IMPROVEMENT lN APPARATUS FOR IMPREGNAIING TIMBER WITH ANTISEPTICS.

Specification forming part of Letters Patent No. 177,770, dated May 23, 1876; application filed April 1, 1 876.

To all whom it may concern Be it known that I, WALDEM AR THIL- MANY, of Cleveland, in the county of Guyahoga and State of Ohio, haveinvented certain new and useful Improvements in Apparatus for Impregnating Timber with Antiseptics and I do hereby declare that the following is a full. and complete description'of the same, reference being had to the accompanying drawings, making part of this specification, in

which t Figure is a side view of the apparatus as applied to the timbers. Fig. '2 is a longitu dinal section. Figs. 3 and 4 are transverse views. Figs. 5 and 6 will be referred to.

Like letters refer to like parts in. the several views.

This invention is an apparatus for conducting the process of charging timber with antiseptics for their preservation from decay. The apparatus is constructed and operated substantially as follows:

The apparatus referred to consists of an elastic band or ring, A, of rubber, or other suitable material, rubber being preferred for this purpose. On each end of the band is fitted a metal clamp, B and C, respectively, as will be seen in Figs. 1 and 2. Said clamps may consist of two or more sections or arcs of a circle, the ends of which are. turned outward, forming ears, in which bolts D are inserted, whereby the sections are connected to each other and clamped tightly around the band, as will be seen in the drawings. E is a stop-cock, secured in the band A, and to which is attached a hose, F. The practical application of the above-described apparatus, to the timbers for the purpose specified is as follows:

In practice it is found convenient to treat two pieces of timber or logs at once, and which pieces of timber may be both of a size or of unequalsize or lengths, as shown in the drawings, in which G and H represent two logsor timbers. I. The ends of the timbers are cut straight across, and are then brought close to each other, leaving a space between them,

as will "be seen in Fig. 2 at I. 'Over the proximated ends of the two logs is placed the band A, as shown in said Fig. 2. Should there be a difference in the size of the two logs, as shown in the drawings, the elasticity of the band will allow it to stretch and adapt itself to this difference, also, the clampsmay be pump, hydrostatic pressure, or other suitable means connected to the apparatus by the hose F, is forced through the stop-cock E into the space I between the logs, thence into the pores of the wood, thereby charging the timber with the chemicals, for the purpose specified. In the event extraordinary pressure is expected to be exerted in order to charge the timber, to prevent the band from being forced from the logs, a clamp may be used, having a rib along the inner side, as will be seen at b, in Fig. 6, which'represents a transverse section of a clamp with the rib buried in the band 0. This rib will prevent the band from pulling out from under the clamp. In place of the rib a piece of wire may be placed around the band under the clamp, as'will be seen in Fig. 5. This expedient, however, will not often be resorted to, as the band can be bound sufficiently tight to the logs without.

In making the clamp in several sections it will readilyadapt itself to the ends of logs 2 I 19mm ride of barium and sulphate of copper; but v2. The elastic band A, open at each end to other chemicals may be used with the apparareceive a log, in combination with clamps B tus for the same purpose. and'G, and pipe 'F, in the manner as described,

What I claim as my invention, and desire and for the purpose specified. to secure by Letters Patent, is-- 1. The combination of the elastic ring or WALDEMAR THILMANY. band A, clamps B and 0, consisting of two; or more sections each, stop-cock E, and pipe Witnesses: F, substantially as described,{and for the pur-; H. BUZBHHDGE, pose set forth. E. 'W.=OR0ss.
