Large stones are hand'lcddn the stone working plantsby means of supporting slings made of rope. These are open to several objections. In the first place the hard twisted rope presents only a small surface to the stone for gripping and holding it. Necessarily whererit passes around the corners or edges the pressure due to the Weight of the stone is all concentrated at a few ithey ar neecled. lhe rope also gets watersoaked around -the polishing .bins which imakes at --har.d .to -=ha'ndle. It is practically f in possibleto clean stain from it and the g-rit which collects uponit. Therope on account bf itscircularshapein cross scction is apt .to qpinchthe-li i 1ge rs ofthe operators and causes isomeaccidents in that way. 'As stated above the principal objects of the invention are-to avoid these di-flieu'lties.

Inits preferred form the sling is made of longpiece 10 of rubber belting of a consider able Width. I prefer to use rubber belting which comprises canvas or other textile material coated and saturated with rubber. lhisniaterial is not stretchable but its entire surface is covered with rubber. I It is-not absorbent and its surface can be cleaned readily. Thisis fastened at one end to a leather loop ll'by riveting-it or otherwise perina- Y.

nentlysecuring it thereto. The other end of the rubber belt is slit longitudinally and centrally quite adistance from the end to Tforin two diverging ends 12. These are connected to a wood bar 13. This bar isfprovided with"twolongitudinal slits 14 at oppo site ends. Each of the belt ends 12 isinsert :ed in oneof these slits so as to extend through the Wood-bar and then rivets 15 are inserted throughthe ends of the Wood bar to secure the twoends together over and around the belt. 5 This belt isthen split through the cen- .ter parallel With its fiat surfaces to form twotip ends 16 which are bent back over-the ends- 0f the-Wood ban-and over the rivet -heads and clear over to the back side Where they are tacked at 17 to the edge of the Wood bar. This completes the construction as shovvn in. Fig.3 leaving a space 20 between the tv'vo belt ends. I

In the use of the device, the Wood bar is placed on the top of the stone to be handled and the two ends 12 of the belt dropped down from the top around and under it so that the loop end 11 can be brought up over the back of the stone to the top and under the Wood bar 13 through the space 20 as iii) shown in Figs. 1 and 2. This leather loop is supported and carried by the usual hook.

The manufacture of the slings has been described and its use is thought to be clearly. obvious from the description and drawings. It will be readily understood also that with the use of a sling of this character there is no danger of injuring the edges of the blocks by the pressure due to its weight as there is a wide surface of contact at each corner of the sling passing over the edge. This entirely eliminates the use of blocks which have been put around the edges of the stone heretofore to prevent their being broken. This sling is durable and easily cleaned. The grit that accumulates on it and the stain that it may receive are taken off very easily so that the stone will not be marred or dis colored by it. The stone can be handled around the plant in almost any way and is safe from injury by its contact with the sling or any part of it. Its use also tends to reduce accidents because there is practically no chance of any person around the plant getting his finger pinched in this close fitting arrangement on account of its WlClfl contact and close fitting qualities.

It will be understood that although I have described the belt as bein of rubber and I b n preferably use a rubber belting, I can use a leather strip, preferably a piece of leather belting made of the same design.

Although I have illustrated and described only a single form of the invention and mentioned only two materials for the main part of the sling, I am aware of the fact that other modifications can be made therein by any person skilled in the art withoutprising a wide belt of material with a soft surface having-a loop end and adapted to be placed around the stone, said belt being slit longitudinally at the other end to provide two integral diverging ends, and a bar arranged crosswise and lined to said ends,

the ends being separated enough to permit the loop end of the sling to pass under the bar through the space between them for the purpose described. I

2. As an article of manufacture, a sling for handling and turning stone comprising a piece of rubber belting, 6. lo p attached to one end for supporting the sling, said belting being slit longitudinally and centrally for a distance in from its opposite end and the two ends thus produced being separated from each other, and a barlocated transversely at the end of the sling and provided with slits therethrough at its opposite ends through which the two separated ends of r the belting are placed and secured leaving a space between the two rubber belt ends through which the loops end can be passed under the bar.

3. As an article, of manufacture, a sling for handling and turning stone comprising a piece of rubber belting, a loop attached to one end for supporting the sling, said belting being slit longitudinally and centrally for a distance in from its opposite end and the two ends thus produced being separated from each other, a wooden bar located transversely at the end of the sling and provided with central slits therethrough at its opposite ends through which the two separated ends of the belting are placed and riveted to provide for securely attaching them thereto, the two ends of the rubber belting passing through the wood bar being split centrally in a plane parallel to their flat surfaces to provide two tips and these tips being bent around over the ends of the wood bar and secured to the opposite or rear edges thereof to cover the rivet heads. I

4:. its an article of manufacture, a sling for handling and turning stone comprising a piece of rubber belting, a loop attached to one end for supporting the sling, a wooden bar located transversely at the end of the sling and provided with a slit therethrorwh at its end through which the end of t 1e belting is placed and riveted to provide for securely attaching it thereto, the end of the rubber belting passing through the wood bar being split centrally in a plane parallel to its flat surfaces to provide two tips and these tips being bent around. over the end of the wood bar and secured to the opposite or rear edge thereof to cover the rivet heads.

As an articleof'manufacture, a sling for handling stone coi'nprising awvide flat belt located in direct contact with the stone all around it and all the way across the belt, and having a non-absorptive surface that can be cleaned readily and consisting of a single integral piece having two branches at one end separated from each other.

In testimony whereof I have hereunto afiixed my signature,
