EMBOSSING MACHINE.

Application filed February 20, 1923. Serial No. 620,271.

To all whbm it may concern:

Be 1t known that I, EDWIN H. REIBER, a citlzenof the United States, and a resident of West Webster, in the county of Monroe and State of New York, have invented a new and Improved Embossing Machine, of which'the following is a full, clear, and exact description.

'This invention relates to improvements in embossing machines,and has particular referenc'eto a machine for embossing wood slabs or'panels especially usedin building bird houses, such as disclosed in my Patent Number 1,185,345, dated May 30th, 1916.

In the construction of houses such as described in the above patent, it has been cus tomary to employ sassafras and red cedar, both of which woods are of the bark bearing type. It has further been found that the use of these woods is not essential in constructing the houses and may be dispensed with in lieu of some other timber having the appearance of being bark bearing.

,An object of the present invention is to provide an improved machine which may be utilized to char a slab of wood in suchmanner that thesame will be given antique grain and wood bark effects suchas in sassafras wood. 7

Another ob ect is the provlsion' of 1mproved means for positioning a slab of wood with respect to the embossingv roller and feeding-the slab thereto whereby the embossing operation is'facilitated. I

A'further object isto feed a slab of wood into direct contact with a rotatable embossing elementby the cooperation of said element with other means having a relative movement with respect to said element.

A still further object is the provision of a rotatable embossing roller having direct contact with a slab of wood to emboss the same and which is heated by a flame projected into one end thereof.

The above andother objects will appear vmore clearly from the following detail description, when taken in connection with the accompanying drawings, whichillustrate a preferred embodiment of the inventive idea.

In the drawings Figure 1 is a front elevation of the .machine, partly in section, and taken on the line 1 1 of Figure 2;

side elevational view taken of Figure 1;

2 Figure 2-is a on the line 2-2 Figure 8 isa section on the line 33 of Figure 1;

Figure 4 is a section on the line 44 of Figure 1;;and V Figure5 is a fragmentary plan view of oneof the slabs showing the result of the embossing operation.

- Referring more particularly to the companyingdrawings, the numeral 10 indicates the main frame which includes a pair said screw member being engaged in the lower portion of the frame 12 so that upon rotation of the member 15 a vertical movement in either direction may be imparted to said frame 12. Extending laterally or forwardly from' one vertical edgeof the frame 12 is a web 17 having its upper end formed with a horizontally disposed platform. 18 arranged forwardly and to one side of the frame 1 2. A pair of parallel guide strips 19 are mounted uponthe platform 18. These strips are arranged for adjustment toward and away from each other by'the provision of transversely extending slots 20 formed in the platform 18 so that vthe strips may be properly adjusted to re ceive therebetween the slab of wood 21, which is first .mounted upon the platform between said strips preparatory to the embossing operation. In the formation. of these slabs the same are preferably provided with a flat surface and a convex surface, as illustrated in Figure 1, but it will be readily understood that said slabs may haveother configurations without departing from'the spirit or scope of the present invention.

Journaled in the upper portion of the frame 10 and extending transversely thereof is a shaft 22 having a pulley 23 at one end thereof by means of which the shaft may be rotated, the opposite end of the shaft projecting beyond the adjacent side of the frame and having detachably mounted thereon an embossing roller support 2st including a plurality of arms 25, the free ends of which have fdetachably secured thereto the embossing roller 26. This roller is pr.ovided with an open end and, in the present instance, is shown as having an annular concave embossing surface 27, although it is to be expressly understood that this surface may be convex or flat. It will also be obvious that the roller may have a plurality of adjoining concave or convex embossing surfaces in the event that it is desired to emboss a slab of relatively greater width than the one shown in the drawings. Projecting-from one side of the frame 10 and at the upper end thereof is a horizontally disposed supporting arm 28 which supports a hanger 29 adjustable longitudinally of said arm, said hanger in turn supporting a heating element 30, preferably in the form of'atorch which is utilized to project a flame into the open end of the roller 26, whereby to adequately heat the same to accomplish the embossing operation when the slab 21 is brought in contact with the roller 26. The interior surface of the roller 26 maybe provided with a lining 31 of any suitable heat retaining Substance which will aid in'maintaining the temperature of the roller constant.

A second shaft 32 is journaled in the upper end of the auxiliary frame 12 and has one end projecting from the side of the frame rearwardly of the platformlS. A pair of feeding rollers 33 are mounted upon said end of the shaft 32 and adjustable thereon toward and away from each other so as to properly engage slabs of different widths. The feeding rollers are positioned directly below the embossing roller 26 and have theirperipheries arranged in the same plane with the supporting surface of the platform 18 so that as the slab21 is pushed rearwardly from said platform the rollers 33 will engage the under surface thereof and feed the slab between the same and the embossing surface 27 of the roller 26. From the foregoing description, it will be obvious that the vertical adjustment of the frame 12 is provided for. the purpose of accommodating various thicknesses of slabs between the rollers 26 and 33, thus permitting engagement of the surfaces of the slabs to be embossed with the embossing surface 27 regardless of the thickness'of said slabs.

In order to facilitate the feeding of the slabs between the rollers 26 and 33, said rollers are driven in opposite directions by means of spur gears 34 and 35 carried,

respectively, by adjacent ends of the shafts centric with said pivot and at all times in engagement with the gear 35. The gear 36 is arranged adjacent one end of the arm 38 so that when said arm is swung about its pivot 39 the gear 36 may be adjusted toward and away from the gear 3t. The plate 40 is provided with an arcuate slot 41 through which extends a pin 12 carried by the arm 38, a wing nut or other fastening device43 being threaded upon said pin and engageable with said plate to retain the arm 38 in various adjusted positions. reason of this construction, it will be obvious that the arm 38 may be adjusted'to disengage the gear 36 from the gear 34 to stop the rotation of the shaft '32 and, conse .quently, of the feeding rollers 33 and also that when a vertical adjustment of the frame 12 is made with a consequent movement of the gear 35 toward or away from the gear 3 f, an adjustment of the arm .38 may be accomplished to properly intermesh thegears 3a and 36 so that the shaft 32 may be rotated.

' In the operation of the machine, a slab '21 is first placed upon the platform 18 between the guide strips 19 and then forced real'wardly to engage the under surface thereof with the peripheries of the feeding rollers 33 and the upper surface thereof with the embossing surface 27 of the roller 26. The rollers 26 and 33 being driven in opposite directions will cooperate to withdraw the slab from the platform 18 and the heat applied to the embossing surface 27 will be transmitted to the upper or convex surface of the slab 21 and char said surface as the same is passed beneath the roller.

The design of the embossing surface 2 7 may be made to produce antlque gram and bark effects, such as found on Sassafras .wood and after this design has been transferred to the upper surface of the slab the charred wood is brushed off and the raised portions of the surface sanded, leaving the finished product. By charring or burning the surface in the manner herein described ment with said embossing surface, a heating element arranged to project a flame into the open end of said roller to heat the same, and

a heat retaining lining for-the interior of said roller. I v
