mpany Application January 29, 1936, Serial No. 61,261 In Great Britain February 8, 1935 10 Claims.

This invention relates to distributing mechanism of typographical composing and distributing machines such as those known commercially under the trade-mark Linotype of the kind which are provided with a plurality of fixed distributors and a plurality of superposed magazines co-operating therewith. In certain machines of this kind the distributors are arranged vertically one above another, and the magazine entrance which conducts matrices from an upper distributor to an upper magazine, extends inwardly in front of a lower distributor, and the said entrance cannot be moved about a pivot near its lower end, as is usual in machines having step-wise arranged distributors.

It has therefore been proposed, in connection with vertically superposed distributors, to support an upper magazine entrance on pivot studs at the rear of the entrance, resting in open bearings on the distributor frame above the next lower distributor, so that the entrance may be tilted rearwardly about the axis of said studs to give access to the entrance channels, or lifted out of the open bearings and removed from the ma- 25 chine to permit of access to other parts. The

necessity of such removal is avoided in an alternative arrangement according to which it has been proposed to pivot an upper magazine entrance about an axis remote from the respective 30 distributor so that the said entrance may, by an arcual movement as a whole, be moved bodily rearwardly between the distributors to an inverted position at the rear.

The object of the present invention is to provide a construction in which the advantages of the last-mentioned arrangement may be secured, while reducing the range of movement of the entrance and ensuring a more convenient location thereof when in its inoperative position.

To this end an upper magazine entrance according to the invention is arranged to be tiltable about a pivot located at the rear of the entrance and above the next lower distributor, and the said pivot is displaceable in a substantially horizontal direction to carry the entrance from and to the operative position, tilting of the entrance about the pivot being effected automati cally during such displacement, whereby a substantially horizontal inoperative position of the entrance is assured. As a further feature of the invention, means are provided for effecting a suppiemental substantially horizontal movement of the entrance in the inoperative position.

According to a preferred constructional form of the invention, the magazine entrance pivot is carried by a pair of links extending rearwardly over the distributor beam and pivotally connect at their inner ends with the magazine-entrance pivot studs and at their outer ends to a pair of 60 arms'pivotally mountedat therear of the'distributor frame. The last-mentioned arms are preferably extended upwardly beyond the point at which the links are pivoted thereto, so as to constitute operating arms or levers for effecting the rearward movement of the magazine entrance, and co-operating guides on the entrance and distributor frame are provided for effecting the tilting of the entrance.

The invention is hereinafter more particularly described with reference to the accompanying drawings, in which:-

Figure 1 is a side elevation, partly in section of a distributing mechanism embodying one constructional form of the invention, showing an upper magazine entrance in its normal operative position;

Figure 2 is a side elevation of the mechanism illustrated in Figure 1, showing in full lines and in dot-and-dash lines respectively different inoperative positions of the upper magazine entrance,

and

Figure 3 is a rear elevation of a portion of the distributing mechanism, partly broken away and with the lower magazine entrance omitted, with the parts in the position in which they are represented in Figure 1.

The distributing mechanism represented in the drawings comprises vertically superposed distributors I, 2, arranged to deliver matrices into the respective magazine entrances 3, 4, by which the matrices are conducted to the appropriate magazines 5, 6. The upper magazine entrance 3 is supported by pivot studs 7 resting in open bearing brackets 36 secured to the distributor beam 9, the studs 1 being carried in lugs or brackets I0 fast to the entrance.

Each of these pivot studs 1 is connected with a link 26 extending rearwardly above the distributor beam 9 and pivoted at the rear to integral arms 2?, 21 shaft I3 which serves to support the screw the lower distributor. veniently securedto a shaft I3, and the arms I4 of These arms may be consleeve I5 surrounding the 27 extended upwardly beyond the point at which the links 26 are pivoted thereto, thus constituting operating levers by which the movements of the upper magazine entrance into and out of operative position are controlled.

In the drawings, only one arm and link mechanism is represented, i. e., that associated with the left-hand side of the magazine entrance as viewed from the rear. It is to be understood, however, that the said mechanism is duplicated at the right-hand side of the magazine entrance, .and that the following detailed description of the parts applies to both such mechanisms.

The back plate of the magazine entrance 3 is provided at the respective side of the entrance with a lower guide plate 28, and a centre guide pivotally mounted upon the plate 29, as well as an upper guide plate 3|], these guide plates serving to guide the magazine-entrance during its movements into and out of operative position, and to support it substantially as a supporting arm, mounted to turn freely about the sleeve I5. Each supporting arm 33 is formed with a lug 34 which normally extends below the pivotal axis of the arm and is adapted to abut against the underside of the distributor beam 9 when the upper magazine entrance is in the inoperative position. Each supporting arm 33 further rests on a bifurcated bracket 35 secured to the distributor beam 9, by which it is supported against side play.

Normally the parts just described occupy the position inwhich they are represented in Figure 1, and to effect outward movement of the magazine entrance 3 into the inoperative position in which it is shown in full lines in Figure 2, it is merely necessary to pull downwardly the operating levers 21. The downward movement of the said levers first pulls the entrance 3 rearwardly, by the actionof the links 26 connected to the pivot studs 1, to bring the centre guide plate 29 into contact with the inner faces of the bearing brackets 33. As the levers 21 continue to move downwardly and the links 26 and pivot studs 1 continue their rearward movement, the entrance 3 is tilted rearwardly about the studs '1, the brackets 33 engaged by the guide plates 29 acting as fulcrums for its tilting movement.

At the same time, the upper guide plates 30, by engagement with the rollers 32, turn the supporting arms 33 rearwardly until the said arms are arrested by the abutment of their lugs 34 against the underside of the distributor beam 9. At the completion of these movements the entrance 3 has reached the position shown in full lines in Figure 2, in which it is supported by the arms 33 and by the guide plates 28 resting on the brackets 36.

In this position of the magazine entrance 3 access to certain parts of the machine, for example the matrix chute (not shown) by which matrices are conducted to the lower distributor, may still be obstructed by the inner end of the entrance and further rearward movement of the entrance is therefore at times desirable.

According to a further feature of the invention such further movement of the entrance 3 is effected in a substantially horizontal direction, by a supplemental upward movement of the operating levers 21, as will now be described.

By reference to the full-line position of the magazine entrance 3 indicated in Figure 2, it will be observed that at the completion of the movements previously described, the entrance 3 comes to rest with the axis of its pivot studs 1 situated above, and somewhat to the rear of, the axis 39 of the pivots connecting the links 23 to the operating levers 21. Hence, upward movement of the axis 39, provided the links 26 are free to turn clockwise (as viewed in Figure 2) about that axis, will cause the pivot studs 1 and the magazine entrance 3 to move rearwardly. Normally, however, such clockwise turning of the links 26 during upward movement of the operating levers 21, is prevented by means of latches 4|] carried by the operating levers. Each latch 40 is pivoted ing on one end of the latch normally holds the opposite end of the latch in a position closely overlying'the link 26, but just out of contact with the said link to permit of easy manipulation of the latch. When it is desired to move the magazine entrance from the full line position to the dot-and-dash line position shown in Figure 2, the latches 40 are manually adjusted against the action of the springs M to bring them out of range of engagement with the links 26, thus permitting the links 26 to move the entrance 3 rearwardly, as above mentioned. During such rearward movement the entrance rides on the rollers 32 of the supporting arms 33, and when the entrance reaches its extreme outward position of the entrance 3, its inner end is supported by a guide plate 31 at the centre of the magazine entrance back plate (Figure 3) resting on a bracket 33 secured to the distributor beam 3. I

To effect the return movement of the magazine entrance 3 to its operative position after it has been moved to the extreme outer inoperative position, the operating levers 2! are again moved downwardly until the latches 49' automatically pass behind the links 26 under the action of the springs 4!. From this position a full upward movement of the levers 21 carries the entrance back to its operative position, the supporting arms 33 being at the same time returned to their normal position by the hooked extensions 3l of the guide plates 30 engaging the rollers 32.
