' Specification of Letters Patent.
Patented Jan. 14, 1908.-
Application filed June 28. 1907. Serial No. 381-245- for sharpening plow shares, harrow disks,
and the like, and for rolling out plates and training shoes; and the invention conslsts in certain novel construct1ons and combinations of parts as will be hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation of a machine embodying my invention, the swinging carrier for the work holder being shown raised in dotted lines. Fig. 2 is a top plan view of the machine. Fig. 3 is a front elevation of the machine looking at the rollers, the work holder being broken away. F ig. 4 is a detailperspective viewillustrating the swinging carrier and work holder, together with the frame bars to which the swinging carrier is pivoted. Fig. 5 is a perspective view of the bearing frame for the adjustable roller, showing the same in con nection .with the eccentric and the shaft therefor, whereby the said bearing frame may be raised and lowered, and Fig. 6 is a detail view illustrating the bearing for the lower shaft.
In the construction shown, I support the several parts on the bed plate A having'barings B, in which is journaled the drive shaft 0 provided with tight and loose pulley'sat D, and also having .a pinion E which meshes with a gear F on a roller shaft G, preferably the lower stationary roller H as shown. This shaft G has a pinion I which meshes with a pinion J on a rollershaft K of the roller L, the latter'being adjustable toward and from the roller H by the means presently described.
The shaft Kis loosely mounted at its rear erid in a bearing M, while its front end is mounted in a bearing N in the up or end of the bearing frame 0, which bearing frame may be raised and lowered by the means presently described to adjust the roller L toward and-from the roller H as may be desired in the operation of the invention.
In the construction shown, the bearing frame 0 is provided at its lower end with a dependin portion 1 having a circular hearing in whlch fits an eccentric 2 on a shaft 3 journaled to the frame, and this shaft may be turned to operate by its eccentric to raise and lower the bearing frame.
turned, and a pawl 5 supported on the main frame and engaging with notches or serrations 6 operates to hold the shaft in any desired adjustment. By this means, the bearing frame 0 may be raised and lowered as desired.
In the construction shown, the bearing frame 0 is provided with side bars 7 which extend from its lower portion 1 upwardly on opposite sides of the rollers L and H, and support at their upper ends the bearing for the upper roller L, as best shown in Fig. 3 of the drawings.
The main frame is provided with bars 8 which project upwardly along the opposite sides of the roller shafts, to a point above the upper shaft, and afford a pivotal support at 9 for the swinging carrier P for the work holder. This carrier P is made in sections 10 and 11, adjustable longitudinally relative to each other, and arranged to be securedin different adjustments by the nut 12, turning on a screw 13 to bind the sections together,
as will be understood from Fig. 4 of the drawings. The front section 11 is provided with a depending portion 14, to which is pivoted the work holder 15. This holder 15 is pivoted at its upperend to the de ending portion of the carrier, is rovided with the outwardfy projecting arm 16, on which the weight 17 may be secured so it can elow its pivot.
The I shaft has a handle 4 by which it may be be adjustable along the arm, it may be by threading the arm and screwing the weight thereon as shown, and below this arm the work holder supports the work. Manifestly, the work may be adapted for the articular kind of .work it is designedto ho d. That shown is adapted to receive harrow disks, and its end is threaded, and the harrow disk isslipped us over the threaded portion of the work ho der and a nut 18 is screwed on the work holder up against the harrow'disk pressing the same againsta shoulder provided for the purpose, as shown. The lever arm with the weight 17- operates automatically to hold the work to the rolls or dies between which the work is held in the operation of the machine. Manifestly, these dies maybe varied and different sets applied for different classes of work.
A spring Q operating between the front bearings o the fixed and movable roll shafts,
is arranged to spread the rollers or dies when' 7 is turned by its raising of its lever.
I and provided with a roll or -In the operation of the'machine, motion is given to the shafts and the rolls or dies thereon by the gearing before described, and' by means of t e eccentric operating upon the bearing frame I am enabled to ad ust the pressure on the dies instantly to any desired de ee. I
claim: I
1. A machine substantially as herein described, comprising a main frame, adrive shaft, a roller shaft geared with the drive shaft, and having a pinion, a roll or die'on said shaft, a second roller shaft having a pinion meshing with that of the first said shaft, die cooperating with that on the first shaft, a bearing for the rear end of the second shaft, a bearin frame having at its upper end a bearing or the front end of the second shaft, said bearing frame having side bars'extending down on opposite sides of the shafts, and provided at its lower end with a portion having an opening for an eccentric, an eccentric 1n said openmg, and means for t the. eccentric wherebly; the operation of theeccentric will move t e movable die toward and from its mate.
2. A machine substantially as described,
comprising a main frame,'opposing rolls and their shafts, a work holder, a carrier supporting said holder at one end, and frame bars secured to the main frame and rojecting upwardly along the opposite si es of the roll shafts, and afford apivotal support at their u er ends foi' tie swinging carrier, substantia y as set forth.
3. The combination with a main frame, and the roll shafts, of a swinging carrier pivoted at one end to the. frame, and a work holder having a pivotal connection with the other section of the carrier and adapted to support the work to be operated upon, and a weighted arm in connectlon with said work holder, whereby to hold the work to the rolls or dies, substantially as set forth.
4. The combination of the main frame having bearings for a roller shaft, a roller shaft journaled in said bearings, a second roller shaft-operating with said first shaft,
bars extendlng from the main frame up wardly on opposite-sides of the said shafts, a swinging carrier pivoted at one end to the upperends of said bars, and work holding devices sup orted by said swinging carrier, substantla 1y as set forth. DAVID HARRISON SN EED.
