UNITED STATES PATENT OFFICE GEORGE ALLEN VARREN, OF NORTH BRIDGEVATER, MASSACHUSETTS.

IMPROVEMENT IN JOINERS PLANES.

Specification forming part of Lettcrs Patent No. 1 l l,S90, dated February 14, i871.

To @ZZ whom it may concern:

Be it known that I, GEORGE ALLEN WAR REN, of North Bridgewater, of the county of Plymouth, of the State of Massachusetts, have invented a new and useful Improvement in JoinersA Planes; and 1 do hereby declare the saine to be fully described in the following speciiication and represented in the accompa-- nying drawings, which show the invention ap plied to a plane, termed the Bailey Plane,77 it embracing one or moreimprovements patented by Leonard Bailey.

My invention, or lateral adjuster, as hereinafter described, is to enable a person toeffect a lateral movement of a plane iron or bit in either direction, so as to adjust its cuttingedge in parallelism with the bearing-surface ofthe plane-stock.

Of the said drawings, Figure l denotes a longitudinal section of a plane with myinventiou applied to it. Eig. 2 is an under side view of the plane-iron or cutter, showing its longitudinal slot, which receives the eecentricf the lateral adjuster. Fig. 3 is aside elevation, and Fig. 4 a top View, ofthe eccentric and its operative milled head.

In such drawings, A denotes the plane-stock, and B the cutter or plane-iron, they being represented as provided with mechanism for adjusting the cutter longitudinally, andA for clamping it down to its bed or bearing-surface a.

The lateral adjuster is shown at b as consisting of a disk fixed eccentrieally on a vertical journal, c, which goes through the bed at or near its upper part, and into the shank ci of a milled head, e, the said journal and shank being held in connection by a clamp-screw, f. The eccentric enters the longitudinal slot g of the plane-iron, and hasa diameter equal to the width of the slot. On revolving the eccentric more or less the plane-iron may be moved or tilted laterally either way, so as to bring its cutting-edge into proper adjustment with the bearing or lower surface of the planestock.

The devices for effecting the longitudinal adjustment of the plane-iron consist of a bent lever, C, and a screw, D, arranged and applied to the said iron and the stock in manner as represented, the devices for clamping the iron to the stock being the headed screw E, the slotted lever F, and the eccentric or cammcd lever G, operating against a spring, H, all being as shown, and as commonly made and used in the Bailey plane.

I make 11o claim to anything, arrangement, or combination of devices as set forth and described in the United States Patent,No.67,39S, to Bailey, or in the United States Patent, No. 64,7 90, to Palmer. My mechanism foreffeeting lateral adjustment ofthe bit or planeiron and the application ofsuch mechanism to the bit, or the arrangement of the adjusting mechanism with the slot of the bit and with the stock of the plane diiiers materially from anything represented or described in either of such patents, and is particularly advantageous or clfeetive and simple in construction aud application.

I claiml. Thelateral adjuster, as described, as composed of the disk b, the journal c, the socketed shank d, with its clamp-screw and head, asset forth.

2. The arrangement of the said lateral ad
