LOGOTYPE-C ASTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 791,747, .dated'J'une 6, 1995.

Application filed July 11, 1904. Serial No. 216,045,

/'0 all whom it may concern:

Be it known that I, BENJAMIN F. BELLowS,

a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Logotype-Casting Mechanism, of which the followingisafull, clear, and:

clude the manner of mounting and moving the mold and of clamping the mold between the casting mechanism and the matrix-line, the

2 5 end clamp for the matrix-line, the means for ejecting the Slug from the mold and for trimming it, the mechanism for imparting properly-synchronized movement to the various parts,and the meansfor starting and stopping 3 the mechanism.

The invention may be here summarized as consisting of the construction and combination of parts hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a front elevation of so much of atype-bar-making machine as includes the present invention. Fig. 2 is a plan view of the same mechanism. Fig. 3 is a sectional plan in the plane indicated by 4 line AB on Fig. 7 ,the rear part of the mechanism including the melting-pot and metal-pump,- and the supports therefor being broken away. Fig. 4 is a side view looking in the direction of the arrow on Fig. 1 and showing the mechanism at the left of the line B and in front of the melting-pot and its adjuncts. Fig. 5 is a view, partly in section, in the plane indicated by the line C of Fig. 2. Fig. 6 is a rear elevation of view, of the end clamp for the matrix-line.

The logotype 2 is cast in a slot 1 in a mold-- block 3, attached to a rock-shaft 4. The thickness of this block from front to back is equal to the height of the logotype'less the height of the projecting characters thereon. By moving the rock-shaft .4 the mold may be moved back and forth between a horizontal position, which it occupies when the logotype is being cast, and the vertical position, which it occupies when the logotype is being ejected.

A gear-segment 5 is secured to this rock-shaft in mesh with a gear-segment 6 on the end of the pivoted rocker 7 which rocker is moved in that direction which will cause the movement of the mold into a horizontal position by a spring 8, while it is moved in a contrary direction by a cam 9. When the mold is in a horizontal position,it is between the nozzle 10 and matrix-line. 7 5 The matrix-line is supported upon a shelf 12 of the vertically-movable elevator 13, which shelf when the elevator is down occupies a position in the line with the assembling-rail 14 of the machine from which the matrices are 0 pushed onto the elevator-shelf by any appropriate mechanism. The, elevator at that time rests upon a slide 15, to which is attached the lower end of a vertical bar 16, which passes through the elevator and by which the eleva- 5 tor is guided in its vertical travel. When the mold is in the horizontal position, this slide, with the elevator resting thereon, is moved toward the mold-block, so as to bring the matrix-line against one side-thereof with the 9 characters on the matrices in line with slot 1.

At the same time a hollow slide 17, which serves as a support for the melting-pot and supports the pump 19 and the nozzle 10, connected therewith, is moved to bring the nozzle against opposite side of the mold. The

movements of this slide 17 and of the slide 15 are only about one thirty-second of an inch each;but as they move toward each other they tightly squeeze the mold-block between the matrix-line and nozzle, as stated. These two

slides

15 and 17 are moved backward and forward by means of two toggles 21 22, whose joints are respectively connected by links 23 24 to the single rocker-lever 25.

This lever is moved in .the unclamping direction by the action of the cam 26 on an arm on the vertically-movable bar 27 attached to said rocker, and it is moved in the clamping direction by the action of a spring 28 on said bar 27. Before the mold has been so clamped the end clamp 30 for the matrix-line has been moved by the action of a spring 31 against the end matrix of said line, thereby forcing the matrices tightly against one another or rather thereby clamping the matrix-line between itself (the end clamp) and a fixed abutment 32 at the end of the elevator-rail. The end clamp 30 is pivoted to a sliding end-clamp base 33 upon a horizontal axis parallel with its path .of travel, and it is to this base portion that loosely mounted on shaft 3 1, whereon it may move lengthwise one-half an inch, more or less. In the under side of this end-clamp base is a notch 35, which loosely receives the upper end :is not in-use, it is necessary that it shall not occupy sucha position overhanging the assembling-rail 14 that it would interfere with the free movement of matrices along said rail onto the-elevator-rail, while it is equally necessary that it shall overhang the elevator-rail when it is clamping a matrix-line, because it must then occupy a position in which its rear face shall be in contact with the mold-block, covering so much of the mold-slot as is not covered by a short matrix-line. To get the end clamp to move from one of these positions to the other as it moves to or from its clamping position, the base member has in its top face ,a diagonal slot 39, and a pin 40, fixed to the end clamp and carrying a friction-roller 4E1, enters this slot. When the base member moves back-that is to say, away from the ,matrixlinethe clamping member maintains its horizontal position until the right-hand end of the clamp comes into contact with a fixed stop 29. This prevents further endwise movement of the end clamp, but permits further endwise movement of the base member, the result of which is that the inclined slot in the base member, by its action on the pin 40 secured to lthe clamp, causes said end clamp to be turned up into substantially the position indicated by dotted lines in Fig. 11. When the base member moves to the left, the end clamp being permitted to do so falls under the influence of gravity to the position shown by full lines in Fig. 11. It must occupy this position when it is clamping a matrix-line, because at that time the righthand shoulder on the base member is engaging with the right-hand end of the end clamp. When the matrix-line has been clamped and the mold has been squeezed, a cam 43 has lifted the pump-plunger and then suddenly releases it, whereupon a spring k1 moves the pump-plunger 48 downward and causes the injection of molten metal through the nozzle 10 into the mold-slot. The cam 43 acts directly on an arm 51, attached to a rock-shaf t 52, there being another arm 53 attached to this rock-shaft, which engages with the lower end of a rod 54 to lift the same. This rod is attached by a yoke 55 to the pump plunger-rod 56. \Vhen the pump-plunger has descended and molten metal has thereby been injected into the mold, the two

slides

15 and 17 are moved in opposite directions away from the mold by the action of cam 26, the end clamp is withdrawn, and the mold is rocked to a vertical position by the action of the mechanism described. In passing to this vertical position its rear edge slides against the face of a shearing-knife 15, by which the bottom of the logotype is sheared ofl smooth and square. When the mold reaches the vertieal position, the slot containing the logotype lies between an ejector -16, by which the logotype is pushed from the mold, and trimming knives 47, between which the logotype is pushed and by which its sides and ends are trimmed off smoothly. The logotype after passing between said trimming-knives falls into an inclined chute &9, through which it slides by gravity onto the galley 50.

The ejector-slide 56 moves in a guided horizontal path forward and backward, and the blade-like ejector 4:6,atta'ched thereto, is placed so that when the mold-block is in a vertical position the ejector may enter and substantially fill the mold-slot 1, thereby pushing the logotype out and between the trimmingknives 47. The ejector-slide has rack-teeth 57 on its outer face for the engagement of the gear-segment 58, secured to a vertical shaft 59. This shaft carries a gear-segment 60 near its lower end, which engages with a rack-slide 6.1, and said slide carries a friction-roller 62 in engagement with the cam (53. This cam, acting through the described l'nechanism, moves the ejector-slide in the direction to eject the logotype from the mold. A spring 64:, acting on an arm 65, secured to said vertical shaft, moves the shaft, and consequently the ejectorslide, in the contrary direction.

The described cams are all secured to the sition. The descent of the mold to the horizontal position and the clamping movement of the end clamp are substantially synchronous. Then the two slides and 17 are moved to squeeze the mold between the matriX-line and nozzle, and then the pump-piston, which has beenraised in the meantime, descends and injects the molten metal into the mold-slot 1, thereby forming the logotype. Then the

slides

15 and 17 are separated, the end clamp is withdrawn, and the mold is swung up to its vertical position. Then the ejector moves forward, pushing the logotype from the mold-slot and between the trimmingknives, and thenflmoves back to its normal position. This completes the cycle of the described mechanism, except this: that if this mechanism is used as a part of a logotype making machine the elevator will, as soon as the

slides

15 and 17 are retracted, begin its upward movement toward a point at which the matrices are removed from the elevator-rail. The mechanism for so moving the elevator is not, however, any part of the present invention. Normally the cam-shaft 66 is at rest; but a gear 67 is loosely mounted thereon, and

this gear has on its inner face an annular row of ratchet-notches 68 for the engagement of a clutching-pin 69, which occupies a recess in the proximate end of the cam 63. This locking-pin is under the influence of a spring 70, tending to move it out of the cam and into engagement with one of said notches. In the face of said cam 63, however, there is a groove .71, which intersects said locking-pin, and the locking-pin has an inclined shoulder 7 2 upon it, as shown in Fig. 8. An arm 73 bears upon the surface of this cam in the plane of this groove and'is of such size that it may enter the groove. The end thereof which does so enter said groove is beveled slightly for engagement with the beveled shoulder on the locking-pin. This arm is attached to a rock-sh aft 74:, which is under the influence of a spring 75, which causes the arm to press strongly against the face of said-cam. As the cam 63 rotates said groove 71 is brought around toapoint where said arm 73 enters it and by engaging with the inclined shoulder on the locking-pin withdraws the pin, and thereby disconnects the cam-. shaft from driving-gear, wherefore there is nofurther tendency toward rotating said camshaft. In order, however, that the cam-shaft may not by reason of inertia carry beyond the desiredv point, there is at the end of said groove 71 a shoulder 76, with which the endof the arm 73 engages, and thereby positively stops the further rotation of the cam-shaft.

It will'be understood, of course, that the driving-gear 67 is being constantly rotated. To

set this casting mechanism into operation, it

is only necessary to withdraw the arm 73 from its engagement with said locking pin 69,

whereupon the pin under the influence of its spring flies out into engagement with a notch in the inner. face of said gear. This arm may be so withdrawn either automatically by mechanism (not shown) or by means of another arm 77, also attached to said rock-shaft, to be depressed by the operator.
