To all whom it may concern:

Be .1t known that we, MARTIN NYsTnoM- vand Lotus TAXoN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Veneer-Taping which the following is a specification.

Our invention relates to 4taping machines for securing the edges of veneers together and at the same time crowding the tw pieces tightly together, and the objects of our invention are, first, to secure a strip of paper or cloth over the meeting edges of the pieces of veneer; second, to provide means for quickl drying the moistened tape thus applied; t iird, to positively crowd the edges of the veneer together; fourth to make a simple, cheap and durable machine and other feature to become apparent'from the description to follow.

In machines of this class an important feature is to crowd the edges of the two pieces of veneer tightly together at the time that the securing tape is being fastened vto the same and this is accomplished in our machine by positively moving that portion ofthe clamping wheels, which is in contact with the pieces of veneer, toward each other, which obviously moves the pieces of veneer tightly together, and the edges of the veneer are prevented from lapping over4 one another by the pressure of the upper and lower clamping wheels. The movement of a portion of the clamping 'wheels toward each other is permitted by having the rims of the wheels made in sections, sufficient spring for such movement being `afforded in the spokes.

To describe our invention so that others versed in the art to which it pertains may make and use the same we have illustrated ity on the accompanying three sheets ofdrawings forming a which y l `igure 1, is a. plan view of a machine embody-ing our invention partly broken away for the purpose of illustration; Fig. 2,`is a cross section on line 2-2 of Fig. 1.; Fig. 8,

1s a cross section on line 3-3 of Fig. 1; A

Fig. l is a detail sectional View showing a `f raising and lowering device for the upper pressure wheels; Fig. 5, is a plan view of the lower pressure wheels enlarged; Fig. 6,- 1s a side elevation of the upper and lower pressure wheels enlarged; and

Fig. 7, is a section'on line 7 -'`7 `of Fig. 6.

Machine, of-

part of this specification in -sion of the springs Similar reference characters refer to similar parts throughout the several views.

The machine consists of a suitable frame 10 which maybe made of wood and is provided with a table 11, and the pressure wheels etc., which are mounted on said frame. The mechanism above the table 11 comprises the upper pressure wheels 12,

l

13 and 14, the water receptacle 15 and the tape reel 16, while the mechanism below the'table .11 comprises the pressure wheels, 17, 18 and 19. p The'wheels 17 and 18 are rigidly mounted on shaft 20, mounted in frame 10 Vand driven bymeans ofthe connecting gears 21 `from shaft 22 on which is provided a pulley 23 connected by belt 24 to pulley 25 on shaft 26 ,on which is mounted a tight pulley 27 and aloose pulley 28. These pulleys 27 and 28 are connectedby the-usual shifting belt to a source of power not shown.

Theshaft 20 is slowly rotated clockwise as viewed in Figs. 2, 3 and 6, which of course rotates the wheels 17 and 18 in the same direction. The

wheels

12 and 14 above the table 11 are mounted on shaft 29 loosely journaled in the bearings 30 on the free end of the hingedv frame 31 pivoted at 32 to frame 10, and are arranged to rest on the wheels 17 and 1S, so that when the wheels 17 and y18 are rotated the

wheels

12 and 14 will' be rotated through the frictional contact therewith. It is clear that if a piece of veneer or other material is placed between the lower wheels 17 and 18 and the

upper wheels

12 and 14 and the wheels are rotated as described the veneer will be moved along between the upper and lower wheels. To properly feed t-heveneer through between theI wheels it is necessary to have considerable pressure exerted against the veneer and this is done by having the upper wheels spring pressed against the lower wheels by the coiled ex'iand'ing springs 33 interposed between the ree ends of frame 31 and the brackets ,34 secured to frame l0. The tenl 33 can be adjusted by the hand screw 3 It is necessary to lift the

wheels

12 and 14 up away from wheels17 and 18 to stop the veneer from feeding through the niachine and this is accomplished by .providing an upward extending ear 36 on each'free end of frame 31 shaped pivoted at the end corresponding to the bottom ofthe Uand having the wheels' (sa-id frame 31 being U A30 tions of, the rims of wheels 17 and 18, are

The partsare so arranged that the secis preferably wound on a roll 47 supported on a reel 16 secured to a standard 48 mount- 95 ed onthe bracket 34. The standard 48 also supports the water receptacle 15 which is rovided with the water carrying rolls 49 and idlers 5() and 51. The tape 46 passes from the roll 47 over the top roll 49, thence 100 around idler 50, thence again over the uppermost roll 49 thence over idler 51 thence over the curved protecting shield 52 and finally under wheel 13 where it is tightly pressed against the veneer below `the same. 105 The tape 46 on roll 47 has one side prepared with gum or glue and in passing over roll 49, the Gum or glue is moistened so that the strip when pressed against the veneer below wheel 13l will tightly adhere to the 11o same. To assist in the adhesion and drying of the gum or lue on the tape 46, the wheel 13 is constant y heated by any means as agas burner .53 within the `same. The shield 52 is made of non-heat-conducting 115 material so as to rotect the tape 46 from the heat thrown o by the wheel 13.

Of' course the ta e 46 is secured centrally over the meeting ine of the two pieces -of veneer and laps as much over the one piece 12o of veneer as over the other piece of veneer.

To guide the two pieces of veneer into the machine so that --their abutting edges will always register centrally under the wheel 13 andthe tape 46, a long thin upwardly ex 125 tending blade 54 is secured on the table 11, having its one end closeto wheel 13 and its other end extending at lright angles to the verticalplane in which the shafts 20 and Z9 j lie. The gas for the burner 53 is supplnzd me moved toward each other while the twol pieces of veneer are tightly clamped between these wheels 17 and 18 and the

wheels

12 and 14, and thus press the edges of the l-two pieces ofveneer tightly together. The

upper wheels

12 and 14 are constructed with sectional rims similar to the wheels 17 Vand 18 and of course the sections which are tightly pressed against the pieces of veneer when the same is moved by the idlers 41 will move with the pieces of veneer by reason of the frictional contact therewith.

It is understood that the spring in the spokes tends to hold the dierent sections '45 of`the rims of the wheels in their normal position, and as soon as each successive sec. tion passes' the idler 41, so that its cam track 40 is out of engagement with the idler it is returned to its normal position. I`Tlie idlers 41 areplaced in a vertical plane slightly beyond-.th'e plane in which the point of contact between lwheels 17 and 18 and

wheels

12 and 14 lies, so that there will be no tendency 4to move the pieces of veneer apart again 55 when the sections ofthe rims of the wheels are returned to' their normal positions by the spring in the spokes. Obviously the4 particular*construction of the rims of the wheels couldbemodified without departing from the spirit of the invention.

When the two abutting edges of tw v pieces of veneer are forced together there visa tendency for the edges of the veneer to overlap or buckle and to prevent such action Weprovide the lower pressure wheel 19 beends are gripped between thel upperand` lowerwheels and the vtape 4 6 is ted in ungrallylaterally -movable contact members,

der wheel 13... and' then the rotation of.

wheels 17 and 18 on shaft 20 continuato4 feed the pieces of-veneer and the Vtape along through the machine; as the. successive sections ofthe rims of wheels 17 and 18 contact with the Aunder side of thepieces of veneeer they are moved toward ea'ch other -by the action of the idlers 41 andtightly press the edges of the two pieceslo veneer Atogether the ta'pefl is being p` reSs'ed againSt the'upper surface of the two pieces of veneer. Thusthe-two pieces of veneer leave the machine securely held together by the tape. It will be noted that while passing through the machine, the edges of the pieces of veneer have constantly been in a flat position.

Having thus tullydescribed our invention what we claim as new and desire to secure by Letters Patent of the UnitedStates is:
