TO .ALL W-HOMl IT MAY CONCER: f e p Be it known that we, MATTHnw H. Fosrnr. andHUBnnT C. HA'n'r,fot`Unionvillain thecounty inf-Hartford, and State of Connecticnt, have invented certain new and useful' Improvements in AMachine forlllaking Nuts;

anduve do hereby'deelare vthat the following is a full, clear, and exact descriptionthereof, Areference Abeing had to the accompanying drawings, and to the letters of reference marked'thereomfwhich form a lpart'of this ,specication, in Which- Y Figure l is a perspective, showing the cutter in the act of severing. the nut.

Figure 2, a perspective, representing thepunch down. 1 u

Figure 3, a perspective of the reversed sideof'fthe machina-'showing the mode of operating the farmers.

Figure 4, a perspective of the block detached v Figure 5,y a perspective, exhibiting the mann'erof constructing and operating the cutter.

Figure 6 isa section ofthe block, showing `the mode of operating the punch; and

Figure 7 is a. plan, showing the formers in position when not in operation.

.The nature Yof this invention consists, 'rst,` .inr'thej employment ofa movable or sliding' bed for conveying the nut from vthe cutter to the punch and die; second, in the employmentof formers, operating substantially' in the manner hereafter specified; and. third, in the combination ofthe. cutter and punch,.op`erating substantially as' 'will be hereinafter set`forth. I l l To enable others skilled in the art to make and employ our machine, we will now de scribeits construction and operation. l y' A represents. the main bed, furnished with allongitudinal'dove-tail chamber, in which is fitted and slides"V bed-piece or carriage B.' Atv each end' of the main hed, A, are secured Athe supports C-C, upon which the shaft D has its bearings, said shaft being retained in position byboxes, inA the usual way. E is the drivingwheel or pulley, and F the cam-grooved wheel, yby means of which motion is communicated tothe movable bed or cui ringe B. Both of these Awheels are located on shaft D, in the position shown in figs. fand 2.

a,.b, c, al, and'c represent iive cams, arranged also on shaft D, as seen in the same-figures. The peculiar oices of these cams will be fully apparent hereafter.

G represents a metal button, which works inthe cam-shaped groove in wheel F. This button is so secured to carriageB, that it will revolve when thewh'eel is in motion, thus avoiding the rubbingfriction ivhich would otherwise occur. By means of this device, motion is communicated from wheel F to movable bed-piece 0r calL ringe B. l

f fl represent two metal formel-s, working at right angles, to each other, as seen in figs. 3 and 7.' Former fslides beneath'the `casing h, which" is secured to thecarriage, as shown in figs. 2 and 3. Each of these farmers is supplied with springs, z' i', whiohrforce them back-in their` original position, when relievedlfrom pressure.

-I represents a lever, pivoted to the carriage,I one end resting against theouter end of former f7, while its c-is a stiil metal plate, secured upon the periphery of whe-eLF. This 4niet-al plate is'so bent or formed that in the revolutionpof the wheel it4 will engage the lever I, and thus makeit operate formerf;- lc also represents a metal plate, secured to the inner side of wheel F, (see fig. 3.) The lower inner side of this plate is, bevelled, and by it the former f is operated. It should be particularly -observed. that the relative position of both of these. plates 4should be such as to workboth ofthe formel-,s at the saine time. i

k" represents a metal bar, secured to the mainbed A. 7c3v is likewise a metal bar, secured. to bed A. ixume` diately opposite former f.- AThe object of both ofy these bars will be more apparent hereufter.

:c represents a shallow concave metal die, on carriagevB, iig. 7.

-O designates a solid bloc'k, s haped and stepped as shown in riga 4 and 6. This block isrmly secured to the bed A, so that its stepped end will be just beneath the shaft D, or under `cams a, b, c, d, and e. This end of the block is provided with two 4vertical slots', in which the slide m and cutter n work, as fully seen in iigs. rand 4.

o o"represent springs, which assist in pressing up the cutter and slide, when relieved of cams b and d. It

'ivillbe observed that both'the cutter and punch lo, which work in slide fm, as seen in iig. 6, are provided with a notch or slot, in which rest lifter-s 1v and 2. These lifter-s 'are set in small shafts, one cf which is seen in fig. 5. On the end of said shafts are cams, s s', (see iig. 4c.) The object of these cams is to thrownp the cutter and punch when they have been pressed down by cams Za and d, It willbe remarked that the cam d is a triple one, the two outside ones acting upon the slide, while the centre one operates the punch, fully shown in figs. -1 and 2.

trepresents ametal set, at the bottom of slide m. This set has a hole through it, suiiciently large to allow the punch to work freely,

W represents a guide, for conducting the metal to the cutter.

The operationA of oui; machine isf'as follows; Motion is given to the shaft D by means of a band passing over Wheel E. As the Wheel F revolves, motion'is imparted tothe movable bed by the circular button working in the calm-shaped groove While the cutter is up. The metal from which the nuts are to he cut is pushed in guide W. The cutter n now descends and severs the blank, when it falls into die z. The farmers now being operated upon by the metal plates'lc k', come together, and, with the metal bars 7cv and k3, form a squarev box, thus giving the nutthe desired shape. The slide now descending, presses the blank into the concave die, and then follows the punch and drives a hole through'it. The nut, as soon as relieved frein the punch and slide, is pushed'out of the concave dieby the formerf. The next nut, being operated upon in the saine manner, forces the preceding one forward in the groove, and so on until it falls from the m'achine.

Having thus fully described our invention, whatwe claim as new, and Vdesire to secure by Letterslatent, is

1. Sliding bed B, having buttonGr and pivoted lever I thereon, with camlwheel F, providedivith studs 7c c, all constructed and arrangedsubstantially as described.

2. Wefclaim arranging thelczuns a b c d e s s so as to operate the cutter n, slidem, und punch j), subston tially as set forth.

3. The improved n utdnechine, consisting of mechfinism constructed. combined, and arranged substantially as herein set forth.

In testimony that we claim the foregoing as our own, we ailx our signatures in presence of" two witnesses.
