SHEET-METAL BOLT-ANCHOR.
Specification of Letters Patent. Patented} -M[a,y 27, 19119,
Application filed December 24, 1914. Serial No. 878,844.
To all whom. it may concern:
-Be it known that 1, JOHN EbwARD OGDEN, a'citizen of-the United States of America, and a resident of Mountainville, town of Cornwall, county of Orange, and State of New York, have invented certain new and useful Improvements in Sheet-Metal Bolt- Anchors, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.-
My invention relates to bolt anchors and the like and has special reference to such as are formed from sheet metal.
One object of my "invention is to provide a simple device of the aforesaid character which may be manufactured in large quantities at small-cost and which shall possess the'combined advantages ofi cast" metal anchors and sheet metal anchors as hitherto constructed. In other words, it has been my;
aim to provide a sheet metal anchor which may be produced by a' simple punching or stamping process and have the resiliency of sheet metal while it at the same time has walls of varying thickness as well as a tapering opening'and is adapted to receive the threads of a bolt.
While the bolt anchors of my invention maybe readily formed from commercial sheet metal such as sheet iron, steel, or copper,- having a substantially uniform thickness, I have .used the term sheet metal herein in a broader sense and intend .to mclude not only what is commonly known.
as sheet metal but also rolled metal such as lead or cast or wrought metal such as mal- "leable iron which is adapted to be folded to produce the results desired.
,Other'objects, and advantages-of my invention will" be set forth hereinafter, and in order .that my invention may be thoroughly understood, 1 will now proceed to describe the-same, in the following specification and appended claims.
.eferrin'g to the drawings igure 1 is a side elevation of a bolt anch01. fonned in 'accordance with and embodying my invention. Y A longitudinal section of the same anchor is shown in Fig. 2.
Fig. 3 is an end elevation of the anchor and Fig. 4 is a sectional view takenonthe line H'of Fig 2;
then point out the novel. features thereof in;
Fig. 5 shows a development of the anchor into one. plant Fig. 6 isa view corresponding to Fig. 5 and illustrates the application of my invention to a two-part anchor instead of to a one-piece structure.
. Vario s modifications of my invention are shown in side elevation in Figs. 7 9, l1 and 13, and in end elevation in Figs. 8, 10, 12 and 1 1, the end views being drawn to a larger scale.
-' Still another modification is shown in Fig. 15.
Fig. 16 is a side elevation of another modi-. fication of my invention.
Fig. 17 is an enlarged sectional view of the I same, taken on the line 1717 of-Fig. 16'
and
A development of one of the 'sheet metal parts of the same structure is shown in Fig. 23. A H
Fig. 24 is a sectional view showin a portion of another form of anchor which also embodies my invention, and in .which the thickness of metal is increased by a single overlap in one section and a doubleoverlap in the adjacent section.
My invention is obviously notrestricted Fig. 18 is a development of the body of' Fig 22 is an end elevation with a part of one wall'broken away and shown in section.
to either a one or a two-piece anchor, and in fact it is equally applicable to an anchor 'cor i ilposed of any number of parts.
e structures shown in the. drawings are intended only to illustrate my invention and it is evident that v'ariousother modifications may be producedwithin the spirit and scope of my invention and I intend that only such limitations be. imposed as are 1 indicated in appendedclaLinisl J- Referringto'Figs l major the swin s,
the structurehere shown comprises an ancher'or shell 20having a substantially cylind'r ical exterior-that is, adapted tolargely engage the walls "of a cylindrical -hole. and a tapered opening'21 which is. circular at its outerend 3 116.18 elliptical in formatits inne r.end. 'lhelshell'comprises two members .into a single plane, or separate '22, a rectangular middle ion. 23 and form the inner end of the completed shell.-
As clearly shown in Fig. 1, the flaring cor-1 ners 25 and 25? of the section 25 are folded back upon the central portion, of this section and overlap each other. The lines upon which the wings 25 and 25 are folded are not eontinuations of the sides of the rectanular section 23 but are tapered gsshown in dotted lines 26, in Fig. 5. By this means the opening, 21;v f the shell is made tapering, as clearly shown members 20' and 20 are bent into substantially cylindrical form.- and the outerend of theshell is fashioned by drawing the same through a suitable die. If the members are made in separate pieces they are united at their outer ends along the ing, welding or some other suitable means.
7 Attentionis directed to'th'e fact that while the interior opening 21 is tapered for the reason above set forth the outer the shell is substantia ready explained because the walls at the inher end are thickened b 'the folding of the ' portions 25 and 25 he sections 22 together constitute means for recei the threads of abolt, the corrugations ing' suitably inclined m the axis to efiect this re,- su t.
' WhileI have referred to the opening a her, by
tapered ope it may be either uniformly angered t oughout or ta red only in an ce section or sections an otherwise cylindrical; in fact it 1s usual to having a cylindrical sectionnearthe middle .or at the outer end of the opening.
- The ancho in a well-known mandriven into a hole in a wall of concrete or like material hich will not hold the threads f a bolt, and a bolt or-other ded member which is to be supscr ew chrea ported, screwed Into the anchor. "A'stbe causes it to be very securely wall in which it is placed.
.Thecorners ofthe may be cut oil" and bent outwardly, forming frelatively short longi'tndinal' ribs 30',
astenedin the be integral and have ,to form grooves tending ribs 32 as the rectangular secin Figs. 2, 3 and 4. The
edges'27 by-solderout the wings. The
ly cylindrical as alafter the anchor is inserted it expands the anchor on account of the tapered opening 21 and in preventing-the removal asshown with slots 39. Tha anchor is formed 7.1.1 8. This modification or Thy-invention T is otherwise similar to thestructure above described. u
As shown in Fi s. 9 and 10, the rectangular portion 23 of t e anchor may be indented 31 or the metal may be to form outwardly exshown in Figs. 11 and 12. The ribs are not necessarily longitudinal but may extend at an angle as shown at- 33 in Figs. 13 and 1 k. These ribs lend to prevent rotation of the sleeve in the-hole into which it is "inserted. The grooves 31 provide pockets into which Wedges or'nails' may be driven between the shell and the. wall, and so prevent the rotation of the shell.
' In order to assist in preventing the removal of the shell from the, hole, such as the ribs 34-, shownin Fig. 15, may be employed.
forced outwardly lateral-ribs a The inner 'endsof the shells may be prop ace vided with of those at the *outer ends or in them. For example, the overlapping wings 25 and 25 may have projections as shown at 60in Fig. 9. Ribs, such 11), may be formed in the corrugated part of the shell under. the wingls, and serve'to increase the resiliency of e shell by holding 'bs 'may'be formed by ribs or projections either m pressing out the meta out cutting the sheet me Various combinations ofdiflerentiorms of ribs 'or pro-' jections' may be effected within the scope of my invention.
'- Referring to Figs. 1 and 17 at anchor here shown comprises a cylindrical body 36,"
in thickthe walls of; which are inc ness near its outer end 'as shown inner end of the slots 39 are body which open into-diamond-slzfed holes 40in the ,flariniosgction 38. In dition to the cylindrical y the anchor comprises a nut 41 having conically curved exterior walls to form a plug and diamond-shaped projections 42 which extend into the holes 40. The arrangement of parts 15 at. 37. The at 38 and into the nut 41, the nut will be drawn into either with or withprovided in opposite sides of the addition to as 61 (see Fig.\
such that in a-hole and a the flared end of the anchor which will be expanded, both on shape of the nut wedge shape of theproj'ections 42 Vance into the slot8l39. The body of this anchor is formed account of sheet metal and when developed. into'asln' gle plane The metal has .the shape shown stamping from which is formed has a rectangular the anchor portion 36 in which the slots 39 and the holes 40 are cut and a projection 36" the rectan hich is' narrower than gu ar portion 36, and is providfid y Fig. 18".
the conical and on account of the hich rolling the sheet metal stamping into a cylindrical form, the arrangement being such that the slots 39? coincide with the slots 39 and form a part of them in the completed .anchor. The projection 36 wraps around the outside of the anchor and increases the thickness at its outer end. The inner end of the anchor is flared as already described.
The method outlined above may be employed with equal facility to a double eX- pansion anchor having the arrangement of expansion members shown in Fig. 19. The stamping then would have two integral sections each like Fig. 18.
The thickening of the walls of a sheet metal bolt anchor, by folding, is also exemplified by the structure sho-wn'in Figs. 19 to 23 of thedrawings. This modification may comprise either a two-part or a onepiece tubular body 45 which has a substantially cylindrical central section 46 and a pair of similar; outwardly flaring end sec-' tions 47.
The thickness of the central section is increased by folding so that the general form of the exterior of the anchor is cylindricalwhile its interior opening is ta pered inwardly from each end.
In a two-part shell the sheet metal parts are identical and each of them has the form shown in Fig. 23, when developed into a single plane. The stamping as here shown has lateral projections 48 which are adapted to be folded back onto the body of the stamping on the dotted lines. The corners of the stamping are provided with notches 49, the notch of one sheet metal part of the anchor coiipe-ratlng with an adjacent notch of the other part, as clearly shown in Fig. 20, to provide a triangular opening 50.
A taper nut 51 having wedge-shaped lateral pro ectlons 52 is located in one end'of the sheet metal shell, with the projections 52 disposed in the triangular openings 50 of the body having two similar semi-cylindrical shell.
The taper collar 53 is provided with similar projections 54 which extend into the openings 50 at the opposite end of the shell. The two parts of the shell may be fastened 'togethe'r by any suitable means such as, for
example, resilient hoops 55.
The anchor is utilized in a well known manner, as clearly shown in Fig. 19. The
nut and the collar 53 having been mounted 1n the respective ends of the shell,
the latter is inserted in a hole as shown in the drawing with the nut 51 at the inner Attention is directed to the .fact that the J body of the anchor is reversible, end for ing employed.
- symmetrical in shape.
The stamping for the one-piece shell will have two sections each resembling Fig. 23, except that the wings will only be provided on the non-adjacent edges of the sections and may be made longer to provide the desired increase in thickness.
The folded wing arrangement may of course be made single instead of double ended, if desired, only a single expansion member like-the member 41 of Fig. 16 be-' In Fig. 24 I have shown a portion of a shell one end of which is thickened by folding the metal three times instead of once. By this means the end of the. shell has four thicknesses of metal as shown at 65 while the adjacent section has two thicknesses and l the opposite end only a single thickness..
The number of folds is not important and depends on'the thickness of metal desired, for example the fold might be made double or quadruple instead of triple and in the form of a tuck, plait or hem.
What I claim is: e
1. A bolt anchor comprising a tubular 2. A bolt anchor comprising a tubular,
