KNOGKDOWN FORGE.

Application filed June 1'7, 1915.

To all whom it may concern:

Be it known that l, HENRY B. Knrrnn,

a citizen of the United States, residing'at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Knockdown Forges; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to blowers and forges and more particularly to foldable legs for portable knock-down forges.

The primary object of the invention is to provide in a portable knock-down forge improved means for folding and locking the legs of the forge in either folded position, or in position for use, so that the apparatus can be folded into compact form for convenience in packing, shipping and transporting the same from place to place.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which form a part of this specification, and then pointed out in the claims at the end of the description.

In said drawings, Figure 1 represents a perspective view of a portable forge mounted upon foldable legs embodying my invention;

Fig. 2 is a vertical sectional elevation of the same; parts of the forge being broken away and the foldable legs being shown in different positions in full and dotted lines; and

Fig. 3 is an enlarged detail perspective view of a broken-away portion of one of the legs and the bracket to which it is secured detached from the forge body or frame.

Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the letter A may denote the forge body or frame of what is known as an Army and Navy folding forge, which may be of the form shown, or of any desired construction, and as my present invention pertains solely to the foldable legs and means thereon for ad justably securing and locking the same to the forge body or frame in upright or folded position, further description of the forge proper is unnecessary. In the form shown the forge is mounted. upon four foldable Specification of Letters Patent.

legs B, B, each of which may consist of a rod threaded at one end and pivotally secured at said end within the cavity of a depending portion of an angleiron bracket 0, which may be bolted or riveted to the frame or body of the forge, as shown, so as to adapt the leg to swing on its pivot into a position substantially at right angles to the bracket, underneath the body of the forge, as shown in dotted lines in Fig. 2, and be secured in such position by means of a lock'nut D, fitted upon the exteriorly threaded end of the leg and adapted to seat against the angular end of the bracket, when the leg is arranged in a position perpendicular to the base, or against one edge of the angle-iron when the leg is turned up under the forge body into the position shown in Fig. 2 in dotted lines, whereby said leg may be adjusted and locked in either of such positions. Preferably a washer E is interposed on the leg B between the nut D and the pivot both for contact with the bracket end or edge according to the position of the leg. It will be understood, of course, that a greater or less number of legs than four may be used, four being usually employed in forges of the type shown, although three will suffice. In order that the leg, when thrown up into the dotted line position shown in Fig. 2 and locked, may touch the bottom of the forge, as indicated in dotted lines, I preferably cut away one edge of the bracket, as at 0, providing a shoulder, as at 0 (Figs. 2 and 3) against which the washer E will strike when the leg is raised, and the washer being seated against the inclined surface 0 will securely and firmly hold the leg in an elevated posi tion against the bottom of the forge and when the legs are swung back into normal position, by turning the nut, the washer will be forced tightly against the angular in either normal or folded position. The inclined. shouldered portion of the bracket permits the leg when folded to make close contact with the underside of the blower, as shown in dotted lines in Fig. 2, and at the same time affords greater security against displacement than a straight edge. However, the inclined feature may be dispensed with.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A foldable self-bracing leg for a knockdown forge or the like, comprising an angle-iron bracket adapted for attachment to the forge frame or body; and a rod pivoted at one end within the angle of said bracket and having an adjustable locking device thereon engaging the angular end of the bracket so as to lock the leg thereto in the plane thereof; said locking device being movable along the leg and adapted to engage one edge of the free end of said angle-iron when the leg is turned and lock the leg in a position substantially at right angles to said bracket.

2. In combination with a knock-down forge or the like, a foldable self-bracing leg consisting of an angle-iron bracket depending from'the forge frame or body, a rigid arm or leg proper having a threaded end pivoted to said bracket within the angle thereof and adapted to be swung up underneath said body into position substantially at right angles to said bracket, and a nut screwed on said threaded end and adapted to engage the angular end of the bracket and lock the arm thereto in the plane thereof, and to engage one edge of the angle-iron when the arm is turned substantially at right angles to the bracket and lock said arm in the latter position.

3. A knock-down forge comprising a foldable frame or body and self-bracing foldable legs therefor consisting of angleiron brackets secured to said body and having pendant portions and legs having threaded ends pivoted to said pendant portions; said legs having adjusting devices thereon adapted to engage the angular end of the bracket when the leg is in normal position and to engage the edge of the bracket when the leg is swung into a position substantially at right angles to the bracket, and to lock the leg in either position.

4:. I11 combination with a portable forge, a foldable self-bracing leg comprising a bracket of angle-iron depending from the forge body or frame, an arm or leg proper pivotally secured at one end to said bracket in the plane thereof and adapted to be turned up under said body, substantially at right angles thereto, and means for locking said arm in either of said positions, said means consisting of a nut screwed upon said arm, and a washer interposed between said nut and the pivot bolt, said washer being adapted to engage the free end of the bracket when the arm is in normal position and to engage one edge of the bracket in another position of the arm and lock the leg in either position.

In testimony that I claim the foregoing as my own, I affix my signature in presence of two witnesses.

HENRY B. KEIPER.
