Application led October 28, 1907. BeralNo. 399,498,

To all 'whom 'it 'may concern:

Be it known that I, JOHN HOWELL SULLI- VAN, a citizen of the United at Grand Rapids,rin the county of Kent and .State of Michigan, have invented certain new and useful .Improvements in Fastening Devices for Molds.; and I do declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appar# -talns to make and use the same.

In the organization of concrete building walls it is customary to employ molds cornposed of sections or boards arranged in vertical edgewise relation and having their meeting edges temporarily connected by means of fastening members yor clips, such, for example, as that illustrated in Patent No. 813,253,

points of engagement with the fastening" clips.

'It has alsoY been foundA necessary when using the clip in question to employ sections or boards of a uniform thickness in order that the clips may be properly engaged therewith.A l

The present invention has for its object lto provide a simple, inexpensive form of fastening member which may -be conveniently eniployed .for connecting the adjoining ends of the mold sections at the angle of the wall and which further -provide when used at the meeting point in the mold for` the ready disengagement of the boards .or sections of the latter without injuringthem.

A further object of the invention is to provide a simplified form ofv clip through the medium of which boards of varying thicknesses may be employed in the formation 'of the mold, and one by which these variable, boards may be readily and securely connected.

States, residingv With these and other objects in View, the invention comprises the. novel features of construction and combination of parts more fully hereinafter described.

' In the accompanying drawings, Figure 1 is a perspective view of a portion of a mold having the sections thereof connected by 4means 'of fasteningl clips embodying the invention; Fig. 2 is a perspective view of one `of the improved clips Fig; 3 is a plan view of the blank from which the clip is made and showing the same prior to bending into shape; Fig. 4 is a perspective view showing a slightly modified embodiment of the in- Vention, -and Fig. 5 -is a plan viewof thel blank `for composing the clip shown in Fig. 4.

Referring to thedrawings, and particularly to Figs. 1, 2 and 3, it will be seen that.

the improved clip which Vis, composed of sheetmetaland made in one piece, comprises a body portionl having two sets or pairs of spaced engaging portions or flanges, 2 and 3, arranged respectively in planes at right angles to each other, there being formed on ,the body 1 and at a point centrally between the flanges 3, a flange 4, vprojecting at right angles to the plane of the anges 3 and in turn provided with 'an opening 5,.'whi1e projecting from the body 1 at a point centrally between the flanges 2 and in a plane at right angles thereto, 1s a supplemental flange 6 having an opening 7. Formed in thebody 1 at points near its ends are openings or-perforations 8 for the reception'of screws or otherfasteningmembers by means of which the clip maybe attached to one of the moldl sections or boards.

In the formation of the fastening member, aV sheet metal blank such as illustrated in Fig. 3 is serrated transversely at the oints 9 to provide the several portions or anges. i

2, 3, 4 and 6 which in completing the ,fastening member are bentrelatively tothe body portion 1 and to one another in the manner heretofore explained and 'as clearly illustrated in Fig.

y In` practice, the clip is employed for connecting the sections or boards forming the 4mold as illustrated in Fig. 1, the clips at one side of the vmold being connected with those at the op osite side by means ofl tie rods 10.entere .respectively the openings 5 and' 7, these rods being' adapted for exertingtension on the clips to drawthe mold sections tightly together. It is'to be particularly observed that in the use of the device, boards of different thicknesses may be employed in the formation of the mold; and, further, that after the casting or molding operation, the clips may be quickly disconnected from the boards to permit of their removal from the molded article.

In the form of device disclosed in Figs. et and 5, the body portion 1 has formed thereon the right-angularly disposed portions or flanges 11, 12. corresponding to the

flanges

2 and 3 shown in the other form of the device, and a flange liydisposed in av plane eentrally between the flanges 11 and parallel therewith, but at right angles to the plane of the flanges 12, there being formed in thev flange 13 an opening 14 for the4 tie rod, and

in the body 1 openings 15 tol receive fasten-v Having thus fully described my invention,

what I claim as new and desire to secure by Letters-Patent, is:

1. A fastening member of the class described, comprising a body portion and bearing flanges, a pair of said flanges being ar ranged in a plane at right angles to the plane of another pair, and a pair of auxiliary flanges projecting from opposite sides of said body portion in planes at right angles to each other.

2. A fastening member of the type described comprising a body portion having bearing flanges extending from opposite sides thereof, a pair of said flanges extending from one side of said body at opposite ends thereof and having a flange projecting betweenvthem in a plane at right angles thereto, and with a flange extending from the opposite side of said body intermediately of its` ends and in the same plane therewith.

3. A fastening member of the class described comprising a body portion having bearing flanges extending from opposite sides thereof, a pair of said flanges extending from one side of said body at opposite ends thereof in a. plane at rightcangles to the body portion and having an intermediate flange projecting between them, and a. pair of said flanges arranged at opposite ends on the other side of said body and having an intermediate flange projecting between them and at right angles to the other intermediate flange.

4. A fastening member of the class described comprising a body portion having a plurality of bearing flanges extending from opposite sides thereof, a pair of said flanges extending from one side of said body at opposite ends thereof in a plane at right angles. to the body portion and`having an intermediate flange projecting between them in the same plane as said body portion, a pair of flanges extending from the opposite side of said body portion at its opposite ends and in the same plane as said body portion, and an intermediate flange projecting bctween said last mentioned pair of flanges in a plane at right angles thereto.

5. A fastening member of the class described comprising a body portion having a plurality of bearing flanges extending from opposite sides thereof, a pair of said flanges extending from one side of said body at opposite ends thereof in a plane at right angles to the body portion and having an intermediate flange projecting between them in the same plane as said body portion, a pair of flanges extending from the opposite side of said body portion at its opposite ends and in the same vplane as said body portion, and an intermediate flange projecting between said last mentioned pair of flanges in a plane at right anglesthereto, and in an opposite direction to said pair of flanges on the opposite side of the body portion and in a plane parallel therewith.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
