken on the section-line 8 8 of Figs. 3 and 4. Fig. 9 is a section taken on the line 9 9 of Fig. 4. Fig. 10 is a detached view of the conical lidseat, the section being the same as that of Fig. 8. Fig. 11 in a plan View of a bolt-guiding plate used on the inside of the lid. Fig. 12 is a detached view of the gasket'used in connection with the lid and lid-seat, the gasket being shown in section. Fig. 13 is a sectional'view of the head of the carrier and its attachments, taken at right angles to the section of Fig. 1 or on the section-line 13 13 of Fig. 1. Fig. 14 is a front vieW of the head of the carrier and the mechanism attached thereto. Fig. 15 is A a fragmentary plan view of a locking-flange secured on the head of the carrier, Fig. ll

being a similar edge view of the same device and Fig. 155 a view illustrating a detail of its construction. Fig. 17 is a fragmentary plan View of a correspondinglocking-flange secured on the cushion, Fig. 18 being an edge view of the same device. Fig. 19 is a plan View of the spring-holding plate E5, used in connection with the selecting-plate-holding mechanism, Fig. 2O being a cross-section on section-line 20 2O of Fig. 19 and Fig. 21 a cross-section on the section-line 21 21 of Fig. 19. the selecting-plate-locking stud, and Fig. 23 is a side view of a key adapted for operating the locking-stud. v A indicates the cylindrical body of the carrier, and A' its front end or head, this head.

and the body of the carrier being preferably made integral, as shown, as the best way of providing against any leakage through they front end of the carrier.

A2 indicates the open or rear end of the and preferably, as shown, inwardly-extend-y ing flange D', which, like the flange C', is cut away at one point, (indicated at D2.) The lring D is secured to the inner face of the cushion by means of rivets, as indicated at e, and by pressing one edge, as d2, of the flange D under the edge c2 of the flange C and then turning the cushion the entire flange D' can be turned under the flange C', and the cushion thus securely locked in place on the head of the cylinder. To facilitate the interlocking of the two flanges, it is convenient that the edge c2 be turned up slightly, as indicated in Fig. 155, or of course the corresponding edge d? of the other ring might be turned down to the same extent, and to facilitate the disengagement of the two rings it is convenient that the edge of the flange C' opposite to the edge c2 should be turned down, as indicated also in Fig. 155. The cushion is formed by sewing two pieces of strong material, preferably leather, together, the parts being indicated at E and E' and the sewed peripheral edges at e'. The filling of the cushion (indicated at I) should be of hair or some other elastic and compressible material, and it is desirable that the front of the cushion should be for a certain extent, at least, flat. I reinforce the central part of the leather disk E' with a metal plate E5, secured to it by rivets e4. The center of the plate E3 is formed withja circular perforation, as indicated at e3, a similar perforation being formed through the Fig. 22 is a detached sectional view of leather -disk E', and to the center of the plate E3 is secured, as by means of rivets e5, a plate E5, having an outwardly-projecting boss E5, which extends through the central perforation in the plate and leather disk. The boss E6 is internally threaded, as shown, and to the rear face of the plate E5 is secured a plate E7, having a transverse dish-shaped groove E8 formed in it, as best shown in Figs. 19, 20, and 21. Lying in and supported on the shallow outer face of this groove is a flat spring, indicated at F, (see Figs. 13 and 14,) the spring normally resting fiat against the inner face of the plate E5.

G is a threaded stud adapted to screw into the boss E6, the stud being formed lwith an outwardly-extending ange G', an angular central perforation G2, and a straight slot G3 of width sufiicient to give passage to the spring F, formed across its inner end.

H is a selecting-plate of the kind used for making electrical contacts with selecting devices governing the receipt or transit of the carrier, the course of the carrier depending on the diameter of the particular selectingplate with which it isprovided. Such plates are preferably formed, as shown, with their centers dished and perforated, as indicated at H.

J, Fig. 23, isla key having an angular portion J', adapted to engage with the angular perforation Gg of the stud and of a length exceeding somewhat the length of the stud.

When it is desired to remove the selectingplate H, the angular portion J' of the key J is inserted in the lperforation of the stud and pressed against the spring F until its center is pressed into the dished slot E8 to a sufficient degree to clear the slot G3 in the stud. The key is then rotated so as to unscrew the stud and permit the removal of the selectingplate. To secure a new selecting-plate in place, it is placed on the front of the cushion and the stud passed through its center and screwed into the threaded boss E6, the key pressing the spring away and permitting the flange G' of the stud to be firmly screwed down against the selecting-plate, the removal of the key permitting the spring F to move up into the slot G3 of the stud and effectually lock it in place.

Referring next to the open end of the carrier, K is a conical lid-seat firmly secured, as by rivets, to the inside of the open end of the cylinder.

K' K', &c., (see Figs. 8 and 10,) are boltholes formed on the inner edge of the seat.

L isa hinge-block firmly secured to the inside of the casing, as shown, (see Fig. 8,)and to which is attached the link L' of a chain hinge L' L2 L5'L4, the link or plate L4 being attached to the inside of the lid and the links L2 and L'5 intervening between the lid and cylinder. The device which I have called a chain hinge shares the peculiarities of a chain in that it vconsists of a number of links free to turn on each other in one direction ICO IIO

and also those of a hinge in that it permits angular movement of the lid only in one direction. In the plane at right angles to the hinge-joints the lid is movable as freely as though secured by a rope; but it is without freedom to move in other directions and therefore always occupies the same position on the conical seat when closed.

M is the lid, which is formed with an outwardly-extending conical flange M', preferably having a peripheral outwardly-extending ange M2, which when the lid is seated rests against the end A2 of the cylinder. The center of the lid M is, as shown, formed with a circular perforation, (indicated at m.)

M3 is an annular ring secured around the inner edge of the lid M, preferably having its outer end projecting somewhat beyond it, as shown, the ring being bent so as to form boltguiding recesses M4. (See Figs. l and 4.)

M5 (see Figs. l, S, and 1l) is a plate having a central perforation corresponding to the perforation m in the lid, which plate is secured to the center of the lid and is formed with bolt-guide recesses M6, radially corresponding with the guides M4, formed in the ring M2.

N is a circular plate or disk fitting in the perforation m and extending through the perforation in the plate M5. To the outer face of this disk is firmly secured, as by rivets, a plate N', (shown in detail in Fig. 6,) one end of which, N2, is recessed, as indicated at N 4, flanges N3 N2 on each side of the recess being thrust upward from the face of the lid, as indicated in Figs. l, 6, and S. To the end N2 of the plate N' is iirmly secured the hinge-eye plate N5. (Shown in detail in Fig. 7.)

N6 (see Figs. l, 2, 3, 5, and 8) is a segmetal plate rmly secured to the lid, as shown, and having a langeNexiending inwardly toward the center of thelid and outwardly from the plane of the lid, said flange being recessed at N2, (see Fig. 5,) so that the end N8 of the flange N7 will lie to one side ofthe hinge-eye opening in the plate N5 when it is turned to the position shown in Fig. 3.

O is a pivot or hinge pin secured in the hingeeye of the plate N5 and which passes through the head O' of the lock-operating lever O2,

the parts being arranged so that in one posi-` tion the head O' of the lever lies in the recess 'N2 of the iiange NT and in close registry with the end NS of this flange. The head O of the lever is formed with a recess o', which when the lever is turned to the position indicated in Fig. 2 enables the head O' to clear the iiange N7, permitting the recess and the parts attached thereto to be turned toward the left, as shown in Fig. 3, such movement of the lever, however, causing the recess o' to so interlock with the flange N7 that the lever cannot be moved backward until the parts are again turned to the position shown in Fig. 3. It will be seen that when the lever O2 is turned outward or into operative position its free end 02 projects to a considerable distance beyond the outer face of the cylinder, a construction which will etfectually prevent the insertion of the carrier into a transmissiontube while the lever is in its operative position and which will also prevent the lever from moving to an operative position while the carrier is within the tube. In its nonoperative position, that shown in Figs. 1 and 3, the lever is folded down against the outside of the lid, and its free end 02 is engaged by a catch O2, held in operative position by means of a spring O4, as shown in Figs. l and Secured to the inner face of the disk N is a plate P, which rotates with the disk N and by means of which motion is given to the locking-bolts. As shown and as most conveniently constructed, the plate P has formed in it cam-slots P', corresponding in number to the bolts used in connection with the lid, and preferablyitis also formed with notches (indicated at P2) in its periphery, the purposeof which Will be hereinafter described.

Q Q, dac., are bolts the outer ends of which pass through the guideways M4, while their inner ends are preferably made forked, as indicated at Q', Fig. l, so as to pass on each side of the plate P, the inner fork extending into one of the guideways MG of the plate Q2 is a pin which passes through the forked ends Q' of each bolt and through one of the cam-grooves P' of the plate P. It will readily be seen howv in view of the construction above described the movements of the lever O2 control the movementof the bolts.

R R are bolts fulcrumed on pins M7 M7, se-

cured on the inner face of the lid and havingA rearwardly-extending lever-arms R', which are pivotally connected withbars or rods R2, the outer ends of which extend through the guideways M4, formed in the ring M3.

R3 R3 indicate pins extending out from the bars R2, and R4 R4 are springs which press against the pins R2, tending to throw the rods R2 Outward and the bolts R inward. The length of the rods R2 is such that they nor'- mally project for some distance beyond the edge of the lid M, and when the pawls R are in registry with the notches P2 the openings R4 cause such pawls to be forced into the notches. This registry of the pawls and notches, however, only occurs when the bolts are fully withdrawn and the notched plate P is in its corresponding position in each position of the bolts and plate, and when the lid is opened the pawls effectually lock the bolt-actuating plate P against a movement in a direction to force the bolts outward. As the lid is placed in position to close the carrier-cylinder the outer projecting ends of the rod R2 come in IOO IIO

contact with the conical seat K, which presses actu atin g-lever to move the plate P and throw i the bolts outward into engaging osition.

D b C p cls While any convenient form of gasket can be used to make a tight joint between the conical liange M of the lid and the conical seat K in the end of the carrier-cylinder, I prefer to use a gasket S, of rubber or like material, having a substantially-circular section, as indicated in Fig. l2. Such gaskets have been long known for use in connection with preserve-j ars and like receptacles, and I adapt my carrier to their edective use by uniting the lid and cylinder by means of what I have referred to as a chain hinge Which permits the lid to be inserted in or on the carrier by a substantially-straight inward push.
