SAFETY REMOVABLE FASTENER Filed March 19. 1952 INVENT OR firakarfl Babel BY 1 l I ATTORN Patented Mar. 7, 1933 UNITED STATES ABRAHAM BEIBEL, OF NEW YORK, N. Y.

SAFETY REMOVABLE FASTENER Application filed March 19, 1982. Serial No. 599,889.

This application is an improvement on my application Serial No. 578,268 and now Patent Number 1,856,843, filed on December 1st, 1931 and entitled Safety removable hook fastener slide This invention relates particularly to new and useful improvements in a safety hook fastener.

. The invention has for an object the conostruction of a safetyhook fastener which is characterized bythe provision of a control slide equipped with a handle piece adapted to assume a latched inoperative position.

The invention has for a still further object the arrangement of means upon the handle adapted to frictionally engage portions of the control slide for accomplishing holding of the handle in the inoperative position. I The invention has for another object the arrangement of coacting means on the handle and the slide so that the parts may assume an inoperative position without resorting to friction.

Particularly, it is proposed to provide a re- 26 silient construction to resiliently hold the handle in the inoperative position.

Furthermore, it is contemplated to arrange theresilient structure in a manner so that the removal of the handle is possible whenever desired.

The invention has for a still further object the construction of a devicev of the class described which is of simple, durableconstruc tion, dependable in use and efficient in action,

and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention aremore particularly set forth. v

In" the accompanying drawing forming a material part of this invention:

1 is a plan view of a device constructed according to this invention.

Fig. 2 is a side elevational View of Fig. 1.

Fig. 3 is a bottom elevational view.

Fig. 4 is a View similar to Fig. 1 but illustrating a modified arrangement.

Fig. 5 is a side elevational view of Fig. 4.

Fig. 6 is a bottom elevational view of Fig. 4.

Fig. 7 is a sectional view taken on the line 77 of Fig. 5.

The safety hook, according to this invention, comprises upper and lower spaced

trapezoidal guide plates

10 and 11 respectively having their edges 12 turned intowards each other. A separation post 13 is substantially of triangular shape and interposed between the

guide plates

10 and 11 at the latch ends thereof so as to form passages adapted to engage and disengage the hooks of a hook fastening device. A rivet 14 engages through the

guide plates

10 and 11 and the post 13 to hold the parts firmly together.

The guide post 13 projects slightly from the rear edge of the trapezoidal plates and the plates at that area have small projections 15 extending over the post as clearly shown on the drawing. The top guide plate 10 is provided with a strap 16 which extends from the front to the rear. A handle 17 is formed with inturned directed prongs 18 engaging beneath the strap 16 so that it may be drawn to any position along the strap. Dot and dash lines 17 in Fig. 2 indicate a released position of the handle.

A pair of pegs 19 project from the handle 17 and are arranged so as to engage in the corners formed by the edges of the trapezoidal guide plate and the projection 15. This is clearly shown in Fig. 3. It is contemplated that the frictional resistance between the projection and the guide'plate will serveto hold the handle latched in this particular position. Thus, the handle will not flap loose- 1y back and forth during use of the article upon which the fastener is engaged.

. In the modified form of the invention illustrated in Figs. 4.7 inclusive, provision has been made to positively hold the handle in the inoperative position instead of depending upon friction. More particularly, each of the pegs 19 are formed with notches 20 so that they simulate hooks and may engage upon "the edge of the trapezoidal plate 10. A spring 21 is secured upon the end of the 100 1 may slip past so that the handle is completely removed. A stiff resilient spring 23 is mounted between the reduced end of the strap 16 and the spring 21 and serves normally to close the openings 22 through which the prongs 18 may pass. The arrangement allows the handle 17 to be pulled so that the spring 21 is flat against the spring 23 and in this position the pegs 19 may have their notches receive the edge of the plate 10. If it is desired to remove the handle 17 it is merely necessary to pull quite strongly upon the handle so that the spring 23 also bends whereupon the handle comes out.

In operation the control slide is engaged upon rows of hook fasteners and is adapted to lock and unlock the hooks thereof as it is moved in one position or the other. When the control slide is not used the handle should be latched so that it does not move around freely.

.While I have shown and described the preferred embodiment of my invention, it is to be understood that l do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. A safety hook fastener, comprising upper and lower spaced trapezoidal guide plates, a separation post between said guide plates rigidly connected therewith, a strap across the top guide plate, a handle with prongs extending beneath opposite edges of the strap, pegs projecting from said handle and positioned thereon to engage against one edge of one of the guide plates to hold the handle against free moving, and a resilient element interposed between one end of said strap and prongs to force the pegs against the edge of said guide plate.

2. A safety hook fastener, comprising upper and lower spaced trapezoidal guide plates, a separation post between said guide plates rigidly connected therewith, a strap across the top guide plate, a handle with prongs extending beneath opposite edges of the strap, pegs projecting from said handle and positioned thereon to engage against one edge of one of the guide plates to hold the handle rea ies against free moving, said strap formed with cut outs and which ordinarily allow the prongs to slip past, and a flat spring mounted on the strap and across the cut outs for normally holding the prongs within the boundaries of the strap.

3.
