MACHINE FOR STICKING PINS IN ROWS IN SHEETS OF PAPER.

To all whom t may concern:

Be it known that I, .JOHN J.' Hows, ofk

Derby, in the county of New Haven and State of Connecticut, have invented a new7 and useful Improvement on Machines for Sheeting Pins-that is, for Sticking Pins in Rows in Sheets of Paper; and I do hereby declare that the following is a full andv exact description of the construction and operation thereof, reference being had to the annexed drawings, Figures 1, 2,r 3, 4, and 5, which make part of this specification, and of which- Fig. 1 is a perspective view o f an entire machine embracing my said improvement. Fig. 2 is a side elevation.. Fig. 3 is an elevation of the bars for holding the paper. Fig. 4 is a transverse section of said bars. Fig. 5 is a plan of part of the machlne.

The machine represented in the drawings is constructed according to the principles of a machine for sticking pins into papers for which Letters Patent of the United States were granted to Samuel Slocum of Poughkeepsie, in the county of Dutchess and State of New York, which Letters Patent bear date on the thirtieth day of September, A. D. 1841, excepting in so far as the same is modified by the introduction and application thereto of my improvement herein described.

In place of the clamps A A77 of the machine described in the said Letters Patent of Samuel Slocum, I employ the bars a and b, represented in Figs. l, 2, 3 and 4. The bars a and b are so combined and connected with other parts of the machine as to form a ypair of clamps, which may be closed together in a vertical direction as shown in Figs. 1 and 2. The bar b has upon its upper surface two longitudinal ribs, which ribs are divided by a number of transverse notches, the number of notches in each corresponding to the number of pins to be set in a row in the paper, as shown in Figs. 1, 2 and 5. The bar a has two longitudinal grooves on its under surface, Vand also a number of transverse notches orgrooves corresponding to the number of pins. to be set in a row in the paper. The bar b is fastened by screws to an immovable part of the machine, A, as

i shown in Figs. l and 2. The barV a is jointed at Z to t-he lever c, and the lever o'4 is connected by a joint to A at i, Figs. 1 and 2. A spring, f, acts to elevate the lever c and raise the bar a in aV vertical 'direction from the Specicationof LettersPatent No. 2,970, dated February 24, 1843; Antedated December-5, 1842.

upon the bar b, the ribs of the bar Z), are received into the longitudinal grooves of the bar a, as shown in Figs. 3 and 4; and the aforesaid transverse notches of the bars 'a and Z) come together in pairs, so as to form a system of holes or apertures across between sai'd bars, as shown in Fig. 3. Said apertures must be suiiiciently large to allow the pins which are to be sheeted or stuck by the machine to be pushed easily through them, when the bars are firmly closed together. When the bars a and .b are closed, having the paper between them, two folds are formed or raised across the sheet of paper by the action of the aforesaid longitud-inal ribs and grooves of said bars, and sai-d folds of the paper intersect the trans- -verse apertures between said bars above described, so that when the pins are pushed through said apertures they penetrate the two folds of the paper, as is shown in Fig. 4. The red line drawn between the bars a' and b, in said Fig. 4, represents the paper, and a pin is shown intersecting said red line, in order to show how the pins are inserted in the folds of the paper.

V.The sliding hopper C, Fig. 1, the bed g with its system of grooves, Figs. 1 and 5, and the shover h, Fig. 1, are constructed and operate precisely according to the principles of similar parts in the machine for which the Letters Patent aforesaid were granted to Samuel Slocum, and which parts are described in the specification of said Letters Patent. But the cap or plate t, Fig. 1, has a number of teeth projecting downward from its front edge, one of which teethlits into each of the grooves of the bed g, and the system of grooves g are formed in a bed or plate i'itted to slide between guides on the fixed part, A, of the machine, as shown in Figs. 1 and 5, so that the slide D, Fig. 5, (to which t-he plate z, is affixed by screws, as shown in Fig. 1) in being shoved forward to insert the pins in the paper, when it reaches the bed g, pushes said bed forward, until said bed is stopped vby coming against the bar And when the slide D is retracted it strikes against the heads of the screws c, and draws back the bed g, as is shown inFig. 5; said screws v L" being inserted `through holes in the slide D, and screwed fast in kthe vbed vg.v The whole kmachine may be made of brass, or iron or other suitable metal.

Preparatory to using the machine it vis* fastened upon a bench or table as shown in Fig. l, and the leverv 0 Yis vconnected with a treadle in the manner yhereinbefore described. The operator taking a suitable sheet of paperk passes one vend of it rornvbeneath the machine up between the bed g and the bar Z2, and binding it toward the left handy over the bar places itv in va proper position between the bars ay and b. Thebar a beingnow closed upon the bar o by pressing Idown the treadle with the foot, the paper is embraced between saidr bars in readiness for the insertion of a row or' pins. The pins are then distributed in the grooves of the bed g, and being driven orward by the shovel', h, aresthrust through v thekr transverse vapertures between said bars,

and thus inserted in the foldsk of thepaper k in the mannerV herein describedan'd as represented in Fig. 4.' The foot being then removedl from' the treadle Ithe bara will risek and release the paper with the pinsk which have been rlnserted 1n 1t. Y v Y vanced 1n successive port-lons, and the opera- They sheet is ad#V f tio-n repeated, till the required number of f rows are inserted.

I claim as my invention and desire tosein the operation of stickingor sheetingf f pins. f
