3 Claims. 1

The present invention relates to safety appliances of the type required by workmen in building construction and operations in which scaffolding or the like is commonly used for the support of the workmen when working at more or less high levels above the level of the ground.

The principal object of the invention, therefore, is to provide a tie or anchoring device which may be employed by the workman for safety purposes, and which is adapted to be readily and conveniently secured or anchored to one of the vertical supporting ropes or cables of such scaffolding as is used in construction or building operationsand the like.

For this purpose we provide an attachment of simple construction which is adapted to be readily attached in secure holding relation to one of the vertical ropes or cables of the scaffold, and also provided with a flexible connection with suitable harness or holding means worn by the workman making use of the appliance.

It is also sought to provide an appliance of the character indicated which may be conveniently adjustable with reference to its connection with the supporting rope or cable of the scaffold and also readily detachable therefrom when not in use.

With the foregoing general objects in view the invention will now be described by reference to the accompanying drawing illustrating an appliance constructed in accordance with the purposes thereof and which has been found suitable for the embodiment of the proposed improvements, after which those features and combinations deemed to be novel and patentable will be particularly set forth and claimed.

In the drawing:

Figure 1 is a perspective view illustrating a safety appliance embodying the present invention and shown in operative position as applied to one of the supporting ropes or cables of a scaffold; and

Figure 2 is a similar view on a larger scale, showing said device and that portion of the supporting cable to which it is applied.

Referring now to the accompanying drawing in detail, this shows the improved appliance as applied to one of the supporting ropes or cables 5 of what may be referred to as a conventional form of scaffold construction (the other parts of which are not illustrated). To this cable 5 the appliance is designed to be secured or anchored by formation of a loop in the cable which is adapted to be held by a binding or frictional engagement with the device.

For this purpose the appliance comprises a metal rod or link 'I which is provided at one end with an eye or loop 8 for connection with a swivel I0 at one end of a suitable strap I2, which is provided at its other end with a link I4 for connection with a ring I5 or the like forming part of the conventional shoulder harness I6 lworn by the workman, as illustrated in Figure 1.

Adjacent to each of its ends, the link or rod 'l has rigidly secured thereto a rigid hook element I8 designed for loose hooking and detachable engagement with the adjacent portions of the cable 5, whereby the rod or link 1 may be maintained in approximately parallel relation to the cable, as illustrated.

Between its end, said link or rod 1 is bent upon itself to form an open hook portion 2Q, preferably pointing in a downward direction, or away from the adjacent end of the rod; and adjacent to said hook portion 20 the end of saidlink or rod is formed with a terminal hook 22, preferably turned in a direction for cooperating with the hook 2U for supporting and anchoring a looped portion of the rope or cable 5, as illustrated in the drawing.

The appliance is placed in its operative position as illustrated, by simply attaching both of the open hooks I8 in sliding engagement with the cable 5, and then doubling a portion of the cable between said hooks I8 to form a small loop 25 which is then swung around underneath the hook 20- and finally hooked over the top or end h'ook element 22, as shown.

By J@his means the improved appliance is rmly gripped and held against any ,downward movement on the cable 5 and therefore serves as a safe and secure anchoring means for the workmans strap connection I2 which is connected with the lower eye or loop 8 of the appliance.

Moreover the safety appliance is not only readily -and quickly applied into operative position, but may also be easily and conveniently adjusted from time to time as required to accommodate any changes in the working position of the user of the appliance.

It will therefore be apparent that a simple, inexpensive and at the same time highly eilicient .device has been devised for fulfilling the desired objects of our invention; and while we have illustrated and described what is now regarded as the preferred and most practical form of construction for embodying the features of improvement, it is desired to reserve the right to make any changes or modifications which may fairly fall Within the scope of the invention as dened by the appended claims.

What We claim is:

1. A safety appliance for attachment to scaffolding ropes or cables, comprising a rod or link provided with' a holding connection for the user of the appliance and also having means at its opposite ends fronloose detachable .engag ement With saidrope Vor cable, and intermediate hoolgV elements for detachable hooking'engagement with a, looped portion of said rope or cable of the scaffolding.

'supporting ropes or cables of scaffolding or the Y g like, comprising a rod having a holding connection for theuser of the appliance andalso means for hookingdetachably in engagement with spaced points on said rope or cable, the intermediate .portion of said rod being bent upon itself to form an open hook for engagement with a looped 2. A safety appliance for attachment@to:,.the.,, A,

supporting ropes or cables of sca'olding on the like, comprising a rod or link provided-'ai holding connection for the user of the appliance' and ralso with terminal hookingmeans. fordetach-- able engagement With said rope or cableth'e, intermediate portion of said rod or link having portionzof said rope or cable, said rod terminating adjacent ,to said open h'ook in an oppositelyk turnedY hook for holding engagement with said looped'v4 portion of the supporting rope or cable.
