Specification of Letters Patent No. 27,986, dated April 24, 1850.

following is aV full, clear, and exact descrip lion of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specilication, Figure l, as thereon marked, being a perspective or side view showing the improvements and representing the frame of the said American Eagle sash and molding machine, with the improvements marked thereon which the said VILLIAM D. JONES claims to have added and attached thereto and which as thus improved he claims to be his invention, said improvements being as follows, to wit: lst, the edge working apparatus, being the two upright shafts marked A and 2LB, Fig. l, and the manner in which the same are attached to wit: d is attached by means of a box let into the lower part of the upper timber M oie and a half inches from the face of the same.v and a step marked l, on the upper side of the lower timber of the frame, marked N." The head H containing the bits marked timber BLW-by means of an opening, cut cross-wise through the upper face of said timber to the depth of two inches, and of sutlicient width to allow said head with the bits therein as above described to revolve without obstruction.

The shaft B is attached to the iron slide frame C, on the lower side of the horizontal part of said frame marked U, by means of a cast box on the under side of said O. and at the lower end of the said shaft B is attached by means of the step l, cast on the lower end of said iron frame C. The above described O being the horizontal part'of the iron frame C, is dovetailed into the lower side of the bed plate L, and is adjusted to suit the size of the lumber to be worked, by means of sliding out or in, the said O being secured to the bed plate L by means of the iron bolts marked D, D, which pass through said L and O, there being slots in plate Gr, G, is sunk in the upper part of theA t) as represented in Fig. 2 7 by the letters l, i," which said slots allow the said t) i to sli-de in and out as above described. rEhe lower end of said iron plate C, is secured bv the brace marked 3, 12, in Vig. l. which is bolted by 'the iron bolts marked QQ i Q, to the upright timber .i. said brace being also bolted, bythe iron boit r', to the lower part of the iron slide frame C, with a slot in said frame 1" C. represented by the two parallel ink lines running inward from said bolt S So as to allow said bolts to passl through it as the frame slides in and ont. in adjusting it. as' aiiorcsaid to suit the size. of the timber to be worked.

I e shafts f and B are adjusted to suit the size of the timber to be worked by raising or lowering the same by means of the set screws marked J, J.

The heads ll, H, containingthe bit-s VfG, G, and E F, are solid in 'the shafts. the said bits being' dovetailed into the heads li. and fastened by means of a set screw, earh bit being but one piece; and each bit having a slot in the back end of the same to straddle the said set screws.

The horizontal shaft T drives the upright shaft ,A, by means of a ball or oval piillej; nairked K, over which the belt if passes, connecting said shafts as shown in Fig. l. lhe said pulley K is made oval it is not in a direct line with the shaft lt would, therefore, be impossible to run said shaft A with a straight pulley at "ii K. The pulley V is a long straight pulley. and is used by the belt W to run The pulley X, gets its power from a pulley on the American Eagle machine 7 above alluded to and being at the right. end of said i American Eagle A 7.* r i v 1 sash and molding machine. lhe several de tached parts represented more fully in the drawing marked Amended drawing, and

V`in "Fig, Q thereof, are the specific improvements which l claim to have made on the aforesaid American Eagle sash and molding machine -being as follows to wit:

The shafts marked B, and 'I, with the heads 11, H, and the bits in said heads marked lif Ff and G, i G, also the set screws in said shafts A and l, marked L J, also the ball or oval pulley K, and pulleys V and X, also the the iron slide frame C, together Awith horizontal part thereof marked O,

and the slots therein marked P, P, and Z,"` also the step L on the iron slide frame C, also the grace marked 12, 15, with the bolts in the saine at Q, Q," and S, also the slot marked Y in the bed plate L. The Slot Z, in the detached iron sliding frame C .in said Fig. 2, of amended drawing and also the said slot Y, in the detached iron bed plate i L, in Same drawing and figure, are the openings in which the head H on shaft- B revolves as Shown in Fig. '1 of said amended drawing. The above Several partis of machinery and improvements, as set forth and shown 1n 191g. 2 ot said amended drawing,

parte of the machine to which they are con-V nected, the two first named Shafts bein susceptible of both vertical and lateral adjustment as herein set forth.
