IMPROVEMENT IN IRON-PLANING MACHINES.

Specification forming part of Letters Patent No. 124,676, dated March 19, 1872.

y To all whom it may concer-n:

Be it known that I, ALEXANDRE GAsrEL, of

' the city and county of Philadelphia and State one side of its center. Fig. 2, Plate 2, is a section taken vertically and transversely through' the machine in the plane indicated by dotted line w a', Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this improvement is to hold the traveling bed-plate of a planer down firmly on its ways and prevent trembling by means of a yoked brace, which is applied to a fixed bar of an anti-friction wheel that works on top of a Ilan ged rack on the bottom of the said 'bedplate, and which is also applied to the shaft of the wheel which engages with said rack, thereby forming, in connection with one side of the frame of the machine, a quadrangular brace,

as will be hereinafterdescribed.

The following description of my invention will enable others skilled in the art to understand it.

In the accompanying. drawing, A A represent the horizontal and parallel ways of the bed-frame, which are grooved and receive tenons formed on the bottom of the bed-plate or table B, as shown in Fig. 2.' To the sides of the bed-frame'. is bolted the upright frame for carrying the slides. D is the vertical slide; E the horizontal slide, moved by ascrew, S.

E is a carrier, which has a slight circularmotion, and b is a pivoted cutter-block, carrying a cutting-tool, a. rlhe parts above described may be constructed in the usual well-known manner. On the bottom of the traveling-bed B a rack-plate, c, is formed, which extends the entire length of this bed, and which is flanged at e and toothed so as to form a rack for receiving the teeth of a spu`r-wheel, N, on a hor izontaltransverse shaft, H. This wheelN receives motion from a driving-shaft, o, acting through the medium of a pinion, n, a large spurwheel f is applied loosely on a fixed horizontal admit of the application to the under side of this shaft H, into a groove, p, formed therein,

of a block, t', which is set up closely to the shaft by means of a bridge-plate and nuts j, thus drawing down the roller or wheel f upon the top of the rack e. The brace h, as well as the bracket g1, are adjustable to regulate the holdl ing-down pressure of the roller f in the first in-l stance, andto compensate for the wearing away of the roller and upper surface of the rack.v

It will be seen from the above description of my invention that I hold the bed-plate B down upon its ways, rst, by the bar g and roller f; and second, by the brace h and `shaft H. I thus make the brace `serve a two-fold purpose -to wit: It assists in holding down the bar g, and it also braces the shaft H of wheel N against vibration.

Having described myinvention, what I claim as new is-' The flange and rack e, dependent from the bed-plate By, and the roller f, and the bar g, in combination withthe brace h and shaft H of the wheel N, substantially as described.

ALEXANDRE GASTEL.
