\ tul Improvements in Trip-Hooks; and I do hereby declare the following to be a full,
' clear, and exact description of the invention,
such as Will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in I trig hooks.
ne object of the invention is to provide a trip hook of novel and simple construction, particularly adapted for releasing a trip chain, which is under a heavy load or strain.
Another object is to provide a device of this character which will efiectively hold the chain against movement under normal working conditions, but which can be quickly and easily released to free thechain.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
Tnthe drawing: Figure 1 is an elevatlon of my device; Fig. 2'is a top plan view; Fig; 3 is a vertical transverse section on the line 33'of Fig. 1; and 4 is a longitudinal section on the line H of Fig. 2.
Referring particularly" to the accompanying drawing, 10 represents a tubular memher, in which is disposed a longitudinally slidable pin 11. 0n this pin, intermediate its length, and within the tubularmember, is formed a circumferential flange or shoulder 12. On the outer end of the tubular member is detachably engaged a hollow screw threaded cap 13 which is adapted to be engaged by the shoulder of the pin to limit the outward movement of said pin. To the outer end of this pin is secured a small chain or rope 14: by means of which the pin is moved outwardly, or rearwardly in the tubular member. Formed on the lower side of the tubular member is a web 15, the same extending beyond the inner end Wall of the tubular member 10is an open ing 18, in the inner portion of which is disposed a small pin 19, behind which is arran ed a coil spring 20. This spring is held un er tension against the inner end of the pin 19 by an adjustable screw 21 engaged in the outer end of the said opening 18. On the pin 11, outwardly of the shoulder is a circumferentialgroove 22, into which the @5 when the pin or bolt 11 isdisposed with its 7 inner end of the pin 19 is adapted to snap inner end in the opening 17.
The chain 23 is passed through the openi'ng between the end 16 and theadjacent end of the cylindrical member, with the pin 11 engaged in the opening 17. The pin may be engaged through a link of the chain, or one of the links placed between the rib and the pin 11, so that the links attached to either end of the said link will prevent movement of the chain in either direction. The pin 19 engages in the groove of the pin 11 and holds the said pin from disengagement. When it is desired to release the chain, the small chain or rope is iven a sudden or quick jerk, which will withdraw the pin 11, and release the same from the pin 19,thus permitting the chain to pass freely from the device.
It will thus be seen that the device is' extremely simple and cheap in construction, as well as eiiicient in operation, and that the pin-l1 can be quickly and easily re,-
leased even when a great load or strain is on the chain.
What is claimed is:
1. A releasing device for a trip chain comprising a tubular member having a web formed on one side thereof and extending longitudinally beyond the end of the tubularmember and having its end turned angularly to a point opposite the adjacent end of the tubular member, said end having an opening formed in alinement with the tubular'member, a spring-pressed pin disposed through the web and extending into the tubular member, and a slidable pin disposed through the tubular-member and formed with a circumferential groove'ior the re-. ception of said spring pressed pin.
2. A releasing device for a trip chain comprising a tubular member having a web formed on one sidethereof and extending longitudinally beyond the end of the tubular member, said web being extendedforwardly and upwardly to provide a hook "formed with an opening in alinement with the tubular member, the opening in the forward end of the tubular member being reduced to provide a stop shoulder, the opposite end of said member being closed by a screw cap, a 'slidable in having 'a stop shoulder and a circum erential" groove in front thereof mounted for through the tubular member, the forward movement end of said pin being adapted to normally 10 engage Within the opening of the said hook,
anda spring pressed pin disposed through the web and extending into engagement with the circumferential groove of the slidable pin.
