To all whom it may concern:

Be it known that I, REUBEN C. DAYTON, residing at Rhinelander, in the county of Oneida and State of lVisconsin, have invented certain new and useful Improve ments in Gage-Tables, of which the following is a specification.

This invention is a gage table for use in connection with veneer clipping or cutting machines or the like, and the invention primarily has for its object to provide a gage table whereby the clipper operator may cut the veneers to such dimensions as desired with the minimum effort and maximum accuracy.

As now practiced in the art it is customary to use a wooden table having a slatted top onto which the veneer projects from the clipping machine. A yard stick or other measuring instrument is used to measure the width of the veneer that projects beyond the cutter onto the table, so that a strip of the desired width may be clipped off. In the trade, veneers are bought and sold according to their dry dimensions, that is, their dimensions after they have been dried and seasoned. The veneers when clipped have been directly out from hot boiled or steamed logs and are saturated with water. A large shrinkage takes place in the process of drying and in order that the veneers when out shall come up to the desired dry dimensions, the clipper operator must make an allowance for the shrinkage. The percentage of shrinkage varies with the difierent woods and the locality and climate in which the timber grew, so that when an order is placed with the clipper operator to be cut out, the shrinkage has to be figured on each differentwidth and enough added so that the pieces when dried shall be of the required width. This process entails a large amount of clerical work in figuring shrinkages with constant liability of errors.

My invention therefore has for its object to provide a gage table wherein means are provided to set the veneer strip with respect to the veneer clipper, so that when out and dried it will be of the required dimensions; and to so provide a gage table of the character stated that the changing, from one width to another, of the mechanism may be made by a nonskilled operator with absolute accuracy.

More specifically the invention provides a pair of butting blocks slidable in unison over the table and against which the veneer strip engages, and the provision of a gage whereon the shrinkage 1s allowed so that the scale Wlll read in feet, lnches and fractions of inches directly but with the required correction for shrinkage. Means are also provided so that the butting blocks may be operated from one side and moved to any desired position, while another means is provided for limiting the movement of the blocks in a given direction when it is desired to change their position for any purpose so that when the blocks are again moved back to their original position it will be unnecessary for the operator to again consult the scale.

Sometimes it is necessary to trim stock after drying and allowance must be made therefor.

My invention also has for its object to provide means whereby the gage may be so adjusted that the desired allowance for trimming may be made in clipping the stock.

In its more subordinate nature, the invention also embodies those novel details of construction, combination and arrangement of parts, all of which will be first described and then be specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1, is a perspective view illustrating the application of my invention. Fig. 2, is a similar view of my invention, a part of the table structure being removed. Fig. 8, is an enlarged detail perspective view of one of the butting blocks, showing its connection withthe gage bar. Fig. 4c, is a cross section on the line 4t-et of Fig. 3. Fig. 5, is an enlarged detail plan view of one end of the gage carrying bar showing the provisions for adjusting the gage or scale to allow for trimming. Fig. 6, is a detail central vertical longitudinal section of a part of the invention. Fig. 7 is a detail view of a gage bar. Fig. 8, is a top plan View of the device.

Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the figures, l designates a table having slats 2, certain of which 33 are made of metal and are supported on standards 4 and brackets 5. Thebrackets 5 are fastened at 6 to the front beam 7 of the table 1, while the standards 4 rest on the floor. Each standard t and bracket 5 carries a sprocket wheel 8 and 9,

respectively, while an endless chain 10 takes around each pair of sprocket wheels 8 and 9. Each chain 10 engages a drive sprocket 1111 on a shaft 12 that is journaled in bearings 13. A fixed ratchet wheel 14 is secured to the table 1 and has an aperture to form one of the bearings 13 for the shaft 12. A hand wheel 15 is secured to the shaft and has a handle 16 pressed by a spring 17 into normal engagement with the ratchet face 18 of the ratchet wheel 14 to hold the shaft in its various positions.

A carriage or butting block 19 rides on each bar 3 and is secured at 20 to the respective chain 10, so that both carriages 19 will be moved in unison by such chains as the shaft 12 is turned. Each carriage 19 has a knee or block 21 at its front endto abut the veneer strip 30 as it is projected onto the table 1 from the clipper 31.

One (or both) of the bars 3 is provided with a dove-tail groove 22 in its upper face in which a gage bar 23 is removably held by a set screw 24 that passes through a slot 25 in the gage 23 and enters the bar 3. The gage bar 23, shown in detail in Fig. 7, forms one of the primary features of my invention in that while the scale is graduated in feet, inches and fractions of inches the shrinkage allowance has been added thereto. For example, if the operator is cutting wood that shrinks 8 1per cent. of its width in drying he uses a gage 23 calibratedon that percentage, so that if a cutting order calls for a width of veneer, say, 23 inches wide (dry) the operator set-s his block at the mark indicating 23 inches and clipsthe veneer; in reality the strip clipped is 25 inches wide when clipped, but as it shrinks 8 per cent. in drying it comes out the required width of 23 inches when ready for delivery. The gage bars 23 are made removable so that a gage bar for any kind or texture of wood may be usedsince different woods have different co .efficients of shrinkage, and therefore -a gage having its scale graduated to allow for shrinkage intended for use in connection with oak wood, would be unsuitable for use in connectlon with maple and a separate scale must be used therefor.

Sometimes stock must be trimmed after drying and in order to make allowance therefor I provide the slot 25, which in practice.

is about 1% inches longand the gage bar 23 may be provided with a supplemental scale 26 graduated-in ,pure inches and fractions of inches to cooperate with an indicating mark 1 27 on the bar 3 for convenience in setting the scale. Thus if the operator desires to allow of an inch in width in trimming he loosens the set screw 24 and moves the gage. bar 23 until the mark corresponding to inch on the supplemental scale 26 registers.

with the indicatormark 27 and tightens the screw 24 so that each piece of stock when cut will not only carry the shrinkage allow-. ance but also the g of an inch trimming a l-. lowance.

Gages figured on different percentages of shrinkages may be made so as to apply to all the different kinds and texture of wood and by constructing the bar 3 and gage 23 as described, the gages 23 may be interchanged with great rapidity and as frequently as desired. On the side of the part 3 is a series of holes 28 drilled closely together to receive pins or pegs 29, so that if the operator is clipping for two widths, but has occasion to shift his blocks for other widths as the condition and defects in the stock may compel, and if he is cutting, say, 6 inches and 15 inches stock, he puts a peg 29 into the hole in front of the block at 6 inches, slides the block back to 15 inches and places a peg behind it so that he can shift the block forward to 6 inches or back to 15 inches without even looking at the table.

In the practical application of my invention the table 1 is moved up into engagement with the veneer clipper 31, (which clipper may be of any approved type, as the same, per sc, forms no partof my present invention) to receive the veneer 30 as it passes under the clipper knife onto the table 1 and the carriage blocks 19 being set to the desired position, the stock will cease moving as it engages such blocks and the operator may then set the clipper into motion to clip the section of the veneer strip to the size desired, after which said strip may be re moved and a second section clipped in a similar manner.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.
