AEPLIUATIOH IIIIIIIIIIIIII v ALFRED A. ANDERSON, OF JAMESTOWN, NEW YORK.

VENEER-CLAMP.

Specification of Letters Patent.

Patented NOV. 26, 1907.

Application filed July 9.1906- Serial No. 325217- To all whom it may concern:

Be it known that I, ALFRED A. ANDERSON, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented a new and useful Veneering-Olamp, of which the following, takenin connection with the accompanying drawings, is a full, clear, and exact description The invention relates to the art of veneer- 111g boards or moldings and the device here shown is designed more particularly for veneering round or unequal surfaces; and the objects of the improvement are, first, to provide a clamp of flexible, fibrous, non-elastic material, and means to cause it to conform to unequal surfaces, pressing the veneer firmly against the gluecoated surface at all parts; and second, to arrange said clamp in a cooperating series so that a number of pieces of molding may be veneered simultaneously therein.

In the drawings, Figure 1 is a plan view of a loaded veneering clamp, in series. Fig. 2 is a sectional view at line X X in Fig. 1. Fig. 3 is an end view of the upper half of the clamp with strips of semi-circular molding attachedready for coating with glue. Fig. 4 is a plan view of a clamp having edgewise bowed strips. Fig. 5 is a partial sectional view of the clamp, showing the upper half raised and a veneer strip in place to receive the wood to be veneered. Flg. 6 is a partial cross-sectional view showing inserts to reduce the size of the clamping space. Fig. 7 is a partial cross-sectional view showing a screw pressed curve-topped strip to press the flexible clamping material veneer into an ogee or return curve molding. Fig. 8 is a side elevation of a clamp having another form of bowed strips from those shown in Fig. 1. -Fig. 9 is a partial cross-sectional view showing a modification of the adjusting means for the curve-topped strip, shown in Fig. 7 to press the veneer into an ogee moldmg.

, Similar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the heavy upper cross bars or clamping pieces, which are made of sufficient size to hold the parts stifl'ly in place. Similar cross pieces 11 are provided at the lower side, and bolts 12 are provided in the ends of the lower cross pieces 11 cross pieces 10 with suitable thumb nuts 13 to compress the parts. A series of lengthwise bars 14 are attached to pieces 10 by bolts 16 in slots 15. Lengthwise bars 14- have the points 17 extending therefrom 011 their lower side for attaching the wooden forms 18, to be veneered. that the wooden forms 18 may be "attached to lengthwise bars 14 by the points 17, as shown in Fig. 3, and that when so attached the series of strips of molding 18 are in convenient form for coating with glue.

The lower half of the clamp has the length wise bars 19 attached to cross pieces 11 by bolts 20 in slots 21. The central bar 19 of the series is bolted firmly in place without the slots 21, and the under sides of the other bars 19 each side of said central bar are given a slightly beveled opening toward said central bar so that when pressure is applied, the lengthwise bars 19 on each side of said central bar will be drawn to\\"ard said central bar, the slots 21 for bolts 20 and 15 for bolts 16 allowing of such movement toward the central bar, thereby adjusting automatically so that all arts of the rounded surfaces receive equa pressure.

The upper edges of bars 19 are connected by a sheet of heavy cloth 22, preferably heavy canvas, which material is found after being placed under heavy pressure to have sufficient strength and to be practically nonelastic, not stretching to any extent under pressure, but holding the veneer firmly to place on the glued surfaces. The canvas 22 is attached to the upper edges of bars 19 and allowed to loop downward slightly between the bars 19 according to the rounded surface to be glued. VVhon it is desired to diminish the space between the bars 19 for small molding, strips 23 are inserted at each side of the space between the bars 19 beneath the canvas 22. Inserts 23 may be of dill'erent thicknesses according to the amount which it is desired to diminish the space between the bars 19; they should be of equal thickness in order to equalize the space.

Lengthwise bars 1 1, and 19 with the sheet of canvas may be made in the curved or bowed forms, as shown in Figs. 4, and 8, so that rounded molding in the sidewise curved or bowed form may be veneered.

In case of an upward or return curve 25 in the molding an additional lengthwise bar and project through the ends of the upper 26 with a round upper surface is provided It is apparent.

beneath the canvas 22 with adjusting screws 1 27 mounted in lower pieces 11, said screws having squared lower ends so that they can be adjusted by means of a suitable key.

In use, the stripsof wood to be veneered are fastened on the lengthwise bars 14, as

shown'in Figs. 3 and 5. The strips of ve- I neer 28 are placed in position on the bars 19 beneath the molding 18, as shown in Fig. 5.

'vas 22 will press the veneer on to the outer curves, and that the pressure of the curvetopped strip 26 may be adjusted to the pressure of the canvas so as to press the veneer into the central upward curve with an equalized pressure. Coil springs could be used between strip 26 and pieces 11 in place of screws 27, and serve agood purpose as shown in Fig. 9. Such springs are found, however, to soon lose their elasticity, and hence the screws 27 are preferred.

It is obvious that cross pieces 10 and 11 on the upper and under sides form supports and that the clamp can be used either side up, though it is usually preferable to use the clamp as shown in the drawing. It is evident also that different forms might be given to bar 26 in order to fit different styles of molding without de arting from the invention. It is found, owever, that a simple oval strip attains the purpose and gives suflicient pressure to cause the veneer to adhere. The screw 27 may be mounted in cross bar 11 at different angles in order to press the strip 26 into the different styles of molding, though this is rarely necessary.
