METAL-PLANING MACHINE.

SPECIFICATION fermmg part 'or` Letters Patent No. 293,289, dated February 12, lese.Y

' .application filed september 21, Issa. (No model.)

To a/ZZ whom it may concern;

Be it known that we, EDWARD P. VALTER and HENRY C. WALTER, citizens of the United States, residing at Bridgeport,'in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Metal-Planting Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to certain novel and usefull improvements in machines for planing metal, and has for its object to impart motion from the driving -pulleys to the mechanism which effects the movements of the table by positive and uniform means, While at the same time the arrangement of the pulleys maybe more convenient, and all unnecessary rattling noise common to planers done away with; and with these ends inview our invention consists in the construction and combination of elements hereinafter fully and in detail explained, and then specically designated by the claim. i

In order that those skilled in the art to Which our invention appertains may more fully understand its construction and operation, we will proceed to describe the same in detail, referring by letters to the acccompanying drawings, forming a part of this specification, in whichi Figure 1 is a plan View, illustrating our improvement applied to a planer, such as is described in Patent No. 36,113, granted August 5, 1862, to William Sellers; andA Fig. 2 a front elevation of the same.

Similar letters denote like parts in both gures'of the drawings.

We will not enter into any description of the principles of` construction and the opera tion of the machine proper, as this forms no part of our invention, and, moreover,'is the same as in the patent above referred to. As

'is set forth in said patent, motion is communia rack in the table. This shaft we extend out ward at the side of the machine, and arrange on the extremity thereof a spur-wheel, C,`

which gears with a spiral pinion, D, on the "shaft E. This shaft is j ournaled so as to extend transversely to the li-ne of movement of the table..

The driving-pulleys may be arranged on any convenient portion of the shaft E, either on the same side of the machine, or one at each side, as desired.

The operation of our improvement is as follows: The shaft E receives motion from the pulleys and causes the spiral pinion D to gear with the spur-Wheel C and operate the shaft B. The actuating of the shaft B by this means produces a result never before accomplishednamely, a uniform positive movement of the table without any rattling Whatever. We preferably arrange the shaft E at right angles to the line of movement of the table, whereby Weare enabled to keep the pitch of the teeth in the spur-wheel C and the angle of the helix on th e spiral pinion D in a plane parallel with the shaft B, which of course is a great ad'- vantage. When the movement of the table is reversed there is no shock because the helix on the spiral pinion always maintains a firm as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
