Application filed July 27,

7 object a separable fastener for hose supportwhich will securey latch around the leg of the wearer, and not depend upon the elastic webbing to prevent its becoming unlatched.

A further object is to construct a separable fastener for hose supporters which will allow the latch and latch plate to oscillate independently without becoming unlatched.

in the drawings,

Fig. 1 is a front elevation of my device, showing the same in latched position.

Fig. 2 is a plan view of the latch plate.

Fig. 3 is a plan view of the latch.

Fig. 4; is a side elevation of the latch.

5 is a cross section taken through the latch and latch plate, showing the same secured together.

Fig. 6 is a cross section of the latch plate taken on the line 6-6 of Fig. 1.

in carrying out my invention I employ a latch plate 7, which is preferably circular in form, and concavo-convex in cross sec tion.

The latch plate 7 is provided with parallel straight slots 8 and 9, a curved slot 10, and a latching opening 11. This latching opening has a curved wall 12, which makes the opening substantially U-shaped. The opening is provided with notches 13, adjacent its straight edge 14. In the curved slot 10 is secured a strip of elastic webbing 15. The latch 16 consists of a plate provided with curved slots 17 and 18, and with a projecting tongue 19. The forward end of this tongue 19 is wider than the rear portion of the tongue, so as to form shoulders 20. The tongue 19 is depressed or offset from the latch 16, and has its rear portion 21 curved so as to conform to the curved wall 12. Secured through the slots 8 and 9 is a strip of webbing 22. This webbing is inserted through the openings, as illus- 1922. Serial No. 577,855.

trated in Figs. 1 and 6, and to the free ends are secured the members of the hose clasp or fastener 23.

it Wlll be noted from Fig. 6 that the webhing 22 passes to the rear of the latch plate '7 and covers the latch opening 11, so that when the tongue 19 is inserted through the opening, the webbing protects the leg of the wearer from coming in contact with the tongue and consequently prevents chafing of the leg. liiiounted on the webbing is an ad'ustin slide 24. to which the free end of the webbing is attached, having been passed through the openings 17 and 18 of the latch, as illustrated in Fig. 1. The pur pose oi this adjusting slide is to adjust the webbing for the convenience of the wearer.

lily purpose in making the s ots 10,17, and 1S, curved, is that a wider webbing can be used than if the slots were straight. (Vere the slots not curved, I would either h ve to use a narrower elastic webbing for the same size of latch and'la-tch plate, or

else increase the size of the latch and latch plate.

Pl1 n 1v i119 inannei oi securing my supporter is as follows:

The webbing is first placed around the 1 i 1 h} 1d mg of tee wearer, ano t e late ie in substantially at a right ang'e to the latch plate. The tongue 19 is inserted into the opening '12 .t the P011116 where the notches 13 are formed,-the tongue fitting snugly there through. The latch is then folded. or brought down against the latch plate as in Figs. 1 and 5, and the tongue 19 slides backward until the curved shoulder 21 strikes the curved edge 12. It is now impossible for the tongue to slip out, due to the fact that the forward portion of the tongue, or that portion in front of the shoulders is wider than the opening 11,

while the notches 13 are only wideenough to take care of the thickness of material out -of which the iatch is formed, and the only way to disengage the latch is to raise it to a substantially vertical position, the same as is used for the insertion of the tongue. The curved shoulder 21, however, permits the latch to pivot or swing on the latch plate, but at the same time there is no possibility of the tongue becomingdisengaged from the slot without raising the latch as aforesaid. The webbing 22 is to the rear of the tongue 19, and prevents any possibility of rubbing theleg of the wearer.

My device is preferably constructed from celluloid, as it is not corrosive, and can be easily handled, although I may make the various parts of metal, or other suitable material.

Having fully described my invention, what I claim is:

A separable fastener comprising a non metallic circular concavo-convex latch plate provided with a centrally located U shaped opening having an outwardly extending relatively narrow notch in each of its sides adjacent its straight edge, and with straight slots parallel to each other and to the sides of the U shaped opening, and with a curved slot concentric to the periphery of the latch plate and diametricall opposite the curved end of the U shaped opening, a latch of similar material provided with concentric curved slots and with an integrally formed offset tongue, said tongue located at the edge of the latch acent the convex edges of the curved slots, the offset of said tongue being curved to conform to the curved portion of the U shaped opening, an enlargement formed on the forward portion of the tongue so as to form shoulders, said tongue and enargement adapted to be inserted through the notches of the U shaped opening of the latch plate and held in said U shaped opening by said enlargement, said latch adapted to lie on the convex face of the latch plate, the curved Offset permitting the latch to swivel freely, and the tongue to lie on the concave face of said plate and out of contact with the body of the wearer, the width of said tongue at the enlargement being greater than the length of the U shaped opening, and the width of the notches of the U shaped opening being only slightly greater than the thickness of the material of which the tongue is made, whereby remova of the tongue from the U shaped opening is permitted only through said notches and when the latch has been turned at right angles to the latch plate.

In testimony whereof, I have signed my name to this specification.

WILLIAM A. SIMMONS.
