CLAUDE ROY, OF PARIS, FRANCE.
Specification of Letters Patent.
Patented Oct. 19, 1920.
Application filed May 28, 1919. Serial No. 300,302.
To all whom it may concern Be it known that I, CLAUDE 1101', a citizen of the French Republic, and a resident of Paris, in the Republic of France, have invented Improvements Relating to Rendering Wood Impermeable and Recovering Liquids Contained Therein, which invention is fully set forth in the following specification.
My invention relates to apparatus for rendering impermeable newly felled timber in logs and removing from such timber the therein contained sap, in order to avoid subsequent Warping of the wood cut from the timber and to permit its being glued. My invention therefore has for its object to enable the timber to be utilized immediately for general industrial purposes and, particularly, for the manufacture of propellers.
The apparatus in accordance with my invention permits, moreover, the recovery of the liquid products contained in the timber with a view to the ultimate utilization thereof.
By means of my apparatus a liquid S0111.
tion is injected into the timber which penetrates into all the channels thereof previouslywashed by an injection of water.
To obtain good results, a liquid solution of casein is injected which solution is prepared by diluting the casein in water to which is added a certain amount of ammonia and quick lime in suitable proportion.., in order that the injection can be effected.
When the injection of casein is finished, the timber is divided into planks and subjected to drying in a hot chamber, at high temperature, which completes the impermeabilizing by precipitating the solution of casein.
"For casein can be substituted any substance having properties and being' of a apparatus at one end of the log and the other apparatus at the other end of the log.
The timber treated as indicated above is perfectly impermeable and becomes refractory to the action of heat, moisture and llght; it does not warp and it glues easily, especially if for this operation glues having a casein base are employed.
Moreover, the casein or the solutions can be mixed with a coloring substance of any kind for the urpose of imparting any desired tints. y injecting the liquid in an irregular manner and intermittently, veins more or less dark are formed.
One form of apparatus for carrying out the objects of my invention is shqwn, by way of example, in the annexed drawing in which Figure 1 is an end elevation of part of the apparatus.
Fig. 2 is a side elevation partly in section of the same part.
Fig. 3 is a partial longitudinal section thereof.
Fig. 4- is an elevation showing the arrangement for clamping logs separately.
Fig. 5 is a plan, and
' Fig. 6 a sectional end elevation thereof.
Fig. 7 shows the clamping arrangement applied to a log.
Fig. 8 is ahalf end elevation of an apparatus showing a modification of the tight i joint and the clamping means suitable for logs of medium diameter. Fig. 9 is a longitudinal section thereof. Fig. 10 shows in side elevation, on a smaller scale, an arrangement for securing logsof large diameter on the apparatus.
Fig. 11 shows another modification of the 7 device for securing a log and the joint-forming head, for logs of great length and small diameter.
As shown in Figs. 1 to 7 the apparatus comprisesa support a, on which is fixed a base 1b carrying a spindle c, on which by a lug d is pivoted a cylinder 6, ending in a flange 6 having ears 6 The flange e is recessed toflprovide a circular chamber in which fits the end of a cylindrical body 7, having chocks f in which are pivoted threaded bolts g, adapted to engage in the earsc on the flange e and carrying nuts.
These bolts 9, the nuts of which bear against the cars 6 hold the cylinder 6 and 'bine the action of the two in applying one the body f rigidly to ether. A packing ring 6 insures the liqui tightness of the connections.
The cylindrical body 7 has a recessed flange f for the reception of a ring h, of which the internal diameter varies according to the thickness of the log, spikes h being also provided for entering the end of the log 2'.
A packing ring j, interposed between the ring h and the end of the log i insures the tightness of the joint between these two.
The log is clamped by means of a contrivance is pivotally connected and interpivoted by small links composed of links 1: each of these links it has two cheek plates 70 presenting a series of teeth intended to enter the log for the purpose of preventing it from turning.
The clamp is tightened around the log by coupling screws m, the stems m m of which are pivoted in lugs n carried by the end links is. Threaded bolts 0 provided with nuts (Fig. 2) connect the clamping contrivancewith the flange f of the cylindrical body The end of the cylinder 6 carries two bosses p, 1, to which are secured two inlet pipes s, t, one of which 8 is connected directly to a pump (not shown) when a single element is secured on the support a, and of which the other t is connected to a manifold pipe u mounted on the support a when the apparatus comprises several elements placed in series.
In the arrangement shown in Figs. 8 and 9 applicable particularly to logs of, medium diameter, the internal recess of the flange f of the cylindrical body 7 serves to receive a head or ring it for forminga tight joint between the log and the apparatus.
For this purpose, the head 71 has a circular cutting edge 72 which enters the lo" '5 and it provides a seating it also circular, which is provided for receiving a washer h of rubber or other suitable material, in close contact with the end of the log 2'.
The annular portion of the log 1' comprised between the external periphery of the log and the internal periphery of the joint or washer 71 constitutes the necessary jacket for resisting and compensating the pressures set up by the liquids or compressed air, cold or hot. when injected into the log for the purpose of driving out the excess of liquid or of drying the log or, finally, of introducing under pressure a suitable'gas for decomposing the organic substances. This jacket prevents, moreover, the expulsion or the leakage of the liquids or of the air through the external periphery of the log, this latter being in the open air.
The arrangement for clamping the 'log on the apparatus according to Figs. 8 and 9 omprises an annular disk 1, in which slide stems 2 carrying gripping shoes 3 mounted on the ends of clamping screws 4 passing through a flange of the disk 1, these screws serving to press the shoes 3 against the log causing the grippers thereof to enter the log.
The annular disk 1 and the log which it supports are connected to the cylindrical body f by threaded bolts 5, the nuts 6 of which bear against the flange 7 of the cylindrical body 7.
Logs of large diameter are secured on the apparatus by the arrangement shown in Fig. 10, which comprises the threaded bolts 7 passing through the flange f and having hooks 8 in which are engaged the ends of screw-threaded rods 9, engaged, at the other end, in tightening screws 10.
The rods 9 are extended by other rods 11, likewise screw-threaded, which at one end are engaged in the tightening screws 1.0 while their opposite ends carry claws 12 provided with spikes.
These claws are screwed on the rods 11 until they come into contact with the end of the log 2' and the whole is secured by turning the tightening screws 10 in a manner to exert a pull on the rods 9 and 11 and cause the spikes of the claws 12 to enter the log.
lVhere logs of great length and small diameter are concerned, telegraph poles for example, the head h is extended to form a sleeve h (Fig. 11) in which the end of the log 6 is engaged and the protective acket in this case is obtained by the rubber packing 72 located inthe interior of the sleeve 79,
For such logs, the securing arrangement comprises, as in the preceding case, threaded bolts 7 which pass through the flange 7' of the cylindrical body 7 and are formed with hooks 8.
Cables or rods 13 are attached to the hooks 8 and also to hooks 14 carried by a collar 15, secured on the log t" if desired, at 5 or 6 meters from the apparatus, by clamping screws 16. I
The collar 15, on the other side opposite to the hooks 14, carries hooks 17 in which are hooked screw-threaded rods 18 engaged in tightening screws 19 and extended by rods 20, also screw-threaded and carrying claws 21 provided with spikes which enter the end of the log 2', when the tightening screws 19 are turned to fasten the log.
It will be understood from the foregoing, that the various members of the apparatus and also the log which they hold, are interconnected in a joint forming manner. It is therefore sufiicient for extracting the sap to supply, by means of a pump, water at a suitable temperature to the pipe 8 or the manifold pipe M.
This water, passing through the cylinder e penetrates into the log, from which it drives the sap and liquid products which the log contains; these products are collected in a vat for subsequent utilization.
WVhen the water begins to issue pure, the operation is finished and the log is ready to receive the injection to render it impermeable.
This second injection is effected in the same manner and with the same apparatus by which the removal of the sap has been effected, suitable substances or products bein employed for that purpose.
IVhen the injection is finished, the log is cut into planks, which are made further impermeable by being dried in a hot chamber.
The, apparatus above described enables the injection first into the heart of the log, with the subsequent diffusion of the liquid, gas or hot air by the medullary and concentric channels into all portions of the log, as distinguished from arrangements heretofore employed, such as autoclaves, cast or other iron jackets, etc., by means of which only the alburnum crown can be treated by removal of sap, injection and drying, such being only an insignificant portion of the log.
Moreover, with my apparatus, the treatment can be effected as desired either at the foot or head of the tree, and my apparatus can be employed for the injection of all kinds of liquids for preserving, coloring, fireproofing, etc., wood.
What I claim is:
1. In an apparatus for making logs impermeable, the combination with a support and a cylinder adapted to be secured to the end of the log, of a clamping member composed of serrated links pivoted together and adapted to grip the log to be treated, and tightening screws for drawing the links firmly around the log.
