Application filed March 4, 1911. Serial No. 642,212.

To all whom it may concern;

Be it known that I, FRED EUonNaBprorrr, a citizen of the United States, res ding at Philadelphia, in the county ,of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification, reference being had therein to the accompanying drawing,

My invention relates to mechanical movements and more particularly to that class thereof wherein a constant rotary motion may be converted into an intermittent reciprocating motion. In the form illustrated and described it is shown as applied to a keyboard mechanism, Such for instance as is employed in linotype machines to govern the release of the matrices from the ma gazine. Obviously, however, it may be used in various wa s and in ditlerent embodiments, and I 0 not desire to limit myself to any specific form except in so far as such limitations are specified in the claims.

In some respects the mechanism herein embodied is of substantially the same charactor in construction and mode of operation as those presented for instance in United States Letters Patent to Ottmar Morgenthaler, No. 531,266, dated December 18, 1894, and Philip I. Dodge, No. 530,931, dated December 18, 1894. In these patents are disclosed escapement actuating means, wherein the rods or bails are operated by levers which in turn are provided with cams journaled thereon. Each cam is arranged so that upon the release of the operating lever it is brought into engagement with a constantly driven roll in such manner that it causes a complete rotation of the cam. This action efi'ects the two-fold result; first, of reciprocating the rod or bail so as to actuate the escape-ment, and second, by reason of the shape of the cam, of pestering the connected lever to its normal position. In the present instance, instead of such a cam, I employ a gear or driven member which is also normally held out of engagement with the roll or driving member. The driven member is not directly connected to an operating lever, as in the previous instance, but is mounted so as to be capable of motion to and from the driving member, it being normally held out of engagement therewith by a separate and independent device upon which it rests in its inoperative position. Specifically, the

n rma ct. etween t e Q di s e e and the driven member is secured by an cecentrically located part on the latter, which in inoperative and disengaged position rests on the former. When the holding device is tripped in the manner subsequently to be described, the driven member engages with the driving roll and is thereby rotated, and during its movement the eccentrically located part contacts with another portion of the holding device in such manner as to restore it to its original position and thus to leave it in readiness to rengage and hold the driven member when the latter comes to rest.

Referring to the drawings: Figure 1 is a transverse vertical section through the keyboard of a linotype machine, having my invention applied thereto; Fig. 2 is a sectional front view of a part of the same; Figs. 3, 4 and 5 are detail views of the principal parts of the mechanical movement, showlng them in successive operative positions; and Figs. 6 and 7 are detail constructional views.

As is usual in linotype machines, the matrices A are stored in the magazine M and their release therefrom is governed by an escapement B, all in the manner well understood in the art. Each escapement is operated by a reciprocated rod or bail I, the exact connection of which to the escapement is immaterial and constitutes no part of the present invention. As is also customary, the machine is provided with a keyboard having a series of keys 0, whereby. the respective matrices are selected, their delivery being automatically efi'ected through the specific means now to he described. Each key 0 is held in its upward or normal position by a spring I) and is connected by a link E to a pivoted dog or pawl F, which sustains the escapement-rod operating parts in normal or inoperative position. The dog or pawl F is provide with two voperative faces or notches 11 and 12, and its throw is limited by the engagement of a projecting pin G (shown in dotted lines in Fig. l) with the urved slot H (see Fig. 7).

Power is transmitted to the respectively selected rod-operating parts by a constantly actuated roll or driving member 2, located in the keyboard mechanism in position to engage and actuate the driven members of the escapen ent operating devices. This rotational movement of the driving member 2 may be imparted to it in any desired manne as f ns-tam by th be P ll .J-

Patented Oct. 7,1913. 5

Each of the rods or bails I is connected to a driven member or gear 3 by a stud 6 lo' cated eccentrically thereon, and in such manner that when the gear is caused to rotate, the rod will be reciprocated to operate the corresponding escapement. located in a bank or series over the driving member 2 and are separated from each other by a corresponding series of supporting and guiding plates K (see Fig. 7). Each of the gears 3 is formed with a projecting hub or boss 4 (see Fig. 6) which in assembled position occupies the vertically elongated slot 5 in the plate K. The effect of this ar-.

rangenient is to permit not only the rotation of the gear 3 but also a limited radial motion toward and from the driving member 2.

Normally the gear 3 is in its uppermost or inoperative position, as shown in Fig. 1, that is to say, with its hub 4 in the upper portion of the vertical slot 5. This relation of the parts is maintained by means of the separate and independent holding device 7 which is pivotally mounted on the plate K. In the torm'shown, the holding device is provided with two extending branches, an upper arm 8, and a lower. arm 9. The lower arm 9 normally rests in the upper notch 11 of the pivoted dog or pawl F previously referredto, and in this position it supports the gear 3 by reason of the engagement therewith of the eccentrically located part 6.

gages under the upper arm 8 of the holding device 7, thus raislng the latter above its normal position. These relations of the parts are shown in Fig. 4:. When the arm 9 has been thus removed from the notch 12 of the dog F, the spring D previously referred to restores the dog to its normal position, and as the further rotation of the gear 3 carries the eccentrically located part beyond and out of contact with the upper arm 8, the arm 9 will now descend and again rest in the upper notch 11. T rotation of the gear 3 still proceeds and be eccentri-' cally located part 6 again contacts with the angular arranged upper surface of the arm 9, the effect of which rotation'and contact is to withdraw the gear 3 from engagementwith the driving member 2. This position of the parts is shown in Fig. 5. The rotation of the gear continues until the driving The gears 3 are tion, as for instance by holding the connected'key down, the gear 3 will be permitted to engage constantly with the driving member 2, thus resulting in an uninterrupted operation of the escapement or other connected art.

Obviously many variations and changes may be made in the embodiment of myinvention without departing from its scope or spirit, and these will suggest themselves to those skilled in the art. Its advantages are numerous and well defined. There can vbe noslipping between the parts, as in the case of cams, and consequently greater regw larity of action results. The mechanism is self-contained, admits of assemblage without screws or rivets, and may be readily placed in operative position within the keyboard frame-worln'orin a similar manner connect ed to any kind of operating or operated mechanism that may be desired or employed. The parts may be cheaply and rapidly manufactured, as they may be made entirely by punches and dies, and preferably from sheetsteel that may be effectively case-hardened so as to make them almost entirely proof against wear. It is also so compact that a single bank or row of the assembled mechanisms will suffice for a standard keyboard.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is:
