Application filed January 29, 1907. Serial No. 354,706.

7 b all whom it may concern:

Be it known that l, Hicimnn (hunsnn, a citizen of the United States, residing in the borough of Manhattan, city and countyof New York, and State oi" New York, have invented certain new and useful improvements in Carriagc-0perating lrlechanism for specification.

This invention has reference to machines in the nature of typewriting machines, wherein by the operation of a set of keys cor responding to various letters, numbers or other characters, such characters are printed or impressed upon a suitable printing or writing surface or member.

The invention l'ias'special application to theiorm. of machines for performing such work by means o'l die members that are in pairs, male. and female, for the purposes of raising or indenting such characters on sheet metal, or other impressionable material. i

The invention isrspeciallv designed for the machines termed redicl'ographs, and patented to W. l Crane, May ll, i897, numbers 582,177 and 532,178. in these relicfographs, there are a pair of cylindri all members carryingthe male and female dies; and these members are rotated to bring the corresponding characters on each into a position a short distance apart. The sheet die members, and thereupon one or both of such members are moved toward the other. engaging the sheet metal between them to raise such cl'iaracter on the metal. The metal plate must. be shifted after each im pression in the manner of a typewriter-carriage movement, so that the impressions aline to produce the desired writing. There must also be a line shil t of the plate to produce the usual succession of lines of writing. in these machines the sheet metal is led in the form of a long strip orweb, and where used for printing addresses, containingabout five or six lilies. the web must be severed between each address. And For facilitating the ron'iovable connection or a number of tl'lese address platcslor use in a printing machine, the plates are removably hinged togetheln, By this means any plate can be together. A construction of this actuating member out of engagement, whereby the carriage is free to be shifted by hand or other mean With these objects in view and others. the invention comprehemls the construction herchia-lter set forth with rcicrenceto the accompauving drawings and particularly pointed. out in the claims.

In the drawings showing el'nbodiments of my invention as applied to a relielograph, Figure Lreyresents a side elevation. Fig. 2 shows in detail the drive pawl. Fig. 3 aview of certain parts of the carriage shifting mechanism shown in Fig. 1. Fig. 4- shows enlarged a plan view of the lever mechanism for shifting the rock bar operating the carriage shifting mechanism. Fig. 5 shows in plan the adjusting pawl and its supporting arm; and Fig. 6 shows the same parts in end View.

The carriage, member, denoted by C. is

moved from it rack 20, secured thereto, theing shown; the rack 20 extending parallel with such rods. On the frame of the 1nachine, denoted generally by M, is a pin. pivot-ally carrying a gear 25 engaging the rack 20, the carriage being advanced by r0- tation of the shaft and gear. A wheel 26, in the nature of a ratchet wheel and per-framing such function, is fast on the shaft 24. in the construction shown the ratchet wheel 26 is provided with crown teeth 27, the opposing sides of adjacent teeth being parallel. A rock shaft- 28 extends along the frame and is supported in suitable bearings. By any suitable mechanism this shaft is rocked at. each operation or one of the keys K to produce an operation of the impression devices, or by means connected with the rock shaft arranged to move the stop member out of engagement with the rotary member upon the initial advance movement of said means to i turn the rotary member, said means being also arranged to release the stop member to 7 permit it to return to loehingposition. and to retain the rotary member locked. until the next advance movement of said means.
