DELIVERING MECHANISM FOR TYPE-CASTING MACHINES.

Specification of Letters Patent.

Patented May 2, 1922.

Application filed November 9, 1920. Serial No. 422,766.

To all whom it may concern Be it known that l, MAURITZ C. INDAHL, a citizen of the United States, and a resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Delivering Mechanism for Type-Casting Machines; and I do hereby declare the following to be a full, clear, and exact description of my invention, reference being had to the accompanying drawings, forming a part of this specification, and to the characters of reference marked thereon.

My invention relates to the handling of type, more particularly as apart of a typecasting machine, in which types after being cast in a mold are ejected therefrom and carried to a type channel and therefrom deposited in a galley or similar receptacle.

The object of my invention is, generally speaking, to provide a mechanism by which the type grasping jaws of the device, commonly called a type-carrier, for conducting the type from the mold where it is cast into proximity to the type channel may be adjustably opened to correspond with the pointsize of the type bodies being cast in the mold. Another object is to connect such jaw adjustment with the adjustment of the type channel so that the single adjustment of the adjustable type channel block for a particular point size will accomplish a corresponding adjustment of the jaws of the carrier. Another object of my invention is to provide mechanism by which a definite opening of the carrier jaws is maintained in proximity to the matrix seat on the mold whereby,

when a type is ejected from the mold between the jaws of the carrier, the latter will not close upon it until the carrier has moved the type away from the region of the matrix embodying a form of the present invention,

Fig. 2 is a similar view with the type-delivery mechanism adjusted to a different type-size point-wise.

Fig. 3 is an elevation of the mechanism shown in Fig. 1, and

Fig. 4 is a perspective view of the typecarrier, the adjustable channel block, the slide, the connection between the adjustable channel-block and the type-carrier and other related parts.

The type-casting machine, a portion of which is'shown in the drawing is the wellknown product of Lanston Monotype Machine Company; the general organization of such a machine is disclosed in Patent No. 625,998, dated May 30, 1899, and the general construction of the improved type-carrier illustrated herein, is shown in Patent No. 1,149,174, dated August 10, 1915: Both the machine itself and the form of type-carrier referred to are familiar to those skilled in the art, and for this reason and alsofor the reason that the above mentioned patents may readily be referred to, it has been deemed unnecessary herein to illustrate or describe them in detail. Moreover such illustration and description would be needlessly burdensome to this specification without assisting to form a complete understanding of the in vention. F or identifying purposes however certain parts of the machine have been shown: for example, the mold A replaceably mounted on the machine frame and comprising the cross-block a and the mold blade a, the latter gaging the set-size of the type during the casting and acting to eject the type after it has been cast and cooled, the cross-block a being moved to open :a side of the mold cavity to permit of such ejection; the type carrier B; the fixed channel-block C; the movable or adjustable channel block D, the line channel being formed between these blocks; the line hook E and the channel block screw F.

It will be understood that in a machine of this kind each type is individually cast in the mold cavity, the upper portion of which cavity is surrounded by the matrix seat a thegcarrier B thereafter advances and the type is ejected by the mold'blade a to a position between the jaws of the carrier; the carriers thereafter drawn in the opposite direction to 'a position in line with the type-channel formed between the channel channel from which they are subsequentlydrawn by the line hook E and moved thereafter into the'gallery or other receptacle of the machine. 7 I

The type-carrier is moved forward and backward by means of a cam-operated lever v of the spring,

Y The connecting lever 8 to be described hereinafter.

to which the carrier is connected by the rod 67.1 The carrier at its forward end is provided with a fixed clamping jaw b and a clamping jaw b movable relatively to the fixed jaw of the carrier. The operation of the movable jaw is accomplished by the lever b mounted upon the carrier and suitably connected with the movable jaw, the lever being engaged by a stop5, whichas shown takes the form of a Z-shaped bar. The for-v ward bent portion 5 of the bar is adapted to engage with the lever 19 to cause movement of the movable jaw ofthe carrieragainst the resistance of the spring b shown in Fig. 3. This spring maintains the'lever yieldably in a definite normal position shown in Figs. 1, 3 and 4 until by the advance of the type-carrier the lever strikes the stop and is moved against the resistance at the same time moving the movable jaw 19 of the carrier relativelyrto the carrier and to the machine frame. In machines heretofore made and used the stop for the lever b was rigidly secured to the frame of the machine. According to the present invention this rigid stop is replaced by the Z-shaped stop 5, and the carrier is provided with the abutment 6, secured to the type carrier at' theconnection between the body of the latterand the rod 1).. This carrier abutment is adapted to engage with a slide"? mounted on the frame of the machine and having a projection 7 against which the abutment 6 of the carrier strikes at a definite point in its forward movement. The'slide 7 alsohas a depending projection 7 2 to engage with the outer end of the connecting lever 8 p The slide 7 is provided with slots through whiclrthe securing screws 7 3 pass, these slots permitting movement of the slide with respectto the frame. A spring 7 secured atone end to the post 7 on the slide and at the other end to the post 7 fastened to the frame'yieldably' maintainstheslide in afdeiinite rearward or normal position except when moved by the abutment 6. This spring is a stronger spring than the spring Z) previously .re-'

machine and engages at its other inner end with the bent end portion 5 ofv the sto '5; at its center it is pivoted to the center 0 the upper lever S, the outer end of which lever 8 over the pivot 10 is provided with a pin 11 for engagement with the .bar 12 rigidly secured 'to the movable type block D. The opposite or inner end of the lever 8 engages with the depending projection 7 2 of the In Fig. 1 both connecting levers are in alinement, the type block being set for say, six point, type. In Fig. 2 :where' the point size adjustment is for approximately 12 point type, these levers are spread apart at their inner ends. The adjustment of the channel'block D acts through connecting means including the rod '12, the connecting levers 8, 9, and the yieldably mounted slide During the advance of the The adjustment of the channel block au 7 tomatically causes through its connection with the stop 5 a corresponding adjustment of the latter relatively to the machine frame and to the slide 7 The adjustment of the stop causes, in turn, an opening of the jaws of the type carrier corresponding with the point size adjustment of the type channel. Since the latters adjustment corresponds with the point size of the type bodies being cast in the mold, the type grasping jaws of the carrier are caused to be adjustably opened to correspond with such-point size; moreover, the jaw adjustment, being connected with the type channel adjustment, corresponds with the latter and is accomplished by the single adjustment of the movable channel block. This adjustment of the jaws is in practice somewhat wider than the point size of the types themselves so that the type carrier jaws will be opened wide enough to receive and carry the type without 11* no longer control the movable type carmovement of the carrier when the stop 5 ceases to move; in other words, when the slide 7 moving rearwardly due to the action of the spring 7 as permitted to act by the. rearward movement of the abutment 6 of;

the carrier and while so moving rearwardly pushing the inner ends of the. connecting levers 8, and 9 and withthem the stop 5 before it, has arrived at its normal position.

At this point in the rearward movement of A.

the carrier, the jaws,and thetype between them, have arrived at'the approximate posi tion shown in dot-anddash lines in Fig.1,

in" which the matrixiseat a of the mold parent.

has been left behind. At such position the movable jaw 72 begins to close on the type, due to the action of the spring I) and the type becomes firmly grasped and held between the jaws. While in proximity to the matrix seat or in the region thereof the type is confined but not grasped so that a kern or platform of the type resting on the matrix seat may be freely slid along said seat before being grasped by the carrier jaws and drawn rearwardly and, slightly downwardly, as shown in Fig. 8, toward the type channel. The provision of the slideand as sociated parts to miantain a definite opening of the jaws while in proximity to the matrix seat therefore prevents danger of type being mutilated during delivery to the type channel. The adjustability of the stop 5 to provide a point-size opening of the jaws to correspond with the point-size of the type being cast is likewise valuable to prevent type breakage or other mutilation and the connecting of this adjustment with the adjustment of the type channel prevents error in the stop adjustment and contributes toward the ready and easy control of the-machine.

In adjusting the type channel blockD the screw F is loosened and the block moved to make the channel wider or narrower, after which the screw F is tightened, this'bein'g the usual practice. If the channel is widened the bar 12 pushesagainst the pin 11 to move the outer end of upper connecting lever 8, the inner end of said lever resting against the depending projection 7 of the slide 7. The central portion of the lever where it is pivoted to the lever 9 is thus moved one-half the distance that the outer end of lever 8 has been .moved; since the lever 9,pivoted to the frame at 10, is moved half the adjusting distance, its inner end will move the full distance and in the same direction as the movement of the outer end of the lever 8. In thus moving, the lever 9, by contact with the projection 5 of thestop 5, adjusts the stop so that its forward projection 5 is moved to correspond exactly with the adjustment of the channel block D.

An adjustment of the channel block D to narrow the channel. causes in effect a corresponding adjustment of the stop 5, as is ap- This adjustment may not take place simultaneously with the adjustment of the block but will be accomplished on the forward movement of the carrier B relatively to the frame of the machine, the lever 7% of the carrier striking against the proj ection 5 of the stop and sliding it to move the connecting levers 8 and 9 until the pin ll of the lever 8 has come against the end of the bar 12, if it has not already done so due to the action of the lever spring 12 In any adjustment of the block the stop adjustment automatically corresponds with the being cast, when the carrier has reached approximately the dot-and-dash position of Fig. 1'; in other words, when the jaws have reached the region of or are in proximity to the matrix seat a of the mold A. At this point the abutment 6 of the carrier strikes.

the upstanding projection 7 of the slide 7 so that during the rest of the movement of the carrier the slide movesin unison with the carrier. This movement of the slide, against its spring 7 allows the inner end of connecting lever 8 to move and such movement is brought about by the lever b pushing the stop 5 so that its projection 5 acts upon the connecting levers to maintain the inner end of lever 8 against the projection 7 of the slide 7. Thus, when the region of the matrix seat is reached, the slide is moved together with and at the same speed as the carrier and this allows the stop to be moved similarly and in unison with the slide; the I result is that the carrier jaws do :not open further nor do they close but maintain the determined degree of opening to the end of the forward stroke of the carrier.

After the type T has been pushed by the blade (1 between the carrier jaws, the position of the carrier being that shown in Fig.

2. the carrier is caused to move rearwardly. Until the region of the matrix seat has been passed the jaws will. be maintained open, so that the type is ufficiently free to move vertically in the jaws, as may berequired if the type is provided wit-h a kern or other portion projecting-over the matrix seat. When this region has been passed, there is no danger of mutilating the type, and the slide 7 having come to rest in its normal definite or retracted position, the stop 5 is halted in its rearward movementand the lever is permitted to move forward under the action of its spring, thus causing the carrier'jaw b to move toward the fixed jaw 6 thereof to grasp the type. The movement of the carrier continues to the full line position shown in Fig. 1 and the type is ready to be ejected into the type channel by the type pusher. It will be observed that the rearward movement of the stop 5 and of the slide 7 is ac complished by the slide pring 7 and that this spring must be stronger than the lever spring 6 to permit of the proper operation of the device. It is also to be noted that a relatively to said frame, saidcarrier being provided with a clamping jaw movable relatively to the, carrier and a lever operatively connected with said jaw, a stop for engaging-with said lever to cause movement or the jaw, a slide mounted on the frame and having a projection, an abutment carried by the carrier to engage with said slide, said stop being adjustable with respect to said slide and movable in unison therewith.
