MACHINE FoR MAKING Hoes.I

SPECIFICATION forming part f Letters Patent No. 295,903, dated April l, 138%.

Application filed June 13,l 1883. (No modeLl To all whom it may concern:

Be it known that I, RICHARD E, BREED, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Making I-Ioes; and I do` declare the .following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the'accompanying drawings, and to the letters and iigures of reference marked thereon, which form a part of this specification.

Thisinvention relates to improvements in the hoemachine for which Letters Patent No. 280,287` were granted to me June 26, 1883, the object being to provide effective means for preventing the displacement and consequent malformation of the hoe-blank under the pressure of the forming devices.

In the annexed drawings, illustrating the invention, Figure l is a sectional side elevation of a portion of a hoe-machine embodying my improvements, the mandrel being shown in a raised position and thrown back against t-he folder. Fig. 2 is a sectionalplan of Fig. l, Fig. 3 is a sectional side elevation, showing the mandrel lowered and thrown forward. Fig. 4 shows a plan View of a sliding guideframe and top view of a folding device. Fig. 5 is an end view o'f the guide-frame, showing the hoe-blank indotted lines; and Fig. 6 is a perspective view of one arm of the guideframe. i

Like letters indicate like parts.

A represents the bed-piece or table of the machine.

B is a bar, pivoted at c by means of an'elongated slot, b, in the end of said bar, which passes around a pivot or pin, c. The bar B is supported near its forward end bya spring, C, and on its upper side Vit carries a lug or projection, d, back of which is pivoted a mandrel, D. The mandrel D is provided with a spring, c, by which it is supported in such a manner as to have an elastic movement upon its pivot. The bar B is passed beneath or through a yoke, E, to which it is connected by a spring, f. The forward end of the piv oted bar B is slotted at g, and carries within said slot a friction-roller, lz, that bears on the forward surface of a lock, catch, or tumbler, F, that is pivoted to a standard, G. The tumbler F engages with a latch, H, that is pivoted to a lug, z', beneath the table. The bar B is provided with a rod, 7c, that passes through an opening in` the bed or table A,

y beneath the slide-frame of the machine.

I is the shank or socket folder. The trunnion-plate K and the slideframe L are represented by dotted lines in Figs. l

`and 3.

slide-frame L, by resting on the upper end of i the rod 7c, depresses the bar B and holds the mandrel away from the face of the folder. After thehoe-blank has been placed in position, with its shank portion resting in the folder back of the mandrel and its blade supported bythe truunion-plate, the slide-frame will be thrown back against said blade. the slide-frame releases the rod k and bar B, and enables the roller h to travel upon the curved anterior surface of the tumbler F. The upper rear part of the tumbler F is `notched or otherwise fitted to the end of the latch II, so that said latch and tumbler, while in engagement,will hold the bar B against the tension of the spring f until the pressure of the bar against the latch raises the latter, either into one of theuppernotches ofthe tumbler or onto the top of the same, when the spring f will throw the barB back into the position shown in Fig. l, thus carrying the mandrel back into close connection with the folder. This vibratory and sliding movement of the bar B actuates the mandrel D in such a manner as to obviate the liability of displacing the hoeblank as the mandrel takes its position within the folder'. were pivoted so as to have simply a vibratory movement, the mandrel would exert such frictional pressure against the lower edge of the folder and the shank end of the blank as to throw the blank out of position. The blank This movement of l It is obvious that if the bar B IOO and provided with a spring, c, as shown, is

.by anyT convenient means.

being now in position, and the mandrel being in its proper place in front of the shank-folder, the trunnion-plate and slide-frame are thrown down upon the table, thereby forming the hoe, the shank-folder being actuated from thetrun- Dion-plate, as described in my said patent, or The slide-frame in its downward movement strikes the end of the rod 7c and depresses the bar B, whose roller h travels down the face of the tumbler F. After the center of said roller passes the point upon which the tumbler is pivoted, it forces in the lower end of the tumbler, thereby throwing its upper end forward, so that the latchH falls into its former position, as shown in Fig. 3. The forward and downward movement of the bar B at the same time compresses the spring f for future action aud disengages the mandrel from the hoe-socket.

The mandrel D, being pivoted to the barB,

enabled to accommodate itself to the socket in its downward movement, and becomes disengaged therefrom without liability of distortin g said socket.

Beneath the table A, supported in bearings mm, is a guide-frame, M, carrying at the forward end of each arm a head, N. on which is formed or attached a plate, n. On each arm of the guide-frame is a spiral spring, o, one end of which bears against one of the rear bearings, m, while the other end is attached to said arm, or bears against a pin, p, that is passed through the same.

. Instead of arranging the springs O as shown, they may be ar-ranged in any other convenient manner, the object being to hold the heads N of the guide-frame close against the face of the folder. The form of the head N is shown in Figs. 5 and 6. A tapering groove, s, is formed in the inner or opposing face of each head, which is beveled to correspond with the inclined sides of the shank portion of the hoeblank, while the bottoms of the grooves are parallel, as shown by dotted lines in Fig. 5. The shank portion of the hoe-blank is inserted into the grooved faces of these heads N N, and is passed down until it reaches the lower ends of the grooves s s, or until the wide end of the shank passes fully into the shallow end of each groove, when the blank will fall back, so thatits shank can rest against the knuckles of the folder, with its edges supported by the guide-plates a n on the grooved heads of the guide-frame. When the trunnion-plate K and slide-frame L are thrown down upon the table,the blade ofthe blank held between them is folded over at an angle with the shank or socket portion of the hoe, which is folded around the mandrel D by the socketfolder I, that is actuated by any convenient means. As the folder I closes, the guide-frame M is gradually pushed forward or toward the front end of the machine against the pressure of the springs O O, which hold the heads N N rmly against the folder during the movements ofthe parts. rlhe shank portion of the blank being held back centrally against the knuckles of the folder by the mandrel D, its edges, which lie on the guide-plates a n, will b'e drawn evenly forward by the latter, and caused to approach the mandrel uniformly from each side and out of the way of the folder until the latter eXpels the heads N N of the guideframe and closes firmly around said shank, so as to impart thereto a form corresponding to that of said mandrel and of the inner face of said folder. The shank portion of the blank is thus under the control of the sliding guide-frame until all liability of malformation ispassed. After the shank or socket of the hoe is thus fully formed, the mandrel D is disengaged therefrom by the pressure of f the slide-frame L on the rod 7c acting through the pivoted bar B, as before described.

The completed hoe may be removedv from the machine by throwing back the trunnionplate K, which at the same time actuates appropriate"mechanism, as described in my former patent, for opening the folder I, so that the hoecan be taken out anda new blank inserted. As the folder I is thus opened, the sliding guideframe M, under the pressure of its springs, moves into its former position, with its heads N N resting against the inner face of said folder for further operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl. The combination, with the slotted bar B, pivoted by means of an elongated slot, b, engaging pin c, of the tumbler F, latch H, and spring f, whereby a vibratory and sliding movement may be imparted to said bar, substantially as described.

2. The combination, with the bar B, pivoted by means of an elongated slot, b, and having a Vslotted end, g, carrying a roller, h, of the pivoted tumbler F, latch H, and spring f, whereby said bar is capable of a vibratory and sliding movement, substantially as described.

3. The combination, with the folder G, of a mandrel, D, pivoted to a bar, B, having a vibratory and sliding movement, substantially as described.
