Sept. 15, 1931. .1. G. HALL ETAL CLINKER TONGS Filed April l1, 1930 JOHN 6. V4/ L Patented Sept. 15, 1931 PATENT FFICE JOHN Gr. HALL AND CARL It. HALL, OF CHICAGO, ILLINOIS CLINKER TONGS Application led April 11,

rlhis invention relates to improvements in clinker tongs, and has for one of its principal objects the provision of a tongs or similar device for removing clinkers and like objects from furnaces, stoves or other heating plants.

One of the important objects of this invention is to provide in a clinker tongs, means for readily grasping and removing clinkers and other hot objects from a furnace or the like without danger or injury to the hands of the operator, while at the same time providing a positive acting device, and one which will securely grasp the clinker, so there will be no danger of droppingit back into the fire box or upon the feet or other portions of the anatomy of the operator.

Another and still further important object of the invention is to provide in a clinker tongs a. pair of unitary resilient arms which are normally impelled toward each other by the inherent spring action of the tongs themselves and which arms have at their ends coacting clinker grasping elements which are offset with relation to each other in two or more planes, whereby a positive action will result.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described.

in. the drawings:

Figure l is a side elevation of the improved clinker tongs of this invention.

Figure 2 is an end view of the same, illustra-ting particularly the offset relationship of the clinker grasping arms.

Figure 3 is a detail view of one of the arm ends, illustrating a slight modification.

Figure 4 is a side view of the arm end shown in Figure 3.

Figure 5 is a perspective view illustrating a modified form of clamping element.

As shown in the drawings:

The reference numerals 10 and 12 indicate respectively the'arms of the improved clinker tongs of this invention, the arms being formed of a unitary bar of resilient metal 1930. Serial No. 443,474.

having a spring loop 14 at their doubledover ends, this spring loop acting to bring the grasping ends 16 and 18 respectively of the arms together in clinker-holding relationship whenin normal position.

From an inspection of Figure 1 of the drawings, it will be noted that the arms 10 and 12 are, crossed adjacent the points where they are lfashioned into the grasping ends and that these grasping ends themselves have a series of integral humps or bends therein which overlap slightly at two or more points when viewed in a horizontal plane.

On the other hand, when the arms are viewed in a vertical plane, itwill be seen that the grasping end 16 of the arm 10 is curved outwardly from the corresponding portion y of the grasping end 18 of the arm 12, thereby providing a space between these arms, which space is irregularly shaped and accordingly, adapted to fit itself to more or less degree with respect to the contour of an ordinary clinker or the like.

In Figures 3 and 4 is illustrated a slight modification of the invention whereby each one of the grasping ends of the arms is fashioned with integral curves or bends as shown at 20, and furthermore, the same is fashioned to provide an additional grasping surface, portions of this fashioned element being punched out and bent inwardly as shown at 22 to provide points which penetrate more or less into the bodyof the clinker or other element which is to be withdrawn from the fire or handled in some other way by the tongs.

As shown in Figure 5, a still further modification of one of the grasping arms is provided, the same being formed in a quite broad or flat member 24 which has integral lbends or curves `therein and which also has portions thereof cut away and bent inwardly as at 26 to form clinker grasping and supporting lugs. Y Y

It will be evident that herein is provided a clinker tongs or similar element which will positively grasp and securely retain a clinker or other object, particularly when it is desired to withdraw the same from a hot fire or the like. The constriction and operation of the device is quite simple, and there-is nothing to get out of order or cause diioulty in operation. The spring action of the handle construction insures a positive gripping contact With the clinker itself, and in this Way, accidental dropping and subsequent damage is avoided.

7e are aware thatmany changes may be.

made and. numerous' details of construction varied throughout a Wide range Without departing from the principles of this invention, and We, therefore, do not purpose Vlimiting the patent granted hereon otherwise than as necessitated by the prior art.

We claim as our invention.:

A clinker tongs, including in combination, a pair of joined integral arms, a resilient loop formed at the' juncture of the arms and elinker grasping` ends Vat the outer portions of the' arms, said'clinker grasping ends comprising lntegral extensions ofthe arms being provided. With integral bends and humps, and 1n- Wardly turned clinker supporting elementsY onthe. ends, said elements comprising integral. lugs,A partially cutv away rom'the bodyv Y ofthe armv end..

In testimony whereof We aiix our signatures;

JOHN G. HALL. CARL R. HALL.
