vireo SATES CARL F. SKOOG, OF SOUTH BEND, INDIANA.

CLINKER TONGS.

Application filed July 12,

T 0 aZZ whom it may concern:

Be it known that I, CARL F. SKooc, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented a certain new and useful Improvement in Clinker Tongs, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to clinker tongs and more particularly to a device of this character adapted for insertion through the front fire door of a furnace, etc., and adapted to be extended down into the fire box so that the co-operable fingers at the end of the tongs may be actuated to grip the clinkers so that they may be lifted out of the fire pot.

For a better understanding of my invention reference is to be had to the accompanying drawings in which Fig. 1 is a side elevation of my clinker tongs with the handle construction broken away;

Fig. 2 is a bottom view of Fig. 1; and

Fig. 3 is a sectional view along the line 3-3 of Fig. 1.

Referring more in detail to the device shown, it comprises a suitable head A hav-- ing laterally extending hook shaped fingers 56, preferably two in number, although, of course, more may be used if desired. These fingers are preferably in the form of a forked shaped extension connected at the cross piece 7. The head A is hollowed out as indicated by the dotted line 8 and has a pair of depending ears 9 between which a movable finger 10 is pivotally supported. The operating end 10 of the finger extends up into the hollow of the head and 1s pivotally connected to an operatlng rod 11 whlch extends back through the tubular handle 12. This handle is secured to the head prefera bly by threading into a neck extension 13. The head A and its integral parts are preferably constructed of cast malleable iron although, of course, not limited to this material.

An operating member is supplied in the form of a slidable sleeve or handle 14. The operating handle 14 is secured to the operating rod 11 by means of a cap 15 which threads onto the sleeve 14 and through which the rod 11 extends. The rod is secured to the cap by means of a nut 16 on the inside 1922. Serial No. 574,563.

and a nut 17 on the outside with the ring 9 and the finger 10 and clamped in position.

The operating handle 14 with its cap 15 is then slipped over the free end of the handle 12 and rod 11 against the nut 16, after which the ring 18 and nut 1'1 are put in place. The device may just as readily be taken apart.

In connection with the tubular handle 12, this of course, may be made of any desired length depending upon the use to which the device is to be put. Ordinarily a handle about twenty-four to thirty inches long will take care of the usual furnace or fire place.

This handle 12, however, may be extended into great lengths so that the tongs may be used also for removing articles from high' shelves where they may be gripped between the fingers.

In the operation of the fingers when used forremoving clinkers from the usual residential boiler or furnace, the tong head is inserted at an angle down through the fire door opening, the operator gripping the handle 12 in one hand and the operating handle with the-other and extending the fingers into their open position. The clinkers are then raked up loose by the rigid laterally extending fingers 5 after which the handle 14 is pulled outwardly thereby closing the fingers to grip the clinker so that it may be readil removed through the fire door.

What claim as new and desire to secure by United States Letters Patent is:

1. In a clinker tongs of the character described, a hollow head having a solid neck and hook shaped forked end extending laterally from one end thereof and ears de pending from an open side of the head with a threaded socket at the other end, a tubular handle extending from and threaded into the socket of the head, a laterally positioned finger extending between said ears into the head and pivoted to said cars, a rod extend ing through said handle ending in the hollow head and pivotally connected to the finger inside the head, and an operating handle for said rod 2. In a clinker tongs of the character described, a hollow head having a hook shaped finger extending laterally from one end thereof and ears depending from an open side, a tubular handle extending from the other end of the head, a laterally positioned finger extending bet-ween said ears into the head and pivoted to said ears, a rod extending through said handle into the hollow head and pivotally connected to the finger inside the head, the hollow in said head being so shaped and said ear pivots so positioned as to permit insertion and removal of the finger and attached rod through the head.

In witness whereof, I hereunto subscribe my name this sixth day of May A. D., 1922.

CARL F. SKOOG.
