JOHN H. MONTSTRIEAM, F HARTFORD, CONNECTICUT.
Janos-HAMMER.
Application filed December 8, 1915.
To all whom it may concern:
Be it known that I, JOHN H. MoN'rsTREAM, a citizen of the United States, residing at Hartford, in the county of Hartford and acter receives the blow of the dropped heavy hammer it necessarily under the impact yields a little, that is, it to a slight extent is driven downward, and the uprights being supported by and rigidly secured to the anvil, as they commonly are, must of course go down with the anvil. Owing, however, to inertia, when the anvil yields under the impact of the blow of the hammer, the uprights do not yield as quickly, consequently there is a sudden strain on the fastening means or stress in the metal at the joints between the uprights and the anvil which after a time causes the uprights to become cracked and break off from the anvil.
The object of this invention is to so design and connect the anvil and the uprights supported thereby that the tendency to breakage of the fastening means or of the uprights to tear from the anvil is eliminated,
"9' and also to at the same time provide means by which the hammer guides may be readily adjusted so as to take up wear and keep the dies in match. 7
To attain these ends the uprights are mounted upon and supported by the anvil as is usual in this type ofmachine, but they are fastened thereto with a sliding fit so that the anvil can yield slightly-under the impact of the blow of the hammer without drawing down or putting a sudden tensile strain on the lower ends'of the uprights, or the means commonly used to secure the uprights to the anvil, and by hinging the hammer guides at their upper ends to the uprights and arranging means for adjusting their lower ends transversely of the anvil so that the die block carried'by the hammer and the die block mounted on the anvil will properly match.

Serial No. 65,679.
shows a front elevation, with part in section, of the anvil, uprights and hammer of a machine constructed according to this invention. Fig. 2 shows a side elevation of the same. Fig. 3 shows a horizontal section across the anvil taken on the plan indicated by the dotted line 8-43 on Fig. 2. Fig. 4 shows a horizontal section taken across the uprights on the plane indicated by the dotted line l4 on Fig. 2.
The anvil 1 is preferably a heavy casting of iron with vertical grooves 2 in its side edges and vertical wings 3 that project out-' wardly sidewise into the grooves. The wings are made quite substantial, but in the frame illustrated they do not extend to the top or to the bottom of the grooves. H0rizontal openings 4 are made transversely through the anvil above the top and below the bottom edges of the wings. In the top of the anvil and adjustable toward the front and back is the usual-die block 5 for'holding the die 6.
The uprights 7 have their lower ends adapted to fit loosely in the grooves in the side of the anvil. The inner inclined faces 8 near the outer edges of the lower ends of the uprights are shaped to fit against corresponding inclined faces 9 on the anvil near the outer edges of the grooves. The parts are held together with a sliding fit between these faces by the rods 10 and nuts 11, the rods being shouldered so that when the nuts are turned up the uprights will be firmly heldwith their inclined faces fitting the inchned faces on the anvil. The rods which hold the uprights pass through the openings 4 in the anvil, which openings are larger in d ameter than the rods .so as not to interfere with their up and down movement. The lower ends of the uprights on the inner sides are recessed, and when the uprights are placed in position on the anvil the wings extend into these recesses so the uprights will rest upon and be supported by the wings. Cushions 12, preferably of leather, are placed between the supporting wings and the uprights which are supported thereby to relieve shock. v
lVith this construction the anvil can yield slightly under the impact of the blow of the hammer without carrying down the uprights. This movement is so quick and slight that gravity does not have time to overcome the inertia of the uprights and the anvil yields and comes back before the uprights have a chance to move down. Of
course, thisvmovement isvery slight, but the;
the anvil, or to rupture the uprights so that they become broken off from the anvil. When the uprights are held to the anvil with a sliding fit as herein described, which permits a slight relative movement between the parts, the uprights canbe made very much lighter than they are in drop hammers as commonly constructed where the uprights are rigidly connected with the anvil, and although made-much lighter the uprights will notbreak or tear off from the anvil.
The die block 5 and the die 6 which it carries are adjustable in the usual manner toward the front and back, as is the die 13 carried by the hammer 14. For the purpose of adjusting the hammer die transversely, that is, sidewise so that it will match with .the anvil die, the hammer guides 15, which are usually made of hard steel, are hinged to the uprights at their upper ends by bolts 16 and are clamped to the uprights at their lower ends by bolts 17. When the lower bolts are loosened the hammer guides may be adjusted sidewise by the bolts 18 so that the hammer die'will match with the anvil die.
The invention claimed is;
1. A drop hammer frame comprising an anvil, uprights supported by and movable vertically relatively to the anvil, and means holding the lower ends of the uprights to the anvil the construction being such that a slidable fit between the uprights and the anvil is provided.
2. A drop hammer framecomprising an anvil, uprights supported by the .anvil, and means holding the uprights to the anvil in such manner that the anvil may move down ward independently of the uprights.
3. A drop hammer frame comprising an anvil with wings projecting outwardly from the sides of the anvil, uprights supported by said wings, and means holding the anvil and the uprights firmly together without interfering with the vertical movement of the anvil relatively to the uprights.
4. A drop hammer frame comprising an anvil-having grooves in its sides and wings extending into the grooves, uprights loosely fitting the grooves and resting upon the wings, and means for holding the uprights to the anvil.
5. A drop hammer frame comprising an anvil with grooves in its sides and wings extending into the grooves, uprights slidably fitting the walls of the grooves and resting upon the Wings, cushioning material be tween ,the Wings and the uprights, and rods and nuts passing loosely through the anvil and holding the uprights in position.
6. A drop hammer frame comprising an anvil, uprights with their lower ends fitting into the sides of and supported by the anvil, and means holding the lower-ends of the uprights to the sides of the anvil in such manner that there can be no relative transverse movement but can be a slight relative vertical movement of one part with relation to the other.
' 7. A drop hammer frame comprising an anvil, uprights supported by the anvil, means securing the uprights and the anvil together transversely without interfering with'a vertical movement of one part with relation to the other part, a die block adjustable toward and from the'front and back of the anvil, and hammer guides mounted on the uprights and adjustable transversely of the anvil.
