Jl/ Priil RAPHAEL ROGERS, OF BROOKLYN, NEW YORK, ASSIGNOR TO MER GENIULLER LlNOTYPE COMPANY, A CORPORATION OF NEW YORK.

LlNOTYPE-v o (t/ itl/bom, t nba/,1,1 @mwen/L- I Be it known that', JoHNRArHAEL'RoG-V nns, of the borough of Brooklyn, county of Kings, and State of' N ew York, have inventedv a new and useful Improvement in Linotypelifiachines, of which. the following is a specifi-v cation. illy invention has reference to line-castingr machines of the general organization represented in Letters iatent of the United States to O. Mergenthaler, No. 436,531, commonly sold and known in the art under the trademark. Linotype ln these machines the circulating i' atrices delivered one at a time from the magazine are received upon an inciined carrying-belt and delivered thus successively in front of a'vertical star-wheel r pusher, which acts against their side faces pushes them .successively and laterally to an assembler, where/they are 4composed assembled in line against a horizontally-r .ding resistant.

. eretofore the stai-wheels of square or tri- .en ular form have been constructed. in- `one solid piece, their outermost points or corners ting against the matrices. As these wheels e driven high speed and encounter cone "iderable resistance it is found that they wear away rapidly, so that they are diminished in diameter. .ln setting certain classes matter it is important that the wheels shall retain their original and maximum diante er in order that the length of the composed liney and the location of certain matrice/s therein. may be accurately determined. To this end i construct a star-wheel provided at its outermost points with one, two, r more freoly-revolving bars of angular cross-section, so that as the wheel is rotated the successive bars will be brought into action against th'e'rmatrices, each bar presenting one or another of its flat faces against a met so that it will slide thereover with r less irictional effect, in consequence h it will' tend to draw the lmatrix n to a proper level in the line, While at same time urging the matrix forward 1st the line and finally urging the entire, cuduisc.

sloyment of the freely-rotating angular bars is advantageous in that each bar presents a number of faces any one of which come into action, so that the wear is fin I Specification of Letters Patent. Application filed October 15,1906. Serial No. 338,91.

in an inclined or angular path and are gradually turned to an upright position as they join the line. As each of the rotary bars encounters a matrix its face is seated against the same, so that it acts with a pushing and drawing effect, and as the angle of lthe matrix changes the bar, turning about its pivot, is permitted tb `maintain a close or Hat contact- .against the .matrix until the latter reaches its final position.

A'Inlthe drawings, Figure 1 is a front elevation of Ian assembling mechanism containing my improved vstar-wheel. Figs. 2, 3, and 4: are similar vviews showing the wheel in the various relations it occupies to the incoming matrices. Fig 5 is a perspective view of the star-Wheel and adjacent parts, the front portions of the frame being removed to expose the parts. to view. l

Referring to the drawings, A represents ,the inclined 1continuously-traveling belt, upon which the matrices B are successively received. and from which they are delivered over a stationary guide orsupport O into the assembling-elevatorfD, having in its top a channel'in which the matrices are assembled side by side in line. f

E 'represents an upright yielding resistant mounted on the forward end of a horizontal slide and serving to support the forward end ofthe composed line.

F is a verticallyrevolving star-wheel mountedY opposite the receiving end of the assembler. The matrices, descending successively in front of the star-wheel, are drawn downward and pushed forward successively into the assembler, each matrix being added to the end of the line, and the line is then pushed bodily forward to permit the entrance of the next matriX.-` 1

With the exception of the star-wheel the foregoing parts may all be constructed' and arranged to operate as usual. TlL's wheel instead of being made a solid angular piece,

Aas heretofore, now consists of a rectangular frame or body, 'having at its outermost points or corners the four horizontal bars f, mounted vto turn freely on horizontal pivots or axes'j".

As thestar-Wheel is rotated these bars are fcarried .around successively in a common circular path 1n such manner as to act on the side faces of the downcoming matrices. As each baris free to turn about its own axis within thefwheel, it follows that the descending IOC matrices Willbe acted u on by the bars, vas shown in Figsl to t, eacii bar presenting one face or' another, as chance may determine, against the matrix. As each bar comes into action its active face will seat itselfaeainst the side face of the matrix, andas theatter in descending changes -its angular position the bar Willturn to correspond and maintain the contact of its entire face with the matrix, llpon which it will act with a sliding frictional effect.

It is to be noted fthat each bar has not only -a movement in a circular path--that is to say,

a movement of translation or orbital movement-but also an independent movement around its own axis. A t

In practice it is found lthat the bars having the flattened faces are very efficient in their action and that they will assemb e the matrices at high speed with better etlect than the ordinary solid star-Wheels, the points of which present but a small surface at a time in contact With the matrices. l i

My improved star-wheel is advantageous in that each of the rotary bars, presenting,` a large surface, causes the Wear and friction on the matrices to be distributed over a large surface on the star-wheel,'so that the wheel may be operated for a great length of tin e Without appreciable wear or change in its diameter.`

The Wheel -with the flattened rotary bars is' also advanta eous in that each har presents, throughout t e period of its action on the matrix an extended frictional surface in contact therewith. f

I am aware that a star-Wheel has been pro- Avided with round antifriction-rollers, as Shown in the application of Samuel Smith, tiled October, 1906, Serial No. 338,950, and this I do not claim, my invention being limli ited'to a construction wherein the star-Wheel g is provided with freelyrevolving bars ol' anguiar section having a sliding as distinguished from la rolling movement over the surface of the matrices. Y l I'lavintgY thus described my invention, what I claim isl. In a matrix-assembling mechanism, and in combination with nzeans for delivering matrices successively thereto, a rotary pusher or star-wheel provided with one or section. i
