The machine is shown equipped with five separate vcneer-rta'eiving magazines or compartmcnts. and is adapted to brand simultaneously five long narrow strips of veneer. hut it will he readily understood that the table mav he constructed to acconunodate veneer of any size. The magazines or (ompartments are formed by longitudinal walls or partitions. aml are provided \vith'front walls 1. which terminate short of the upper edges of the side walls or partitions.

The table is mounted upon a cross head 5, provided with an inclined upper face to support the table at an inclination and havin vertical end flanges extending longitudinally of the'cross head and arranged in vertical guide ways. consisting of 'slots 7. formed in the sides of theframe of the 111achine at the front thereof. as clearly illustrated in Figs. 1. 2 and 5 of the drawings.

The cross head is also equipped at its ends with horizontal pivots or trunnions S. and it is connected with crank wheels 51 11v adjustahle connecting rods 10. The crank wheels. which are mounted on a front transverse shaft 11. are located at opposite sides of the machine. and the adjustahlc connecting rods are provided with means for var ing their length to adiust the tahlc to position the same properl with relation to the feeding mechanism. hereinafter descrihed.

The crank disks or wheels are provided opposite the wrist pins 1'. with heavy or weighted portions 13 for countcrdlalancing the crank wheels. The counter-halancing weights are formed hv increasing the thickness of the heavier hall' of the wheels. which are equipped with curved guards 1-1. secured at their terminals to the weighted portions of the crank wheels in recesses thereof and eonstituting a portion of the periphery of the erank wheels to prevent the shoulders and whieh roeks or partially rotates. is journaled in suitahle hearings l! and is eonneeted at its ends with tixed vaeuum tuhes or iipes '20. extending upwardly from the ends of the hollow shaft and then inwardly toward the median line of the maehine to a main air trunk 21. The main air trunk '21.

whieh is lo -ated ahove the median line of the maehine. may he arranged at any other eonvenient point and is eonneeted with a rotary exhaust fan (not shown). whieh exhausts the air in the main air trunk and ereates a suetion in the vaeuum or suetion tithes. The shaft 15. whieh is provided adiaeent to the inner sides of the hearings 1% with shoulders this extended outwardlv heyoud the hearings into sleeves :23. having inner'attat-hing portions 24. and provided at their outer ends with annular flanges 23. The lower ends of the pipes '20 are provided with annular tlanges 2t). whieh are seeured to the tlanges '35 hv mans of serews IT. or other suitahle fastening deviees. suitahle paekings :2 of rnhher. or other material heing interposed hetween the flanges 25 and 2h. The

serews 27 also pieree metallie eollars '2 whieh are litted against the outer fares of the flanges 21' to reinforee and elamp the same. By this eonstruetion air tight joints .hetween the hollow shaft and the vaeuum -tithes or pipes .20 are provided.

The hollow shaft 15 is provided at the hottom with pt'ojeetiug ribs or hosses 3t).

and the tuhes 1t). whieh depend from the hollow shaft. are provided at their upper ends with tlanges 31. seeured to the rihs or hosses hy setews IL. or other suitahle fastening deviees. The depending tuhes it; are provided with redueed lower portions 323 to reeeive the lower teleseopie tithes 1T. whieh are provided at their upper ends with annular llanges or enlargements 34. arranged to engage interior shoulders 35. formed hy interiorly redueing the lower portions of the depending tuhes. The shoulders serve as stops for limiting the downward movement of the teleseopie tuhes. and the tuhes 1 and 17 form extensihle suetion ale viees. and are adapted to aeeommodate themselves to the rta'iproeation of the table with varying quantities of veneer in the. magazines thereof. Eaeh foot 18 is in the form of a eap having a redueed upwardly extending threaded portion or neek 36 to serew on the lower end of the t'eleseopie, tuhes. wherehy the foot is attaehed to the same. The hottom of the foot is flat and is provided with a plurality of apertures 37. through whieh the air is drawn hy the exhaust fan. The suetion ereated hy the exhaust fan enahles eaeh teleseopie tuhe to seeurely grip and hold a sheet of veneer. 'hen the tahle is moved upwardly. the veneer is earried into engagement with the teleseopie lnemhers of the suetion deviees. and the top sheets of veneer are retained by the same' when the tahle movesdownwardly away from the suetion deviees.

The oseillatory pneumatie feeding deviee. whieh engages the sheets of veneer at a point intermediate of the ends thereof. is swung inwardly or r-arwardly to feed or deliver the veneer to the e: rrying n'ieehanism. Willt'll eonveys the veneer to the hranding dies. Motion is eontultluieat'ed from the front of the eross h tltl to the hollow shaft hy mains of a rod 38 and an arm 3! The rod is eonneeted at its lower end with a horizontal pivot ll) of the eross head hy means of a shank or pieee rl into whieh the lower end of the rod is serewed. a jam nut 42 heing provided to prevent the rod from aeeidentally unserewing. The arm 3%). whieh extends forwardly or outwardly from the hollow shaft. is seeured to the latter hy means of a elamp 43). and its outer end l-t is hifurrated and is provided-with opposite hearings to reeeive a pin or pivot 4;). through whieh the rod 38 passes. The upper portion to of the rod is threaded to reeeiv a pair of nuts 47. whieh adjustahly position a eushion 4h on the rod. metallie washer i is interposed between the nuts and the eushion to form a hat-king for the latter.' The rod .\\'hit'h is adapted to slide through the perforation 3t) of the pin or pivot 45. ,earries a eoiled spring 51. interposed hetween the nut l2 and the pin or pivot 4:) and arranged to he compressed when the rod moves upward independently of the arm. after the latter has reaehed the limit of its upward movement. The arm is swung downwardly hy the rod 38 to feed the veneer inwardly. and the said rod forms a suhstantially rigid eonneetion hetween the feeding deviee and the gearing during sueh movement of the former. the hutfer 0I'-tllshion 48 heing in engagement with the pin during sueh movement of the feeding deviee.

The return or forward movement of the feeding deviee is elfeeted through the Spring 51. and a plurality of horizontally disposed eoiled springs 52. arranged in advance of the tubes 16. and secured at their rear ends to the same, and connected at their front ends to a transverse portion 53 of a substantially U-shaped frame 54. The tubes 16 are provided at their front sides with eyes, to which the rear ends of the coiled springs 52 are connected, and the U-shapcd frame, which is composed of two short sides and the transverse connecting portion 53, is provided at the latter with depending lugs 55, to which the outer or front endsof the springs 52 are secured. These springs 52 are distended. when the feeding device is swung inwardly or rearwardly, and they assist in returning the oscillatory feeding device to its initial position. and for maintaining the same in such position. while the veneer is being carried upward to the telescopic members. The forward or return movement of the oscillatory feeding device is limited by means of a transversely disposed buffer 56, extending across the front of the machine and consisting of a. strip of rubber, or other suitable material, mounted in the groove of a channel bar 57. The channel bar 57, which is com-posed of upper and lower sides or flanges. anda connecting portion, is provided at the said sides or flanges with segmental recesses 58, arranged at intervals and located opposite the tubes 16, and adapted to expose portions of rubber, and to arrange the metallic portions beyond the feeding device to prevent the channel bar from being struck .by the tubes 16. 1

The crank wheels rotate in the direction of the arrow in Fig. 2 of the drawings, and when the wrist pin moves upwardly at the inner or rear side of the crank wheels, the,

table is moved upwardlv and the oscillatory feeding device is moved forwardly. or in the direction of the front of the machine. The oscillatoryfeeding device is at the limit of its forward movement, and in engagement with the buffer 56. when the table is at the center of its stroke. and the wrist pin is midway between the top and bottom of the crank wheels. Further upward movement of the wrist pin carries the cu'shion'48 away from the pin or pivot 45, which is engaged and held against downward movement by the spring 51. The coiled spring 51 gradually increases in tension with the upward movement of the table, and the feeding device is held tightly at the limit of its forward movement and is caused to engage the veneer at the same point during'each operation of the machine, so that the veneer will be uniformly fed to the carrying means. The spring constitutes a yieldable connection between the feeding mechanism and the operating mechanism. while the table is moving upward independently of the said feeding mechanism.

The first half of the downward throw or movement of the connecting rod 10 returns the cushion 48 to the position shown in Fig.

2 of the drawings, and the second half swings the feeding mechanism rearwardly from the forward position illustrated in full lines in Figs. 2 and 5 of the drawings to the dotted position shown in Fig. 5. The first half of the upper throw or movement of the connecting rod swings the feeding mechanism upwardly.

The (branding, which is fully illustrated, described and claimed in the aforesaid application. occurs during the second half of the upward stroke or movement of the connecting rod and the first half of the downward throw or movement, while the feeding mechanism is at the limit of its forward Y movement.

sprocket gearing, consisting of a longitudinally disposed sprocket chain 60, and front and rear sprocket wheels 61 and 62. The front sprocket wheel 61, which is arranged on the shaft 11, is adjustably secured to a disk 63, provided with an annular series of perforations ($4 and keyed, or otherwise secured to the shaft 11. The perforations 64 are adapted to receive screws 65, which engage threaded perforations 66 of the sprocket wheel 61. The adjustment of the sprocket wheel 61 enables the feeding mechanism to be operated to feed the veneer at the proper time. Any other suitable means, however, may be employed for adjustably mounting the front sprocket gear on the shaft 11, and if desired. other gearing may be employed for communicating motion to the crank wheels.

The veneer is'conveyed to and from the branding mephanism .by means of lower front and rear continuously rotating wheels (37 and (38. arranged in transverse series and mounted on transverse shafts (l9 and 70. and cooperating with upper front and rear idlers or gravity wheels 71 and 72. The shafts 69- and 70 are journaled in suitable bearings of the sides of the frame, and they are equipped with spur wheels 73 and 7-2, which mesh with a large spur gear wheel 75, mounted on a shaft 76 and also meshing with a gear 77 of a counter shaft 78. The shaft 78 is also provided with a pulley 79, which receives a driving belt 80. extending downward through the floor to a suitable driving pulley. The machine will generally be arranged on one of the upper floors of a factory. but it may be operated at any other place, and the driving belt will be arranged to correspond to the position of the machine with relation to the driving shaft. The rear sprocket wheel 62 is mounted on the shaft 76. and the gear rotates in the direction of the arrow in Fig. 1 of the drawings. This rotates the

wheels

67 and 68 in the proper direction for carrying the veneer to and from the branding mechanism. The upper flight or stretch of the sprocket chain (it) also travels forwardly or in the direction of the front of the machine, and this secures the operation of the crank wheels heretofore explained.

The front and rear veneer. carrying wheels (37 and (98. which are arranged in spaced relation. as clearly illustrated in Figs, 13 and 4 of the drawings. extend in advance and in rear of a transversely disposed bed plate H1. andthe upper gravity wheels. which yieldably hold the veneer in engagement with the lower positively driven wheels. are journaled between

oscillatory arms

82 and 83. arranged in pairs and connected by sleeves. mounted on front and rear tr.-insverse rods 84 and H5. The gravity wheels T1 and T2 exert a sutlicient pressure on the veneer to secure a positive and rapid movement of the same through the machine, when the veneer is free to move. and they enable the movement of the veneer through the machine to be arrested duringthe branding operation. without stopping the rotary movement of the carrier wheels 7 and ('38. The tensile strength of the veneer is sutlicient to enable this result to be accomplishtal without injury to the material.

The veneer is delivered to the feeding wheels by the oscillatory feeding device, which introduces the inner end of the veneer between the upper and lower wheels 71 and UT. The veneer is gripped by the front carrying wheels with sutticient force to engage it with the suction devices. and it is rapidly carried rearwardly through the machine until its movement is arrested. The veneer is moved across the top of the bed plate, which is equipped with burners 92, and during the passage of veneer across the said plate. the sheets of veneer are first gripped by a series of clamping plungers 10b and are then engaged by a series of branding plungers 1H9. as fully explained in the aforesaid application. As soon as the veneer is released by the clamping plungers, the carrying wheels rapidly complete the movement of the veneer through the machine and discharge the veneer upon the rear table 135 having com mrtments 136 from which the veneer may be readily removed.
