LINOTYPE=MACHINE.

SPECIFICATION formingpart of Letters Patent No. 718,781, dated January 20, 1903.

. Application filed June 19,1902. Serial No. 112,347. (No model.)

.are provided with mechanism in which there are tubes or channels fora set of matrices representing about ninety characters. It is desirable, especially for bookwork, to provide the machines with a much larger number of characters.

In my United States Patents Nos. 608,067 and 610,454 I have described means whereby the capacity of a linotype-machine for distributing, storing, and assembling matrices is largely increased. In said patents, however, this increase was effected by duplicating the magazines and providing means for distributing to a plurality of magazines.

The present invention relates to means for increasing the capacity of single magazines, whereby without increasing their size they are adapted to hold from thirty to one hundred per cent. more matrices than heretofore-that is, the number of channels in the magazines, and consequently the number of different characters represented, may be increased from thirty to one hundred per cent.

The invention includes certain modifications in the matrices themselves and in the distributing devices to provide for the distribution of the additional matrices.

The invention will now be described in connection with the accompanying drawings, in whiohv Figure l is a rear view of the upper righthand corner of the magazine, showing distributing screw and rail. Fig. 2 is a similar view illustrating the operation of the distributor stop devices. Figs. 3, 4, and 5 are similar cross-sections through the distributer, illustrating its operation. Figs. 6 and 7 show the preferred manner of modifying the matrices to adapt them to the distributer. Fig. 8 is a sectional View of the preferred form of the invention. Fig. 9 is a similar view of a modification. Figs. 10, 11, and 12 are details of Fig. 9. Fig. 13 is a front view of a keyboard, Fig. 14 is an showing a shift-key device.

In linotype -machines as heretofore constructed the upper ends of the magazine-channels have been of uniform width, the plates at the entrances being spaced about a quarter of an inch apart. The teeth or ribs on the distributing-rail were likewise arranged to drop a matrix at every quarter inch, corresponding with the magazine -entrances. I have discovered that by making the upper ends of the channels of varying widths to correspond with the thicknesses of their respective matrices thirty per cent. additional matrices may be included in'a magazine of the construction and width now employed, and by modifying the present magazine-entrance construction I am enabled to provide double the variety of matrices now available. In my Patent No. 608,067 I proposed to increase the number of teeth in the matrices from seven to eight pairs, the number of matrices which may be distributed in the standard linotypemachine being limited by the number of tooth combinations. According to the present invention I largely increase the variety of matrices which may be distributed without disturbing the ordinary seven-tooth combinations. In other words, I provide means for adapting the seven-tooth matrices for distribution in magazines containing many more channels than those now in use.

Referring to Figs. 1 to 7, inclusive, of the drawings, 1 indicates the distributing-rail; 2, the rear screw; 3 4, the forward screws; 5, the pulley by means of which said screws are driven, and 6 the stop-pins on said pulley. The magazine M is provided in its upper rear portion with a plate 7, hinged on pintles 8, projecting from the stationary portion of the magazine. A lever 9 is provided with a pin -10, adapted to intercept the pins 6 when the lever is raised by the spring 11. The pin 10 is normally held out of the path of the pins 6 by a stop 12, carried by the hinged plate 7, the rear end 13 of lever 9 normally resting on said stop. The plate 7 is adapted to have a slight longitudinal movement, to facilitate which it is provided with rollers 14, resting on the pintles 8. It is normally held in the position shown in Fig. 1 by a spring 15. When a matrix sticks in one of the magazine-entrances a succeeding, matrix will engage it and move the plate 7 to the left, Figs. 1 and 2, releasing the lever f) and immediately stopping the distributer in a manner well known.

As shown in Figs. 1 and 15, the channelentrances are of different widths, each being but slightly wider than the thickness of the matrices for which itis intended. These channel-entrances are formed by grooves 16 in the front plate of the magazine and corresponding grooves 16 in the rear plate of the maga zine and the hinged plate '7. The cars of the matrices travel in these grooves. In order that the matrices may immediately enter and be guided by the grooves, the plate 7 is carried up beyond the lower ears of the matrices and provided with a transverse groove 17, in which the lower ears travel as the matrices are moved along the distributing-rail. It will be seen that when a matrix is dropped its upper and lower ears are both immediately engaged with the groove in the hinged plate and a moment later with the groove in the front plate. Should a matrix stick in the entrances,tl1e distributing-screws will immediately be stopped, as heretofore explained, and the hinged plate may then be moved back, as shown in dotted lines in Fig. 8, to permit the operator to dislodge the matrix.

.I accomplish the result formerly attained by adding two teeth to the matrix and two ribs to the distributing-rail by providing a supplementary rail 1, having at intervals teeth 18 and intermediate notches 19. This rail, as shown in Figs. 1 and 3, is arranged between the forward distributirig-screws, its upper edge being in line with the lower edges of the lugs of the matrices 20 as they travel on the rail 1.

I modify a portion of the matrices, as shown at 21 in Fig. 6, by omitting the lower corners of the upper ears on one side. A matrix so constructed will drop from any part of the distributing-railthat is, its dropping will not be interfered with by the teeth or projections of the rail 1. A complete matrix 20, such as shown in Fig. 3, can only drop from the distributer when it registers with one of the notches 19 in the rail 1, as in other positions it would be intercepted by the projections 18. By this simple modification of the matrices I am enabled to double the number of seven-tooth matrices which may be distributed by a single distributing-rail. I am also enabled to drop the matrices accurately in the magazine entrances, which are just large enough to receive them. In the above embodiment of the invention two sets of matrices will have the same tooth combinations, but different characters. One set, 20, will be provided with the ordinary square upper ears and the other set, 20, will be provided with recessed ears, as shown in Fig. 6. These two sets of matrices will be released from the rail 1 at the same point. At this point the matrices 20 will drop into their channels. The matrices 20, however, will travel a short distance farther, resting upon one of the projections 18, and will be dropped in the adjacent channel tlnough the succeeding notch 19.

A sin jo rail 1 may be used, the matrices being pre rented from tipping while supported on it by resting against the lower screw 4. By using two supplementary rails 1 1 and cutting away one-third of the matrices on the left side and another third on the right side, as shown in Figs. 6, 7, and 8, I am enabled to distribute three sets of seven-tooth matrices from a rail 1, which has the same combination now required to distribute one set. The operation of distributing three sets of matrices will be understood from the diagram of the rails 1 1". (Shown in Fig. 16.) Referring to Fig. 16, it will be seen that three matrices having the same tooth combination will be dropped into the channel- entrances 16, 16 and 16, respectively, which are indicated in dotted lines. As the matrices reach the channel 16 they will be released from the distributing-rail. The matrices belonging to the channel 16, having their rear upper ears cut away, will drop into said channel. The other two classes of matrices will be prevented from dropping by reason of their rear upper ears resting on the tooth 18 of the rail 1". Of the remaining matrices those having their forward upper ears cut away will be dropped into the channel 16 while the matrices having neither upper ear cut away will be sustained by the tooth 18 of the rail 1 until they reach the channel 16, into which they will drop. In like manner there are three sets of matrices for each combination of teeth, one set having their rear upper ears cut away, another set having their forward upper ears cut away, and the third set having upper ears of the usual rectangular form.

Figs. 9 to 12, inclusive, show means for distributing simultaneously into two magazines. In this form of the invention there are two magazines M M arranged one above the other. These magazines have common partition-plates 30, separated by a comb 31. The alternate tongues of the comb 31are bent forward and guide the matrices into the rear magazine M while the other tongues 31 of the comb are bent rearward and guide the matrices into the forward magazine M. By this arrangement I am enabled to increase the capacity of the magazine to the utmost limit, as the partition-plates are thin and the spaces between them may be substantially equal to the thickness of the matrices. The magazinechannels proper, however, may be made wide enough to permit of free movement of the matrices and may have substantial ribs between them.

In Fig. 13 I have shown means for operating parts of two sets of matrices from a single set of keys. The keys operate a single set of rods 32, which are shiftable by means of a lever 33 to cause them to register with either of two sets of rods 34, arranged upon them, the latter rods being connected with the matrix-delivery pawls. In Fig.14 is shown a keyboard having a single set of rods 32 and a double set of rods 34, the latter connected with the escape-pawls of upper and lower magazines M M While my invention is primarily an improvement inlinotype-machines of that class in which the matrices have V-shaped serrated notches which cooperate with a distributing-rail having a V-section, it will be evident that certain featn res of the invention are applicable to other forms of typographic machines.

I believe myself to be the first to provide an automatic distributeradapted to distribute matrices into a magazine having channel-entrances of different widths, all distributers heretofore used having been adapted to drop or eject type or matrices at points uniformly spaced. In the present invention the channel entrances or throats are adjacent, being separated only by thin plates of uniform thickness. The matrices are liberated from the distributing-rails when they are opposite the center lines of the entrances of their respective channels, and these center lines are unequally spaced; hence the unequal spacing of the distributer-rails.

In the form of the invention illustrated advantage has been taken ofthe ears which ocour on standard linotype-matrices. Certain other matrices have been proposed having no ears, and in such cases I would provide lateral projections to be used in conjunction with the auxiliary distributer-rails.
