.To al?, whom, it may concern:

Be it known that l, PIHLIP T. DODGE, of Brooklyn, county olA Kings, and State of New York, have invented a new and usefull Improvement in Linotyp eMachines, of which the liollowingis a specification.

My invention has reference to typographie machines in general, but more particularly to linotype-machines of the organization represented in Letters Patent of the United States No. 436,532. This machine employs circulating type-matrices which are selected one at a time and assembled temporarily in line in the proper order, together with justifying-spaces, the composed lines being presented to a mold to form the characters on the edge of a slug cast therein, after which the line is distributed. These matrices are stored in an inclined channeled magazine, 'from which they are released at the lower end one at a time by the action of the escapement devices controlled by linger-keys for delivery successively to the assembling mechanism. After use at the mold the com posed line is lilted to the top ol the machine, disintegrated, and the matrices returned through a distributing mechanism to the upper end of the magazine. Tn the machine as ordinarily constructed the magazine, carrying the escapement devices in its lower end and a channeled throat or entrance-plate at the upper end, was removable in order to permit the substitution of other magazines containing matrices for type characters of different Vfaces or styles. The parts were so constructed and arranged that the magazine could be removed only by passing it and the heavy base-frame secured to its under side backward over an elevated bar in the main irame. As the magazine and contained matrices weigh considerably more than one hundred pounds, the operation was laborious and dangerous and required the united efforts of two men.

The aim of my invention is to so arrange and organize the parts as to permit more easy and speedy removal and replacement of magazines.

To this end it consists mainly in the employment of a hinged frame to support the magazine, the parts being so arranged that this frame and the magazine thereon may be released and turned downward from the operative position to a position which. will permit the easy removal ol the magazine and the substitution oi another, after which the frame and the magazine thereon may be restored to the original position.

`Figure l is a side elevation oil the upper portion of a linotype-machine constructed inaccordance with my invention, Fig. 2 is a rear elevation oi the same.

Referring to the drawings, A represents the rigid main irame, B the inclined channeled magazine, and C the fixed horizontal distributer lying above the upper end of the magazine for the purpose of distributing the matrices thereto in the ordinary manner.

D is the throat or entrance forming a continuation o'l the upper end of the magazine and curved upward into position to receive the matrices falling from the distributor and guide them into the magazine.

E represents one of the escapement devices at the lower end of the magazine to control the delivery of matrices therefrom. There is, as usual, a row or series of these pivoted escapements, one for each channel ol the magazine, each escapement being actuated by a vertically-reciprocating reed or bar F, connected with the linger-key meclb anism, so that when a key is actuated the escapement releases the corresponding matriX.

G is the vertically-channeled face plate or guide, through which the released matrices descend to the composing mechanism below.

In their general construction and operation the above parts are similar to those in the ordinary machine.

The magazine B instead of being continued downward, as usual, to receive and carry the escapements is terminated at the point d, and the escapements are mounted in a Yfixed channeled part l/,iorming a continuation of the magazine. The throat or channeled entrance D, through which the inatrices enter the magazine, instead oi being hinged to and movable with the magazine, as usual, is connected by horizontal pivots d to supporting-arms d', which are secured at their upper ends to a rock-shaft d2, seated in bearings in the main iframe, so as to admit of the throat being swung upward and backward away `from the magazine, as indicated by dotted lines. The magazine B is seated upon and sustained by an underlying ilat trame H, having its forward end sustained in the main frame by lateral journals l the magazine at the point l) it may be conor trunnions h and its upper end sustained by horizontally-movable screws or pins h, seated in the main frame, the arrangement being such that when the supporting-screws 7L are retracted the frame H and the magazine thereon may be turned downward from the operative position to a lower position of rest, as indicated by dotted lines. The downward movement may be limited at any desired point but l prefer to carry the frame down until it has a downward and backward inclination, as shown in Fig. l. The magazine is supported in such position that it may be conveniently grasped and removed and another substituted on the frame H, after which the frame may be swung upward to its original position and again secured by the supporting devices.

The employment of the hinged rising-andfalling frame H is advantageous in that it permits thc employment of a very light magazine which may be readily handled and in that it permits the operator, sustaining a portion only of the weight, to readily carry the magazine downward to a low level, so that it may be conveniently and safely removed by a single person. The magazine may be secured in position on the swinging frame in any suitable manner, but preferably by providing it on the under side with one or more cross-bars h, which may be seated in a corresponding groove in the top of the frame to prevent the magazine from accidentally shifting or changing its position thereon. ln removing the magazine it is only necessary to lift its end slightly from the lowered frame and then withdraw it endwise, as indicated by dotted lines. The throat D and the escapement mechanism remaining immovably in the main frame will serve their purpose with any magazine which may be inserted.

In order to permit the employment of the falling frame H, the main frame must be so constructed as t'o give the frame support in both sides and also support the distributing mechanism and the throat D without interfering with the falling motion of the frame H. This is preferably accomplished by extending from the column of the main frame rising past one side of the magazine an underhanging arm or portion, such as shown in the drawings, adapted to extend over and across the magazine and to extend downward on the outer side of the same.

The distributing mechanism herein shown consists of the usual bar C, toothed on its lower edge to sustain the correspondinglytoothed matrices traveling lengthwise thereof until they arrive over their appropriate channels, and parallel screws adjacent to said bar to engage the' edges of the matrices and carry them along the bar.

It is manifest that instead of terminating tinued, as usual, to support the escapements,

and that in such event the escapements will be removed with the magazine, but the construction shown in the drawings is for many reasons preferable.

The essence of the invention lies in the employment of the hinged falling frame to support the removable magazine and sustain the same in operative relation to the other parts, and it is manifest that the details may be varied at will, provided no change is made in the general mode of action.

ln order to relieve the attendant of the whole or a portion of the weight, l propose to employ a counterbalance of any suitable character in connection with the frame H. l recommend the arrangement represented in the drawings, yconsisting of a strong compression-spring l, encircling a rod t', which is jointed to the under side of frame H at i and arranged to bear at its lower end at i2 on the main frame. As the frame falls the angular relation of the spring-actuated rod to the magazine changes, as indicated in dotted lin es, so that it exerts little or no lifting effect when the frame is fully down. As the frame rises, however, toward the operative position the iniiuence of the spring increases, so that the operator is relieved of the greater part of the weight, or, if desired, of the whole weight.

It will be observed that under my arrangement of parts the magazine and its support- Having described my invention, what l i claim isl. In a linotype-machine, the combination of the following elements: the main frame, an escapement mechanism and a distributing mechanism, both secured therein, an inclined detachable magazine seated between and in operative relation to said mechanisms, a sustaining-frame underlying the magazine and hinged at its lower end to the main frame, and means for sustaining and releasing the rear end of the hinged frame.

2. In a linotype-machine, the main frame provided with fixed escapement and distributing mechanisms and the intermediate magazine in operative relation to said mechanisms, a sustaining-frame for the magazine, hinged to the main frame to swing downward, in combination with the main frame overlying and spanning the magazine, with an unobstructed space under the latter, and movable connections between the main frame and the movable end of the hinged frame.

3. ln combination, the main frame, escapement mechanism therein, a magazine throat or entrance hinged to the main frame, a re- .movable magazine between the throat and escapements, a hinged verticallyswinging 'frame to sustain the magazine, and means 'for sustaining said frame in operative position.

4t. In a linotype-machine, the magazine and its base-frame, in combination with the main 'frame having the overhanging arm spanning the magazine, and detachable connee/tions between the mainframe and the opposite sides of the magazine-frame.

5. In a linotype machine, a verticallymovable and detachable magazine, arranged. to be moved to its operative position without resistance, in combination with counterbalaneing means tending to carry the magazine to said position.

6, In a linotype-maehine, the combination of the mainframe, a removable magazine, an inclined hinged support therefor arranged to swing downward from the operative position, a spring tending to raise the same to the operative position, and means for securing the support in said position.

7. In a linotype-lnachine, the hinged, vertically swinging 'frame and the magazine thereon, in combination with a lifting-spring arranged to act with decreasing eiiect as the 'frame descends from its operative position.

S. In a linotype-inachine and in combination with the hinged magazine-sustainiiig frame, the rod I, guided at one end and jointed at the other to said frame, and. the spring mounted on said rod.

9. In a linotype-machine, the com bination of a main frame, a distributing mechanism thereon, a removable magazine arranged in receiving relation to the distributer, and a magazine-sustaining 'frame hinged at the end remote from the dis tributejr, to swing upward and downward.

In testimony whereoil I hereunto set my hand7 this 14th day of March, 1905, in the presence of two attesting witnesses.
