Application filed March 12, 1915. Serial No. 13,888.

Tou/ZZ whom/it may concern.'

Be it knowntliat I, THOMAS S. I-IoMANs, a citizenk of the United States, residing at Hempstead, inthe county of Nassau and State, of New York, have invented new and useful Improvements in Typographical VMachines, of which the following is a specifica tion. Y

TheV present invention relates to improvements in typographical machines and more especially to 'those ofthe linotype class and Y of the type adapted lto-handle two-letter matrices adapted tobe assembled at either or both of two levels to position the desired lettersor characters for casting.

Y rIhe primary object ofthe invention 1s to yprovide improved means for handling such matrices whereby they Vcan be assembled at either: o r bothof 'two levelspreparatory to the' casting operation and restored to` a common level preparatory todistribution whereby greater certainty is'secured in the supporting of the matrices at the proper level or levels and in the restoring of the matrices to a common level,rand displacement of the matrices is practically avoided.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the

novel features bei-ng pointed out particu-V larly in the claims at the end of` the speciication.

In the accompanying drawing z-Figure l is a perspective view showing one embodiment of the invention vapplied to the yfirst elevator of a machine-vof the linotype class. Fig. 2 is an elevation of the left-hand side of the upper portion of thelirst elevator,

fand illustrating the 'manner in which the matrices are brought to a? common alinement. Fig. 3 is va view of the same side of the'upper portion of the first elevator showing the matrices assembled at both upper and lower levels and presented to the casting mold. Y y

Similar parts are designated by the same reference characters in theJ several views. In the present linstance, the 4invention shown applied to ya typographical vmachine of the well known linotype class adapted to handle two-character A-nlatrices, 1 vrepresenting the top orhead of the irst elevator, whichmay ,be ofv the customary 'orni, and as is well' lniownlias a rising'andfall Ving to thepresent invention, the front and rear jaws`2 and 3k are permanently heldin fiXedarelat-ion to provide a matrix channel of constant width between them by a spacing block or equivalent means 4. .A bar or meinber V5 is iXed to the top or head of the elcvator and is provided with a rearwardly projecting matrix supporting ledge or rail 6. The jaw structure composed of the jaws 2 and@ and the interposed spacing member 4 is movable bodily or asa whole relativelyV to the stationary ledge or `rail 6. In the present instance, thev jaw structure is attached tothe top orliead of the elevator by: a pivot 7 or equivalentcmeans whereby the jaws mayk swing bodily to carry their lower portionsltowa'rd or yfrom the matrix supporting ledge or rail 6. VMeans, such for'eX- y amplexas a spring 8, is provided to normally `hold the jaws in cooperative relation with the stationary matrix supporting ledge or rail 6, this spring in the present instance being attached to the jaw structure at the point 9 and to the tcp 'orV head of the elevator at the point 10. When the jawsare in'tliis position, as they Aappear in- Figs. l and 3, they are adapted to receive a line of matrices in theV channel between them, and these matrices may be assembled at either ory both of the upper andflower levels.l The matrices M, in Fig. y3,jare shown Vassembled at the lower level` theirfupper lugs'or earsV assembling mechanism at either or both of the two lfevelsdescribed and are in such manner presented to the "casting mold. Howevenafter the easthas been made, the mold withdraws, as fis usual in machines of this class, and the Velevatorrises to an upper pssten Where the matrices-are removed fram the elevator and are distributed andV returned'to the proper channels of the magazine. Inorder to properly distribute the matrices, Vit is necessary to first bring all the matrices in the line to a common level. According to the present invention, the matrices are brought to ak common' level by swinging thepjaws and the line of matrices between them rearwardly or in a direction to carry the lower lugs or ears o-f the' matrices assembled at the upper level out of engagement with the rail or ledge 6, this movement of the jaws taking place in thel present instance about the pivot or axis 7. The jaws are shown in a position tobring the matrices to -a common level in Fig. 2, the upper level matrices being carried out ofengagement with their supporting ledge ori rail being free to drop down-to aline with the lower level matrices. The 4bringing of the matrices to a common level occurs during the latterY portion of the upward movement of the elevator, and any matrices which might remain at the upper level, notwithstanding'the removal of the same from their supportingledge or rail, will be pushed downto the lower levelby the bar 14. In the construction shown, a lever is employed to swing the jaws and the line of amatrices into a position to bring the latter to a common level, this lever in the present instancebeing vsuspenjdedfto swing from the pivot 7 and is provided with an abutment,

preferablyin the form of an adjusting screw 16, to bear against the forward side of the jaw structure. v A'track 17 is suitably sup' Y ported, preferably in fixed position, and is arranged to coperate with a projection 18 onthe lever 15. This track is so shaped and positioned that, as theV elevator rises toward its upperposition, the projection 18 y on thejlever 15 engages or travelssalong the jcarries the projection 18 on the lever 15` rear side! of an inclined track,thelever being thereby swung rearwardly,pcarrying with it the jaws, the latter being thus brought into the position shown in Fig. 2 when the elevator has` nearly reached the limit of its'upward The final upward movement of the elevator to a position above the upper end of the track 17, and the lever'15 together with the jaws will swing forwardly under the influence of the spring `8` or under the influence of the weight of the jaws, the latter being thereby Arestored to normal operative relation to the matrix supporting ledge or'rail 6. During the next descent of the elevator, the projection 18 on the lever 15 travels along the forward side of the track 17 until it passes beyond the lower end of the track, whereupon its projection 18 swings forward, bringing it into a position to travel along the rear kside of the track during the next lifting movementof the elevator, and the screw or abutment 16 is brought into portion 17a of the movement.

operative position.y It'will therefore be understood that,kduring the upward movement of the elevator, the elevator jaws are carried the matrix supporting rail 6. 1n order toreturn the lever 15'to operate upon the elevator jaws after its projection 18 has passed beyond the lower end of the track, a spring 19 is pro-vided which may befixed, for example, tothe vise jaw 9., and this spring is arranged to operate upon either side' of a projectionQO on the lever 15 adjacent t0 the pivot 7,. l/Vhen the spring`19 acts upon one side of the vprojection 20, as appears in Figs. 1 and 2 and in full lines in Fig. 3, the. lever-15 is held in position for proper operation to bring the matrices to acommon level lduring each ascent of the elevator. When, however, it is desired to retain Athe matrices at'the different levels in order, for example, to permit re-casting from such line of matrices, or in casethemachine is used whollyin connection witli'matrices which are assembled at the lower level, the lever 15 is swung upwardlyinto the dotted linev jaws, a rail for supporting matrices between i said jaws, the jaws being bodily movable relatively to said rail to carry matrices out ofengagement with said rail, and means whereby said jaws and rail are in operative relation during descent thereof and in inoperative position during ascent thereof, comprising a track, a member cooperative with the track, and means for retaining said member inoperative or inoperative relation with the track.

2. In amachine of the linotype class, the combination of an elevator, a pair of matrix confining jaws connected in lixed relation to one another, and a. rail in fixed relation to the elevator for supporting matrices between saidjaws, the jaws being bodily movable in a direction away from said rail to carry matrices resting thereon out of engagement with said rail.

3. Inamachine of the linotype class, the combination of an elevator, a pair of matrix confining-jaws rigidly connected to form between thema matrix channel Aof fixed width, and afrail in fixed relation to the elevator for supporting matrices in said channel, the jaws being pivoted relatively to the elevator to swing bodily to carry matrices out of engagement with said rail.

4. In a machine of the linotype class, in combination with the first elevator, a matrix supporting rail rigidly mounted thereon, a pair of matrix confining jaws permanently spaced apart and pivotally mounted on said elevator', and meansior moving the jaws to carry the matrices out of engagement with said rail.

5. In a machine of the linotype class, the combination with an elevator, of a matrix supporting rail Xed thereon, a pair of matrix confining jaws pivoted on the eleva@ tor to swing bodily in a direction laterally of said rail, and means whereby the jaws are in operative relation with the .railv during descent of the elevator and in inoperative position during rising movement of the elevator. j Y

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
