Letters Patent No. 108,859, dated November 1, 1870.

nvlPnOvElvlENT INMA'OHINES FOR'MAKING WOODEN PINS.

The Schedule referred to in these Letters Patent and making parl: of the same.'f

To `whom 'it may concern Be itknown that I, VROYAL HARLOW WATSON, of

Lapeeig in the county of Lapeer andv State' of Michand to the letters of reference marked thereomand being a part of this specilication, -iu which-'- Figure-1 is a perspective view of my machine.

Figure 2 is a plan section of the end of thelever which works the finger which throws the pins down into the hopper.

Figure 3 is a side elevation.

Like letters refer to like parts ineach figure.

The nature of this invention relates tothe construction of an apparatus for the manufacture of-allkinds of wooden pins which require to be pointed previousv to being driven, such as dowel-pins, pins for the fasteningtogether of sash, doors, and blinds, and which may bc easily employed in making rake-teeth, and other similar articles.

The invention consists in a novel method of cutting the pius'from a piece of timber out into the propel' length; also, in a device for pointing said pins, and in a method of throwing them quickly out of the way, and in the adjustability and new arrangement of the various parts, as more fully hereinafter described.v

In the accompanying drawing- A represents atahle, which sustains ,the working part of the'device. I

B are pillarblocks, iu which rotates the shaft C, driven by any suitable power, and the pulley'D.

To the end of this shaft is attached a crank-wheel, E, provided with a suitable wrist-pin, tojwhich is secured, by a proper strap, the pitm'an F.

A cross-head, G, at the outer end of this pitmau, forms a connection with a piston or carrier, H, which has a reciprocating motion inthe hollow guide I.

Upon'the outer end of this piston or carrier is secureda hanger, J, to the lower end of which is' secured a hollow die, K, the boreot` which should be of thelcngth and diameter of' the pin,desired.y

L is a stop and guide, sccuredvto. the table,` and against it rests the timber from which thc'pins are to he cut.

M is an arm, which is secured to the end of'the spring N, and at right angles thereto, in such a mam' ner that the end' of the arm, which is concave, ,will

` strike the end of the pin, which projects through the hollow die K, smartly, when the. spring is released, thereby slightly rounding or pointing vthe pin.

'lhc spring N is secured by the screws a in the jaw O, which is' adjustable, for the purpose hereinafter described, by means of the bolts b and slots e.

P .is an arm, one end of whichis securedv to the cross-head Gr', and has a reciprocating motion there' with, while itsopposite end works in the slotted bearing Q.

To this-arm is secured `a chain or cord R, the Oppositecnd of which is secured tothe spring N.

S is another spring, secured to the table, and 'adj ustable by means of the screw (I and slot e. f

The top of ,this spring is two planes, incliningin opposite directions, and provided with a recess, f, inter'- posed between'the upper ends of the 'inclined planes.

R' is a guide, to hold/the spring N'in place.

'l is a stop, secured to the table, and adjustable by means of the` bolts g g and slots h l1..

U 'is an arm, adjustable by means of the nut i,

which passes through and'projects downward below thejarm P.

V is a lever, pivoted to the table in such a manner that it has an oscillating and vibrating compound mo- A tion. y y

The rear end of this leveris provided with a shoe,

j, with an inclined end, L'.

An arm or cam, l, is rigidly secured to and projects iromthe crank end of the' pitman, F, and, in the rotation of the crank-wheel, strikes the rear end of the shoe, and depresses that end'of the lever;` then, as the rotation progresses, the cam engages with the inclined end of 'the shoe andgives an outward motion to the rear end of the lever, which is pivoted at m, and whose other end has an opposite-motion to those just described.

This lever is compelled to resume its original position by means of the springs W X, to which itis connectedby rods n o.

Y isa spout. through which, and a suitable hole in the table, the pins are delivered into any proper receptacleunder the table, while another suitable hole through the table allows the chips to drop Vto the floor.

The blocks 'of timber, being sa'wn to the length of the pins required, are placed upon the table against the stop L at p', and pushed up until the endis brought opposite the hollow die, which, then, by aforward motion, cuts out the pin. j

' In the continued forward motion of the pitman, the end'of the projecting arm U passes up the inclined face s of the spring S and depresses-the same, letting loose the spring N, which has been held back in the position show-n by the dotted lines.

'lhis spring forces, with aA smart blow, vthe concaved end of the arm 'M against the end of the pin just -out, and points the same.

The continued rotation of the crank-wheel withdraws anni define the die, and also the spring N, until the latter again engages with the recess s, when the block of wood should again be presented for another cut. The cam l is now broughtinto contact with the shoe i, depressing that end ot' the le\'e1"\"',and elevating its opposite end ot' the finger I', which is secured thereto. As the hollow die again advances and cuts another pin, the last one eut pushes the preceding one through the die, when the cam I, engages with the vinclined end kof the shoe, thereby forcing the tinger t above the piu just discharged from the die, when the spring X depresses the l'rout end ot't-helever, compelling the finger to throw' the piu down through the spout. The spring \V then compels the lever V to resume its original position, with its rear end slightly elevated, as shown in the drawine'.

Should pins ot' a longer or shorter length bercquired, thejaw O, stop T, and spring S, maybe adjusted as desired, by the means already described.

For rake-teeth, aiul other similar articles, this machine will be found admirably adapted, while for cutting pills for the purpose specified, it will be found very economical, making a much het-ter and stronger pin than can he made by hand.

messo 2 What -I claim as my invention, and desire to secure by Letters Patent, isi 1. rlhe die K, operated by means of the piston H, pitman l1,erankwhcel1 and shaft C, in combination withthe stop L upon. the table A, constructed, arranged, and operating substantially as and for the purposes herein described. i

2. The arm M, operated by the spring N, in combination with the arm P, chain or cord R, adjustable stop U, and adjustable stop-spring s, constructed, arranged, and operating substantially as herein set forth. l

3. lhelever V, provided with shoe j,and actuated by the springs W' X, in combination with the short beveled cam J, projecting from the pitman, arranged and operating substantially as and for the purposes herein set forth.

4. The combination of the table A, provided with suitable openings therein, with the hopper Y, and stop L, as described, and forthe purposes specied.

YROYAL HARLOVV WATSON.
