Patented Jan. 3, 1933 UNITED STATES PATENT OFFICE GEORGE E. MCINTYRE AND LOUIS J. SMYTH, OF KANSAS CITY, MISSOURI ATTAGHING FIXTURE 7 Application filed January 26, 1931.

This invention relates to a new article of manufacture and pertains particularly to an attaching fixture which is constructed in a novel and unique manner to present elements created by forming a single piece of metal into the shape desired to embody thls 1nvention. I

One of the primary objects of this invention is to provide an attaching fixture embodying two major parts, the position and operating relation between said parts being in major planes transverse to each other.

Another object of this invention is the provision of a new article of manufacture which may be used for effectively and quickly engaging articles with which the fixture is to be associated, the parts of the device being so related that operation of the fixture is effected through a minimum amount of movement.

Minor objects of the invention, including specific refinements in construction and the combination of the various parts forming the fixture will appear during the course of the following specification, referring to the accompanying drawing, wherein:

Figure 1 is an edge elevation of an attaching fixture made in accordance with the so preferred form of the invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a side elevation of an attaching fixture embodying a modified form of the invention.

Fig. 4 isan edge elevation of the same, and,

Fig. 5 is a side view of attaching fixture illustrating the same made in accordance with still another modification of the inven- 40 tion.

The form of attaching fixture illustrated in Figs. 1 and 2 will first be described through the use of reference numerals. Like characters will be used to designate similar 15 parts shown in the two views and the numeral 6 indicates a body loop having a pair of sides 8 and 10 respectively which extend from coil 12 in substantially the same plane to shoulders 14 and 16, formed at the in- 59 tersection of sides 8 and 10 respectively and Serial No. 511,305.

at a point where arms 18 and 20 respectively join sides 8 and 10. 7

These arms 18 and 20 extend outwardly fromloop 6 in a plane transverse to the plane of said body and each arm 18 and 20 is rebent to form an arch 22 and 24 respectively. When the fixture is in the closed position arches 22 and 24 he in contiguous planes with the arches inoverlapping relation, as illustrated. Each arm 18 and 20 is formed to present a kink 26 and 28 respectively, which is positioned between the arches and the point of connection of the sides of loop 6 and the arched portion of 'the respective arm. When the fixture is closed kinks 26 and 28 are in opposed relation and move apart when sides 8 and 10 of loop 6 are pressed together. This construction insures quick and effective parting on the part of arms 18 and 20 as soon as the slightest pres- 79 sure is brought to bear against sides 8 and 10. The transverse relation between major planes of-sides and arms is responsible for this advantage and since any article itself, not here shown, willrest in the portion of overlapped arms within the arches 22 and 24, there can be no accidental parting of arms 18 and 20 until the supported article has been moved down to a point beyond kinks 26 and 28 where the same is'engaged by but one of arms 18 or20. The. operation ofthe preferred form of'this invention isobvious and its simplicity of structure, cheapness of production and novelty of design are obvious. Y With reference to themodified form shown in Figs. 3 and 4. Structural difierences are clear and it is plain-that'the major difference between the form just described and this modification lies in the relative positionof the planes of the two'major portions of this attaching fixture. In this instance the fixture is made of a single piece of wire,bent-to forma loop 5O which crosses itselfto present a pair of opposed arms 52 and 54 which ter 05 minate in arches 56 and 58 respectively. Arms 52 and 54 are each provided with 'a shoulder 60 and'62 respectively, which serve as stopsto limit the movement on the part ofiarms- 52and54 away fromeach other and also to maintain arches 56 and 58 in regisbent arm, whereby the said kinks restrict to tered relation. When the sides of loop 50 a limited degree the opening between said are pressed together shoulders 60 and 62 are arms.

moved out of engagement with each other In testimony whereof, we hereunto affix and arches 56 and 58 are moved apart our signatures.

and out of overlapped relation. The article to be supported by the attaching fixture is then inserted between arms 52 and 54, the downturned ends of arches 56 and 58 serving to guide the article to a position between said arms, and then the loop is released and by virtue of its own resiliency, returns to a closed position, illustrated in Figs. 3 and 4;.

The modification shown in Fig. 5 is identical with the structure illustrated in Figs. 1 and 2, with the exception of kinks 26 and 28. There is also a shortening of the overlapped portion of arms 18 and 20 (Figs. 1 and 2) because it is not necessary that the free ends of these arms extend to the point beyond kinks 26 and 28. The modification illustrated in Fig. 5 has the loop 80, coil 82, sides 84 and 86, shoulders 88 and 90, formed at the meeting point of sides 84 and 86 and arms 92 and 94 which, in turn, terminate in overlapping arches 96 and 98. The plane of loop is transverse to the plane of arms 92 and 94 and the operation and relation of parts found in this modification is precisely the same as that found in the preferred form illustrated in Figs. 1 and 2.

While the specific structure described and shown is important, it is understood that many modifications in constructing an attaching fixture in accordance with this invention might be made without departing from the spirit of the invention or scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

An attaching fixture formed of a single piece of material comprising an elongated body having a pair of opposed sides disposed in parallel contiguous planes; a coil formed in said body at the meeting point of said sides; a shoulder formed by each body side at the end thereof opposite said coil, said shoulders intersecting when the fixture is closed; a rebent arm extending from each shoulder respectively, said arms being in parallel, contiguous planes transverse to the plane of said body; an arch formed in each arm respectively, said arches being in opposed register when the fixture is closed; and a kink formed in each of said rebent arms between the said arch thereof and its inwardly extending end, said kinks being in the same plane as its forming arm and in opposed, spaced apart relation when said fixture is closed, said kinks being arch-shaped whereby to position the free inwardly extending end of each rebent arm respectively in register with the body of the opposite re GEORGE E.
