I This invention relates to improvements upon" the machine illustrated and appearing in my Patent #1,012,609, of Dec. 26,1911,

for veneer taping machines.

The lobjects'of this invention are 7 First, to provide an ili-iproved arrangement of feed rollers for such a taplng' machine to insure'a perfect joint. H 7 Second, to prov de an lmprovedconstrue' I tion of feed bed that facilitates the matching of veneers.

l Third, to provide improved means of ad justingthe tension on the feed bedpres'ser Objects pertaining to details anddeeono mies of construction and operation will ap-v pear froin'the description to follow.

' Preferred'embodiments of my'invention are illustrated in the accompanying drawings in which: I v j r j v Fig. 1. isa perspective view of a machine embodying the features of my invention.

. "1 is a heavy cast iron base having a lateral supporting arm 2 which carries the bottom portion of feed and guide devices as well as the table A laterally projecting arm 3' is above the said arm-2 and carries the tape feeding mechanism and other cooperat ing parts of the feed tape and veneer. Y

On'the outer end of the side pieces 4', 4 carryin -a top]plate at the level of the table 5,566 fi -a2 and A pair offeed rolls6 6 are carried on the shaft? Y which isjournaled in the side pieces4jf The said shaft extendsba'ck of the'base l where g r arm? are supported are supported each on a journal 14, 14 which A I journals converge downwardly toward each I other and are carried .on the independently yielding block 15,15, the said journals'being seated in suitable journal bearingstherein as clearly appears in Fig. 10; 1

The blocks 15 are in vertical ways 16, 16

which ways are adjustable by means of set hold the said lever and springs in adjusted position. j j

A guide 24 is provided with a vertical central guiding blade 24:1, to deliver the matched veneer to the machine. Auxiliary endless conveyor feed bed means are provided to carry the veneer forward along the said guide. eonsistsflof a main support25 suitably joined to the tabletop. 5. The front roll 26 of the'end-less conveyor i-scarried on shaft 261,

journaledin extensions ofside plates 4. The forward roll 27. is-carried on the shaft 271.

Shaft 2 711- iscarried on 'theadjustabl'e bracket 28 which is. adjustably attached by the set screws 281 inslots 282as-seen in Fig. 6. The

' bracket 28 is provided with belt 288 which extends through a 1ug'251 on the support 25.

The bolt 283is screw threaded on its inner portion and carries compression spring 284 which reacts on adjustable nut 285 and against lug 251 to; force the conveyor roll 27 yieldingly intothe endless conveyor belts 29'. A:

pair of endless feed! bed conveyor belts 29, '29

are "carried on the rolls-26, 27. The-rolls are contlnuous between the'two conveyors and are preferably knurled so that conveyors 29. 29

are operatedexactly equal andlparallel'; This makes it possible to arrange matched veneers on the same andzonmerely pressing the same forward they will advance evenly to .the point where the feed rolls'will engage and advance and-pass the same onto the gluing apparatus.

7 Guide shoe 30,.1adjustably carried on the arm 3,, is disposed in front of the vertical blade 24 1. Presser feed roll- 31 driven from shaft 311 is carried in an adjustable frame 312 which also carries the shoeBO. Presser feed roll 31" is tangent to the feed bed press roll 18 at a point little in advance of the center plane of theiraxes so -that there is a tendency v to slightly deflect the veneer strip 33 upwardly at its discharge end. This insures edgetoedge contact. and compression of the joint.

my former. patent except that they are disposed. at an angle to converge inwardly. They serve to compress the strips of veneer toward each. other as they are engaged by thedrivenifeed roll 6 in thefeed bed. They are'disposed.aconsiderable distance apart as is clearly seen in Figs. 4: and 8 and engage the veneers-each side of thetape.

Pressrolls 32 are like-the press rolls42 of The mechanism for controlling their elevation is very simple and is precisely like that illustrated in my said former patent, and does not need to be further detailed here.

I have shown my invention added as improvements to my said former patent. It is clear that the structures can be considerably modified in detail without departing from my invention.

I'desir'e to-cl ai-m-the invention in itsspeciiic form as illustrated and also broadly as pointed out in the appended claims.

Having thus described my invention what I claim. as new and. desire to secure by Letters Patent is:

1. In a veneer tapingmachine, the combination of a feed bed,adriven feedroll therein, feed bed presser rollsconical in form and dis posed on converging shaft axles, spring pressed blocks therefor'disposedin suitable sockets in the said frame,- an adjusting lever for .thesprings ofsaid blocks extending to the front of the said machine, an upper driven feedrolldisposed in tangent relation to the spring pressed feedbed rolls in advance of the center line of their axes, presser rolls in advance of the said feed rolls, having' screw thread spiral grooves thereon disposed diagonally to converge toward the feed roll' and disposed to engage the veneers each side of the tape, an auxiliary feed bed in advance of the said veneer taping machine, comprising a bed having. a central. dividing guiding rib,-continuous conveyor rollers at front and rear of the means for adjusting the same, and

a pair of continuous'feed;beltsdisposechat opposite sides of the saidcentral dividing rib to operate. 1n HDISQII/ to advance veneers evenly andin matched relation to the said taping machine. 7

2. In a veneer taping machine, the cornbrnation-of a feed bed,.a driven feed rol l therein,

3. In aveneer taping. machine, a main veneer taping. 1neans,.an auxiliary feed: bed in advance of the said veneer main taping machine, comprising a bed having. a central dividing guiding rib, continuous conveyor rollers at front and rear oflthe means for adjusting the same, and a pair 0t continuous feed belts disposed at: opposite sides of the saidcentral dividingrib to-operate in unison side of the tape.

to advance veneers evenly andin matched relation to the said main tapingmachine.

4. In a veneer taping machine,the combination of a feed bed, a driven feed roll therein,

feed bed presser rolls conical in form and disposed on converging shaft axles, spring pressed blocks therefor disposed in suitable sockets in the said frame, an adjusting lever for the springs of said blocks extending to the front of the said machine, and an upper driven feed roll disposed in tangent relation to the spring pressed feed bed rolls in ad vance of the center line of their axes.

5. In a veneer taping machine, the combination of a feed bed, a driven feed roll therein, feed bed presser rolls conical in form and disposed on converging shaft axles, spring pressed blocks therefor'disposed in suitable sockets in the said frame, an upper driven feed roll disposed in tangent relation to the spring pressed feed bed rolls in advance of the center line of their axes, and presser rolls in advance of the said feed' rolls, having screw thread spiral grooves thereon disposed diagonally to converge toward the feed roll and disposed to engage the veneers each In witness whereof I have hereunto set-my hand.
