loClaims. (Cl. 101-215) This invention relates to printing machines of the hand operated type, the primary object of the invention being to provide a printing machine which will be small and compact and one which may be operated by persons unfamiliar with the art of printing, so that certain advertising matter such as pamphlets showing price lists or the like, may be readily printed.

An important object of the invention is to provide a device of thisv character constructed in such. a way that the type used in forming the letters of the printed matter, may be positioned in the chase in the order in which letters are written in the formation of. words, ignoring all principles carried out in the printing art, and used in type setting.

A still. further object of the invention is to provide a printing machine using a transfer roller and a pressure roller, novel means being provided for automatically elevating the pressure roller from the transfer roller, upon the return movementof the transfer roller, after the machine has been operated to print, thereby preventing blurring of the printed matter transferred to the transfer roller. 1

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and ar'- rangement of parts and in the details of construction hereinafter describedand claimed,1it being understood that changes in the precise embodiment of the invention herein disclosed,

may be made within the scope of what is claimed,

without departing from the spirit of the invention.

Referring to the drawings: Figurel is a plan view of a machine constructed in accordance with the invention. l

Figure 2 is a longitudinal sectional view through the machine. Figure 3 is an end elevationalview of th machine.

Figure 4 is aside elevational view of the machine, portions of the base being broken away. Figure. 5 is a sectional viewtaken on line 5-5 of Figure 3; V

Figure 6 is a perspective view illustrating the construction of the type used with this machine. Referring to the drawings in detail the reference character 5 designates the base of the printing-machine, which is formed with parallel track sections 6, onwhich the carriage 7 operates, the carriage 7 being provided with wheels 8, so that the carriage may slide readily from one end of the base operation.

to the other, during the printing As clearly shown by Figure 2 of the drawings, the carriage? is provided with a partitioning rib 8 disposed transversely thereof, the rib providing a compartment at one end of the carriage, for holding the chase 9 that carries the type, which are indicated by the reference character 10.

The type are of a novel construction, and embody an extension 11 and a head 12, the head being substantially wide, so that portions thereof extend beyond the extensions 11 to the end that when the type are positioned, they may be positype.

Arranged at opposite sidesof the carriageare rack bars 13, which rack bars are engaged by the teeth 14, dis roller 15, sothat posed at theendsof the transfer as the transfer roller is operated,

movement will be transmitted to the carriage to move the chase and type carried thereby to a position directly under the transfer roller. )1

Arranged at points substantially intermediate the ends of the base, and disposed at opposite sides of the base, are spaced uprights 16, which provide a bearing for the transfer roller, the shaft on which the transfer roller is mounted, being indicated by the reference character 17...

-Coiled springs indicated at 18 exert a pressure onthe shaft 17, and normally actito hold the transfer roller downwardly.

At one end of the shaft 17, is mounted the.

pinion 19, whichpinion meshes with the quadrant 20, which is mounted on the shaft. 21,.which in turn isrotated by means of the lever 22.

Thus it will be seen that due to this construction,rotary movement is transmitted to the trans-. fer roller, by the operator moving the lever 22 forwardly and backwardly.

In connection with this movement, it might the ratio of teeth between the pinion l9 and quadrant, is such that with each complete movement of the quadrant, the trans--.

be stated that fer roller will make a complete turn Disposed between the spaced uprights, and arranged near the upper ends, are bearing blocks 23 in which the ends of the shaft 24 are positioned, the shaft 24 providing the support for the pres.- sure roller 25, which acts to press the sheet of paper being printed, into close engagement with the transfer roller, to cause the printed matter on the transfer sheet.

During the operation of the machine, it is necessary for the pressure roller to be elevated, or raised out of contact with the transfer roller, with each reverse movement of the transfer roller, and with this end in view, pivoted segments 26 are provided, which pivoted segments are mounted on the plates 27 which are formed with wide inner ends 28. Y

The pivot pins for the plates 2'7, and which are indicated by the reference character 29 secure the plates 27 to the ends of the transfer roller 15 and are so arranged with respect to the stops 30, that are also secured to the ends of the transfer roller, that the plates 27 may swing downwardly to positions as shown by Figure 5 of the drawings, where the pivoted segments will move inwardly to positions spaced from the periphery of the transfer roller.

This operation takes place while the paper on which the printing is to be transferred, is passing between the pressure roller and transfer roller, the paper passing from the transfer roller after the printing operation. 7

Upon reverse movement of the transfer roller, the uppermost pivoted segment 26, will engage the pressure roller, and further movement of the transfer roller will cause the pivoted segments to swing on their pivots. Since the stops 30 restrict movement of the plates beyond a predetermined point, it will be seen that the segments are extended beyond the periphery of the transfer roller 15, or to positions as shown by Figure 4, wherein the outer edges of the segments will contact with the pressure roller elevating the pressure roller to prevent the smearing of the printed matterwhich has been transferred from the type to the transfer roller.

Coiled'springs 30 are mounted between the bearing blocks 23 and cross bars 31, there being provided an adjusting screw 32- for adjusting the bearing blocks 23, thereby regulating the pressure. directed to the pressure roller, by the coiled springs '30. r

The inking of the type, is accomplished through the. distributing rollers 32, thatare mounted on the upstandingflanges 33, arranged at opposite sidesof the base.

These distributing rollersreceive ink from the ink roller 34 that operates above the rollers 32' in such a way that the peripheries of the rollers 32 contactwith the periphery of the inkroller 34. to the end that ink is transferred from the roller 34 to the distributing rollers 32.

. A handle 35 is secured at one end of the roller 34, so that the roller 34 may be operated to dis tribute the ink placedthereon, over therollers'32'. In the operation of: the device, the chase which has been set with type, is positioned on the carriage in a manner as-descr-ibed. The lever- 22' e is now swung forwardly in the direction of the arrow as indicated in- Figure 4 of the drawings, whereupon the transfer roller is moved in a counter-clockwise direction.

.The carriage together with the chase and the type, are moved to the right end of the machine with the result that the type prints on the transfer roller.

During this operation, the segments 26 contact with the. pressure roller, moving the same upwardly out of contact with the transfer'roller.

A sheet of paper to be printed is now fedbe tween thetransfer roller and pressureroller, and the lever 22 is reversed, causing printed matter to be transferred from the-roller 15 to the sheet.

It is obvious that upon this reverse movement of the lever 22, the segments 26 swing downwardly to positions as shown by Figure 5, allowing the pressure roller to move to contact with the transfer roller.

This operation is repeated, during the printing of each sheet.
