Specification of Letters Patent.

Patented Nov. Ml, 19114.

Original application filed. May 29, 1911, Serial No. 630,203. Divided and this application filed November 25,1913. Serial No. ceases.

To all whom it may concern:

Be it known that we, HER ERT PEARCE and JOHN Ennnsr BILLINGTON, subjects of the King of the United Kingdom of Great Britain and Ireland, residing at Linotype and Machinery Works, Broadheath, in the county of Chester, England, have invented new and useful Improvements in Typographical Machines, of which the following is a specification, being a division of the ppplication filed by us on the 29th day of l ay, 1911, Serial No. 630,203.

Our invention relates to typographicalmachines, and more particularly to that type thereof equipped with a plurality of magazines, any selected one of which may be brought into operation at will. A. common example of such machines may be found in British Letters Patent No. 18,579 of 1907, wherein the magazines are arranged so as to be movable upward and downward to bring one or another into operative relation to the distributing mechanism at the upper end and the assembling devices at the lower end. In the patented structure, each of the magazines is provided with its own series of escapements, which control the discharge of the matrices therefrom, and in connection with each escapement there is employed a, so-called pusher, which rocks it in one direction to release a matrix, in opposition to a spring whichrocks it in the opposite direction and returns it to normal position in time to arrest the succeeding-matrix. These pushers are operated by levers known as strikers, which are so located that after they have completed their operating movement, they fall back into position beyond the path of the pushers or the ma azines, and thus permit the latter to be shifted at any instant without interference and without any preparatory operations.

The principal object of our invention is to simplify this construction, and to that end we propose to employ a series of pivoted levers which engage the escapements directly and actuate them, and which normally stand in position beyond the path of movement of the magazines.

' Uther objects will appear from the more detailed description to follow,

The accompanying drawing is a vertical section, showing the series of magazines, the escapements, the throat into which the magazines deliver the matrices, and the escapement actuating devices.

Referring to the drawing, the magazines 9, l0 and 11, containing the matrices 1.6, 17, are arranged one above another in inclined position, and are suitably supported so as to be movable upward and downward in the manner described inthe above mentioned patent, to bring any selected one into operative relation'to the assembling throat or face plate 5, whichreceives the matrices therefrom. "The magazines are channeled longitudinally, as usual, to receive and guide thewmatrlces, and each is provided with a series of escapements 25, one for each channel. These escapements are pivoted at orv neaiythe middle and-provided at opposite sides of the pivot with upwardly extending pawls 24, which are projected alternately through the lower side of thermagazine to control the escape of the matrices therefrom. Each escapement is formed with a forwardly extending nose or projection 33, by which it is positively rocked in one direction, and with a rearwardly extending tail, by which it is rocked in the opposite direction to normal position by the spring 28 hearing on the, tail.

For the purpose of operating the escapements of the magazine, which is in operative position, we employ a series of pivoted levers 34, which are operated from the keyboard through the ordinary reeds 3, connected to the levers by means of the intermediate rods or links 37, which are pivoted at one end to the reeds, as at 39, and at the opposite end to the levers, as at 38. The levers 34 are fulcrumed on a rod 35 passing through the top ends of a series of fixed partition plates 6, connected to the rear side of the assembling throat, each lever and its respective link 37 being mounted in the space between two adjacent plates.

Each of the links 37 is supported and guided on opposite sides by means of rollers 41 and 42 respectively, which are mounted upon wires 4-0 and 4 1- passing through the partition plates 6. The wire 44 is connected to the wire by the spring 45, and is loosely mounted in the slot 43, so, as to permit the rollers 42 to yield relatively to the opposing rollers 41. The object of this arrangement is to allow the parts to yield in the event that the levers 34: should be held against pivotal movement, as would occur when one of the escapement pawls 24 becomes jammed, it being apparent that in such circumstances the-link 37 will swing about the pivot 38 as an axis, and allow the full upward movement of the reed 3 without exerting any severe strain on the parts.

It will be noted that the levers 34 are so located that in,normal position they lie outside of the path of shifting of the escapements and magazines, thus allowing the instantaneous and unimpeded movement of the latter, althongh when operated they will move into direct engagement with the forwardly extending projections 33 of the escapements, and actuate them to release a matrix, returning thereafter to their normal position.

It will be understood of course that the invention is susceptible of embodiments other than that specifically described above, embracing as it does a construction wherein an escapement is operated by the upward movement of an actuating reed through the medium of a pivoted lever, one arm of which directly engages the escapement, while the other arm is operated by the reed. It is manifest that this construction would be useful in machines of a different ty e from that shown, such, for instance as machines having a single magazine, and further that the arrangement of the parts could be widely varied to correspond to the different uses to which the invention may be put.

Having thus described our invention, what we claim is as follows:

1. In a typographical machine, the combination of a magazine provided with escapements, and actuating means supported independently of the magazine, the said escapements being located in position to be engaged directly by the actuating means, and the said parts being arranged to permit a free and unimpeded transverse relative movement of the magazine and escapement actuating means.

2. In a typogra hical machine, the combination of a plurality of magazines, each provided with a series of escapements, and shiftable as a whole to brin any selected one into operative position, with a series of actuating levers supported independently of the magazines,- the said escapements being located in position on the magazines to be engaged directly by the actuatin levers, and the said levers standing norma ly beyond the path of movement of the magazines so as to permit their free and unimpeded shifting.

3. In a typographical machine, the combination of a magazine provided with a series of escapements, and a series of pivoted levers supported independently of the magazine, the said escapements being located in positio-nto be engaged directly'by the pivoted levers, and the said levers being arranged to permit a free and unimpeded relative movement between them and the magazine.

at. In a typographical machine, the escapement actuating mechanism comprising a longitudinally movable rod or link and guiding means therefor, said guiding means being arranged to yield in the event of undue resistance to said link.

In a typographical machine, the combination of an escapement actuating lever and its operating reed, with a link pivotally connected at its opposite ends to the said lever and reed, a roller on a stationary pivot supporting one edge of the link, a second roller on a pivot movable away from the pivot just mentioned, and a spring holding t e second roller in contact with the other edge of the link, and capable of returning said link into contact with the first roller in the event of its being rocked away therefrom.

6. In a typographical machine, the combination of a plurality of magazines, each provided with a series of escapements, and shiftable as a whole to bring any selected one into operative position, and aseries of actuating devices for the escapements supported independently of the magazines, the said escapements being located in position on their respective magazines so as to be engaged directly by the actuatin devices, and the said actuating devices stan ing normally beyond the path of movement of the magazines so as to permit their free and unimpeded shifting.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
