ALFRED W. F. GUEST, OF BROOKLYN, NEW

YORK, ASSIGN OR TO MERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

To all whom it may concern Be it known that I, ALFRED IV. F. a citizen of the United States, residing at. Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine or magazines in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold-filled with molten metal to form a slu or linotype against the matrices which produce the type characters thereon, and the matrices thereaftter returned through a distributing machanism to the magazine from which they started.

More particularly, the invention relates to the distributing mechanism, and is shown by way of example and in preferred form in connection with a special kind of machine, wherein a plurality ofdistributers are arranged in associated relation to each other. However, it will be apparent that my improvements maybe similarly employed in connection with a single distributer, and that no limitation is imposed by their present mode of illustration. In the Mei-genthaler patent. above mentioned, thedistributing devices comprise rotating screws which convey the matrices along a grooved rail or bar, from which they are released at the proper points toreturn them to the ap propriate channels in the magazine, and my invention is herein set forth in connection with that specific mechanism. Obviously, l'ioweveizthe principles thereof are capable of far broader application, and may be adapted to distinctly different styles of distributors, as well as to other forms of typographical machines, as for instance those which handle type or dies instead of matrices.

Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Specification of Letters Patent.

Application filed April 11, 1913.

- ing devices thus to reduce the objectionab Serial No. 760,375.

The application for Letters Patent of J. ogers, Serial No. 687,691, filed A ril 1, 1912, discloses means to arrest positive y the rotating distributer screws, in the event that a type or matrix while in relation thereto 18 improperly retarded, as for instance, if it becomes lodged in the entrance to a magazine and there resists the operation of the screw. The screws are ordinarily synchronously ro tasted or operated, and in the said applies,

tion the parts are so arranged that in the event of undue resistance or other similar derangement, this synchronism will be interrupted, thereby calling into action certain connected devices, which ordinarily run freely, but in such circumstances are thrown out of their normal relations, and as a result thereof interfere and contact with each other so as positively to arrest the further operation of the screws. In connect-ion with these devices, I propose to employ special means for disengaging the driving mechanism in the event that the operation of the distributis retarded, whether this happens because of the action of the parts already described or in some totally difien ent manner. In other words, although this feature may be employed advantageously with the described means for positively arresting the screws. it is similarly applicable to any form of distributor or other mechanism, wherein it may be desired to unclutch or otherwise disengage the driving means in the event of the arrest or retardation of the driven parts. it

In the employment of the specific mechanism above referred to, it sometimes liappens, after the screws are arrested, that an appreciable period of time elapses before the actual disengagement of the driving means, thus submitting the parts to undue strain and possibly to bending or breakage.

It is the principal object of my invention to effect the disengagement of the driving means, or in the form shown, the breaking of the clutch, instantaneously, so as to make the stop mechanism more resonsive and e strain on the parts already mentioned.

Referring to the drawings: Figure 1 is a side view, partly in sectlon, and broken away, of the distributing mechanism and its driving means, with my invention applied thereto; Fig. 2 is a sectional view, taken subsantially on the line 2-2 of Fig. 1; Fig.

- ment with relation thereto.

The matrices X are, as usual, conveyed along the distributer rail Y by the rotating screws D, and drop therefrom into their appropriate magazine channels. The screws D are rotated from the driving wheel A through the clutch member B, which rotates the sprocket wheel C in the manner subsequently to be described, and thence through the sprocket chain C sprocket wheel C and gearing G cept for the difierences subsequently to be described, these parts and their mode of operation are or may be substantially the same as those disclosed in the said Rogers application.

Certain of the screws 1) are provided with the disks D substantially similar to those disclosed in the application for Letters Patent of A. P. Paine, Serial No. 704,958, filed June 21, 1912, constituting supplemental means for retarding or arresting the dis tributing mechanism. These disks are preferably formed with inclined or spiral flanges, and are so arranged that in ordinar operation they run freely in relation 'to eac other, but with their respective flanges or threads always 1n lateral proximity. It

for any reason, (such as undue resistance or the like, as for instance when the matrices X become jammed, as indicated in Fig. 2) the synchronism of the screws be interrupted, the disks will be shifted in angularvv relation to each other, resulting in the lateral contact of their respective flanges and consequently the immediate and positive arrest of the screws. The stoppage of the screws reacts through the sprocket chain C and arrests the sprocket wheel C and thus resists the drivin means, which action and resistance are uti ized to efi'ect the instantaneous .disconnection of the clutch member B in the man ner subsequently to be described. I

The clutch member B is mounted upon the sleeve E, which sleeve is normally pressed into operative position by the spring B in such manner as to engage the clutch member with the wheel A. The sprocket wheel C is attached to the nut S, also mounted upon the sleeve E and engaging therewith by the screw-threaded connection T, in such manner that when the nut is rotated on the sleeve, it is also given a slight lateral move- Rotary motion is imparted to the sprocket wheel C by the spring F, connected thereto and to the clutch member B, the spring having sufficignt strength to cause the parts normally to r0- tate in unison, but adapted to permit a relative movement between them when the sprocket wheel C is retarded previously mentioned.

This action is, however, controlled and overcome, when the distributing devices are arrested'or retarded, by the toggle joint JK and the more powerful spring G, whereby theimmediate breakage of the clutch is efiected. The toggle member J is pivoted at one end to the frame portion M, and at its other end to thetoggle member K,

which is centrally pivoted on-the frame portion N. T he'slide H is connected at one end to the toggle members J and K at their point and at its other end to the spring G, the parts being so arranged as normally to straighten the toggle joint JK, and bring the end K of the member K into contact with the flange L mounted upon the sleeve E, thereby overcoming the force of thespring B and breaking the clutch connection, as indicated in Fig. 5.

The actuating devices are provided with the pivotally (mounted settin handle 0, formed at its upper end with tie projecting portion 0 adapted to engage in such manner that when the handle is moved to the full line position of Fig. 1, the toggle joint J K is broken and the spring G placed under tension, as indicated also in Figs. 2 and 4. In this condition of the parts the clutch member B is held in operative relation to the driving wheel A'by the spring B and in order to permit the continued actuation of the distributing mechanism, the

The lateral shifting of the nut on the-sleeve, due to'the engagement of the groove S with the head P on the detent P, shifts the latter about its pivot and trees it from the stop R, (see Fig. 3), whereupon the handle 0 drops to the dotted line position shown in Fig. 1, the spring G is permitted to act, the toggle J K is straightened thereby, and through the'engagement of the toggle head K with the flange L, the sleeve E is shifted rearwardly against the force of the spring 13,
