Beit known that I, VVILLIVAM- ORD, of

Brooklyn, in the county oi' Cuyahoga and State have invented certain new and useoi Ohio of which the ful Improvements in Gultivators, following is a speeication.

My improvements relate tothe construction of ,iron cultiva-tors, and have for their object lthe production of a cheap, simple,`and durablemachine, whereby the farmer or user is enabled to easily and readily construct or repair his own cultivators. Th ese improvements consist in providing peculiarly constructed and i and in proper positions,

`ready adjustment of the adjusting parts when required.

appliedV clamps for attaching the teeth, brackets, and braces to the frame-work, whereby the parts are held more firmly and rigidlytogether In the accompanying drawings, Figure l is a top or plan view, Fig. 2 is a side elevation,

`and Fig. 3 is a rear elevation, of my improved a clamp adapted for securing a curved springl j cultivator-tooth. My said clamps are thus usual way.

nently attached to said central bar, near its made applicable for either form or kind of cultivator-teeth. Y

A in the several gures is the main or central bar, to which are attachedtwo side wingbars, B B, by a joint near the front end, in the Handle-bars C O are also permafront end, and are supported by a U-shaped support. This support provides two perpendicular arms for the brace-adjusting block to slide perpendicularly upon in expanding or.

contracting the wings. The rear ends ofsaid wings B B are connected to the central bar by y extension-arms D D in the usual way. Said bars B D are adj ustably secured to the central bar by one of my improved clamps. Said clamp consists of a lower block, b, having a longitudinal groove fitting on the under side of the bar A, and with a transverse space, for

and which allow y the extension-bars D D to lie in, beneath said bar A, `as seen in Fig. 4. Said blockl is of castiron, and has two bolts, d d, in two corners, di-

agonally across from each other. Above saidA block bis placed a grooved plate or cap, b2, fitting over the top edge of said bar A, and

has two holes for the said bolts old to pass up through, and is secured by two nuts on top. The. position of the two bolts and the arrangement of this clamp are such as to secure aiirm hold on the bar and prevent its working loose and rocking. The U-sha'ped support is also secured by the rear nut and bolt of this clamp.

The corner-clamps on the rear ends of the wing-bars B B are similar to this, but are provided with a central pin, i, over which the end of the extension-bar D sits, and said lower block is cast with the bracket, while the cap or top plate has a downward projection, b3,

which rests on the top of the bar D, and itg also has on the upper side an ear, e, to which is pivoted a brace-rod, E. Said brace-rod is simplyV joined to the clamp aforesaid, and has its upper end curved and bent and provided with a small grooved block, F, having a hole, and tted onto the bent end of said rod, which end is also screw-threaded and provided with athuInb-nut, f.- This block F ts onto the perpendicular arm of the U-shaped handlesupport, the bent part ofthe rod formsa bearingagainst the side of said arm, resting in one of the notches in the support, and when the thumb-nut is screwed down the rod is firmly held in place. This rod and its clamp form an adjustable side brace for securing the wingbars in their relative position to the main or central bar, and is very simple and easily operated. l

In Fig. 6 is'shown a clamp-block adaptedto hold curved spring-teeth. The under side of this block is provided with a recess and .two lugs, l Z, having/a groove inline with the sides of said recess. The end of the tooth is made a little wider at the-end to give its sides a little taper, said recess also being wider at the front end. The purpose of this is to enable the tooth tc be inserted and removed whenl desired. A screw, S, is put through a slot in the tooth for securing it to the block.I The slot enables the tooth to be adjusted bach in case of wear or becoming loose. Y By removing said screw the tooth is easily removed, as

I OG

`Wm be seen by dotted limitingl e, which is done bypushing the tooth forward until the narrow part comes between the lugs. Then the tooth may be taken out by raising one side and withdrawing vit from the opposite lug.

Among the advantages and the objects of my improvements are to dispense with the large number of holes that are required yto be drilled in the bars `in the present method of constructingiron .cultivators, which considerably weakens the bars, and requires much time and labor to perform. With the use of my improved clamps'the time, labor, and eX- pense of constructing, changing, Aand repairing is greatly reduced, and enables an ordinary blacksmith or farmer to do the work himself. These clamps are complete and ready for cultivator-plows. It will be seen that the teeth or brackets may y be adjusted to give them more or less pitch forward or back, as the bottom ofthe groove in the blocks bis made curved or crowning, so .that by loosening on one nut and tightening up on the other any required pitch may be obtained.

Having described myinvention, I claim as follows:

l. In combination with the side bar, B, and

brace D, the clamp herein described, consist-y ing of the part b, having longitudinal groove to receive said bar B, transverse space to receive the brace, and lug i, which is received into an aperture in said brace, and the capplate b2, having downwardly-extending 111g b3, and the securing-bolts, as and. for the purposes set forth.` Y

2. 4ln combination with the frame U, handles C O, and central bar, A, the clamp b b2, the latter having the ears e, the arm E, block F, having slot to receive the standard of the said frame U, and set-screw f, for giving any desired adjustment to the side wings,'as set forth.

VILLIAM ORD.
