TYPE-SETTING APPARATUS. I

SPECIFICATION forming part of Letters Patent NO. 523,745, dated July 31, 1 894.

Application filed January 24, 1894. Serial No. 497,856. (No model.)

To 0055 whom it may concern: A

Be it known that we, LoUIs KOSSUTH J OHN- SON and ABBOT AUGUSTUS Low, citizens of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Setting Apparatus, of which the following is a specificatron, sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

Our invention relates to the class of type settingapparatus in which a plurality of types are forwarded simultaneously and made to converge together as they advance into positlon to be grasped collectively between the thumb and finger of the compositor for removal to the stick.

In our applications, Serial No. 496,396, filed January 10, 1894, and Serial No. 497,854, filed January 24, 1894, we describe and claim certaln means for relieving the hand of the com positor of the labor involved in forwarding the types, and for insuring the forwarding and presentation of new types as fast as those preceding are removed from the case.

In our recent applications named the main object sought is to throw a constantly reciprocating pusher into action to forward the types through an instrumentality actuated by the fingers of the operator while grasping the preceding types for removal, and in our last application, Serial No. 497,855, filed J annary 24, 1894, this is effected by means of an inclined plane interposed in the path of the pusher finger at the latter part of its retractile stroke, said inclined plane being set by a finger push bar.

In all our previous devices the reciprooat:

ing pusher has traveled upon'the floor of its table or upon the floor of the type supporting platform. In the present case the pusher finger travels on the under side of the guiding surfaces which control it continuously. In fact a distinguishing feature of our pres ent application is" that the pusher finger is positively controlled in all positions, and cannot fail to do the work allotted to it.

Our present invention consists in combining and arranging with a plurality of type containing channels, and with means for converging the types upon a common support, a constantly reciprocating pusher which tends constantly to rise to the type platform; a port opener and closer operated in one direction by the fingers of the compositor while in the act of grasping or removing the preceding types and in the other by the pusher finger itself; a guiding surface arranged to centralize the pusher finger with relation to the heels of the types; and an automatic latch or trap for insuring the descent of the pusherfinger at the end of its forward stroke while resetting the push-barvto close the pusher finger port at the rear.

In the accompanying drawings, Figurel, is an elevation, upon an enlarged scale,' of our improved type forwarding mechanism. Fig. 2, is a plan, on a reduced scale, of the parts in the position shown in Fig. 1. Fig. 3, is a side elevation of the mechanism showing the pusher finger. in the act of re-setting the push-bar. Fig. 4, is a similar view showing the position of the parts during the retractile stroke of the pusher finger. Fig. 5, is a detail, showing the pusher finger opposite the port when the latter is closed Fig. 6, an

elevation showing the pusher finger in contactwith the heels of the lowest types; Fig. 7, a front view uponthe same scale as Fig. 1. Fig. 8, is a vertical section upon plane of line 1), 22, Fig. 1. Fig. 9, is a plan in detail of the push bar, reduced scale. Fig. 10, is a vertical section upon plane of line to, w,Fig. 1; Fig. 11, a vertical section upon plane of line 00, m, Fig. 1; Fig. 12, a detail showing the curved guiding surface for the pusher finger at the forward end of its stroke.

The socket piece or support A, for the type containing channels B, may be of any convenient or desired construction, that shown in the drawings being substantially the same as in our application hereinbefore referred to, excepting that the partitions are dispensed with, and the channels rest against each other, being supported 'by a rear shoulderr, and a front plate f, as in the patent to Louis K. Johnson, No. 494,573, dated April 4, 1893. By adopting this construction we are enabled to bring the lower edges of'the type containing channels down to the lowest point, and to putthem in collectively Without danger of upsetting the types. Since the channels are all drawn upon equally in our system of word setting all necessity for a separate support for each channel is obviated.

The type supporting platform a, extends out beyond the front of the socket piece A, and is provided with the converging side walls 0., Ct, ending in the port a through which the forward ends of the types are made to project by the forward stroke of the type finger 19 when the latter is brought into action.

The type platform a, is slotted transversely at a j ustbehind the position which the heels of the types occupy when fully forwarded. This slot a opens into a passage way a the bottom of which is formed by the top of the main platform D, upon which the pusher bar P, rests, in the arrangement shown in the drawings, although the pusher may be supported in any convenient or well known mannor, the essential feature being the employment of a constantly reciprocating type-forwarding device actuated by suitable mechanism.

The pusher-bar P, is shown as reciprocated through the medium of a connecting rod p. To its upper side is pivotally connected one end of an arm 1), having the lateral pusher finger p projecting from its other extremity. A spring 3, is interposed between the upper side of the pusher bar P, and the under side of the vibratory arm 19', the result being that the pusher finger p tends constantly to rise to a higher level, and therefore travels upon the under side of the type platform a, and along the lower edge of the upper guide surface g. This upward pressure of the pusher is slight being but little more than sufficient to lift the pusher finger p and arm p, to their work, so that the frictional contact and wear are little if any in excess of the gravity pusher heretofore used. Instead of the flat spring 8, shown any other form of spring pressure may be substituted, or a counterweight may be employed in lieu thereof, if preferred.

The type platform a, extends backward slightlybeyond the rear of the type contain- Y ing channels B. The pusher-finger rests normally against the under side of the type platform a, traveling back and forth thereunder as the pusher-bar P, is reciprocated. The retractile movement of the pusher-bar P, carries the pusher-finger p beyond the rear extremity of the type platform (1, however, at the extreme limit of the stroke, and the pusher-finger would immediately spring upward above the type platform were it not for the presence ordinarily, of the cut-off c, sup ported upon the rear end of the finger push plate C. This cut-0E a, when the push-plate O, is inits forward position rests with its inclined edge 0, against the inclined edge 0 of the type platform a, as illustrated in Figs. 4 and 5. When the finger push plate 0, is pushed back until the finger-plate c rests against the front edge of the type platform a, as in Figs. 1 and 6, the cut-off c, occupies such a position that a port (1, is formed between the inclined surfaces 0', 0 When the parts are in this position the pusher finger 19 when it reaches the end of its retractile stroke, is raised by the spring .9, through the port 61', and into contact with the curved surface 'i, at the rear of the holder A, which curved surface t', guides the pusher finger 19 to the horizontal guide surface t, formed by the lower edge of the holder A. This guide surface 2', is so formed as to centralize the pusher finger 132, with relation to the type that the pusher finger will encounter the heels of the type midway of the width of the latter, as illustrated in Fig. 6. As the forward stroke of the pusher continues the types are forwarded until their front ends project through the port a similar to the manner set forth in our prior applications. Just prior to the completion of the forward stroke the pusher finger encounters the curved surface 4?, which guides it downward below the type platform a. At the same time it also encounters the edge of a spring latch L, pivoted at Z, to the frame. This latch L, yields before the pusher finger until the latter has been guided by the inclined surface 7?, below its lower edge Z, when, under the action of the retractile spring Z it springs back into its normal position, thereby preventing the possibility of the pusher finger rising under theintluence of the springs, before the pusher finger has been fairly drawn under the type supporting shoulder a. The latch L, is held in its normal position by a stop Z and may be of any suitable form or construction other than that shown, its function being simply to insure positively the descent of the pusher finger while the latter is resetting the finger push plate 0. This resetting of the finger push plate (3, is efiected by reason of the contact of the extension 133, of the pusher finger picomingin contact with the arm 0 projecting upward from the-plate C. The arm 0 is so placed with relation to the cut-off c, and to the finger push o that it is moved by the latter part on the forward stroke of the pusher a distance equal to that of the width of the port d, so as to cause the cut-off c, to close the port, as illustrated in Fig. 3,--the spring latch L, having sprung back above the pusher finger just prior to the completion of its forward stroke.

In Fig. 1, which is enlarged for the purpose of illustration, the pusher finger 19 is repre sented at the instant just prior to its ascent through the port cl. In reality it commences to ascend immediately the port is reached, if open, but it is shown in an arbitrary position in this view in order to clearly show the port.

The finger push plate 0, may be supported upon the frame in any suitable manner. As shown in the drawings it is formed with 1ongitudinal slots 0 through which pass the IIO shanks of set screws e, which press the double ended spring h, upagainst the under side of the plate 0, thereby supporting the said plate 0, against the bottom of the table D, while permitting of its longitudinal movement under the pressure of the fingers of the compositor in one direction and the stroke of the pusher finger in the other.
