HOISTING DEVICE Filed Aug. 18; 1954 INVENTOR.

BY W

A TTORNEY Patented Jan. 8, 1935 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to hoisting devices.

The principal object of this invention is to provide a hoisting means used manually to carry oxygen and acetylene tanks.

Another object of the device is to provide a hoist which is simple in construction and relatively low in cost of manufacture and which is safe in operation and easily adjusted to the article to be used.

A further object is to provide means for holding the tank or the like in a vertical position when the same is not being carried.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:-

Figure 1 is a perspective view of the device.

Figure 2 is a side elevation of the device holding a tank in an upright position.

Figure 3 is a modification of gripping members.

By referring to the drawing it will be seen that there is provided a pair of oppositely disposed handles 4. These handles 4 are provided with inner gripping ends 5 carrying any suitable friction material such as brake lining and the like, in order to firmly grip any article being carried, preferably of a tubular form such as a tank 6 shown in Figure 2. The handles 4 are pivotally connected to a pair of semi-circular bands 7 by means of pivot pins 8.

By referring to Figure 2 it will be seen that there is provided means for holding the tank 6 in an upright position by tilting the handles 4 downwardly so that a sharp point 9 of the handles 4 come in contact with the base upon which the tank 6 rests. It will also be seen that there is provided a pair of support legs 10 pivoted to oppositely disposed brackets 11 by means of pivot pins 12. These oppositely disposed brackets 11 are centrally located upon the semi-circular bands '7.

It will also be seen that there is provided suitable links 13 secured to the handles 4 for the purpose of providing means for attaching chains when a crane or other hoisting power is used in place of manual power. Ordinarily a tank is carried by two operators by lifting upwardly upon the handles 4, thus causing the gripping ends 5 to grip the tank 6.

By referring to Figure 3 it will be seen that there is shown a modification of the gripping means. In order to overcome difficulties such as a relatively hard or greasy surface tank it may be desirable to utilize a more positive gripping means such as lever grip members 14 pivoted to the outer ends of semi-circular bands 15 by means of pivot pins 16. It will be seen that the handles 17 are pivoted to the semi-circular bands 15 by means of pivots 18. ified form, the operators lift upon the handles 17 causing the lever grip members 14 to swing inwardly engaging a sharp gripping edge 19 against the tank to be carried. It will be seen that as the handles 17 are elevated, links 20, the upper ends 21 of which are pivoted to the handles 17 by means of pivot pins 22 while the lower ends 23 are pivoted to the outer ends 24 of the lever grip members 14 by means of pivot pins 25, will bring the lever grip members 14 up and force the sharp gripping edges 19 in gripping contact with the tank.

What I claim is:

1. In a device of the class described, a pair of oppositely disposed semi-circular bands, a pair of oppositely disposed gripping handles pivotally secured within outer ends of said oppositely disposed semi-circular bands, and support means cooperating with said gripping handles for holding a tank in an upright position when not being carried.

2. In a device of the class described, a pair of oppositely disposed semi-circular bands, a pair of oppositely disposed gripping handles pivotally secured within outer ends of said oppositely disposed semi-circular bands, and a pair of support legs cooperating with said gripping handles for holding a tank in an upright position when not being carried.

3. In a device of the class described, a pair of oppositely disposed semi-circular bands, a pair of oppositely disposed gripping handles pivotally secured within outer ends of said oppositely dis posed semi-circular bands, a pair of oppositely In operating this moddisposed bracket members secured to said oppositely disposed semi-circular bands, anda pair of oppositely disposed support legs pivoted to said brackets cooperating with said gripping handles for holding a tank in an upright position when not being carried.

4. In a device of the class described, a pair of oppositely disposed semi-circular bands, a pair of oppositely disposed gripping handles pivotally secured within outer ends of said oppositely disposed semi-circular bands, a pair of oppositely disposed bracket members secured to said oppositely disposed semi-circular bands, a pair of oppositely disposed support legs pivoted to said brackets and sharpened outer ends on said gripping handles for the purpose of holding a tank in an upright position when not being carried.
