METAL-BENDING- DEVICE.

Specification of Letters Patent.

ratented oef. 2s, 1919.`

Application filed August 12, 1918. Serial No. 249,471.

To all whom t may concern.'

Be it known that I, PERCY SATTERLEE, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Metal- Bendinof Devices, of which the following is a specilcation, reference being had therein to the accompanying drawings.

My invention aims to provide novel device or tool for bending angle irons, rods, wires and various kinds of stock, the bending being expeditiously and safely performed and in a manner which insures uniform bends when a plurality of pieces of stock are to be similarly shaped. Y

My invention aims to provide a tool that may be advantageously used for bending rey inforcing rods and wires in Concrete construction, for bending the projecting ends of rods or bracket Wires in concrete oonstruction where these rods and wires project from the wall for the purpose of supporting moldings and ledges, and as a bench tool for bending clips and other articles for building construction. To accomplish such bending for the above and other purposes the tool is necessarily adjustable to' accommodate different kinds of stock and permit of the stock being bent to desired form.

My invention further aims to accomplish the above results by a simple, durable, portable and inexpensive device that will be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein there is illustrated a preferred embodiment of my invention, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

In the drawings,

Figure 1 is a perspective view of a metal bending device;

Fig. 2 is a plan of the same, partly broken away, and

Fig. 3 is a cross-sectional view taken on the line III-III of Fig. 2.

In the drawing, the reference numeral 1 denotes an arm having the outer end thereof provided with a flat semi-circular head 2, and adjacent therstraight edge 3 of said'head Vso that various kinds of is an overhangin bracket 4' disposed 'in parallelism with t ehead 2 and preferably formedintegral with said head at its juncture with the arm 1. The bracket 4 has an upstanding lug 5 and said lug is apertured to receivel a screw or stove bolt 6 for holding a face plate 7 in engagement with said lug, said bolt having slotted shims or washers 8 and a nut 9. With such fastening means as the bolt 6 and nut 9, Vit is possible to place the shims 8 between the lug 5 and the face plate 7, and such adjustments may be made stock. may be bent or shaped bythe device.

The bracket 4, adjacent the lug 5, has an oblong opening 10 alining withy a .similar opening 1l in the head 2 and these openings have walls inalinement with one side of a depending channel shaped member V12 carried by the head 2 and adapted for holding an invertible post 13. The'post 13 conforms in cross sectional area to the openings 10 and l1, said post extending therethrough and confronting the face plate 7 of the lug 5. The post has its ends apertured, as at 14, and one end thereof reduced as at l5, the apertures 14 permitting of either end ofthe post being attached to the member 12`by a screw bolt 16 and a nut 17. end of the post 13 permits of said post being inverted to increase the Vspace between the upper end of the post and the face plate7 ofthe lug 5.

Held between the head 2 and the bracket 4 by the post 13 is a non-rotatable eccentric 18 surrounded by the head 19 of an arm 20 said arm being free to swing about the eccentric between the bracket 4 and the head2 of the arm 1.

The head 19 of the arm 20 is provided withran oblong apertured boss 21 and mounted in one of the apertures of said boss is a detachable stud 22 supporting a revoluble anti-frictional roller 23, and the distance between said stud and the post 13 may be decreased by adjusting the stud from the position shown to the inner end of the boss 21.

The arm 20 is provided with a depending lug 24 adapted to ride against the semi-circular wall 25 of the head 2, and this semi- -circular wall or the top of said head may be marked to indicate the position to which the arm 20 -has been swung over said head,

consequently it is possible to uniformly bend a plurality of pieces of stock.

The arms 1 and 2O are apertured, as at 26 so that the arm 1 may be secured to a bench or suitable support or power operating means may be attached to vsaid arms.

For the convenience of describing ythe use of the device I will consider the arm 1 as stationary and the arm 20 as the operating or bending element of the device. The arm 2O has been shown as in extreme position, and assuming that said arm is swung in front of the head 2 in proximity to the arm 1, a piece of stock is placed between the post 13 and the face plate 7 of the lug 5, with the stock end to be bent protruding outwardly from the post 13 over the head 2. T he arm :2O is then brought into engagement with the end of the stock, and in reference to Fig. 2, swung in a clockwise direction, causing the end of a piece of stock Vto be bent around the faces of the post 13, the curva.- ture of the bend depending on how far the arm 20 is shifted. With the arm 2O in an extreme position, as shown in Fig. 2, the end of a piece of stock will be practically bent on itself or in parallelism with the body of the stock.

lith the pivoted end of the arm 20 in eccentric relation to the post 13, the stud 22 approaches the post 13 when the arm 20 is retracted to normal position, and as said arm is swung during a bending operation, the stud 22 travels away from the post 13 and through the medium of the antifrictional roller 23 gradually bends a piece of stock without any danger of the same cracking or suddenly snapping. A sharp bend may bevmade by adjusting the stud 22 to a position close to the post 13 and it is through the medium of the shims or filler plates 8 and the invertible post 13 that p-ieces of stock of different thicknesses may be bent by the device.

1. A metal bending device comprising arms adapted to be manually moved to and from each other, one of said arms having a head and an oiferhanging bracket, an invertible post extending through the head and bracket of said arm, means carried by said bracket adapted for holding a piece of stock thereon, the other arm being eccentrically held by said post between the head and bracket of the first-mentioned arm, and a stud carried by the last-mentioned arm and adapted to coperate with said post in bending'a piece of stock placed on said bracket.

2. A metal bending device comprising a stationary arm having ahead and a bracket, an invertible post extending through the head and bracket of said arm and having one end thereof held below said head, adjustable means carried by said bracket and confronting said post adapted for holding a piece of stock in engagement therewith, said post having one end thereof smaller than the other so that said post may be inverted to increase or decrease the space between said post and said adjustable means, an eccentric on said post between the `head and bracket of said stationary arm, a. m0vable arm held by said eccentric to swing over the head of said stationary arm, and a stud on said movable arm adjustable to and from said post and adapted to coperate therewith in bending a piece of stock held in engagement with said post.

In testimony whereof 1 affix my signature in the presence of two witnesses.

PERCY SATTERLEE.
