IMPROVEMENT IN |"HE MA'NUFACTURL'OF HOE-BLANKS.

Specification forming part of Letters Patent No. 521, dated February 25, 18-61 Reissue' No. lylsl, dated May 26, 1863.-

T o all whom it may concernef Be it known that I, NATHAN BRAND, o Leonardsvllle, Madison county, and State of New York, have invented certain new and `useful Improvements in4 Machinery for Making Hoes; and I do hereby declare that the same are described and representedin the following specification and drawings.

Prior to my invention what are termed goose-neck hoes, with solid shanks formed `of the same piece of metal with the hoe-plate,

were made by plat-ing the blanks wit-h a ham- 4 mer, or partly by hammering and partly by by rolling it in dierent directions with rollers provided with scores'to leave the shank and plate about the shank in the. proper forni and of the proper thickness, while the plate cf the hoe is reduced as thin as may he required. Hence the nature of my invention consists in a machine provided with a pair of vibrating reciprocating dies or rollers provided with a longitudinal score parallel with the axis on which the rollers vibrate, and in combining with these dies having a longitudinal score a pair of vibrating reciprocating dieser rollers provided with a lateral or circumferential score for .the shank of the hoe, the first-mentioned dies being arranged to roll the blank and elongate it at a right angle to the shank,

and the second to elongate the blank parallel' with the shank and at a right angle to the first elongation.

To enable others skilled in the art to make and use the improvements which I have inl vented, I will proceed to describe their construction and operation, referring to the aceompanying drawings, -inwhich the same letters indicate like parts in each of the figuresD Figure 1 is a plan or top view of a machine withmy improvements. Fig. 2 is an elevation of oneside of the machine, and Fig. 3 an elevation of one end.

1n the above-mentioned,drawings, A A are side sills connected by the bars B B, making a strong frame, to which the standards O C are fastened a proper distance apart to receive the boxes D D for the journals of the rollers E E',

which may be made in the form shown in the.

drawings.' f Thefroller E is provided with a crank, F, connected by the link G to the crank H 011 the v'shaft I, which turns in boxes t. fastened to the sillsA A, and may be provided surfaces in unison whenv they are operated.4

The crank F should be one-fourth longer than the crank H, or so proportioned that one revolution of H will turn the rollers one-third the way around `aud back' again. The four'standards C C are connected at the top .by the bar K, which is firmly fastened totheni. To force the roller E down on the hoe-blank after it is pnt between the rollers, l make female screws in the bar K, right over the boxes D D, and tit the male screws L L to turn in the bar, to which screws the gears M M are fastened and connected to each other by the stud-gear N, 1

which turns on the stud 1 in the bar K, as shown in Figs. 1 and 3.

The crank or lever Q is fastened to the gear M to enable the workman to turn the screws 'L L with one hand and close the rollers orV dies on the hoe-blank while he holds it between said rollers or dies with the other hand.

The rollers .or dies which are rst applied to the hoe-blank project beyond the standardsC at the left-hand in Fig. 3, and the roller E has a longitudinal'groove or score, R, in it parallel with the axis of the roller, in which score the extension of the shank onto the hoe-plate is formed as the blank is elongated by these rollers at a right angle to its shank.

Opposite to the scoreRthere are two prongs fastened in the end of the crank F, forming the forked guide S. Into this the shank of the hoe-blank is placed when the blank is pnt between the rollers.

The faced dies T T are arrangcd'upon the rollers centrallygbetween the standards to roll the hoe-blank and elongate it parallel-with the shank, and the lower roller, T, has a groove or score, V, in itv running a short -distance npon it, to form the extension of A:the shank onto' the plate 'of the hoe. This score V runs circumferentially on the die or roller at a' right angle to its axis,as shown in Fig. 3.

^ There are some grooves a a in the standards C, for the ends o f the bar b to traverse in,.` which bar b has two rods or links, d d, fastened to it, to connect it to the eyes f f in the roller E, so that as the roller is rocked or vibrated the bar b is traversed to .correspond very nearly with the surface of theroller, and carries the notched guide c with it, into which guide the shank ofthe hoe-blank is placed when it (the blank) is tobe acted on by the rollers to elongate it parallel with the shank, and spread-the blank to make it as thin and as large asit may be required.

The hoe-blank, Fig. 4, is prepared in a manner well known and practiced by hoe-makers,

and properly heated and placed between the ends of the vrollers with the shank in the forked guide S, with one hand, and held there and rolled, while the other hand seizes the crank Q and turns the screw L and closes the rollers on the blank, and when it has been suiciently elongated at a-right angleto its shank, as shown in Fig. 5, .and while it is still hot, the screw is -turned back Aand the blank taken out and placed between the diesT T,

'l with the shankin the notched guide c, and held there while the screws L L are-turned and the blank elongated parallel with the shank, and rolled to Vmake it as large and as thin as h required, when it may be taken t9 the shears and cut the size required.

From the above description it is Aapparent that the blanky is rolled rst at a right angle to the shank and then parallel with it until it is as thiaand as large as shown in Fig. 6.v The dies may be filed oli' about or around the scores R and V, .to make the plate of the hoe gradually thicker and sti'er as it approaches the-shank. Y

I contemplate that a lever may be hinged to the forked guide S, and also to the traversing guide c, and that there maybe a score in' the upper die or roller, and that my machine `will answer to plate trowels and some other articles.

The advantage of my machine overtrip-hammers for plating hoes maybe enumerated as follows, to wit: Two men with my machine and two tires can plate as many hoes in a day Y as twelve men and six trip-hammers with six iires; and my machine only requresas much power as one trip-hammer; hence'the labor of 4 ten men, Vthe coal forfour fires, and the power required for five trip-hammers are saved, and

the hoes plated bythe machine are finished with one-third of the labor required t'o finish those plated with the hammers; and, besides, the rolled hoes are better than the hammered, as the metal is -paeked and plated more uni- V formly; and, further, the rolled hoes are made with two ounces less of metal than the hammered hoes, and steel that will not answer to make hoes by hammering will make good hoes when rolled with my machine. .y

I believe I have described and reprented the improvements in machines lfor making hoes which I have inventedx'so as to enable any person skilled in the artlto make and use Vthem withoutfurther invention or experiment.v I will now state what I desire to secure by Letters Patent, to wit:

Y 1. The vibrating reciprocating rollerdiesE E', constructed and operated as described, for the purpose set forth.

f 2. In combination with the dies E E', having a longitudinal score, apair of vibrating recip -rocating dies or rollers or circumferential score for the shank of the provided with a lateral hoe-blank, so asto roll'the hoe.blank and elongate it parallel with the shank.

Y NATHAN BRAND.
