HAND SEINGLEh-STAINING MACHINE.

Application filed literati 17, 1824. Serial No. 699,894.

This invention relates to a machine for staining wood and the like and it is particularly applicable for use in staining shingles. The primary object of the invention is to provide an inexpensive, durable and practical machine for staining shingles, there being means provided for supporting the shingles in a vat of stain and in addition there is an agitator for maintaining the pigment in suspension in the liquid, that is the agitator prevents the pigment from settling to the bottom of the vat or tank. As a refinement of the invention, means is provided for varying the position of the shingle-support ing grid to compensate for variations in the level of the stain in the tank or vat.

The novel construction of the invention will be described in detail hereinafter, reference being had to the accompanying drawings, in which- Fig. 1 is a vertical longitudinal sectional view through a shingle staining machine constructed in accordance with my invention.

Fig. 2 is a cross sectional view through 35 the machine, and

Fig. 3 is a fragmentary perspective View of the shingle-supporting grid.

Referring now to the drawings by numerals of reference 1 designates a tank or vat having at its top angle brackets 2 and 3 in which are mounted vertical shafts l and 5 at the top ends of which are handles or cranks 6 and 7. The shafts 4i and 5 depend into the tank and the lower ends thereof are threaded as at 8 and 9. The threaded ends 8 and 9 extend through the transverse strips 10 and 11 of a shingle supporting grid 12 having side bars 13 and 14L and cross bars 15 upon which the shingles are supported. The threaded ends of the shafts also extend into and engage the threaded openings 16 and 17 of the end bars 18 and 19 so that when the operator turns the cranks 6 and 7, the threaded engagements of the shafts land 5 with the end bars 18 and 19 will cause the grid to be raised or lowered to compensate for variations of the level of the liquid 20. The liquid of course is the stain and the pigment is held in suspension rather than in solution, so it is desirable that some means be provided for agitating the liquid to maintain the pigment in suspension and to prevent its settling to the bottom of the tank or vat 1.

The agitator is shown as consisting of a shaft 21 journaled in bearings 22 and 23, the latter being in the form of a stufling box so that one end of the shaft may extend through the tank or vat to carry a pulley 9A driven by the belt 25 which passes around the pulley .26 on shaft 27. The shaft 27 is mounted in a bearing 28 on the side of the tank or vat. The shaft 27 carries a pulley 29 driven from the pulley 30 on the shaft of the motor 31 by a belt 32. The shaft 21 carries a plurality of spiders designated 33,

34 and 35 respectively.

The ends of the spiders support spiral blades 36, 37 and 38 which rotate with the 79 shaft since the spiders are fixed on the shaft 21, consequently when the motor 31 is functioning, the power is communicated through the transmission consisting of the belts and pulleys above described to the shaft 21 causing the agitator to operate in the tank below the grid and set up a sufliciently violent agitation to maintain the pigment in suspension and therefore allow the shingles to be stained evenly. At the bottom of the 90 tank is a flow-oft pipe connection 39 for drawing off the stain at an appropriate time.

It will be apparent that the shingles may be introduced into the tank so that they will be supported upon the grid and that the grid can be adjusted vertically to compensate for variations in the level of the liquid stain and that they will be stained enly because the agitator will maintain the stain at a uniform consistency and equally distribute the pigment throughout the solution.

Such a device as is illustrated in the accompanying drawings can be manufactured at a relatively small cost and yet it will efliciently perform the function for which it is intended.

hat I claim and desire to secure by LettersPatent is:

1. A shingle staining machine comprising a liquid containing tank. a shingle supporting grid in the tank, said grid serving as a gauge to determine the extent of said shingles into the liquid, means for vertically adjusting the grid within the tank to compensate for variation of liquid in the tank so that as the liquid in the tank recedes the grid may be lowered accordingly, said means comprising threaded shafts held against longitudinal movement but having threaded engagement with the grid to hold said grid in any adjust-ed position.

2. A shingle staining machine comprising a liquid containing tank, a shingle support ing grid in the tank, means for vertically adjusting the grid within the tank to compensate for variation of liquid in the tank so that as the liquid in the tank recedes the grid may be lowered accordingly, said means comprising threaded shafts held against longitudinal movement but having threaded engagement with the grid and a liquid agitator in the bottom of the tank below said grid. 3. A shingle staining machine comprising a liquid containing tank, a shingle supporting grid in the tank, means for vertically adjusting the grid within the tank to compen- 2 sate for variation of the level of the liquid in the tank so that as the liquid in the tank recedes the grid may be lowered accordingly, and a liquid agitator in the bottom of the tank below said grid. said grid being interposed between said agitator and said shingles.

In testimony whereof I ai'iix my signature.
