LQAD BINDER.

j Application med July 2,

. extendin around a load can be tightened.

One o the objects of the invention is to provide a load binder which can be subjected to excessive strains without danger of separating the parts. Another object is to provide a load binder which is simple, durable and compact, is formed of but few parts and can be assembled readily.

A further object is to provide a load binder having bearing members of peculiar configuration which operate to prevent spreading of the tool While in use.

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 may be made v within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has lbeen shown.

In said drawings Figure 1 is a side elevation of the load binder.

Fig. 2 is a plan viewthereof showing, by broken lines, the manner in which the same will ordinarily spread when -subjected to excessive strain.

Fig. 3 is an enlarged view partly in plan and artly in section of a portion of the load inder.

,Refeiring to the figuresby characters of reference 1 designates a crooked or angle lever, one end ortion of which is forked as shown at 2 while the other end portion constitutes ay handle 3. A link 4 is pivotally mounted Within the forked end portion of the lever, it being connected to the angle portion of said lever preferably by means of a rivet 5. This link 4-has an eye 6 in its outer end" which can be swiveled therein 1924. Serial I0. 793,774.

and to the eye is connected a. link 7 which engages a hook 8. `The free end ofthe forked portion of the lever is provided with laterally extending studs 9. As shown particularly in Fig. 3 these studs 'are tapered inwardly toward their bases. The said studs project through openings 10 formed in the sides of a yoke or clevis 11. This yoke is so proportioned as to straddle the forked portion of lever ,1 when said lever is in load binding position. An eye 12 can be swiveled or otherwise connected to the yoke and may be connected by. a link 13 to a hook 14. In using the device herein described the handle 3 of the lever is swung approximately to the position shown by broken lines in Fig. lso that the link 4 and its hook 8 will thus be removed from the yoke 11 and its hook 14. The two hooks 8 and 14 can then be placed in engagement with links of a chain or other flexible element that has been extended around a load to be tied or bound. After the parts have thus been placed the lever is swung in the direction indicated by the arrow in Fig. 1 so that the forked end thereof will swing into the yoke 11 and bring the pivot 5 pastthe dead center. The pull due to the tension of the tight chain or other iexible element will tend to keep the lever ressed against the crown portion of the yo e as shown in Fig. 1 and it will not be possible to loosen the load without pulling the handle 3 so as to move pivot 5 past the dead center. Obviously by prov1ding a structure such as described, the same is rendered self-locking.

A load binder such as has been described is usually employed where it is desired to bind loads of heavy materials such as iron pipes, telegraph poles, lumber, etc., and for the purpose of lifting extremely heavy loads. It has been found 1n ractice that should cylindrical bearing stu s be rovided upon the sides of the forked lever or engagement by the clevis 11, the tool, when subjected to an excessive load or strain will tend to s read at the forked end of the lever as s own by broken lines in Fig. 2, this being due to the tendenc of the yoke or clevis 11 to work outward y along the cylindrical studs toward the ends thereof. B actual test a tool using cylindrical studs, w en lsubjected to an excessive load, is spread both at the yoke or clevis. 11 and the forked end of the lever,and the naturai tendency of the parts when thus spread is to separate.

Thel inwardly tapered studs 9 have been devised as a means for preventing this spreading action of the tool. By tapering these studs inwardly toward their bases, the increasing strain to which the tool is subjected while a load is being lifted or bound, will tend to crowd or defiect the ends of the yoke or clevis 11 inwardly toward the forked end of the lever and not outwardly away from said end. Consequently the danger of the tool spreading under the conditions mentioned is positively eliminated and a more durable and eiicient device is provided than could otherwise be obtained.

What is claimed is l. A load binder including a lever having a crooked or angle end port/ion forked, a link'pivotally mounted in the angle portion of the forked end, bearing lugs extending outwardly from the sides of the forked end of the lever adjacent the free ends thereof, said lugs being tapered inwardly toward their bases, and a clevis pivotally mountedupon the studs and adapted to straddle the crooked or angle portion of the lever when the 'connection between the link and lever'is moved past a dead center.

2. A load binder including a leverhaving a forked angle end portion, laterally extending studs upon the free end of said forked portion, said studs being tapered inwardly toward their bases, a link pivotally mounted within the angle portion of the forked lever, a yoke adapted to straddle said angle portion and having eyes for receiving the tapered studs,- said studs and yoke cooperating when the .binder is subjected to strain, to draw-f the eyes of the yoke toward each other andi toward the sides of the lever.

3'A load binder including a lever having a forked end, said end being crooked to rovide an angle portion, laterally exten ing studs upon the free end of the forked portion of the lever, said studs being tapered inwardly toward their bases, a link pivotally mounted within the forked portion of the lever at the angle thereof, a yoke pivotally mounted on the studs and adapted to straddle the slotted portion of the lever with the point of connection between the link and lever ast the dead center, and means connecte to the link and yoke respectively for engagin op osed portions of a tie device, to bin a oad, said yoke and the tapered studs cooperating when the load binder is subjected to strain, to prevent spreading of the yoke and lever.

4., A load binder including a lever with a forked end, saidend being crooked to provide an angle portion, a yoke pivotally connected to the free end of the forked portion of the lever, a link pivotally mounted within and connected to the angle portion of the lever, means connected to the yoke and link respectively for engaging opposed portions of a load tying element, said lever being mounted to' swing into the. yoke about its points of connection with the yoke to bring the point of connection between the lever'and link past the dead center, and cooperating means upon the yoke and lever for deflectinfr the ends of the yoke inwardly toward the lever when the binder is subjected to excessive strain.
