erence being had to the accompanying drawmgs, forming a part of the specification, and to the reference-numerals marked thereon.

My present invention relates to improvements in devices for perforating letters and other documents and apers insuch a way that they may be readily filed away on the well-known receiving-wires, which serve as a binder and the purpose of the invention is to rovide a device of this kind which shall be light and neat in appearance and efficient in 1 operation and which is formed from sheet material to facilitate and cheapen its cost and minimize the manual labor required in its manufacture. J To these and other ends the invention consists in certam improvements and combinations and arrangements of parts that will be hereinafter more fully described, the novel features being pointed out more particularly in the annexed claims 7 In the drawings, Figure 1 is a planview of a perforator constructed in accordance with 'my invention. Fig. 2 is a front elevation of the device shown in Fig. 1, parts being shown in section. fvice with the arts above the line 3 3 of Fig. 2 removed. ig; 4 is a sectional view on the line4 4 of Fig. 1. Fig. 5 is a plan view of a sheet-metal blank rior to its beingbent up to form the base Fate and standards. Fig. 6 is a sheet-meta blank before being rolled up to form the shaft. Fig. 7 is a pers ective view of the shaft after being formed, s owing how the end piece is fitted thereto ;and Fig. 8

is an end view of the shaft with the end pieces fitted thereto.

In the several viewsthe same numerals of referencedesignate similar parts.

' Various methods of construction may be employed in carrying the invention into practice; but I generally prefer that shown in the accompanying drawings, the device comprising a subchamber' 1, formed, preferably, of sheet material dished out to form a rece ta- ,cle for the punchings, a cover 2, preferab y of Fig. 3 is a plan view of the deedges as a hinge, and a s ring-catch 4, engaging the opposite edge 0 the subchamber for yieldingly retaining the cover in position as a closure for the receptacle. This chamber or receptacle may be readily stamped into form, andits upper surface is flat, exce t for the narrow shallow depression 5, whio forms a transverselyarranged slot to receive the and having a hook 3 to engage one of the gage 6, the latter being adjustable longitudinally in the slot and provided with a slot 7 for the securing-screw 8, the latter being secured to the lower receptacle, the free end of the gage being upturned to form astop 9.

On the upper flat surface of the receptacle 'and over'the gage 6 is riveted or otherwise secured the supporting-base for the operating parts of the device, comprising a baseplate 10, having the bearing- standards 11 and 12 extending upwardly at opposite sides thereof, and on these standards are carried the guides 13 and 14 to receive the reciprocatory punches 15 and 16, respectively, apertures 17 and 18 being formed in the baseplate in line with their corresponding guides to serve as dies for the punches, which oper ate at substantially right angles to the plane of the base-plate. ably formed of comparatively heavy material and may be best formed from a blank, such as shown in Fig. 5, the standards 11 and 12 being formed by bending up the corresponding wings or extensions into parallelism and at right angles to the body of the blank, the guides 13 and 14 for the punches being formed by rolling up the corresponding forward extensions on the wings for the standards into tubular or rounded form, and as the standards are bent into proper position the guides will rest above'the base-plates, with their bores in alinementwith the apertures 17 and 18 therein, and as the standards and punch-guides now occupy their permanent positions relatively to the base-plate it is preferable to pass a reamer through the bores'of the guides and the corresponding apertures beneath them in the base-plate, as this will bring the apertures of the parts into alinement and will insure an accurate fit of the punches in relation to their guides and the cooperating dies in the base-plate.

The upper ends of the standard are provided with apertures to receive the pivot-pin 19, which extends longitudinally of the co- This plate 10 is .prefercentric shaft 20, the latter being preferably hollow and extending between the standards, and on this eccentric shaft are journaled the connecting devices 21 and 22, which rest immediately adjacent to the mner sides of the corresponding standards and.

act as stops for preventing separating motion of the connecting devices. This eccentric shaft is preferably formed by rolling up a blank similar to that shown in Fig. 6 to form a cylindrical body, the circular edge at each end of the shaft being provided with the dovetail recesses 27 to receive the radially-arranged projections 28 of the end pieces 29, the latter being adapted to fit into the ends of the shaft and secured by any desirable means and are provided with the eccentrically-arranged apertures 30 to admit the pivotpin 19 insuch a way that the shaft 20 will rotate eccentrically about the pivot-pin.

Passing transversely through the eccentric shaft 20, are the arms 81 and 32 of an operating-handle 33, the said arms being provided with segmental recesses 34:,in which the pivot-pin 19 rests while it is in operative position, thus serving as a lock for positively retaining the handle in position, and as this pivot-pin also serves to retain the eccentricshaft in position between the standards the connecting devices will be held in cooperattive relation with the punches.

In operating a perforator of this kind the letters, papers, or other documents to be perforated are supported on the base-plate and inserted beneath the punches and their guides, and one of the lateral edges of the letter is brought into engagement with the stop 9 of the gage, the latter being adjustable as hereinbefore described in order that the perforations may be made in the proper place and at any required distance from its edge.

The operating-handle is so attached to the eccentric shaft that when it occupies the position shown in Fig. 4 the punches will be elevated, and while the paper is in position beneath them the handle is brought forward and pressed downwardly, and this will obviously rotate the eccentric shaft toforce the punches downwardly into cooperative relation with their corresponding dies in the top plate, the punches being thus operated simultaneously to form two or more perforations in the paper, my invention in its present form being shown asapplied to a double or duplex punch.

The punchings of paper are forced through the apertures 17 and 18 of the top plate and are collected in the receptacle beneath and may be readily removed by releasing the spring-catch 4 of the cover, which permits the latter to be removed.

I claim as my invention 1.
