Specification of Letters Patent.

Patented May 1909.

Application filed October 17, 1907. Serial No. 397571 T all whom ti may concern:

Be it known that l, ALBERT ll. Dion, a citizen of the United States, residing at Lake Forest, in the county of Lake and State of 'Illin'oia'have invented a certain new and usefol Improvement in irintingdvlachines, of

which the following is a specification.

This invention relates to printing-machines and has reference, more particularly, to ma:

. 1o chines of comparatively small sizefor use in ollices in roducing multiple copies of-letters and cirou' ars. 1

' The object of the invention is to )rovido a )'i'i11tii1g-'111acl1ine for this use Wl1lC1 can be readily and efficiently operated at compara' tively high speed by an unskilled operator, by whichlett-ers and circulars maybe printed in imitation of type .nittcn work, which is so constmotodthat the type can be readily as sen1hled;'and which canhe maimfactnrod at low cost;

An embodiment of the. invention is illustrated. in the acconnmnying drawings, in

which-- "Figure 1 is a plan view of the machine broken away and sectioned in )art, with some of the parts removed for the. sake of .clearness; Fig. 2 is a central section on line 2? of Fig. 1 Fig. 3 is a detail view of a por- 39 tion of the type-carrying cylinder Fig. 4 is a sectional detail. view hereinafter"referred to Fig. 5 is a detail view of the platen-roller and the support therefor; Fig. 6 is a detail view of a portion of the typecarrying cylinder Figsf and 8 are perspective and plan views, re spectively, of one of the typecarriers; Fig. 9 is a section on line 9-9 of Fig. and Fig. '10 is a section on lino 10-l0 of Fig. Referring to these drawings, the machine to consistsof a base A on which are mounted side-ironies B, 13, these frames carrying the typocarrying cylinder and the platenrolierD; The type-cylinder. C consists of a shaft 0 having heads 0, (Figs. l and 1) selicured to the ends thereof but removable therefrom, the head 0 being held in position by a not '0 threaded on one end of shaft 0,. 'flhe frame '15 is provided with an opening to receive pin Z having a knurled. head 5 and a reduced end b ada ted to enter an monin a a in the end of the shaft 0. A screw 1) t iread- ""ed into an opening in th lran'ie B adapted to engagethe pin 1) to hold it in position. ;'lheother endof the type-carrying cylind 1 tending through an opening in the frame by ineans of its handle, the camsd are to the t )e-carr in c linden The i y 3 g 3 c is similarly supported upon a pin e exism or the platen-oiler ,and'typewa its end entering an opening in the end, shaft 0.

Keyed on pin c is a r lying adjacei t to the end of shaft 0, and the l-ZG gear enters Within a key-Way formed in the wall of the opening in the end of shaft c. so that shaft 0 and the type-carrying c: inder turn with gear a. This gear meshes vs 1 I a pinion. c (Fig. 1) carticd hya shaft which. I, ournaled in e bow-inn formed in the sid e-fran1e B and Which carries at its outer end a crank-pr0- vided with a suitable-operating handle E. B this construction. it will be seen that when the type-carrying cylinder is mounted. in position it is connected to the oporati 5 ha "c E so that it may he rotated thereby ano that the cylinder may he readily withdrawn from its position by loosening the screw 5 and withdrawing the pin 5, in order that the cylinder may he moved in the direction of its axis a distance snflicient to free the end of shaft 0 from the end of pin e.

The platen-roller D is mounted directly below-tho type-cmrying cylinder C and is arranged for adjustment toward and away from the cylinder. For this purpose, the. roller D is carried by a shaft (1, the ends of which are received in slots formed in the ends of arms (1 which are pivoted upon the side--- frames B, B. The. ends oi arms (1 are prcvided with integral ofi'sets a? (Fig. 5 throng which extend. screws (1 which may he hold. any adjusted position by lock nuts (1. 'anc ends of thescscrcws hear on cams o arri by a shaft (i which is rotatable in heal-i forlned'in-the side-frames. one end of shaft being extended through the sidetrai B and carrying upon its end a crank (Z its free end this crank is provided with o )erating handle at and a pin (1", and. the ol this pin is adapted to enter any one oi plurality of depressions d in the side-i B arranged inflanarc about the. of sh. d as a center. When the shaft" (1 turned tated and coact with the screws 03 to the position of the platenroller D relatr is held in any adjusted position; by the ems tion of the end pin (1 with one of tliie prossions (1 For an adjustment grow than thatwhich can he h taincd hyrot the shaft-rd and for obtaining exact p ratchet Q Gasser cylinder, the screws 0 may be positioned as may be required in the openin s in the ofl'sets (1 these screws being then loc lred in position by the nuts d A feed-board F is supported upon the sidefrarnes B, B, opposite the line of eoaction of the t ype-earrying cylinder and the platenroller. Preferably, a sheet-feeding device is provided between this line and the feed: card. This may consist of a air of rollers f, f mounted one above the ot er with their peripheries in contact and connected for simultaneous operation, as shown in Fig. 2; At one side of the machine, a friction-roller f may be provided, geared to the roller f and mounted in position to be engaged intermittently by a sector secured to the type-carry ing drum. This sheet-feeding device forms no part of my present invention and I, therefore, consider it unnecessary to describe it in detail.

The ty e are radially disposed upon the cylinder 3, in lines extending circumferentially of the cylinder. A transfer fabric of a width sufficient to cover all of, the lines of type extends over the type and has its ends suitably mounted u on the cylinder. This transfer fabric may )e a ribbonimpregnated with ink, or it may be an unimpregnated fabric arranged to make contact during each revolution of the ty )eecarrymg cylinder with an inking-rollen 'ihe latter construction is here shown, the inking-roller G (Figs. 1 and 2) beingrnounted above the te-carrying cylinder 0. The ends 9 of thee aft of this roller are received in notches at the to of the side-frames B, B, and 1!; e held in these notches by pins 9.

- Extending between the heads 0, c of the ty 'ie-carrying cylinder C is a bar I, one end of which is received in an opening in the head 0 and the other end of which enters a slot in the head 0 WllliI'O it is hold by a screw 'L (Fig. 3 The bar fis cut away along one edge,

F as shown at i in Figsfl and. 3, to receive a rod i and projections i are formed upon the bar to hold rod i inthe position in which it is shown in Figs. 1, 2 and 3, between projections 1'? and the surface of the cut-away por- {tion of bar I.

g T he transfer itbric J has one end secured Ito the rod and. extends from the rodaround a substantial portion of the type-carrying cylinder .7, and its other end is secured to a )d 7c. T his rod is held in position by a plurality of prongs it carried by a shaft K, which is mounted for rotation in bearings formed in the heads 0', 0 One end of rod 7: extends through the head cand carries a ratchet Wheel 7: (Fig. 6), with which meets a pawl 7-5 pivot-ally mounted upon head (1, Thus, by rotating the shaft K, the transfer fabric may be drawn taut and. the shaft K will be held in this Z having the radiall osition by the 'iavrl it and l I Each line of type is carried by a disk-like type-holder, and the several holders are mounted upon the type-carrying cylinder by removing one of the heads 0, c from the shaft 0, inserting the type-holders u on the a shaft and then replacing the head.- he con- ,struction of the type-holders is shown in detail in Figs. 7 to 10. Each holder consists of two plates l. and M, which are preferably of sheet-metal ressed to the desired form. The plate L t. roughouta substantial portion of its circumference is of greater radius than throughout the remaining ortion, and at its outer edge has an upwar turned flange extending parts Z and l. At the center 01 the plate, -an upwardly extending hub Z. is formed, and at the 11 per end of this hub are a p'luralit -o radially disposed projections-Z The p te M-has a In assem plate L is held in one hand and the type are. placed thereon successively, each t pe being radially disposed-with the-flange entering the notch n therein and the first type being placed-against the Wall Z at the end of the 1 portion of the plate which is. of the greater radius. After a number of type have been assembled, the plate Misplaced in position upon the'assembled type and the plate Land is turned until the notches m therein aline with the projections Z on the plate L, as shown in 1* ig. 7. Plate M is then depressed until it lies below the rejections Z and then turned so that it is held upon the plate L by in t is position, the edge of late M overlies the portions of the type Whic are reduced insize. The assembling of the type can then be continued and after a substantial number 01' type have been placed in position the plate M may be turned around upon the hub of the plate L to hold the type which have been assembled against displacement. The entire space between the Walls Z and Z is thus filled with type or quads, and the plate M is turned on the hub 1 until the portion of the plate which is of greater radius overlies the inner ends of all of the type, so that the latter are held against lateral movement by plate M and against movement radially outward by the llange Z.

l vhen type have been assembled in a sufiicicnt number of the holders for printing the desired matter, these holders are'assernbled the 1projections lies shown in Fig. 8.
