LOAD LOCKING AND EELEASING MEANS OVERHEAD appiieaiioafuea august 15, 192i. serial no. 492,626.

To all wzlomt may concern:

`Be it known that l, JOHN Gniisivnraa citizen of the United States, residing at Estill Springs, in the county of Franklin and State of Tennessee,` have invented a new and useful Load Locking Means for Overhead Carrier following is a specification.

and Releasing s, of' which the This invention relates toload locking and releasing means for overhead carriers,` the saine being especially adapted for use in connection with trolleys or carriers employed in carrying logs,` ore,

or other materiala it being possible by a rearragement of someof the pulleys, to use the invention with trolleys or carriers of any make. i Another object is to provide means whereby by the manipulation of certain lines or cables forming a `part of the overhead carrier apparatus, the load can be easily lifted to position and secured to the carriage and subsequently releasedV and drums,

lowered. the

frictions, sheaves andllines being ree lieved of all strains and consequent wear and tear to whichthey have heretofore been sub jected while the load is being `carried from.

poi nt 'to point.

With the foregoing and other objects in view which will appear as thel description proceeds, the invention resides in the conibination and arrangement o f parts `and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, `changes in the precise embodiment of the invention shown can be ma de without departing from the spirit of the invention.

lln the accompanying drawings the preferred form of the invention has been shown. e v

ln said .drawings- Figure 1 is a side elevation carrier having the present "combined therewith".`

of an overhead improvements Figure 21s an end elevation thereofi I Figure `3 3 -s an elevation modified structure. Referring to the of a slightly figures by `characters of reference 1` designates; a supporting `cable or 'skyline oir which are mount edi the grooved wheels ofthe carriage adapted to travel l alongsaldcable. rFliese wheels are mounted between side plates 3 forming the body of bar 9 is pivotally connected to the lower or dependingk arm of the lever l and projects between superposed guide pins 10,` the two bars 7 and 9 being extended in opposite directions and outwardly beyond the plates 3. The upper or short arm of the lever 4 is connected by a link 11 to the lower or long arm of the lever 5. Latch bars 12 are pivotally connected to the lower ends of the levers 4 and 5 and extend towaid each other and formed in the lower edges of these latches are notches 13. Supporting bolts 111 connect the plates 3 and the latches normally rest on them, the grooves or. `notches in the latches serving to receive the bolts so as thus to hold said latches in proper position.

Sheaves or pulleys 15 are mounted between the plates 3 below the respective latches 12 e andanother pulley or sheave 16 is supported between the plates 3 above the link 11 but below the line 1.

The out haul line 17 is adapted to be coni nected to the bar 7 while the locking line 18 17 'is held fast and by pulling` on the line 19 the load attached thereto will be raised.

`During this action the conicalv weightwill pass` upwardly between the plates 3 and to position above the latches 12 so that these latches will thus supportthe load. @bviously as long as the carriage is being moved in either direction or while it is at rest the load will be supported. When the carriage reaches .its destination, or at any predeter- --to position under the port the load. With this construction the port, the load. Obviously by slightl mined intermediate point where it is desired to lower the load, the line 17 is held fast and the line 19 is pulled so as to lift the weight a slight distance above the latches. The loclrino` line 18 is then pulled and will cause both latches to move apart and while they are thus located the line 19 can be paid out to lower the load. It will be obvious that while the latches 12 are supporting the load the notches 13 are in engagement with the bolts 14 thereunder so that there is no danger of the latches moving apart and accidentally releasing the load as long as the weight of the load is on the latches.

Attention is called to the fact that the bar 9 is attached to its lever 4 at a greater distance from the pivot of the lever than is the bar 7 relative to the pivot 6 of the lever 5. Consequently greater power is exerted by pulling on the bar 9 than by pulling on on the bar 7 with the result that no back pull will be exerted upon the line 17 due to the moving' apart of the latches. This arrange ment also makes it easy to open the latches against the strain on the out haul line.

It has been found that the construction lcan be modified so that the load can be released without the use ot the out haul line 17 and one form of structure of this type has been illustrated in Figure 3. In this form of device the walls 21 of the carriage have opposed levers 22 and 23 fulcrumed therein and terminating at their lower ends in hooks or latchesy 24 which extend inwardly and upwardly toward each other.

A linlr 25 is pivotally connected to the upper end of lever 22 above its tulcrum and to the lever 23 below its ulcrum so that when one hoolr or latch 24 is shifted the other latch 24 will be moved in the opposite direction.

A bar 26 is attached to the carriage and to the out haul line 27 and another bar 28 is pivotally connected to the lower portion of the lever 22 and is connected to the locking line 29. A rod 30 is pivotally connected to lever 22 below its fulcrum and supports a Vcoiled spring 31 which bears against lever 22 so as to hold said lever normally pressed toward vthe lever 23. Thus when the line 32 which supports the load is moved to elevate the load, the weight 33 on the line will wedge between and move to position above the latches 24, the latches being moved apart against the action of the spring 31 which, in- `turn, will promptly shift the latches back weight 33 so as to sup weight 33 -can be bell shaped so as to house the free ends of the latches while the weight is resting on said latches. Thus the latches will be held together as long as they supraising the load and pulling on the line 29 the latches can be moved apart so as, to release the load. lVhile the part 33 has been referred to as a weight, it is to be understood that this member is primarily designed as a latch engaging means and can be oi any construction suitable for that pur Jose.

While the spring 31 has been shown with its rod 30 connected to lever 22 it will be understood of course that this spring can be located in any other place desired in older to secure the desired results.

That is claimed is l. In an overhead carrier a carriage, a load line suspended therefrom, a weight thereon, opposed latches, means for moving the latches toward or from each other into position under or to release the weight respectively, an out haul line, a connection between the out haul line and the carriage adapted when the line is pulled to move the latches toward each other, and a locking line for pulling the latches apart to release the weight and load line.

2. Inl an overhead Acarrier a carriage, spaced levers fulcrumed therein. latches pivotally connected to the respective levers and extending toward each other, a connection between the levers to insure simultaneous movement of the latches in opposite directions respectively, an out haul line connected to one of the levers to move the latches toward each other when the line is pulled, a locking line connected to one of the levers for moving the latches apart, a load line suspended from the carriage and extending between the latches, and means on the load line and movable therewith to a point above the latches for resting on the latches to support a load.
