LAZY-TONGS CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 732,418, dated June 30, 1903.

Application filed February 20,1903, Serial No. 144.304. (No model.)

To all whom/it may concern.-

Be it known that I, FRANK KING, of Indian-f apolis, county of Marion, and State of Indiana, have invented a certain new and useful Lazy-Tongs Construction; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

This invention relates to a lazy-tongs construction wherein four lazy-tongs are combined in a rectangular construction with their adjacent corners pivotally connected with each other, whereby a solidconstruction is made. The solidity of this construction arises from joining the lateral edges or corners of the lazy-tongs on the four sides of a square, whereby a four-sided continuouslyeconnected lazy-tongs is provided.

The full nature of this invention will be understood from the accompanying drawings and the following descriptionand claims.

In the drawings, Figure l is an elevation of the apparatus looking at one corner of a'rectangular construction and with the lazy-tongs partially operated. Fig. 2 is a section on the line 2 2 of Fig. 1, showing especially the means for actuating the lazy-tongs. Fig. 3 is a section on the line 3 3 of Fig. 1, showing in detail the joint between the lateral edges or corners of two lazy-tongs In the first place four lazy-tongs of ordinary type are made consisting of the bars 10, crossing each other centrally and pivoted at 11. There is one of these lazy-tongs on each side of the square, as shown in 2, and the lateral edges are pivotally connected, as shown in Fig. 3. A stirrup 13 envelops and is pivotally connected with the two slats at one corner of one of the lazy-tongs by the bolt 14. l A bolt 15 passes through the two slats 10 of the adjacent lazy-tongs and said bolt is swiveled in the end of the stirrup 13. This permits the two lazy-tongs thus joined to be elevated or depressed simultaneously and it holds the two lazy-tongs strongly together.

The lower bars 10 of. each pair of lazy-tongs is pivoted to a block 16 at the four angles or corners of the lazy-tongs construction. Said I block has upwardly-extending cars 17, and a bolt '18 passes through said ears and the lower end of the lower slat 10 of the lazy-tongs. Said blocks 16 have an opening through them threaded, and they fit on the threaded shafts 19, which at one end have bearings in the cornersat 20 of the base-frame 21 and at the other end are mounted in the bearings 22, which are secured upon a circular base-plate 23 and carry on their inner'ends abevel-gear 24. Hence there are four of the blocks 16 and four of the threaded-shafts 19 and four of the bevel-gears 24 at right angles to each other. The four bevel-gears mesh with a large bevel-gear 25, that is horizontally mounted on a circular base-plate 23, so that any rotation of said large bevel-gear 25 would rotate all the small bevel-gears 24:. The large bevelgear is rotated by the bevel-pinions 26 on the ends of the shafts 27, that are mounted in the bearings 28. and the sides of the frame 21 and carry on their outer ends cranks or handles 29. A cross-board 30 and diagonal guideboards 31 extend along the under side of the apparatus for reinforcing the parts.

When the large gear 25 is rotated by the handles 29, it will cause all of the blocks 16 to simultaneously move inward or outward. The duplicated parts are all made alike, so that the extent of such movement of the blocks 16 will always be equal and uniform. As the blocks 16 are drawn inward by the shafts 19 the rectangular lazy-tongs construction will move upward and the reverse movement of the blocks 16 will cause it to move downward and it can be brought down to a very compact form.

Anything may be placed upon the upper end of the lazy-tongs construction according to the use contemplated. I have shown here a platform 32, with downwardly-extending ears 33, to which four bars 34 are pivoted, one on each side, and these bars 34 at their lower ends are pivotally connected with the bolts 11 by a stirrup (like 13) exactly likethat shownin Fig. 2. The Vertical movement of the lazy-ton gs construction will increase or diminish its width, and consequently the lower ends of the suptongs, threaded shafts extending through saidblocks in line with a central point between said blocks, gear-wheels secured on the inner ends of said threaded shafts, and a rotary gear-wheel that meshes with all of said gearwheels for actuating them.

2. An apparatus comprising, a plurality of 20 lazy-tongs placed with their lateral edges respectively adjacent each other, pivotal connections between the adj acentedges orcorners of said lazy-tongs, a threaded block pivotally connected at each corner of the construction at the lowerend with the two adjacent lazytongs, threaded shafts extending through said blocks in line with a central point between said blocks, gear-wheels secured on the inner ends of said threaded shafts, a rotary gearwheel that meshes with all of said gear-wheels for actuating them, and a crank-shaft with a pinion on one end to actuate said large gearwheel.

In witness whereof I have hereunto affixed my signature in the presence of the witnesses herein named.

FRANK KING.
