` ferent shapesk and sizes and to enable the provide novel means for clamping the sheetV sheets to be uniformly registered in proper,y

printing position in the addressing machine. And a further object vof the invention is to in printing position, Vsaid means being selfadjusting and engaging the sheet at spaced intervals so that it Will always clamp the sheet in fixed erations. y l

rIn the accompanying drawings illustrating a selected embodiment'of the invention Fig. l is a topnplan View of so much of the movable carriage of the addressing machine as is necessary for understanding my invention.l Y j .j

I have shown the invention here in the form in-fvvhich it Was shoWnin the joint api plication aforesaid and adapted for use in an addressing machine wherein severallines of type in an address form on a printing device are distributively lprinted-end to end in a single horizontal line, but the vinvention is not restricted to such an embodiment and may be usedfin printing andy addressing machines of other types. 4 i

Referring to` the ldrawings 3 designates generally a carriage which is' adapted to be reciprocated between right and left for theprintingy operations. The 'carriage' has a Work support 4, an opening v5 anda Shield 6 fastened to the carriage at the openingand position'throughout the printing Opf distributive printing. It will befunderstood i that'in this adaptation of the machine the sheet, which isa term used to indicate broadlya card or ajsheet or any other article to be printed, is arranged on the Work support and over the shield in a proper position tofreceive theprinting impressions from the type `lines through the slots 7 in a predetermined position on the sheet, the carriage being moved so that'the printing impressionsfare made. successively through thesiots. The printingk forms 'may' bathose printing `de- `,vices .which are commonly usedin addressing machines andjwhich` ordinarily have?A three lines of typearranged 'in an `addressform. The irstilnpression, usuallygthe name, will be made through the slot at the left end ofthe shield F ig. '14;.the second impression, usually `the street address, Willbe made through the middle slot,v and the thirdimpression, usulally thetown and State, will befmade through the slotat the ,right end of' the shield. `'The inventiongmay beused in other embodiments ysuch as, for example, an arrangementgfor envelopel addressing. 5. The i operation 1 is, 1 made through an inked Vjribbon and theishieldfis .provided to protect the sheet fronrcontact- Withthe ribbonexcept for the impressien.` i

An arm 23 is pivotally mounted at 24 on the carriage and it carries a clamp 25 which is pivoted midway between its ends 'to the arm atl 26 and carries buttons 27 Vof rubber, felt or other suitable material at its ends to engage the sheet on the work support. The arm is shaped in the form of a housing 28 toreceive the clamp and provide a protection for'the clamp. A spring 29 is arranged on the pivot pin 24 with one end engaged vwith the arm 23 and its other end engaged with the work support 4 to hold the clamp normally in clamping position vand a finger piece 30 is provided on the arm at its pivot end to swing the arm onits pivot against the tension of the spring for raising the clamp above the work support when inserting the sheet. A proj ection 31 on the pivot end of the arm is provided to facilitate moving the carriage from left to right.

The invention provides carriagel devices which can be easily and quickly adjusted for any size or shape sheet to be printed and the clamp holds the sheet in fixed position throughout the Aprinting operations and is especially desirable where there are successive printing operations upon the same sheet after it is registered in one' position. The spaced clamping buttons not only hold the s an addressing machine, an arm pivoted on the work support, an elongated self-adjusting clamp pivoted midway between its ends `on said arm, and friction buttons on said clamp at the ends thereof for engaging a i sheet on the Work support for clamping the sheet rigidly in printing position,

eet against the work support but prevent A f the sheet from .moving iny any direction thereon. The pivotal construction of the clamp enables it toself-adjust itself to any variations inf'thickness of the sheet and to any irregularities there may be in the work4 support.

Y I have described the invention in an ernbodiment which gives satisfactory results but I do not limit it to this particular embodiment and reserve the right to make any kchanges in the form, construction and arrangement of parts that may be necessary to adapt it for different machines or desirable for other purposes and within the scope of the following claims.
