CARL E. KNUTSEN AND OLE KNUTSEN. OF NEW YORK, N. Y.
IRON-SHAPING MACHINEW Patented Jan. 1 5,1907.
To all whom it may concern:
Be it known that we, CARL E. KNUTSEN and OLE M. KNUTsEN, of Brooklyn, county bed-plate.
of Kings, city and State of New York, have invented certain new and useful Improvements in Iron-Shaping Machines, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, wherein Figure 1 is a front elevation of our improved bridle-iron-shaping machine. Fig. 2 is a bottom view of the plunger and of the mechanism connected therewith. Fig. 3 is a plan view of the anvil-bench; Fig. 4, a sectional view thereof on lines 4 4 indicated in Fig. 3. Fig. 5 is a side elevation of the plunger and anvil-bench, showing the bar to be shaped in position in the machine. Fig. 6'- is a cross-sectional view on line 6 6 indicated in Fig.- 1, and Fig. 7 a cross-sectional view of the anvil-bench on line 7 '7 indicated in Fig. 3.
Our invention relates to machines for shap ing structural iron; and it consists of the de vising of the hereinafter-described machine for shaping bridle-irons.
The machine comprises a stationary anvil or bed shaped conformably with the form to be given to the iron subjected to the operation of the machine and provided with means for setting and securing the iron to be shaped in position, av movable plunger, and'of dies for shaping (twisting) the iron, and of means for adjustably and movably securing' the dies to the plunger, and of suitable mechanism for operating the plunger.
Referring to the drawings, particularly to Fig. 1, numeral 8 designates a stand or frame, preferably made of cast-iron, wlrereon the anvil or bench 9 is secured by bolts 10. anvil or bench comprises a bed-plate (shown in end view and cross-section in Figs. 5 and 6, respectively) and two side blocks 11, one on each end thereof snugly fitted upon the bed-plate. The side blocks 11 are slotted, and corresponding slots are provided in the Through these slots 12 bolts 13 are inserted, and by means of these bolts the side blocks are secured to the bed-plate in adjusted positions. Turn-bolts 14 are pivoted to the upwardly-projecting flange 9* of the bed-plate, and catches 15 are secured by screws 16, one to each side block 11 in posi tion to be engaged by the corresponding turn-bolt 14. The bar of iron 31 to be shaped (twisted) is laid between the flanges 9 and the faces 34 of blocks 11, its middle The portion, whereon the plunger 17 and the twisting-die 26 operate, being free. By looking turn-bolts 14 underneath the catches 15 the bar 31 is held firmly in position on both ends.
The anvil-bench 9 is stationary, and the plunger 17 has a vertically ascending and de scending motion, while the die-frame is movable laterally to enable the die to remain in contact with the bar acted upon in the operation of the machine. The motion of the plunger may be produced by any suitable mechanism, preferably by such mechanism as is commonly employed in power presses or shears. This mechanism not being part of our invention is not shown or more fully described herein.
In plunger 17 two dovetailed grooves 18 are provided, and brackets 19 are fitted to slide therein. These brackets are fixed in opposite position relatively to the plunger 17 by set-screws 20, and they connect to and support on the plunger the die-frame, composed of side plates 21 and adjustable ties 22. Side plates 21 are provided with flanges- 21, snugly fitted into the grooves produced by the recesses of brackets 19 and the lower face of the plunger. They are also provided With flanges 21 projecting above the edge of the plunger and abutting against the plunger when the die-frame is pushed inwardly, thereby restricting and arresting its motion. 1 The outward motion of the die-frame is arrested by drops 23-.
For the better convenience handling the die-frame while the machine is being operated a handle 24 is provided. It is secured to the ties 22 and projects some distance beyond the face of the plunger.
A die 26 is affixed by screws 25 to each of the side plates 21 of the die-irarre. It is preferably made of cast-steel and shaped as shown in Fig. 6. The forward face of the die 26 is slightly curved or beveled, as shown in Figs. 5 and 6. The shape of the die is determined by thenature of the work to be performed-by it.
The operation of the machine 1s as follows: The bar 31 to be shaped into a bridle-iron is inserted between the flange 9 of the anvilbench and the inner faces 34 of the side blocks 11. It is laid against the faces of these side blocks 11. and held in that position by turn-bolts 14, which are then turned and slid underneath catches 15. Then the mechamsm operating the plunger is started.
As shown in Figs. 5 and 6, the path of the edge (designated 29 in the drawings) of plunger 21 projects slightly beyond the upper edge of bar 31 in its slanting position, and thus when the plunger descends this edge 29 strikes the portion of the bar 31 lying between the side blocks 11, and by forcing it down that part of the bar 31 thus engaged by the plunger is partly twisted, its upper edge being diverted toward the front of the machine. By this partly twisting the bar the diverted edge thereof is brought in line with the motion of the beveled or rounded edge 26 of the die. Then the plunger ascends, and on its return (downward) motion this edge 26* engages the partly-twisted bar and completes the operation by turmng that part of the bar between side blocks 11 in line with the slope 33 of the bed-plate. This twisting .of the baris accomplished by the combined motion (toward the front of the machine) of the edge of bar 31 as the process of twisting progresses. By these means all friction between the bar 31 and the die is avoided, and no displacement of the die 26 relatively to the bar 31 takes place durlng the operation. The plane of slope 33 of the bed-plate is exactly at right angles with the faces 34 of side blocks 11, against which the ends of the bar 31 rests, and thus the middle portion of the bar (between the side blocks 11) is thereby brought in a position exactly at right angles to its ends.
To facilitatea speed and secure inserting of the bars to be operated upon in the machine and to produce the twisting exactly in the place desired, a gage 35 is provided (shown in elevation in Figs. 1 and 5) and is secured in adjusted position by hand-screw 36 passing through a slot in the gage 35 lnto a screw-thr eaded bore in the anvil-bench.
We claim as our invention- 1. A machine fortwisting bridle-irons comprising a frame, a flanged bed, side blocks adjustably secured to the bed; the bed and the blocks being molded conformablyto the the blocks being molded conformably to the shape into which the bridle-iron is to be twisted; turn-bolts pivoted to the bed and catches secured to the side blocks in position to engage the turn-bolts; a plunger and a dieframe; means for movably supporting the die-frame on the plunger; dies affixed to the die-frame and means for operating the plunger; substantially as herein shown and described.
3. A machine for twisting bridle-irons comprising a frame, a flanged bed, side blocks adjustably secured to the bed; the bed and the blocks being molded conformably to the shape into which the bridle-iron is to be twisted; means for firmly holding the iron to be twisted, against the bed and against the side blocks; a plunger; brackets adjustably affixed to the plunger; a die-frame movably supported upon the brackets; dies affixed to the die-frame and means for operating the plunger; substantially as herein shown and described.
4. The combination in a machine for twisting bridle-irons, comprising a frame, a flanged bed, side blocks adjustably secured to the bed; the bed and the blocks being molded conformably to the shape into which the bridle-iron is to be twisted; a plunger and means for reciprocating the plunger, of means, substantially as herein shown and described, for movably connecting dies with the plunger.
