1 Claim.

This invention relates to a cord rack latch adapted for use on electrical permanent wave machines embodying a plurality of electrical conduits (referred to in this art as cords) extending from the machine to their respective heating grids. Some permanent Wave machines embody as many as 36 cords leading from the machine, and such machines are usually provided with a rack to support the cords above the head of a customer when the machine is in use. When the permanent wave machine is not in use, the cord rack is usually moved from its raised operative position to a lower inoperative position adjacent or within the machine. It is an object of the present invention to provide a simple and inexpensive means for pivotally connecting a cord rack supporting arm to the base of a permanent Wave machine, whereby the rack supporting arm may be secured in either its operative or inoperative positions.

This invention embodies other novel features, details of construction and arrangement of parts, which are hereinafter set forth in the specification and claim and illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevational View illustrating a cord rack supporting arm pivotally connected to a permanent wave machine.

Fig. 2 is an enlarged, fragmentary sectional view illustrating the rack supporting arm mounted in upright position upon a supporting bracket Fig. 3 is an enlarged, fragmentary sectional View illustrating the rack supporting arm in its lower inoperative position.

Fig. 4 is a detail sectional View taken along the line 4 4 of Fig. 2.

Referring now to the drawing for a better understanding of this invention, a cord rack `t is secured to the outer end of a rack supporting arm 'l which has its lower end pivotally mounted upon a bracket a secured to a permanent wave machine 9. The cord rack 6 is preferably formed of wire bent to rectangular form to support a plurality of cords Il intermediate their ends. Each cord Il embodies two wires |2-l2 leading from the machine to opposite ends of an electrical resistance unit interposed in a circuit leading to a suitable source of current. The ends of the wires |2-I2 are usually connected to spring clips lll- I4 which are detachably engaged to the ends of the heater I3. 'Ihe cord rack 8 is usually secured to a collar I6 which is adjustably positioned along the outer end of the arm 1 by means of a set screw l1.

The bracket 8 is preferably formed channel- (Cl. 24S- 226) shape to provide a top flange i8, a bottom flange i9 and a connecting web 2|, the top flange Hl being formed with apertures to receive mounting screws 22. A recess 23 is cut through the web 2i and into the top and bottom flanges I8 and I0 to snugly receive the inner end of the rack supporting arm 1. The recess 23 forms abutment shoulders at 2li and 26 on the top and bottom flanges i3 and i 9, respectively, to engage the inner surface of the arm i when the latter is in its upright operative position. The arm 'l is held in engagement against the

abutment shoulders

24 and 26 by means of a pin 2l which extends through the inner end of the arm 'I and projects from opposite sides thereof for engagement against the inner surfaces of the lower flange lil and web 2i. A pair of Z-shape guide plates 28-23 are spot welded to the inner surface of the web '2l to engage and guide the ends of the pivot pin 21 during axial movement of the rack supporting arm 1. The arm 'I is movable from its upright operative position, illustrated in Fig. 1, to its inoperative position by lifting the arm Vupwardly until the lower end of the arm rises above the abutment shoulder 26 on the bottom flange t9; after which, the arm 1 may be pivoted downwardly adjacent to or Within the confines of the permanent wave machine. The arm l is moved from its inoperative position to its operative position by pivoting the arm upwardly to itsl upright position against the abutment shoulder 24 and then causing the arm to move downwardly into engagement with the abutment shoulder 26.

While this invention has been shown in but one form, it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit and scope of the claimed invention.

I claim as my invention:

In a device of the class described, a channel shaped bracket including a top flange, a bottom flange, and a connecting web, said bracket being formed with a continuous slot extending longitudinally of and through said web and normally therefrom into said top and bottom flanges to deilne top and bottom abutmentshoulders, an arm having one end portion disposed Within said slot, a pair of pivot lingers carried by and projecting outwardly from opposite sides of said arm end portion and spaced from the end thereof, guide means secured within said bracket on the opposed sides of its slot extending between said flanges and in spaced parallel relation to said Nr ortica 3 i web retaining said pivot :lingers in limited slidable and pivotal engagement therebetween, said arm end portion being adapted to be pivoted on said fingers into parallel relation to said web slot and into abutting engagement with the upper flange shoulder and then moved parallel to said web to project its lower-most free end portion into the bottom flange slot and into abutment against the shoulder thereof and the pivot lingers into abutment with the inner face of the 10 lower ilange to thereby maintain said arm in xed upright operative position, said arm being adapted to be disengaged from said upright operative position by moving it in the opposed direction parallel to said Web to withdraw its terminal 15 end portion from the lower flange slot portion and into free pivotal movement about its pivot pin.
