TYPEA-SETTI'NG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 523,740, dated July 31, 1894.

Application filed November 23, 1893.

To all whom it mag/concern..-

Beit known that I, LOUIs K. JOHNSON, a citizen of the United States, residing in the city of Brooklyn, in the county of lKings and State of New York, have invented certain new and useful Improvements in Type-Setting Apparatus, of which the following is a specification, sufficient to enable others skilled in the art to which the invention` appertains to make and use the same.

My improvements relate to the class ofl ap paratus in which the types are arranged in .upright columns in prescribed positions in type containing channels, the object of the invention being to facilitate the withdrawal of the lower types as required.

In my application, Serial No. 465,697, filed v March13,1893,Ishowapusherfingeractuating intermediate levers so as toforward the lowest type in a column, actual contact being had with the heel of the type by the upper end of a vibratory push lever. While the arrangement referred to accomplishes the result sought it is still susceptible of improvement since the end of the type forwarding lever has to. pass under and in contact with thcv lowest type while returning to its normal condition after forwarding a type. I obviate this in my present invention which consists primarily in causing the type forwarder to be retracted upon a lower plane than that of the parting from the spirit and intent ofv my invention. In practice the arrangement of parts shown is duplicated for each denomination of 'type to be contained in the setter case as a whole, and I herein illustrate only sufficient mechanism to ygive a clear idea of the novel parts and movements claimed.

Figure l, is a front elevation of three type containing channels provided withA my type forwarding mechanism, the upper portions of Serial No. 491,700. (No model.)

the type channels being broken away, and the type supporting shoulders being arranged at different elevations so as to give clearness for the finger-pieces. Fig. 2, is a front elevation forwarding the type, the lower end of the typev channel being broken away to show the types above the type supporting channel. Fig. 6, is a view similar to Fig. 5, showingl the position of the parts at the moment when the type forwarder is about to advance the lowest type.` Fig. 7, is a similar view to Figs. 5 and 6, showing the type pusher passing under the automatic shunt during the retractile movement of the parts; Fig. 8,` a plan of a single channel and mechanism. Fig. 9, is a horizontal section upon line of y, y, Fig. 5. Fig. 10, is a vertical section upon line oc, Fig. 3, showing'the lower end of the type channel, the socket, type shoulder, dro., without the types and without the actuating parts. Fig. l1, is an elevation of the lower end of a type containing channel. Fig. l2, is a horizontal section upon plane'of line s, z, Fig. 3. Fig.

l'13, is an isometrical view illustrating more clearly the relation of the type'shoulder, type forwarder return slot, and shunt to each other.

The types T, are arranged in type containing channels'O, which latter are supported in any suitable manner in a frame or rack from which they may be removed individually. Any number of type channel supports may be combined in one case, preferably arranged at slightly different elevations/so 4as to permit of the channelsbeing brought into proximity vertically while affording ample clearance for rthe fingers of the operator. As shown inthe drawings, the lower ends of the channels O, are supported in4 the sockets S, which are in turn supported by the frame or rack, orform a part thereof. The lower end of the type containing channel is shown in Figs. 2,4. and l0, one side wall being shorter than theother, so that when the other sidewall rests against TOO the type supporting shoulder s, a transverse slot or opening s', will be left above the type supporting shoulder and said shorter side wall of the channel. Below the type supporting shoulder s, is another slot or channel s2, at the rear end of which is the shunt U. Below the channel s2, is the sleeve or bearing B, formed with the rectangular recess b, in which the shank f, of the linger-piece F rests loosely. To the rear end f', of pusher shank or rod f, is connected the lever G, pivoted at g, to a stationary part of the frame and connecting at its lower end g', with the lever H, which latter is pivoted at 'its lower end h, to a stationary part of the apparatus while its upper end It', is pivotally connected with the type. forwarder I.

As shown in the drawings the upper end of the lever G, is -bifurcated where it passes over a pin projecting from the end of the pusher rod f, so as to compensate for the horizontal motion of the latter, while its lower end g', engages with a slot h2, in the lever H, so as to permit of the levers working freely one over the other.

The shunt U, may consist of any suitable means for automatically closing the rear end of the passage s2, after the passage underneath it of the type shoulder t'. The latter as will be seen from Figs. 9, 12 and 13 projects laterally from one side of the type forwarder I', this shoulder c', alone entering the passages s', and s2.

As shown in the drawings` the" automatic shunt U, consists of an inclined gate or pawl, the upper end of which is pivotally connected at u, to the rear end of the type shoulder s, from which it extends backward at an ineline as will be seen by reference toFigs. 3, 6 and 13.

The upper side of the finger piece F,is at, and is formed upon the same plane as the top or type surface of the type shoulder s. The front wall S', of the socket piece S, is made to act as a front guard to retain all but the lowest type, excepting the one resting directly upon the type shoulder s, within the type containing channel.`

The operative parts tend constantly to maintain their normal positions automatically by reason of a counter-weight W, secured adjustably upon the arm H', of the lever I-l. The adjustment of the weight W, provides for the accurate adjustment and balancing of the parts with relation to the work to be done.

It is obvious that a spring orv other equivalentmechansm may be substituted for the weight W.

The operation of my improved mechanism is. asfollows: The parts being in the position shown in Fig. 3, the operator, using his thumb and finger, pushes inward the finger-piece F, which causes the rod f to throw the upper end of the lever G, over into the position shown `in Fig. 5, the lever G, in turn throwing the lever H, forward. During this for.

' gether, but this is not essential.

ward stroke of the upper end of the-lever H, the shoulder i, of the type forwarder I, advances over the inclined top of the shunt U, comes in contact with the heel of the lowest type (as shown in Fig. 6) and projects the said lowest type onto the top of the finger piece F, and between the thumb and finger of the operator; or in such position that the operator can readily grasp or lift it from the top of the finger-piece. Having performed this function the shoulder t, of the type forwarder I, drops down into the channel s2. As the operator removes his lingers from the iinger piece F, the counterweight W, retracts the operative parts. As the levers G and H, swing back into their normal position the type shoulder t, is drawn through the channel s2, 'and under the shunt U, (as shownin Fig. '7) returning to its former position shown in Fig. 3.

The shunt U, shown in the drawings is supposed to be of suihcient weightto act automatically by gravity, but a spring pawl or equivalent device may be substituted if preferred.

As shown in the drawings and for conven ience in illustration, the socket S, front guard S', type shoulder s, and bearing or support B, are made in one piece or connected to- The several parts named may be` supported independently or otherwise formed as may be found most convenient in assembling a series of channels with their independent type forwarding mechanism in one case.

What I claim as my invention, and desire to secure by Letters Patent, is= 1. In type setting mechanism, the combination of a type containing channel, a type supporting shoulder formed with a channel underneath its type supporting surface, an automatic shunt for closing said channel, and a reciprocating type forwarding shoulder ar ranged and operating substantially in the manner and for the purpose set forth.

2. The combination of a type containing channel C, a type supporting shoulder s', formed with the channel s2, underneath it,

.the automatic shunt U', the reciprocating type forwarder I, formed with the laterally proj ecting type shoulder t', and meansfor reciprocating the said typte forwarder I, substantially in the manner and for the purpose described.

3. The combination of a type containing channel C, type supporting shoulder S,- formed with the channel s2, beneath it, the automatic.

shunt U, the type forwarder I, form ed with the laterally projecting type shoulder 7J, the lever H, the lever G, the rod f, and the finger piece F, the whole arranged and operating substanialtlg in the manner and for the purpose set lThe combination of a type containing channel C, the type supporting shoulder e,
