HENRY c. rnoivrrson,

or cLnvnLAnn, oHIoQ EEESSEIQ-METAL ARTICLE.

' Application filed May. 31,

State of Ohio, have invented a certain new and useful Improvement in Pressed-Metal Articles, of which'the following is a--full,

'

flanges

2 and 3 are being formed, although clear, and exact description.

This invention relates to a pressed metal Y article which may be broadly described as comprising a central base portion by which indicated in, Fig, 3.

Lit may be attached, and an arm orhook-like extension, or there may be 'two oppositely disposed arms or hook-like extensions:

One 03". the uses to whichsuch anarticlc "a ropes may be fastened, which ropes .sociated with. pulleys.

it is to be understood, however, that the invention is not limited to a construction for this precise purpose.

The article is initiated by forming a blank out sheet metal, and by the use of dies the metal is folded and formed until it produces the finis ed article.

Referring to the drawings, Fig. 1 is a plan view of a blank; Fig. 2 is a top plan view of the is ice when it has been partially foldt. formed; Fig. 3 is a side elevation of the wing in Fig. 2; Fig. 4 is a side elevation. of the completed article; Fig. 5 is a bottom plan view of the completed article; Fig. top plan View of the completed article; Fig. 7 is a section on the line 77 of Fig. 6, nd Fig. 8 is a section on the line 88 of It-sf rring to the drawings, and more particularly Fig. 1, there is shown a blank which has a central portion 1 with extending

arms

2 and 3. These arms at their outer ends are slightly tapered, as indicated at 2 and 3.

At the inner end of each arm there are outwardly extending

pointed portions

2 and 3", and adjacent these pointed portions are

notches

2 and 3. This blank is also provided with one or more suitable openings, such as indicated at 4, these openings being formed at the same time that the blank is cut out of the sheet metal.

In the first operation the metal isbent to provide upwardly extending side flanges 1 and 1 which are formed at the side or edge of the central portion 1, and the outer edges of the arms are also formed up into up- G. THOMPSON,

standing flanges, which are indicated at 2 and 3 In this. operation the central" openings {1 may be countersunk, thereby providin upraised ribor bead surrounding t em,

such as indicated at 4.

Preferably at the same time that, the

not necessarily, the-arms 2 aind 3'are formed 1, and toassumc acurved position, such as fianging the blank and curving the arms J may be performed simultaneously,- although this not necessarily the case.

On the next operation the edges of the

flanges

2 and 3 are rolled toward each other until the edges meet, thus forming hollow arms, so that the section through any wortion of one of the arms is approximately a circle. The diameter of any such. cross section, however, will vary sli htly from the outer end of the arm towaro the inner end. At the same time the flanges l and 1 are rolled inwardly until the edge of the flange contacts with the central portion 1, and in doing this it may be desirable or necessary to slightly out out a portion of the flanges 1 and 1*, as indicated at 1, for the purpose of accommodating the beads Whichare formed around the openings 4. The pointed por-- tions 2" and 3 will fold against the central This operation of' portion 1 at the end thereof, and provide the I slight amount of extra metal needed in order to provide for the widened. portion of the arm adjacent the part where it adjoins the central portion.

It will thus be seen that the article as described is formed from asingle blank, and when the article is finished it has all the appearance of being solid, and has even reater strength than the solid article woul have, particularly against distortion or breakage, particularly of a similar'article which was made of cast metal.

Having described my invention, I claim:

1. The method of forming a hook-like article which comprises blanking out of sheet metal a blank having a central portion and oppositely extending arms, forming said blank by moving the edges of the said arm portion and the central portion to provide upstanding flanges, then rolling over the edges of the fiangeson the arms into substantial contact thereby forming? hollow tubular arms, and rolling'the flanges formed in the central portion into contact with the central portion thereby forming a bead at the edges of the central portion which are contiguous with the arms.

2. The method of forming a hook-like article which comprises blanking out of sheet metal a blank having a central portion and oppositely extending arms forming said blank by moving the edges of the arm portion and the central portion to provide flanges which flanges are on the same side of 'the blank, also forming the said arm portions in a gradual curve with respect to the central portion and out of the plane of the central portion, subsequently rolling over the edges of the arm members into substantial contact with each other thereby to form tubular arms, and rolling over the edges of the flanges on the central portion into contact with the central portion thereby forming beads at the edges of the central portion which are contiguous with the arms.

3. The method of forming a hook-like article which comprises blanking out of sheet metal a blank having a central portion, an

antenna extending arm forming said blank by moving the edges of the arm and central portion to form flanges, then rolling over the edges of the arm into substantial contact thereby forming a hollow arm and rolling over the edges of the flanges on the central portion. to form upstanding beads at the edges of the central portion.

4. The method of forming a hook-like article which comprises blanking out of sheet metal a blank having a central portion and an extending arm, forming said blank by moving the edges-of the arm and central portion to form upstanding flanges, and also forming the arm in a gradual curve with respect to the central portion and out of the plane of said central portion,-and subsequently rolling over the edges of the flanges on the arm into substantial contact thereby forming a hollow arm, and rolling over the flanges on the central portion into contact with the central portion thereby formingbeads at the edge of the central portion.

In testimony whereof, I hereunto aflix my signature.

HENRY G. THOMPSON.
