CANT-HOOK.

Specification of Letters Patent.

Patented June 18, 19.12:

Application filed May 14, 1910. Serial No. 561,400.

To all whom t may concern Be it known that I, JAMES H. RITTER, a citizen of the United States, residing at Topeka, in the county ofLagrange and State of Indiana, have invented certain new and useful Improvement-s in Cant-Hooks, of which the following is a specification.

This invention relates to canthooks adapted for use in handling logs, fallen trees, boxes or the like, although I wish to have it understood that there are various other uses to which the same may be put in the forni shown and in the slight modifications thereof as fairly fall within the scope of the invention as claimed.

An object of the invention is to provide a device of this character which will be composed of a small number of parts readily positioned for proper engagement with an object and with means for properly adjusting the same for different size objects.

A further object is to provide means of novel form for accomplishing such adjustment, in connection with a novel arrangement of parts included thereby.

Other objects and advant-ages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings: Figure is a side elevation of my improved device, Eig. 2 is a vertical central sectional view of a portion of a bar and the hook employed in connection therewith, Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1, looking in the direction of the arrows.

Referring to the drawings there is shown my improved device which comprises a bar 10 provided with the usual gripping head 11 and said bar is enlarged from its upper end to the lower operating portion 12, which is slightly tapered and rounded off upon its under surface toward the lower extremity thereof, thereby forming a gripping surface for objects engaged thereby.

Disposed centrally the width of the bar and extending transversely therethrough is a slot 13, the upper end of which is enlarged or tapered outwardly from a point slightly below the longtudinal center of the bar and the lower portion of the slot has its walls extending at right angles thereto, thus forming the opening at the upper side slightly wider than the opening at the lower side. Said slot also has its side and end walls 14 disposed convergingly through the bar, the lower portion thereof being restricted thereby, so as to allow greater movement longitudinally and laterally at the upper portion to a hook 15 to be hereinafter more fully described.

Extending transversely through the bar and slot therein and approximately centrally of the length of the slot, but disposed below the longitudinal center of the bar, is a pin 16 upon which said hook 15 is mounted and said pin is preferably a bolt and has upon one end thereof a securing nut 17, which is adapted to abut one side of the bar, although, if desired, I may provide such pin to be inserted without securing the same by means of the nut.

The hook 15, when in position, is adapted to coact with the engaging surface 12 of the bar in gripping objects and in order that said 'hook may be pivotally and adjustably mounted upon the pin 16 and within the slot 13, I provide the shank 18 thereof with a longitudinal slot 19 disposed adjacent to the rear edge thereof and communicating with this slot are a series of concaved notched openings 20, the upper` walls of which are extended upwardly at an angle relative to the slot 19,V so as to insure a positive gripping engagement of the same with the cross pin 16 but still allowing the shank 18, which, as will be noted is curved slightly throughout its lengt-h, to be moved laterally to disengage the pin 16 from the openings 20, so as to allow said shank to be moved or slid through the slot to adjust the hook to different size objects. As is also to be noted the openings 2O are disposed adjacent each end of the slot 19 and centrally thereof, but I wish to have it understood thatv any number of such openings may be provided according to the adjustment required and as long as the pin is free of the openings the same may be slid through the slot 19 to any desired position. The effect of the peculiar form of slot 13 is to be noted inasmuch as the upper tapered walls allow suflicient play of the shank 18, when engaging an obj ect especially in view of the fact that the pin 16 is disposed slightly below the longitudinal center of the bar and by having the slot slightly wider at its upper end than at its lower end, as more particularly shown in Fig. 3 of the drawings, it will be seen that sulieient lateral play will be given to the hook member to insure a proper gripping of the hook with objects having rectangular faces.

It will thus be seen that I have provided a very desirable and simple form of cant hook which will positively engage an object, for the purpose of handling logs and other cumbersome objects in moving them from place to place, the device being readily adjustable s0 that the hook member may be moved out of engagement with the object and in position as shown in dotted lines in Fig. 2 of the drawings, whereby the saine may be freed therefrom.

l/Vhat I claim is:

A Cant hook, comprising a handle having a slot formed therein, a hook member having a slotted shank slidably engaged in the slot of the handle, a'bolt extending transversely of the slot of the handle and slidably engaged in the slot of the shank of the hook member7 and said shank having a plurality of inclined notches formed therein at one JAMES H.
