To /LZZ whom 'it may concern.'
Be it known that we, JAMES J. Vnnnn'r'rn, and ALEXANDER iV. iVnrrn, subjects of the Kingdom of Great Britain, residing at Udanaln-in the county of Ashland and State of ivisconsin, have invented certain new and useful Imprm'ements in Timber-Tongs; and we 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 timber tongs and particularly to a. construction whereby the tongs are provided with a swivel connection with a cable or other supporting device.
The invention has for an object to provide a novel and improved construction of tongs wherein the angular sliding lever is provided with a bifurcated head to embrace the angle ends of the tongs jaws, together with a curved yoke having a central -aperture and pivoting ears at opposite ends for the tongs jaws.
Another and further object of the invention is to provide an improved construction of the swivel connection comprising'a head adapted to be threaded upon the end of the tongs lever and carrying an eye loosely swiveled therein. Y
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.
In the drawing:
Figure 1 is an elevation of the tongs with a portion of the yoke and lever in section;
Fig. 2 is a detail perspective of the operating lever; and
Fig. 3 a bottom plan of the yoke.
Like numerals refer to like parts in the several figures of the drawings.
The numeral 10 designates the yoke of the tongs which is preferably formed of curved construction so that the 'depending ends 11 thereof are provided with a slot 12 thus forming Lpivot ears for the jaws 13 ofthe tongs.' These jaws may be of any desired size or configuration and are pivoted within the slot 12 of the yoke ends by means of the cross bolts 14 extending between the side walls of the slot. The upper end 15 of each of the jaws 13 is disposed at an angle to the remainder of the jaw and formed with a slot 1G at its free 'end 17.
head by cross pins 21 extending between the walls of the slotted head.l The upper face of this head is curved as at 23 and'seats against the'under face of the yoke adjacent the aperture 18 therein so as to limit the inward movement of the jaws toward each other in their closing movement. The angularly disposed ends 15 'of the jaws also abut against the inner wallV 24 of the slot 22 so that when the points 25 of the tongs are firmly embedded in the timber or other niaterial and the strain is applied to the stem, these parts are braced both at the center and the ends of the yoke so that there is vpractically no danger of slipping or yielding under the lifting strain. For the purposel of providing a swivel connection for the tongs particularly when a hauling or supporting cable is used as in timber transportation, a swivel head 26 is provided.
he lower portion of this head is formed with a threaded aperture 27 to receive the threaded end 28 from the angular body 19 of the stem and if it be desired to lock these parts in their assembled relation a key 29 maybe inserted through an Yaperture in the head and a corresponding aperture 30 in the threaded end 28. This head is also pro.- vided with a central openingl adapted to receive the head 32 carried by the shank 33 of an eye-bolt 34 through which a cable is adapted tobe passed. The. shank 33 of the eye-bolt extends through an opening 35 in the head so as to provide a swivel or pivotal connection at that point by which the tongs may be swung in a rotary path or to any degree thereof necessary to permit the material carried thereby to pass other objects and also to lprevent the cable from twisting or kinkimglr as it is free to move through the eye which adjusts itself in posi'- tion.
'The operation of the invention willgbe apparent from the foregoing description from which it will be seen that the tongs are particularly adapted in timber or shipv building work and owing to their braced construction are not liable to slip when engaged with material. They tongs are alsovery powerful because the four pivotal centers are in substantially the same 'transverse line and receive the same strain on each when a load i's being carried by the tongs. It will also be noticed that the curved form of the yoke causes it to form practically a continuation of the jaw from its pivot upward to the point where the head of the stem has its bearing On theunderface of the yoke. This causes the lifting strain of the jaws to be carried'practically from the head ot' the stem, which in its movement also actuabes the swinging of the jaws.
It will be seen that the invention comprises a simple, efficient and very economical construction of tongs and onel 1n Which the swivel connection may be removed from the Slide lever and replaced by any other desired. attachment for handling the tongs.
What we claim is Tongs embodying a curved yoke having a central angular aperture, jaws p'ivoted to the ends of the yoke and having portions extending at an angle within the yoke, a stem of angular cross section sliding through said aperture and having a head within the yoke curved to lit the yoke, said head having a slot and transverse pins extending through the slot, and said portions of the jaws extending Within said slot and having slots engaging said pins.
In testimony whereof we have signed our names to this specification in the 'presence of two subscribing Witnesses;
JAMES J'AQUES VERRETTE. ALEXANDER W. VHITE.
