Application led March 17, 1910. Serial No. 550,011.

To all whom it may concern:

Be it known that we, RoLLs PERCU-AL LINK and ARTHUR CHARLES MORGAN, subjects of the King of Great -Britain, residing at London, England, have invented new and useful Improvements in Type Casting and Composing Machines, of which the following is a specification.

This invention relates to type casting and composing machines of the kind wherein the matrices, which are presented one at a time to a casting mold by which separate types are cast, are distributed among two or more magazines which are mounted on a rotary or other movable support by which any magazine can, at will, be brought into position to present the matrices therein to the casting mechanism.

According to the present invention the magazines are carried by a frame which on the depression of a key or like device, is successively raised, rotated and lowered by mechanism controlled by the key. Preferably the arrangement is such that successive depressions of the key or the like serve to bring the magazines to the operative position in the order of their arrangement in the frame. y

The mechanism set in operation bythe key or like device for selecting the maga` zines as required, and for controlling the same so that the required magazine is brought to the operative position, may be actuated by a suitable motor or by manual power.

Tn the particular arrangement hereinafter described, each magazine comprises a number of matrix carrying sectors which are separable from their operating means,

and which are bolted to a plate lodged in a hole provided therefor in the said frame. The raising, rotating and lowering of this frame are accomplished by a nut working on a screw-threaded shaft. vThe nut is re'- strained from rotation during its upward movement until it reaches its highest position, whereupon it is released by spring latchesand allowed to rotate with the screwthreaded shaft through one-third of a revolution (when three magazines are provided This moves one magazine outof alinement and another magazine into alinement with the sector operating means. The direction of rotation of the screw-threaded shaft is then reversed so that the nut descends lowering the alined magazine to its operative position.

The screw-threaded shaft is rotated a definite number of times, first in one direction and then in the reverse direction, by a shaft driven through a clutch which is preferably stopped automatically when the rack has made one complete to and fro movement.

In order to unlock the oints coupling t-he sectors to the sector operating means, the nutis provided with a cam surface which acts through levers to impart the necessary rotary movement to the sectors to unlock these joints before the nut commences to raise the frame. The sectors of a magazine which is being lowered into the operative position are likewise turned by a similar cam acting through corresponding levers whereby a proper engagement of the said sectors with the sector operating means is insured.

In many constructions it will be inconvenient to arrange the bayonet or like joints of the several sectors so that they are all unlocked by the same angular travel. The lever with the longesttravel is therefore alone moved directly by the cam, in such a case, and the other lever or levers are moved by a lug or lugs on the first mentioned lever. The ends of these levers may be provided with pivoted clips or grooved rollers for engaging the sectors.

The plates carrying the magazines are locked in the frame above mentioned, by means of a bolt which can'be withdrawn by hand. This bolt operates to unlock the magazine from the frame and, at the same time, if necessary, through the levers abo-ve mentioned, to unlock the sectors from their operating means, so that any magazine can be removed from the frame and another magazine substituted therefor. Vith this arrangement a magazine can be lifted out of the operative position and replaced by another magazine either automatically on the depression of a key, or by hand, as may bev most convenient.

Referring to the accompanying drawingsz-Figure l is a plan of a magazine changing mechanism embodying the present improvements, and Fig. 2 is a side elevation of the same partly in vertical central section. Fig. 3 is an enlarged view of parts shown in Fig. 2 represented in the positions respectively occupied by the same when at rest. F igs. 4 and 5 are views similar to Fig. 3 showing the movable parts in other positions respectively occupied by the same during their operation. Fig. 6 is a plan of parts shown in Fig. 3. Figs. 7 and 8 are detail views illustrating the operation of levers, shown also in Fig'. 6, employed to unlock the sectors. Fig. 9 is a detail plan of a slider employed to move the levers for unlocking the sectors. Fig. 10 is a detail view of a preferred form of driving clutch, shown in cent-ral section, and a detent controlling the operation of this clutch, and Fig. 11 shows parts of Fig. 1() viewed from the left of that figure.

As shown in these drawings each magazine comprises four sectors 2 arranged in pairs in dierent planes, the members of each pair being disposed symmetrically about a center line, when in their positions of rest. These sectors are provided with tubular extensions 3 which are adapted to be connected by bayonet or like joints 4 (Fig. 3), to sector operating means represented as tubular parts or sleeves 5, contained in a cylinder 6, Fig. 2. Each pair of sectors in the same plane are connected one to the other by springs (not shown), in order to hold the joints connecting the sectors to the said tubular parts or sleeves, in their locked positions. The sectors comprised in each magazine are supported by sleeves 7 provided with extensions 8 supporting flanges 9 which are bolted together and to a plate 10. Three magazines thus arranged are mounted in recesses in a frame 11 by means of rims 12 on the plates 10 resting on the said frame which is actuated, as hereinafter described, to move the magazine so that any one of the same, at will, can be brought int-o position within the cylinder 6 in order that the matrices contained therein may be available for use.

In Figs. 1 and 2, a key 13 is shown which, when depressed, acts through a link 14, bell-crank lever 15 and link 16, to draw down a detent 17 to release a member 18 of a driving clutch. The said member 18 is then moved by a spring 19 into engagement with the other clutch member 20 which is fast on a constantly rotating shaft 21, see Fig. 10. When this clutch is operative, a shaft 22, to which the clutch member 18 is keyed, is driven by the shaft 21. When the shaft 22 has moved through nearly one revolution, a cam 23 on the movable member 18 of the clutch encounters and slides past a fixed pin or roller 24 supported on a suitable part of the frame work of the mechanism. The clutch member 18 is thus moved to its inoperative position against the thrust of the spring 19. As the cam 23 passes the pin or roller 24, the detent 17 rises to lock the clutch in its inoperative position. The

momentum of the shaft is sulicient to cause the cam 23 to over-run the pin or roller 24 so that the shaft continues to rotate until a lug 25 (Fig. 11), on the clutch member 18, is stopped by the said detent thus insuring that the shaft 22 is always brought to rest at the end Qfeach complete revolution and in exactly the same position.

A cam 26 on the shaft 22 is arranged to move a rack bar 27 in one direction and then release this bar Vso that it can be kbrought back to its original position by a spring 28. This rack bar actuates a train of gearing 29 driving a shaft 30carrying a pinion 31 in gear with a toothed wheel 32 keyed to a screw-threaded shaft 33. From this description it will be readily understood that, when the key 13 is depressed, the shaft 33 is first rotated in one direction through a given number of revolutions, depending yon the stroke imparted to the rack bar by the cam 26, and also depending (on the velocity ratio of the toothed gearing 29 and 31, 32. After this the rack bar 27 is released by the cam 26 and is then drawn back by the spring 28. This causes the shaft 33 to rotate in the reverse direction until it is brought back to its original position.

A nut 34 mounted on the screw-threaded shaft 33 is normally restrained from rotating with this shaft by the engagement of grooves 35 formed therein, with ribs 36 proj ecting from fixed parts of the frame. `When the shaft 33 is rotated, the nut is raised and clutch teeth'37 provided on the same, enter between corresponding teeth 38 provided on the underside of the frame 11 (see Fig. 4). Further upward movement of the nut then raises the said frame carrying with it the magazines.

At therupper ends of the ribs 36, spring controlled latches 39 are arranged to form continuations of the ribs 36. Prior tothe release of the rack bar by the cam 26, the grooves 35 pass off from the upper ends of the ribs 36 (see Fig. 5), and press against the latches 39 which yield and allow the nut to rotate with the shaft. By the engagement of the teeth 37, 38, the frame 11 is also carried along by the nut in this rotary movement which ceases when the frame has moved through one-third of a revolution, or a little more, the cam 26 and the upper ends of the ribs being properly adjusted to give this result. Each groove 35 in this movement is advanced from one latch 39 to the next, respectively.

The shaft 33 immediately after the release of the bar 27 by the cam 26, is rotated in a reverse direction by the action of the spring 28. If the grooves in the nut are not already in engagement with the latches the nut is turned back with the shaft until stopped by the said latches which are arranged to permit the nut to rotate in one -ribs 36 descends and lowers the frame 11 to its original position.

By means of this mechanism, on actuating the key 13, any magazine in the cylinder 6 can, in successive stages, be first raised and then moved laterally away from the lat-ter while another magazine can be brought into alinement with the cylinder and then lowered into the required position therein, so that by successive actuations of this key each of the magazines carried by the frame 11, can be brought to the operative position, in t-urn. The frame 11 is provided with a central rod 40 passing through a guide-bar 41 to prevent tilting or other undesired movements of the'said frame, while in motion, or while at rest in its raised position. When the frame is lowered a socket or recess 38a provided centrally between the teeth 38 engages on a cylindrical part of the shaft 33 thus affording a firm support to the frame in this position also. Y v

As above mentioned, in the construction shown, the sectors comprised in a magazine are connected to the sector operating means by bayonet joints 4. It is therefore necessary, before a magazine lodged in the cylinder 6 can be lifted out of the same, to unlock these joints. For this purpose, as shown in Figs. 3 to 8, each magazine comprises one pair of levers 42, 42, provided to unlock the joints of the upper sectors, and a second pair of 4levers 43, 43 provided to unlock the oints of the lower pair of sectors. These levers turn about pivot pins 44 carried on the plate 10. In order to actuate these levers, cams 45vprovided on the nut 34, are arranged to act on a slider 46, mounted in a guideway 47 provided in a fixed part of the frame. Each cam is brought, in turn, to its operative position opposite the said slider by the rotary advancing movement of the nut. The slider 46 is advanced4 toward the cam by a spring 48 supported by a fixed part 49 of the frame.

As soon as the nut 34 commences to rise, the slider is moved back by the cam 45 which is opposite thereto, and causes the levers 42 toturn the upper pair of sectors against the force of their controlling springs from the position of rest shown in Fig. 6 .to the position shown in Fig. 7. Lugs 50 provided on these levers then engage lugs 51 on the levers 43 so that thereafter both pairs of levers move together until they occupy the positions shown in Fig. 8. This position of the levers corresponds to the position of the nut as shown in Fig. 4. In this position the sect-ors are unlocked from the sector operating means, the teeth 37. have entered between the teeth 38 and, as the nut continues to ascend, the frame 11 is raised carrying with it the magazines. During the further upward movement of the nut, the slider 46, under the action of the spring 48, moves back toward the right, traveling along the cam 45 until a stop piece 52 on the said slider engages the guideway 47. At the same time the spring controlled sectors press back the levers 42, 43 to their original positions after the interengaging parts of the joints have been moved clear away from one another.

After the frame has rotated to bring a fresh magazine into alinement with the cylinder 6, the nut again descends, as hereinabove described, and the slider is moved to open the sectors so that the parts of the joints formed thereon can engage the corresponding parts on the sector operating sleeves. When the magazine has been lowered into the cylinder 6 and the members of the joints 4 are opposite each other, the frame 11 ceases to descend but the cam con-- tinues to move down until the slider 46 has been brought to the position shown in Fig. 3, by its spring 48, permitting the sectors to come to their normal positions of rest, as shown in Fig. 6. The arrangement of the lugs 50 and 5l is not essential as both pairs of levers may obviously be moved directly by the slider and, vif necessary, these levers may be made of dierent lengths to give the desired angular travel to the sectors.

The ends of the levers acted upon by the slider are provided with rollers and the other ends of these levers are provided with suitable forks 54 to engage the edges of the sectors. These forks, as shown in the drawings are pivoted to the levers. However, if desired, grooved rollers may be used in place thereof.

To provide means whereby a magazine can be withdrawn from the frame 11 by hand and another magazine substituted therefor without requiring the nut 33 and cooperating parts to be actuated, even when the magazine to be withdrawn is in its operative position in the cylinder 6, a sliding pin 55 is arranged in a slot 56 in the plate 10. This pin is formed with a part, which can be conveniently grasped by the hand of an operator, extending out of the slot, and the said pin carries a plate 57 which is so arranged that, when the pin is moved toward the left, Fig. 3*, the levers 42, 43 are operated to unlock the sector joints 4.

A bolt 58 is employed to enter a hole 59 in the frame 11 and lock the magazine to the said frame when the rim 12 of the plate 10 is properly seated thereon. This bolt project-s from the plate 57 so that when the latter is moved, for example to unlock the levers 42, 43 as above described, the bolt is withdrawn and the magazine can be lifted from the frame, as required.
