ALFRED X. MILLER, OF MARINETTE, WISCONSIN.

LOG-CHAIN.

Specification of Letters Patent.

Patented Julie 6, 19 il Application filed April 28, 1910. Serial No. 558,249.

To all whom 'it may concern:

Be it known that I, ALFRED X. MILLER, a citizen of the United States, residing at Marinette, in the county of Marinette and State of Wisconsin, have invented certain new and useful Improvements in Log- Chains, of which the following is a speci cation.

This invention relates to trip hooks for7 logging chains and has for its object the provision of a comparatively simple and thoroughly efficient device of this character, by means of which a chain or other flexible binding element may be securely fastened around a number of logs or other load so as to prevent accidental separation thereof during transportation or shipment.

A further object is to provide a trip hook, the construction of which is such that the same may be used as a chain tightener.

A further object is to provide a hook having a binding chain secured to one end thereof and provided with a trip link adapted to embrace the shank' of said hook, means being provided for tripping the link, thereby to release the hookwhen it is desired to dump the load of logs.

A still further object of the invention is generally to improve this class of devices, so as to increase their utility, durability and eiliciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of const-ruction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a trip hook constructed in accordance with my invention, showing the same in position on a load of logs, the shank .of the lever being in position to be swung downwardly for engagement with the trip link; Fig. 2 is a similar view, showing the trip link in engagement with the shank of the hook; Fig. 3 is a perspective view o f'one of the hooks sho-wing the binding element attached thereto.

Corresponding and like parts are-referred to in the following description and indicated in all the views of the drawings by the same reference characters.

yaround a load of logs,

duce an intermediate slot 9 for engagement Y with one of the links of a chain or other binding element, indicated at 10. The head 6 isv provided with a lateral enlargement 11 having an opening 12 formed therein and preferably disposed slightly7 above the closed end of the slot 9 for engagement with a portion of the binding element or chain 10. Secured to the chain 10V is a trip link 1l adapted to embrace the shank 8 of the hook when the latter is swung downwardly to the position shown in Fig. 2 of the drawings, thus to hold the hook against tilting movement. The lower end of the shank 8 is provided with an offset portion 15 which serves to assist in preventing accidental. displacement of the link 14, there being an opening 16 formed in the shank opposite ythe offset portion 15 thereof for the reception o a locking key 17 The locking key 17 is preferably formed from a single length of spring wire, one end of which is bent to produce a coil, while the other end thereof is formedwith an eye 18 for engagement with the adjacent end of a short chain sect-ion 19, the other end of the chain 19 being 'secured to one of the links of the chain 10, as best shown in Fig. 3 of the drawings.

-In operation, the chain 10 is passed indicated at 21 and the shank 8 of the hook grasped in the right hand and said hook moved upwardly until the bill thereof engages one of the links of the binding element, said link being inserted in the slot 9, as best shown in Fig. 1 of the drawings. lThe operator then exerts a downward pressure on the shank S which causes lthe lower lor perforated end of the shank to assume a position substantially parallel with one end of the chain 10,' and atthe same time exert a longitudinal pull on the other end thereof so as to tighten the chain and cause said chain tov eifectually grip the load of logs. The trip link 14 is then passed over the free end of the shank 8, after which the locking key 17 is introduced in the opening 1G and in which position, the hook will be securely held against tilting movement during transportation or shipment of the logs, as best shown in Fig.

2 "of the drawings. In order to dump the logs, it is merely necessary to detach the key 17 from the opening 16 in the shank of the hook and place the hooked end of an ordinary trip chainj around the shank 8 or against the' link-'111i and exert a slight longitudinal pull thereon which 4disengages thel trip link lelfroin said shank and causes the llatter to move upwardly in the arcof a circle,fso as to cause the chain l0 to slip out of 'the slot 9,- thusreleasing the logs and allowing the same v-to be deposited on the ground. y

-I Attention ishere called'to the fact that the opening lf'is4 disposed in a plane slightly above the closed end of the slot 9 so as to insurea trip action of the hook 5, while the offset portion or enlargement on the shank,

by engagement with thevlink' 14:, serves to vprevent said linkfrom slipping' longitudinaliy on the shank of the hook when 'fthe locking key 17 is detached and until a slight downward ressure is exerted on said link 4 by means o the chain 20. Such a construction prevents `premature release of` the hook when theoperator removes the key 17 so as 'effectually'to prevent the logs from falling on the operator when' walking around `the load preparatory to Ldumping the same. It willrozt course be understood that the binding eiementmay be made iny one or more "sections, the mainobject of the device being element together so as'to to draw the adjacent ends of said "binding A prevent accidental displacement of the load.

Having thus described the invention, what is claimed as new is: v l. A device of the class described includingf abi-riding element, a hook secured to one portion of thebinding element and adapted to engage another portion "thereof, a vlink carried by said binding element and adapted tov embrace the shank of the hook, and a locking key extended through the free endl of the shank beneath the link for preventing accidental displacement of said link.

2. A device of the ciass described includi ing a binding Chain, a .hook secured to one portion of the chain and provided-1 with a slot adapted to receive one of the links of said chain, a trip link carried by the chain and Vadapted to embrace the shank of thej hook,"a-nd a locking key engaging the lower end of the shank. t 1 I device of the class described including abinding chain, a hook secured to one portion of the chain and provided with a bill spaced from the. shank of the hook to form a slottor engagement with one of the links of said chain, therebeing an enlargement formed on the shank oi the hook, a trip linkcarried by the-chain and adapted to embrace the shank of the hook at said enlargement, and a 'locking member extending transversely through an opening in the shank oit" the hook at said enlargement.

4. A device .pf the class described-including a binding chain, a hook having-an enlarged head provided with anopeninglfor the reception ot'. one of the links of the binding chain and having its bill spaced from the shank of the hook to form a slot for engagement with another link of said binding chain, the opening in the headbeing disposed in a plane above the-closed end of the slot, there being an enlargement formed on one lside of the shankof the hook at the lower end thereof, a trip link carriedy by the binding chain and Iadapted to embrace the shank of the hook at said enlargement., a locking key extending through the opening` in the shank of the hook at the enlargement, and a connection betweenthe locking key and the binding chain.,`
