'To ALL wit-0M 1T- MAY ooNcnRN:

Be it known that I, WILLIAM WEEKS, of Albany, in tn e county of Albany, and State` of' New York, have invented a new and improved Die for Stamping Wooden Boxes; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being hedto the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical central section of my invention.

Figure 2 is a horizontal section, takenin the plane of the line y y, iig. l.

Similarletters of reference indicate like parts.

rlhe object ot' my invention is to provide a suitable and convenient device for stamping or pressing the inside of a wooden box, and a rabbet on its top edge, for the reception of its cover, by one and the same operation, which object I accomplish by the use of a sleeve and collar and punch with a die, and operated by rods Vand aplunger, ns will be more fully hereinafter described.

A designates e. die, made ot`V iron or steel, or other suitable met-al, and is perforated centrally from its top to its bottom, as shown in section in lig. 1. Said perforation is of three different diameters, as shown in the .same ligure.

At the top of the die, said perforation is made of tho diameter or size of the outside of the required box: F, and of a sufficient depth for the same. Below this first chamber, en 'inner rahbet, a, is formed, of a size suitable to the box which is to be formed within the die A.

From the rabbet a', the central aperture is continued downwards about one and a halt` time, or twice the depth ofthe required. -box F, forming a second chamber, within which the sleeve D is placed, and operated by rods, E, passing through the lower part, end outside el' the shank e of punch B, as shown in iig. 1. g

From the bottom of the sleeve D to the bottom ofthe die A, the centralY aperture is about half an inch in diameter, for the reception of the shank e of'v the punch B. There are also three smaller holes, extending from the bottom oi` the sleeve D to the bottom of the die A, as shown in figs. 1 and 2.

Bdesignates a punch, made of steelor other suitable metal. .The topcf said punch is made of a diameter equal to that of the inside of the required box F, and of any suitable depth, as shown in lig.- 1.

The body, c, of the punch B is made about three-eighths of an inch less in diameter than its top, d, and the shank e of the punch is about half an inch in diameter, and extends below the bottom of the die A, and is furnished with a thread, lf, and nut, y, near its lower end, as shown in lig. 1.

C designates a loose cella-r, or it may be a number of washers, litting snugly to the shank e oi' the punch, and Whose outer diameters are equal te that of the body c of the punch B.

The bottom of the colla-r C rests upon the bottom of the second chamber, or 'middle part ofV the eentra'l aperture running through the die A, as shown in iig. 1.

D designates a loose metal sleeve, litted to slide easily over the head or top, d, of punch'B, and within the middle portion or second chamber of the die A. as shown in iig. l.

The bottom of said sleeve D is perforated, with an opening in its centre equal to the outer diameter of collar C, so as to allow oi an unobstructed and free motion of sleeve D up und down the outside of collar C, and within the chamber in which the sleeve D is placed.

E designates-rods, passing upwards from the bottom of die A tothe bottom o-f the sleeve D, as shown atb i`n lig. 1.' Said rods E maybe operated upon from their bottoms to move upwards against sleeve D, by any suitable nell-ltnown device, such as cams or levers, for producing su'ch motion- F designates a wooden box, showing its position within the die A, after having been pressed down byA plunger G, uponV the tops of punch B and sleeve D.

H designates a nut, upon the lower part of shank e of punch B.

From the above description, it will be seen that the punch D is secured firmly to its place within the die A by means of the'nut H. Also, that the sleeve D is made to slide freelyup and dcwn'within its chamber er socket, within the die A. Also, that the sleeve D is moved upwards bythe rods E. o

The mode @operation ofithis improved die will boos follows:V

A block of Wood, of the right size for therequired box, is placed within the upper part of the die A, the plunger G is made to descend upon it, pressing itdown upon the punch B, thus forming the inside of the box F, and, utilis same t ime,volso pressing the wood down into the rabbet a, formed by 'the top of the sleeve D, in the manner shown in g; l, thus forming the rubbet on the top of the box F, upon which itsicover is fitted, then, by pressure ora. blow upon the bottoms of rods E, the sleeve D is forced upwnrds'carrying with it the perfectlyshaped box 'F to the top of the die A,`where it muy-be thrown out by any suitable mechanism.' Y

This process maybe-repented very rapidly nnd'economcally. Having thus described my inventonand the m'ode of its operation, what I` claim asnew, and'desire to `secure by Letters Potent, is,`

The combination of,sleeve D, rods E, punch B, ond vcollar C wit-h :i die, and plunger, G, constructed substantially asand for the purposes herein shown and described.

WM. WEEKS.
