Specification forming part of Letters Patent No. 17| ,213, dated December 2l, 1875; application filed October 18, 1875. I

To all whom'it may concern:

Be it known that I, ISAAC iN. BUMBAUGH,

. of Pittsburg, in the county ot' Allegheny and:

State of Pennsylvania, have invented a new4 and useful Improvement in Nail-Separating Machines 5 and I do hereby declare that the following is a full and exact description thereof,`reference being had to the accompanying drawings, and to the letters ofreference marked thereon. 4

My invention relates to an improvement in V nail-separating machines; and consists of a revolving cylinder, in combination with a separating device, consisting of adjustable frames provided with plates arranged with relation 'to each other so as to form a series of V-shaped grooves, said frames and plates beingsuspend-v ed by a spring to a connecting-piece pivoted totwo cranks, whereby a vertical and lateral movement is imparted to the separator, so that the nails are allowed to fall in the different grooves of the separator, and a shaking and agitating motion imparted to the separator through the mediumof said` spring, connect ing-piece, cranks, and two agitatingweights, suspended to arms which are operated by f means of cams,.the whole being so arranged part of my specification, Figure 1 is a side elevation of m y im proved 11 ail-separatin g machine. Fig. 2 is an end view, in perspective, of the separating device. Fig. 3 is a top view of the separating device.

Fig. 1 represents a det-ached view of the plates used for forming the V- shaped grooves, and represents the position of a perfect nailin its travel through the groove. Fig.'5 is an end view, in perspective, of the nail-separating machine with separating device removed froln the connecting-piece. Fig. 6 represents the base or support for the adjustable frame which supports the plates that form the V-shaped grooves. Fig. 7 represents a section of the nail-separator. y

Iii the drawings, A represents 'the l framework ofthe machine,.in which are pivoted four grooved. pulleys, B, and four gear-wheels, C D c f, and a beveled wheel, g. In the grooves of the pulleys B are placed the V-shaped flanges h on the periphery of the cylinder A', which is also provided with gear-teeth i and j, The teeth mesh into the teeth of the wheel g, and the teethj mesh into the teeth ofthe wheels C and D, which mesh intotheteeth ofthe wheels ej', on the axis of which are cranks lo, to which is pivoted the connecting-piece l, to which is attached, by ymeans of aspring, m, the frame a and a checkpiece, o. The frame nis' provided with slots p, for receiving the bolts 1', used for the purpose of holding the adjustable frames s in'- position on thefr-amen.V lBy having the frames s adjustable, the openingsin the bottomv of the V-shaped grooves formed by the plates tmay'be increased or diminished Iat pleasurefor the purpose of adapting the 4separator to the dili'erent sizes of nai ls.` To the framess are attached, by means of bolts or screwsb platefs t, having ange' a, which liange imparts `s tiifness and strength to the plates, an'dprevents Ithem tromwarping, and also hold'si'the nails in'a 'vertical yline in their travel through `the V-shaped groovesf To .the frame'pA, `at o, are pivoted arms w, to` `the-out er endof which are suspended,l by; means of chains o'r cords,"weights The -armsw are elevated by means of cams y on the shaft l', onrthe outer end of which is a pulley, a, for

rotating the shaft l. The arms w and weights :i: are depressed by their own gravity. The check o is used for the purpose of preventing too great a vibration ofthe separator. B represents the ordinary and well-known bluingcylinder,77 which may be used in connection with the nail-separating machine hereinbefore described.

As the skillful mechanic will readily understand the construction of the several parts of the machine, and the relation that said parts bear to each other, I will, therefore, proceed to describe its operation, which is as follows: Power being applied to the driving-pulley c', it will rotate the wheel g, which, meshing into the teeth fi, will rotate ythe cylinder A', and the fteethj,mesh ing into the teeth of the wheels Gand D, will rotate them, and they will roltate the wheels e and j', which willrevolve the cranksk, which will give to the connectingpie'ce l a vertical and lateral motion. which g will give like motion to the separator, (consisting of' the base-frame n, adjustable frames s, and plates t.) bringing the several V-shaped grooves in close proximity to the axis of the cylinder A, and in its vertical movement will come in contact with the suspended weights w, which weights are descending as the separator' is being elevated in its vertical movement, by which, in connection With the check aand curved spring ma jarring, shaking, and

"agitating action isv imparted to the separator,

"cylinder B', to which heat is applied to blue them which cylinder being inclined, as represent-ed in the accompanying drawings, the

revolving off'the cylinder will causel the nails to pass into the cylinder A', through which 'they are carried in such manner by the re volving of the cylinder that the lengthway of the nail will be about on a line with the longitudinalaxis of the cylinder, so that the nails are discharged from the cylinder point foremost, and, dropping on the separator, pass into the several V-sliaped grooves of it, the heads of the perfect nails catching, in the manner indicated in Fig. 4, and the imperfect nails passing down through the openin g' in the V-shaped grooves. The perfect nails, passing alongthe V-shaped grooves, will be deposited at the end of the separator into a suitable receptacle.

The machine hereinbefore described may be applied to nail-machines for the purpose of separatin g the perfect from the imperfect nails,

and depositing them in bins or boxes. The

separating device consisting of the frame n and plates t, check 0,'and spring m may be' used in connection with nail-machines, the shaking and agitating motion being imparted to the separator as a whole by means of a connecting device attached to the heading-lever or other moving part of the nail-cutting machine.

Having thus described the nature, construction, and operation of my improvement, what I claim asof my invention is- 1. A nail-separating machine consisting of a revolving cylinder, A', and a separator provided with V-shaped grooves, said separator having a shaking and agitating motion, substantially as herein described, vand for the purpose set forth.

2. A nail-separator consisting of a revolving cylinder and a separating device provided with V-shaped grooves, and having a shaking and agitating motion, in combination with a nail-blui'ng device or cylinder, substantially as described, and for the purpose set forth.

3. The nail-separator consisting of the frame n, adjustable frames ys, plates t, and check o, substantially as herein described, and for the purpose set forth. v

4. In a nail-separator, the separating device described, suspended vby the spring m,

substantially as herein described, and for the purpose set forth.

5. A nail-separatin g device havin g V -shaped grooves, suspended to operative mechanism, which will impart to it a vertical and lateral movement, substantially as herein described, and for the purpose set forth.

6. A nail-separatingdevice havin gV-shaped grooves, to which is imparted a vertical and lateral motion, in combination with moving Weights or other' checking and jarring device, substantially' as herein described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 4th day of September, 1874.

AIsAAo N. BUMBAUGH..
