APPARATUS FOR TREATING TIMBER.

Application inea' February 2o, 1917.

To all wwm it may concern.-

e it known that I, ERNEST F. HART- MANN, a citizen of the United States, residing at T e present invention paratus for treating timbers with a suita le wood ter and of irregular contour. The present have devised novel and improved means forhermeticallv joint between the the sides ot the pile.

luther objects ot' the invention will become apparent from tion when take-n in connection with the accompanying drawings. which show the p ferred embodiment ot' the invention, and in which` Figure l shows the upper end of a pile with the apparatus mounted on the same, shown in section taken along line 1`l of l'g. 2;

Fig. 2 is a horizontal section through the apparatus along line 2`2 of F'Oj ig. 3 is a further horizontal section through the pile and the apparatus along F.

line 3-3 ot' 1g. l;

Fig. 4 is a detail section through a portion of the collar, along line H of Fig.

ig. 5 is a detail perspective of one ofthe collar sections;

ig. 6 is a detail perspective of the lower end ct a fastening bolt; and

Fig. T is a plan "iew of a. collar section of larger size.

is indicated at l. `ldapted to encircle the pi e a convenient distance from its upper end, is an adjustable collar 2 separate sections adapted to be detachably fastened together by shown in Figs. 4f and 5, the collar are like Z bars in cross section with inner wall 4 having pointed projections or picks 5 for being embedded into the timer, a horizontal shoul er or seat 6 for supporting the joint sealing material herein after described, and an outer vertical wall 7 for retaining said sealing material on the shoulder. g end said sections have suitable perforations 9 is .shown at t e collar and with a curved O for resting againstthc wall ar.

Located above the collar i) embracing member a head l) with depending adapted to surround and embrace the upper-end ot the shown, the timer-embracing member is shaped like a elvlindrical cap member for fitting over the top lower end of ot a cvlindrical pile.

l prefer to employ plaster ofParis for -the material and for this purpose mto the collar 2 around the pilc while in a plas ic condition, so as to l all crevices andgfopeningsf1 the space within the cap'member. Any crevices too large for being automatically plugged up by 'the plastic plaster of Paris may be stuffed with paper or cotton waste to support the plaster until it hardens. rlhe plaster of Paris may be poured into the space between the collar 9. and the pile, either before or after the cap member is mounted.

The cap member may be firmly locked to 'the collar preferably by means of a series o bolts 23, evenly distributed around the pile, and having hooks 24 at their lower end for engaging beneath ribs Q5 at the outer' edge The upper ends of 23 extend through enlarged perforations Q in the head 12. and are screwthreaded for receiving hand-wheel nuts 27 which may e turned for tightening an the bolts drawing up on said bolts. 28 is a grasping ring upon the head of the cap member, whereby the same may The operation of the apparatus is as follows. After the plaster of Paris in its liquid state is poured into the collar 2 and between the pile, and the cap member and the latter is secure y locked to the collar as above described, the plaster of Paris is allowed to set and harden so as to make a substantially hermetically sealed joint between the sides of the timber and 13 of the cap member. Thereupon the wood-treating fluid may be introduced through 'the pipe 1 der pressure, and the treatment continued to impregnate the timber as far as may be desired. After the treatment is finished, the space between the cap member and the ile may be drained of wood treating fluid out through the pipe 15. The collar 2 may loosening the bolts 23 d to p away its walls 13 from the plaster seal. The lower ends 14 of the walls 13 are flared outwardly as shown, so as to facilitate this breaking away from the plaster seal.'

It will be obvious that a portion of a pile or timber intermediate the ends may e similarly treated, in embracing memb cylinder open at each end, be closed around the timber by means of a detachable and adjustable collar as above described.
