Application led March 9, 1909. Serial 110.482,35.

citizen of the United States of America, re. siding at St. Joseph, in the county of Buchanan and State of Missouri, have invented new and useful Improvements in Apparatus for Weaving Veneer Strips, of which the following is a specification.

This invention relates to an apparatus or machine for weaving strips of veneer or the like together at right angles to each other for the production of a blank or body of material adapted to be used in the manufacture of baskets and other articles.

The object of the invention is to provide a. machine of this character whereby the strips may be formed from rolls of the sheet veneer and then assembled or woven in a rapid and effective manner, the operation being automatic in entirety so as to reduce to a minimum the number of attendants required to run the machine, thus insuring economy in the gmanufacture of goods of this class.

With these and other objects in view, the invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which v Figure 1 is a top plan view of the machine. Fig. 2v is a vertical transverse section on line 2 2 of Fig. 1. Fig. 3 is a vertical longitudinal section along the line 3--3 of Fig, l. Fig. 4 is a top plan view of a portion of the frame and gearing for the feed rolls and associated mechanism for operating the knives. Fig. 5 is a section on line 5 5 of Fig. 4. Fig. 6 is a side elevation of the feed carriage. Fig. 7 is a longitudinal section through the same and a portion of the feed belt or apron. carrying the fingers whereby the transverse strips are fed in the weaving operation. Fig. 8 is a detail longitudinal section through the outer ends of the delivery table and carriage, showing the clamping bar on the carriage retracted to release the woven blank. Fig. 9 is a fragmentary detail View of one of the clamping bars. Fig. 10 is a section'through the pulley and clutch gearing of the mechanism for operating the sliding feed bar. Fig. 11 is a section on an enlarged scale on line 11-11 of Fig. 1. Fig. 12 is a detail view of the carriage feeding and releasing devices of the weaving mechanism. Fig. 13

is a section on the line 13-13 of Fig. 4.

Referring to the drawings, the letter A designates a suitable supporting frame, havgles to each other, and a portion A3 connecting with the inner end of the portion A and in longitudinal alinement with the portion A2, as shown.

J our'naled in suitable bearings on the outer end of the frame section A is a shaft 1 for supporting a roll 2 of sheet veneer, and also journaled 1n bearings at the inner end of said frame section are feed rolls 3 and 4 arranged one above the other, and adapted to grip and feed the free end or portion of the veneerfrom the roll forwardly to a vertically reciprocating cutting knife 5 mounted upon a transverse supporting bar 6 adjacent said feed roll. This knife is moved up and down at timed intervals to sever the eXtreme free portion of the end of the sheet of veneer into strips, which drop upon a feed table hereinafter described, the free edge of the sheet being supported beyond the rolls for the effective action of the knife thereon by a rigid cross bar 7. The knife carrierpbar 6 is fitted to slide in slots 6a in bracket extensions A4 at the sides of the frame portion A ,in each of which slots is an expansion s ring 6b which impels the'bar andknife own- Ward. The ends of the bar project beyond the sides ofthe frame portion A andare karranged to be engaged and lifted against the resistance of the springs by cams 16, each of which is mounted upon a stub shaft 6C, on which is also xed a spur gear 6. The wings ofthese cams alternately engage and elevate the cutter bar, thereby compressing the springs, which upon the release of the bar by the wings force the bar downward so that the knife will sever the underlying portions of the veneer sheets.

ing portions A and A2 arranged at right anf Mounted for a sliding or reciprocating movement on the frame portion A is a feed table 8 comprising a series of transverse bars or'plates l9 united at their opposite ends by longitudinal strips 10, which are formed vwith outwardly extending guide flanges 11' to run upon guides or track rails 12. The cross bars or plates 9 are spaced to provide intervening slots 13, and each is formedv with an upwardly extending longitudinal rib 14, whereby a series of longitudinal pockets or esmas ing fingers 48 'which are properly spaced to project upward through they longitudinal slots 13 in thevtable 8 when vthe latter has been fed forward to thelimitof its move- 'ment and its pockets 15 are lilledwithvth strips 44. It will be understood that through `the intermittent action of the drive mechanism, the table 8 will be intermittently fed forward -a distance equivalent to the distance between adjacent pockets 15, when the mechanism will come to a stop, at which time the cutting knives will be released by the cams and projected by their springs, thus forming the strips, after which the table 8 will again 'move forwardlyand the operation Will be repeated, and that during this intermittent movement of the tableA 8 the parts of the weavin mechanism including 4the cutting :means or forming the transverse strips will be operated in timed relation therewith, so that while a set of the strips 44 is being prepared for use the Weaving mechanism on the frame A2 will be in operation to interweave -the strips 44 previously prepared with the strips 45 constantly produced by the action of the cutter35.

Mounted on a shaft 49 below the frame portion A2 is a double ulley 50 having portions 51 and 52 of di erent diameters and provided at one end with a clutch member 53 adapted to be en lged by a grooved clutch collar 54 sli ably and rotatably mounted on said shaft and engaged by the forked end of a pivot lever 55, the opposite end of which carries a pin 5,6'movable 1 n the longitudinally slotted lower end 5 7 of a rod 58, thus forming a sliding or slip joint connection between said lever and rod. The upper `end-of the rod 58 is connected to a crank or.y wrist pin 58 on a crank gear 59 which meshes with a pinion 60 rigidly mounted on the -same shaft. as a gear 61 which meshes with the gear 21 on the roll shaft 3. As the shaft 3 rotates in feeding the veneer from the roll 2 forward for the formation of the strips 44, the gear 59 is rotated through the intervening train and slowly elevates the crank in 58a, thus drawing up upon the rod 58, whlch is elevated until the lower portion of the slotted end thereof' engages the pin 56 and trips the lever 35 to throw the clutch member 54 into engage-- shaft by a belt 62. lVhen the pin 58a passes Abeyond center at the highest point of its path of 'travel and again begins to descend, the reverse operation ensues, the clutches remaining in gear until the upper end of the slot 57 engages the pin 56 and trips the lever in`the opposite direction, and thereby throws the clutch' 54 out oflengagement with the clptch 53 and releases the'pulley50. Wound around the portion 52 of the pulleyv is a cord or cable 63vwhich extendsin theform of a` loopy around suitable superposed guide pulleys 64 and 65`arran ed respectively upon the frame portions A A3 and A2 and connected at its opposite ends' to af lug 66 depending from the bar 47. A rope orcable 67 is fixed to and ada ted to wind upon the ortionV 51 of the pu ley 50 and carries at lts free end Aa retracting weight 68. Thel gear 21a is' so proportioned to the gear 59 that the table 8 is allowed one completey for- Ward movement to lill all the pockets thereof'with thestrips 44 while the pin 58a is moving from its highest toits lowest point and up again, so that while said table isv intermittently feeding outward the rod 58 will make one complete operative movement and at the time the table is filled and completely projected the clutch 54 will be thrown into action. By this means the pulley 50 will be rotated to. move the cable on from said table into the pockets 29 of the stationary table on the frame section A2. At the instant' the strips pass from the feed table to the stationary table, the clutch 54V is disengaged fromthe gear 50, whereupon the weight 68 quickly retracts the bar 47, and as soon as the fingers 48 are released fromy engagement with the table 8 the latter isretracted by the Vweight 23 in readiness for a repetition of the operation above de scribed.

The frame section A2 is'provided at its outer end with a receiving tray or table 69 extending from a point adjacent the outer end of the stationary table and adapted to receive the completed mats. Mounted `on said frame section is a feed carriage comprising a pair -of rack bars"70 slidably supported upon the side bars of the frame sec-v tion by sets of hangers 71 and 72 and connected for movement in unison by suitable cross bars (not shown) and the cross elements of the mechanism hereinafter described.

'This carriage is provided at its outer end sitions when the tag is at the limit of its inward and outward movements. At the innen end of the carriage -above and below the `plane of the stationary table ofv the clamp said strips during a portion of the ,be depressed by springs .90 in ratus.A

frame section A2 are arran d transverse rock shafts 80 and 81, whic thus extend transversely above and below said table, and these shafts are respectively provided with sets of .forwardly and rearwardly projecting radial fingers 80"L and 80". and 81 and 81", the forwardly and rearwardly projecting fingers of each shaft alternating in arrangement with each other. i On the ends of said shafts at one side` of the table are intermeshing segments 82 and 83, and connected with the shaft' 80 vis a crank arm 84 connected by a link 85 with a crank pinion 86 meshing with rack teeth 87 formed on the upper edge of the adjacent side bar ofthe frame section, by which in the travel of the carriage the shafts will be actuated.

Mounted for sliding movement in slotted guides 88 on the sides of the frame sections is a transverse clamping bar 89 adapted t0 said guide to clamp the strips 44 and 45 during the intermittent feed movements of the carriage., so that the strips 45 fed forward by an accelerated movement, as. hereinafter described,

may be successively held for the close weaving of the strips 45 in themeshes formed by the strips 44. The lower edge of this bar is' provided with transverse notches 91 in alinement with the slots 27 for the passage of the fingers of the weaving belt, hereinafter referred to, and the ends 92 of said bar roject beyond the slotted guides and are eveled for engagement with controlling cams 93 mounted ona transverse shaft 94 journaled in bearings on posts or standards A6 forming part of the frame section A2 and carrying pinions 97. The cams 93 alternately elevate and permit depression of the ar 89 to permit feed of the strips and to feeding movement the distance between meshes of the strips 44 for the effective forward feed of the strips 45 and the closing of the meshes to form a tightly woven article. A-shaft 98 is journaled in bearings on the standard Ax and carries pinions 99 meshing with the pinions 97, and said shaft also carries at one end a pulley 100 driven by a belt 101 from a drive pulley 102 on the shaft 36d. Mounted on said shaft 98 is a tilting frame comprising side bars 103 and 104 and a transverse rod or shaft 105, the latter carrying pinions 106 meshing with rack teeth 107 formed on the lower edges of the side bars of the carriage, by whichv the latter is fed outward in the-operation of the appa- The side bar 104 of thev said tilting frame is provided with contact portions 108 and 109 beveled or lotherwise suitably formed for engagement by trip arms 108 and 109a on the adjacent side bar of the carriage. Also projecting from said side bar 104 is a lug 110 adapted to engage a fixed retaining spring 111, and, by frictional contact therewith, to

hold the tiltingframe or down. When the tiltin frame is tilt up, as ,shown in Figs. 6 and 7, the inions 106 mesh with the rack bars 107 to eed the carriage outward through the action of the gearing. When the carriage reaches the limit of its outward movement the arm 108'* on the carriage engages the contact portion 108 of the Swingin frame and swings the same upward, thus t rowing the shaft 105 downward and movin the pinions 106 out of engagement wit the tilted u racks 107, leaving thecarriage free to be retracted. vWhen the carriage reaches the limit of its inward movement, the arm 109* engages the contact portion 109 and throws the swinging frame up again, thus brin 'ng the gears 106 into engagement with the racks y 107 for the subsequent feedk movement of the carriage. A retracting weight 112 is provided to return the carrlage to normal i'position vand isconnected with one end of a rope ory cable 113 passing around a guide pulley 114 on the frame and connected at its opposite end with the opposite end of the carriage. Arranged below the table on the frame section A2 1s an endless belt 115v comprising chains 116 connected by cross slats 117, which chain's pass around sprocket wheels 118 on shafts 119. Pivotally mounted upon the slats of this belt are series'of transverse weaving fingers 112a normally Aso maintained at a right angle to the belt by l springs 113. The fingers upon the upper strips of the belt are adaptedl to move through the slots 27 in the stationary table and engage and feed the cross strip 45 forward. 'The shaft 19 is disposed below and adjacent the inner end of the tray or table 69 against the inner edge of which. the fingers 112 abut at the limit of their outward movement. When the fingers pass downward around the outer sprocket wheels 118 and become a portion of the return stretch of the belt, they are permitted by their springs 113 to-swing rearwardly and' pass without interference beneath said receiving table. The outer shaft 119 carries a pulley 120 connected by a belt 121 witha pulley 122 on the same shaft on which the pulley 100 is mounted, by which motion is transmitted to the belt. The gearing for driving the belt is so proportioned as to cause the belt to have a faster feed motion than the carriage, by which an interweaving ofthe strips 44 and 45 while they are progressively feeding forward in an intermittent manner is effected.

The operation is as followss---After the longitudmal series of strips 44 has been fed from the table 8 to the stationary table on the section Azthrough the action of the feed bar 47, the mechanism comes into action to cause the bars 74 to clamp the outer free ends of said strips against the cross piece 73,

and at this-time the cutter `35 begins to sever the strips 45 from the sheet of material strips 45 are'successively rformed and deposlted upon the inner ends of the ribs 28 of the lstationary table, the carriage begins to feed forwardly and is intermittently moved each time the distance determined proportionately to the distance between the meshes of the proposed fabric. As the carriageis thus operated, the shafts 80 and 81 are rocked to deflect the strips 44 alternately up and down for the production of the meshes to receive the strips 45. Through the action of the pinion 86 the deflector shafts alternately rock in opposite directions. When the shaft 80 is rocked in a forward direction the shaft 81 will be rocked reversely, so that the fingers 80HL and 81b of said shaft will be respectlvely moved upward and downward to correspondingly depress and elevate the adjacent portions of the alternate strips 45, thus crossing said strips to produce the meshes, and upon the reverse movements of said shaft the corresponding strips will be deiiected in the opposite direction, so that each strip 44 will be alternately deiected upward and downward. The inner ends of the strips when thus deflected u and down will form Haring entrances in si e elevation for the passage of the strips 45 between the same. Hence it will be understood that the fingers 112 of the feed belt will push the strips 45 between the deiiected portions of the strips 44 and first loosely weave them together, as illustrated in Fig. 7 The table has an intermittent forward or outward feed motion, and the belt a corresponding motion, but as the fingers 112 through arrangement of the gearing having an accelerated or faster motion than the table, it will be understood that they force the strips 45 between the strips 44 at an acceleratedspeed, and

Aconsequently gradually tighten the meshes and bring the strips 45 close together'for the production of a closely woven article. The bar 89 successively clamps the strips in transverse alinement with the meshes as they successively come thereunder, thus preventing the meshes from becoming loosened, and

.at the same time preventing the feed fingers from forcibly projecting the loosely woven fabric forward, thus allowing strips 45 tobe feduntil they are brought closely together and the meshes closed. This operation continues until the strips 45 are woven at close intervals with and throughout the length of the strips 44, resulting in the formation of a complete mat, at which time the carriage will have been fed outward tothe limit of its feed movement, when the arm 108 will actuate the tilting frame to throw the pinions 106 out of action, while the bar 72 will engage and be retracted by the cams 79, thus rfreeing the completed mat which .drops .upon

the table l69 from which it maybe removed and the free ends of the strips74A suitably secured to hold the series of strips permanently woven. Upon the retraction of the carriage by the weight 112, the arm` 109 strikes the tiltingframe and restores the carriage feed gearing to normal position. During rthis feeding movement ofthe carriage and while the weaving operation is going on, the feed table 8 is again being filled with strips, which, upon the return of the carriage to normal position, are fed into the pockets of the stationary carriage on the frame section A2, whereupon the operation of forming the cross strips and weaving the strips into the succeeding mat is begun.

As before described, the operation of the gearing throughout is intermittent and the partsV are constructed, arranged and proportioned to act at timed intervals throughout, thus insuring a complete automatic action and reducing the number of attendants required to operate the machine to a material extent.

By means of a machine constructed as described, a large number of mats may be made during the working period each da and these may be employed in the manu acture of baskets and many other articles.
