MACHINE FOR STICKING PINS.

Specification of Letters Patent No. 10,372, dated January 3', 1854:.

To all whom. it may concern Be it known that 1, JOHN B. TERRY, of the city of Hartford, State of Connecticut, pin manufacturer, have invented, made, and applied to use certain new and useful Improvements in Machinery for Sticking Pins in Rows into Paper; and I hereby declare that the following isa full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein Figure 1, is a side elevation as with the frame on this side removed; Fig. 2, is a front elevation; Fig. 3, is a plan of the bed and jaws for crimping the paper as with the conductor and feeding wheel removed;

Fig. 4, is a sectional elevation of the jaws and parts attached and Fig. 5, is a cross section as through the line A B, of Fig.1.

The like marks of reference denote the same parts. g

a, is the frame of the machine of wood or metal with two standards I), at the back end carrying by a frame 1, the hopper 6 one end of which rests on the upper end of the inclined conductor 0, which at this point is formed as a trough, with a split in the bottom large enough to allow the shaftsv of the pins to pass into the split while the headsa-re retained above. The upper end of the conductor has a click or ratchet 2, resting on a ratchet pinion 0 on a shaft in the standards I), to which a rotation is given by any proper means so as to shake g or jar both the hopper and conductor, and cause the pins that are placed in the hopper gradually to fall into the conductor and.

slide down, and any pins that are not caught by their heads and slide in the conductor into asuitable receptacle 3 shown here as on a standard attached to the frame a, and

a curved guard 0 allowsthe heads of the pins to pass but prevents any surplus ofv pins from sliding down on the lower part 0 of the conductor, which is attached to a vertical split conductor al supported by astandard to the bed 72.. The junction between this inclined and vertical conductor is made by a split roller so set as to match with the faces of the conductors and is on a shaft with a pulley t, to which motion is given by a belt or other means so that the surface of the roller travels quicker thanthe speed of the pins as they slide down the conductor 0 by this means they are compelledtoturn from a verticalto a horizontal position and I are forced down the vertical part (l of the conductor and fed quicker into the machine than they could be by their gravity only.

" e, is a wheel on a horizontal shaft 5, in

bearings 6, on the bed It, that sitsagainst cumference, at proper distances apart, and

the diameter of this wheel'is such as toreceive notches for three, four or more rows of pins around its circumference. To this wheel 0, an intermitted rotary motion is given so as to bring each successive row of pins intoa proper place to be stuck into the paper.

6 is a ratchet wheel on the shaft 5, with as many teeth as there are rows of grooves for the pins in the circumference of the wheel 6. t

'6 is a radius bar on the end of the shaft 5, carrying the click 8, kept to the wheel 6 by a spring 9.

10 is a curved slide attached to the end of the bar 6 passing within an opening or. mortise in the uard c and sittin close against thewheel c,see dotted lines in 2. v

keeper piece or circular f, is a descending rod attached at its'upper end to the bar 6 the lower beingconnected at 11, to the side of a radius bar f on a center 12, on theframe or. To thebar f is a vertical rod with a helical expansive spring f around it abutting at. the lower end on a cross piece 13, through which the rod passes freely. i I A 1 g, is .a horizontal shaft supported in bear ings 1 1, on the'frame a, on. the end of which is acrank handle or pulley 15, to which power is appliedto rotate the shaft. 9 is a cam attached on the shaft g, which taking the bar f depresses it. the proper amount, and sliding off the end allows the spring P, to throw the bars f andf, up

with a sudden motion taking up another notchon the wheel 6 and in its descent by the actionof the cam rotating the'wheel; e, each notch of which as'it passes under the conductor (Z receives a pin, which pins are kept in place by the guard 6 and sustained by the circular slide 10, sit-ting close to the wheel e, and moving with it when operated on by the click 8, and bar c ,retains the pins in the notches in the wheel 6, until the cam slidin off the bar 7, allows the.

J a a spring f to throw up the click and bar e with a sudden motion, which also draws with it the circular slide 10, allowing the pins to drop onto a jaw 17 set in slides on the bed h, as hereafter described. It will thus be seen that the whee-l e, is filling with a slow motion while the pins are being stuck and then the pins are dropped suddenly ready to be stuck, in the next row, thereby saving the time required by the reciprocatingbed in being filled before the pins are stuck.

1 6, are supports connecting and sustaining vertical dividing plates 2', resting on the jaw 17 and extending up to the wheel 6, and having notches next the wheel 6, to pass the circular slide 10. The dividing plates 2', occupy spaces as shown, bet-ween where each pin is dropped, so that each pin falls onto "the jaw 17 between the dividing plates;

1 i is a fiat bed set in slides 18, having fingers i to pass between each pair of dividing plates i, and press the pin forward through the paper which is crimped and prepared to receive the pin as hereafter set forth. The bed 27 receives an. alternating motion by a connecting rod '6 attached to a standard 19, on the under side of the bed 2 which rod 2' is connected at the other end to a vertical radius bar i jointed at its upper end to a standard on the bed It.

is, is a miter wheel on the end of the shaft g, gearing to a similar wheel h on a cross shaft Z, in bearings 21, on the frame a, on

which shaft is a cam Z operating in its rotation against the bar 2' to draw the bed 7?, forward and stick the pins and then taking a projection 22, on the side of the rod 2' the cam Z forces the bed 2' back again.

The jaw 17 on the side opposite to the sliding bed 2, has a cross piece 25. raised slightly from its surface with grooves cut jawl7, V

27 is a sliding bar fixed on the under side of the jaw 17, and 28 is a similar bar fixed on the under side of the jaw 26, these sliding ' bars 27 ,and 28, pass througlr slides 29,;

on the bed It, and serve as guides to cause the jaws 17, and 26, to remain parallel to the cross bar 23. 30, is a curved bar attached to the slide 27 and passing over and near the side of the shaft Z, and 31, is a curved bar attached on the under side of the slide 28, turning down and stopping short of the shaft Z, 011 which shaft are two small cams 33, set on opposite sides of the shaft so that each rotation of thefl shaft l, the jaws 17 and 26, are drawn close onto the bar 23, and as the cams relieve the bars 30 and 31 the vertical parts are drawn together and the jaws separatedby a spring 32; or the bars 30 and 31 may be formedas forks on their ends sitting over the shaft so that the cams in their rotation both 1 close and open the jaws 17 and 26. a

m, is a cam on the shaft Z, taking against l, a vertical bar n, which is kept to the cam by a spring 34, and at the upper end is connected with a frame a set and moving on centers 35 on the bed It, the end of this frame near the wheel'e, is formed as fl fGIOSS bar 0, that whendepressed coincides" with the cross bar 23, and on the sidesof this bar 0, are plates of'metal forming a rabbet that passes down on each side of the bar .23. 36,

is a roller on the side of the crimping bar 0,

next the wheel 6'. I The operation'of this part is that the cams 33, and m, being timed with the other parts and with: themselves, the paper being led from the roll 39, over the roller 36, and drawn out as hereafter set forth the crimping bar 0, depressesthe paper over the bar 23, and holds it there until the jaws 25 and26, coming up and by small pins projecting from their faces hold the paper, at the same time the cam m, passing clear of the lever n, the spring 34, raises the crimping bar 0, out of the way and the jaws 17 and 26, come tight against the bar 23, holding the paper at right angles to the points of the pins asthey are forced through q, is a roller in journals 37 on the frame a, and r, is another beneath, the shaft. of which passes through the frame and has a ratchet wheel 38, outside, see dotted lines, in

Fig.1, with a click on a rod 39, connected to the upper end of a bar rt, that is jointed at the lower end to the frame a, and hasa contractile spring 40' to keep the bar 0,

againsta cam s, on the end of. the 'shaft- Z;

the size ofthe teeth 'on the wheel 38 isto besuch that the roller 1', will takeupjas-i much paper as is required for each row of pins. i

i t, is a large drum on a hanging frame 41, on the frame a, with a contractile helical spring 42, behind it and around the roller (1,?

and drum is an apron or band &3, that in. sitting against one side of the roller 1, gives sufficient pressure to draw the paper with the pins in it and deliver it complete below.

It will be evident that the wheel 6, may be made as two disks with corresponding notches in their edges instead of the flat faced wheel shown herein, and also it will be seen that the jaw 17 may have slight concavities on its upper side into which the pins fall.

I am aware that a wheel has been used to feed the pins down successively; but I am not aware of any wheel having been made that brings a row of pins to the proper place and then drops them by the withdrawal of the circular slide 10.

I am aware that the fingers 2' have been used to force pins into paper, and as this part is nearly the same as the means used 6, and spring F, or its equivalent whereby the pins are brought from the conductor and dropped at the required place as described and shown.

In testimony whereof I'have hereunto set my signature this twenty fourth day of May one thousand eight hundred and fifty two.

JOHN 13. TERRY.
