SPECIFICATIONformn'g part of Letters Patent No. 251,961, dated January e, 188e.
Application inea october 24, 1881. (No modem'4 To all whom `it may concern Y 'Be it known that we,JOHN SMITH and FER DINAND STEINKE, of Horicon, in the county of Dodge and -State of Wisconsin, `have invented certain Improvements in Gultivators, of which the following is a specification.
Our invention relates to afriction device for lholding cultivator teeth or shovels in an operative position until subjected to an excessive strain, and then permitting them to yield and swing back toprevent breakage or injury.
The invention consists in an annulus or bandi` formedupon or secured to the shovel-standa rd, arranged to encircle a stationary hub or boss secured to the beam or drag-bar, and provided with a tightening or clamping device, or attached to a'stationary block and arranged to encircle a hub or boss formed on the 'shovelstandard. g
The invention further consists in means hereinafter described for attaching the shovel or tooth to the standard.
In the accompanying drawings, Figure 1 represents a side elevation of our device in its preferred form,the beam or dra g-bar broken away to show the parts; Fig. 2, a view of the parts separated one from another; Figs. 3, 4, 5, and 6, views showing slightly modified forms of the same.` y A The essential feature of this invention, so far as relates to thefriction device, consists in the employment ot' a circular hub or boss and an encircling annulus or band provided with devices forl tightening it upon the hub or boss, one of said parts being permanentlyv fixed in position and the other arranged to move or swing about or upon the hub as a center of motion.
Referring to the drawings,A represents the shovelstandard; B, the beam or drag-bar by which it is carried; C, the hub or boss, and D the encircling band or annulus by which the necessary friction isproduced.
In Fig. 1 the hub or boss C consists merely of a dat circular disk, and the annulus or encircling band D is formed directly up'on and integral'with the shovel-standard A. The annulus is passed about the disk or boss'C, and the two are then passed upward into a slot, a, eX- tending vertically through the beam or dragbar B. When in proper position the disk or boss is secured in place and held against rotation by two bolts, b, passing transversely through thedisk and through the beam or dragbar, as shown. i
The annulus or band D is divided or open at 011e side and furnished with ears c, through which a clamping or binding bolt passes, the annulus being slightly smaller in its interior than the exterior of the disk, so that when the ears c are drawn together by the bolt the annulus or band is caused to bindupon the disk with any desired degree of friction, according to the extent to which the bolt is tightened.
The degree offriction is regulated, so that the standard and the shovel which it carries shall remain fixed or stationary in their working position until someobstruction is met with oftering a resistance which would be suici'ent "to injure the shovel or standard or other part of the machine unless the standard he allowed to yield.
tion is overcome and the Standard and shovel are permitted to swing back, the disk C serving as a pivot or"centerl of motion.
In Figs. 3 and 4 a slightly-modified form of the annulus and boss or block is shown, by which a double frictionlsurf'ace is obtained. In this instance thel boss or block G, instead ot' being in the shape of a circular disk, is of the form represented in Figs. 3 and 4, having lateral perforated anges c, by which to secure it to the beam or drag-bar, a segmental grooved portion, f, around which the annulus or band D passes, and an internal semicircular seat, g, to receive the circular head 71. of the standard A, which head serves as the pivot or center ot' Inotion upon which the standard swings. The friction band or annulus j C is in this case formed of a piece ot' metal rod or bar-iron bent ends passed through lugs or ears t', formed on the standard A, and held by nuts j, which serve also to produce the required degree of friction between the band D and its groove 7c and between the head h ot' the standard and its seat g.
Figs. 5 and 6 show another slight modication of the friction device, the hub or boss C being formed upon the standard A and the friction-band D being wound around the boss and having its ends passed through the flanges of a metal block or plate, E, which covers the around the segmental portion f, and having itsV When this point is reached the frie- IOO beam to retain the standard in place. In this as in the preceding form the friction of the band is increased or diminished by adjusting the nuts n placed upon its ends. The standard is in each case formed with an enlargement or ears, 0, near its lower end, through which are two slots or holes, p, from front to rear, and with lips or ears q near its upper end. Each tooth or point F is made reversible, so that either a narrow point or a broad shovel may be brought into use by simply turning one or the other end down into a working' position, the shank 1^ of each tooth resting against the front face of its standard, and the uppermost point of the tooth being passed between the lips or ears q, as shown. When in this position the shank is rml y secured by a metal strap or clasp, G, passing across the front and around the sides of the shank r and through the holes or slots p.
The rear ends of the metal strap G are provided with inclined notches s, into or through which a pin or bolt, t, is passed, as shown, and between the pin or the bolt and the rear face of the standard is inserted a wedge, u, by which the strap is drawn firmly against the shank of the shovel-point, and the latter is secured rigidly in position.
We are aware that friction devices adapted to hold shovel-standards at any desired angle and with any desired degree of firmness have been made in a variety of forms; but we are not aware that any one has hitherto provided an encirclingband capable ofcontraction upon a hub or boss to produce the desired amount of friction, one ot' said parts being fixed and the other movable relatively to each other.
We are also aware that straps and wedges have been employed to secure'shovel-points to 45 their standards, and we make no broad claim thereto.
4 Having thus described our invention, what we claim is l. The combination,in acultivator, of a beam 5o or drag-bar, a shovel-standard, a hub or boss, and an encircling annulus or band adapted to be contracted upon the boss, the boss and annulus being attached, one to the beam and the other to the standard, substantially as and for the purpose set forth.
2. In a friction device for cultivator-standards, the combination ot' a hub or boss and an encircling annulus or band provided with a clamping device, substantially as shown, one 6o of said parts being stationary relatively tothe other. y
3. Thestandard A, having at its upper end the annulus or band D, open at one side, and provided with a bolt, whereby it may be contracted, substantially as set forth.
4. The shovelstandard A, provided with lips q and openings or holes p, substantially as and for the purpose set forth.
5. In a cultivator, the combination ot a shov- 7o i el-standard, A', provided with slots or openings p and lips q, a shovel point or tooth, F, a strap or band, G, passing around the shank of the tooth and through the slots, and means, substantially as described, for tightening the strap 7 5 or band.
6. In combination with the standard A, provided with openingsp, a shovel point or tooth, and a strap or band, G, adapted to straddle the tooth-shank and to pass through said open- 8o ings, and notched as described, a pinor bolt, t, and wedge u, all combined and operating as set forth.
