TYPOGRAPHICAL OR SLUG CASTING MACHINE.

Application filed May 3, 1915 Serial'No. 25,510.

To all whom it may concern: 7

Be it known that I, JOHN -W. GRAHAM, a citizen of the United States, residing at Hinton, in the county of Summers and State of West Virginia, have invented certain new and useful Improvements in Typographical or Slug Casting Machines, of which the following is a specification.

' My invention relates to typographical or slug casting machines, such as linotypes of the original construction; wherein, circulating matrices are released from a magazine in the order in which their characters areto appear in print, and then assembled in line together with expanding spacers; the composed line brought in contact with the face of a mold; the mold filled with molten metal to form a line of type or slug againstthe matrices, which produce the type characters thereon, and the matrices thereafter returned to the magazine from which they were originally drawn. a

More particularly it relates to that class of machines having a series of magazines,-

any one of'which can be shifted into operative position, and wherein; the magazines are individually removable and exchange able, and, to that end are mounted in a basket or rack support; and wherein, magazine is provided with an individual escapement mechanism consisting of verges and a slotted bar in which the verges are housed and such escapementmechanism is made fast to the magazine.

In the drawings I have shown the invention as applied to linotype machines, but obviously, it may be applied to other machines, such as typesetters, and typecasters,

and many changes and variations may be made therein, without departing from the spirit of the invention. or the principle thereof. Generally speaking I desire to be under stood thatI do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings, Figure 1 1s a side view of a portion of a linotype machlne having my invention applied thereto. Flg. 2 is a frontal and side 'elevation'view of the cog gear and worm gear A Fig. 3 is'a view of the rollers, cogs andsprocket, that are used in the power raising and loweringdevice. Fig. 4 is a back view of the supporting frame or Specification of Letters Patent.

nism for raising and lowering the basket or rack. Fig. 5 is a side view of a section of" rack or basket showing the escapement mechanism. Fig. 6is. a side view of the key board mechanism. Fig. 7 is a view of a magazine looking at the bottom, showing the bar to house they verges and also the strengthemng bars. Fig. 8 is a perspective view of a section of a magazine resting on its angle iron support and showingthe dog, which holds the magazine'in place. is a rear viewof a basket.

Referring to Fig. l 3 A represents aside view of the main-arm or frame which supports the basket or rack. V a circle, and the basket or rack which travels on this arm, travels with a circular motion. The basket, at the front and rear endsfthe arm A, and the guide plates B are 7 all formed in the arcs of I circles, such cir-. cles havlng a common center; thus the motion of the basket is the same as if it were sufficiently forward to be a common center Fig. 9 y,

This arm is formed in the arc of for. all of these circles, but, by suspending the basket to the arm A, we accomplish the desired result without putting any of the mechanism in the way of the operator. It is also apparent to those skilled in the art, that the front and rear ends of the magazines come into operative position at the same time. i

A represents an arm attached to the main arm A, at each side and extending back to support the distributing mechanism, this arm is offset at its point of connection with the arm'A, toallow the piece B to pass behind it.

i A represents a cog gear immediately be hind the worm gear wheel, A (SeeFig. 2.) The gear Wheel A .carries thepiece B 7 A represents a, worm gear wheel intermeshing with the worm} thread on the shaft A i A represents a shaft having at itsv uppermost end a-worm thread, and at its lower end a bevel gear.

A represents a brace to strengthen the main arm A. There are two of these braces, one at each side ofthe forked arm A.

B represents the basket or rack, in which the magazines are housed.

B represents the 1ron straps which pass up the sides of the basket at its ends, and

to which the individual baskets are made fast; these strapsalso rub on the inside of the arms A, and the braces A to guide the travel of the basket.

B represents a strap which travels on the cog gear A and is bolted to the guide bar B B represents the guide bars which are securely affixed to the basket and travel on the main arm A. These guide bars B? are bored out near their ends, and have housed in these sockets, the rollers B B represents rollers set in guide bars, as mentioned above.

B represents an angle iron, one side of which is affixed securely to the straps B at both ends of the basket, and to the guide bars B near the center of the basket; the other angle of this angle iron projectsinto the inside of the basket, at right angles, thus forming the support for the magazines. These angle irons on the inside of the basket work in pairs, one on each side, and are lined on their bottom, full length, thus giving the basket theappearance of a box containing a series of shelves, all converging toward their frontal'point, at the same degree. The object of this lining is to support the magazine when it is pulled back, to be taken out. The magazine being narrower at its frontal end than at its rear end, would drop through at the back, but for this lining. This lining is shown by the line B, in Figs. 8 and 9.

13 represents a dog fitted on the inside of the angle irons B, near the lower, or escapement end of the basket. Its function is to hold the magazine in place. Its construction is suchas to hold the magazine from slipping endwise in the basket and it also holds the magazine down in place.

(See Fig. 8.)

Fig. 2 shows front and side elevation views of the cog gear A and. its connected worm gear wheel A".

F ig.3 shows the rollers,gears and sprocket of the power raising mechanism, with the casting Z removed.

I) represents a roller set stationary below the belt E. Its function is to hold the belt E up in place when the rollers F or G are thrown against the belt E, to operate the power raising or lowering device;

' E represents the belt from which power is generated to operate the power raising and lowering device.

F represents the rubber covered roller of sufficient width to cover the width of the belt E and having behind, and. made fast to it, the cog gear F G and G are exact duplicates of F and F I represents a cog gear, made fast to the sprocket J and of a width the same as F and G1.

J represents the sprocket mentioned above.

Z represents the casting which houses the rollers, gears and sprocket used in the power raising device. It is pivoted on the pin Z which is set securely in the frame of the machine. It is connected at its uppermost end to the strap L which in turn is connected to the lever L. The rollers F and G with their connected cog gears F and G are housed on pins made fast to the casting Z, while the sprocket J and its attached gear wheel I are housed on the pin Z The gear wheel G is intermeshed with the gear wheel F and the gear wheel F also intermeshcs with the gear I, but the gear G does not intermesh with the gear I.

In operating the power mechanism, when the lever L is moved inward sufliciently it rocks the casting Z on the pivot Z and forces the roller G against the moving belt E, which belt E operates the roller G and its connected gear wheel G G is intermeshed with F and thus operates it. F is intermeshed with the gear I, made fast to the sprocket J, and thus the sprocket J is operated. The sprocket J operates the shaft K by the sprocket chain M and the sprocket K, on the shaftK The shaft K operates the screw shafts A by means of intermeshed bevel gears and the shafts A operate the worm gear wheels A and their attached cog gears A, thus operating the basket upward or downward by means of the piece B To reverse this motion the hand lever L, is moved outward sufiiciently to throw the roller F against the belt E and this operates the roller F and its attached gear F F operates the gear I being intermeshed with it and I being fast to the sprocket J operates it, and the power is transmitted as above. Fig. 4 represents a back view of the forked arm A. This view shows the shaft K with its sprocket and bevel gears and the screw shafts A attached to the arm A.

Fig. 5 is a side view of a section of a basket with a section of the strap B cut away; also a. section of angle iron magazine support B cut away; also section of theside of the magazine cut away to show the matrices X in place, held by the verge V; also shows the reinforcing bar slotted to receive the spring P, and also shows trip finger Q, connected to the key rod Q Fig. 6 shows a side view of the key board mechanism.

. represents a key.

Q shows key bar.

Q shows pin on which key bar is pivoted.

Q shows rod to trip the dog R.

B shows leg of the dog R.

B shows rod housing the cam R R shows rubber covered rollers.

R shows spring to hold key rod down.

In operation, when the key Q is pressed it raises the rod Q which moves the dog It and allows the leg R to pass into the slot rod R and not resting on it as in my machine. When the key Q? is pressed it raises the rod QF, in turn operating the dog R, allowing the rod R to drop, but the key rod Q does not drop, but being suspended above the rod R it remains stationary.

When the rod R drops, the cam R comes in contact with the movingroller R and when the cam rolls over to its highest point it raises the rod R sufficiently to raise the key rod Q and the key rod comes in contact with the verge V and trips it, allowing the matrix to escape. In my machine as soon as the key is touched the key rod drops and trips the verge, allowing escapement of the matrix and as the mechanism is moving to restore the rod Q to its place, the operator may betouching another key'and no time is lost. Operators listen at all times to hear the matrices drop, so by the old method the operator has to wait until the operation of keyboard mechanism is complete, before he hears the matrix drop, while in my machine the matrix drops almost instantaneously and the operator can operate another key while the mechanism is readjusting itself. This improvement greatly increases the speed of the machine.

Fig. 7 shows bottom view of a magazine showing strengthening bars W extended out at their ends to act as stop, workin in conjunction with the dog 13, (see Fig. 8

Fig. 8 shows a perspective view of a section of magazine, showing angle iron suports cut away to show the extended end of the strengthening bar W and also the dog 13, dotted in.

Fig. 9 shows a back view of the basket, showing the sheet iron lining.
