To all 'whom it may concern:

Be it known that 1 HENRY W.` CARPEN- TEE, a citizen of the United States, residing at Washingtonfin' the District of Columbia, have invented new and .useful Improvements in Slat-Weaving Machines, ofwhich the following is a specification. A,

This invention has for-its general objectlto rovide' a novelmachine which shall operate 1n a thoroughly practical, feasible and expeditious manner to l'Weave slats, or thin strips of wood of deiinite lengths, whereby to form woven lathing. l

Specific objects of the invention relate to a novel shed-forming mechanism and means for operating the same; to a novel`feed mechanism for feeding the warp-strips to' the shed-formers to a novel feed-mechanism for feeding the weft-strips between the warpstrips to novel means for guiding the warpstrips into the shed-formers to novel means for securing the intermittent feed of thel warp-strips through the shed-formers after -the/ feed-mechanism has ceased to actuate the same; and, iinally, to details of construction and operation of parts, all as hereinafter more fully described and particularlypointedV out in the claims. y

In the accompanying drawin illustrating the invention, and in whichhie reference numerals indicate corresponding parts in the various viewsz--Figure 1 is a top plan view of my im roved machine Fig. 2 is a crossseotion ta en on theline 2-2 of Fig. 1; Fig. 3 is a view in front elevation of the weaving being a section on the line 3-3 of Fig.. 1, viewedin the direction ofthe arrow; F" 4 is a cross-section on an enlarged sca e, through a portion of the feed table and the shed-formers, illustrating the operation of Weaving the slats ,i F' 5 is a view similar to Fig. 4, but on a stll larger scale, omitting the supports for the shedformers, illustrating afmodification in the means for guiding the warp-strips to the shed-formers, Fig. 6 is aview in side elevamera'ls 1 indicate uprights constituting the main frame of the Weaving machine proper each of which is provided on its inner side With two slide-ways indicated by 2 and 3, respectively, said slide-Ways being preferably formed as an integral part of said uprights.

4-5 indicate, respectivel two pairsl of slide-members, each of ,whic is provided at its outer side with ides 6, which are 4adapted to engage and side in the corres ondm slide-ways'4 2-31of the uprights 1. ach o 'the slide-members 4-5 1s provided at its upper end and about mid-Way its length, respectively, with two inwardly projecting .socket-members 7, in each ofwhich is secured one end vof a bar, indicated, respectively, by the numerals 8-9--10-11, the bars of the respective slide-members extending lparallel substantially throughout the Widt of the weaving'portlon of the machine. Secured to the bar 8 of the slide-member4, at suitable intervals throughout its length, and progectin downwardly therefrom'are a series o she -formers,12. Secured oithe bar 9 of said slide-members in a correspondf respective shedormers 12 and`13 being directly opposite each other, or in vertical alinement.

throu hout the length of said bar and 'are' a1'- range 4 formers 12. In other words, the' shed- ' formers 12 and 14 work in the same vertical On the ba'r 10 of the slide-members l5 are mounted a series of shed-formels 14, which lare located at suitable Intervals to alternate with the series of s'h'ed- Y lane but have a relative staggered relation.

n the bar 11 lof said slide -members are mounted a series of shed-formers 15 which lare directly under, or in vertical alinement with the shed-formera 14, and in like manner alternate with the shed-formels 13. The opposing ends of the respective shed-formers 12 p and 13 and 14'and 15 are selparat'ed by aconsidcrable space, as moreclear' y illustrated by Fig. 4, this space bein for the purpose, as will hereinafter more fu y appear,'of provid' an entrance for the warp-strips intothe s ed- 'formers and also for providing a certain amount of lost motion to'permit the feed .of said warp'strips., 4

All of the shed-formera are4 alikein-"construction, and I have illustrated theconstruction of one of these clearly 6 and 7'. Referring to these figures, itwill be seen that said shed-former comprises a base or flanged portion 16 by means of which it is secured to its bar or support and has an enlarged bifurcated end portion affording a U- shaped recess 17. Extending transversely across this recess is a curved guard or support 18, which is for the purpose of supporting and guiding the weft-strips and preventing their ends from engaging against the edges of the warp-strips as said weft strips are being fed through the warp-strips. The shed-former being recessed Aas described, provides two pron s 19 which are the active agents in forming t e shed. The slide-members 4-5 are adapted to be alternately raised and lowered to form the sheds inthe war -strips and the machanism for accomplis ing this operation will now be described. Referring particularly to-Figs. 1, 3 and .8, the numerals 2() indicate supports, mounted at the upper ends of which are spaced, parallel rails 21,' each of which has on its inner side a longitudinally extending tongue 22. 23 indicates a bar, which is provided on o posite sides with grooves to engage t e tongues 22, and is thereby slidably mounted on said tongues. At its forward end portion, and on its under side, the bar 23 is provided with a rack-bar 24. 25 indicates a crankwheel, which may be driven from any suitable source of ower (not shown) near lthe periphery of which is pivotally secured one end of a itman 26 the opposite end of which is pivota ly connected to the rear end of the bar 23. Mounted in suitable bearings 27 beneath the rails 21, and extending at rightangles thereto, isy a shaft 28 on which is loosely mounted a mutilated gear 29, the teeth of which are adapted to be engaged and releasedv by the teeth of the rack-bar 24.

' Fixedly securedto the shaft 28 by the side of the gear 29 is a ratchet-wheel 30, the teeth of ywhlch are adapted to be engaged by a spring-controlled pawl 31 mounted on the side of the gear 29. As the wheel 25 revolves, the pitman 26 will cause the bar 23,

carrying the rack-bar 24 to be reciprocated back and forth. In the forward movement of said-rack bar, or theA movement to the left, as the parts are shown in Fig. 3, its teeth will engage those of the gear 29 and turn the latter tov substantially the position shown in said Fig. 3, after which the teeth` of said rack-barmove out of engagement-,With said gear. l In this movement, the pawl 31 simply slides over the teeth of the ratchet-.wheel 30, and the latterremains stationary. In the return, or rearward movement ofthe rack-bar, it will again en-.

gagethe gear 29 and turn the same, and in this movement the awl 31 engages a tooth of theratchet-whee 30 and causes the same to revolve with the gear 29, and thereby impart rotationl to the shaft 28. Secured on one end of the shaft 28 is a worin-gear 32 which meshes with a worin-wheel 33 secured on the end of a shaft 34.

35 (Fig. 2) indicates an auxiliary frame, in the upper part of which, opposite the shedformers, are mounted two relatively large rollers 36, 37, the upper one, 36, of which rests upon the lower', and is held in yielding contact therewith, under a greater or less pressure, by means of two arms 38, pivoted to the frame at 39 and carrying adjustable weights 40 and bearing-blocks 41 which are pressed down by said weights upon the upper side of the shaft 42 of said roller at opposite ends of the latter, as shown in Figs. 1 and 2. The shaft 34 extends throughout the entire width of the machine, and is supported in bearings 43 in the frame 35. The lower roller 37 is mounted on and flxedly secured to this shaft between the end members of the frame 35. F ixedly secured on the shaft 34, near the ends of the lower roller 37 are gear wheels 44, which mesh with smaller gear-wheels 45 mounted on a shaft 46. Pivotally secured at one end near the periphery of each gearwheel 45 is a pitnian- 47, the opposite end of which is pivotally secured to the outer end of a lever 48 pivotallynounted intermediate its ends on a rod 49 extending transversely across the machine beneath the shed-formers and secured at opposite ends in the uprights l. Only one of the gear and lever arrangements just described is illustrated in Fig. 2, but it will be readily understood that at the opposite end of the roller 37 to that shown an exactly similar arrangement is provided. The outer end of each of the levers 48 has a slotted pivotal connection with a slide-niember 4, and intermediate its bearing on the rod 49 and its connection with the itman 47, a similar pivotal connectionf wit i a slidemember 5, as shown by dotted lines, as to one set, in said Fi 2, and indicated by 50, 51, res ectively. t will, thus be seen that as the shaft 28 is placed in rotation by the rack-bar 24, as previously described, the worm-gear 32 on said shaft, meshing with the wormwheel 33 will o erate to rotate the shaft 34 and consequent y the gears 44 and the roller 37 on said shaft. The gears 44 actuate the gears 45, which, through the medium of the pitman 47, will cause the levers 48 to be rocked on the rod 49 as a pivot and thereby alternately raise and lower the two sets of slide-members 4-5 and consequently the two sets of shed-formers 12-13 and 14-15. This movement of the shed-forniers, however, as will presently appear, is intermittent. The purpose of rotating the roller 37 will also appear later.

I will now describe the mechanism for feeding the war -slats to the shed-formers: Referring to Figs. l and 2, the numeral 52 indicates a table, supported on standards 53. Said table is oblong in shape, and has one end the end of said'lowermost weft-Slat.

`formers 13 while the even numbered slats will be pressed downward by the series of shed-formers 14, and this latter is the osition of the parts shown by Fig. 4. his alternate raising and lowering of the alternate slats forms the sheds, as will be understood, and it is while the parts are in th'e position shown in Fig. l4, or the corresponding reversed osition, that the weft slats are fed into the s eds formed by the warp slats, andl the mechanism for accomplishing this operation will now be described. p

73 4indicates a receptacle which is mounted upon the upper side ofthe rails 21 and is located'as shown in Fig3 at right angles to the line of movement of the warp slats 58a. The

receptacle 73 is of a'width on its interior to snugly'receive @the weft slats 74 which are piled I'one upon the other flat wise-in said receptacle; and the latter may be made as high as necessary to accommodate the desired number of weft slats. The rece tacle 73 is about the length on its interior o aweft slat and its inner edge is located closely adjacent to the innermost shed-formers as clearly in dicatedin Fig. 1. The bottom of said receptacle is open and secured on its bottom edge, on opposite sides thereof, are two strips 75 which project slightly within the inner edges of saidl receptacle and serve' to support the slats'within the latter.

On the inner end of the bar 23 is pivotally mounted a push-finger 76 which is normally ressed upward by means of a s ring 77. his ush-iinger is located central y of the end oi) the bar23 and is in a position to press upward against the bottom of the lowermost weft slat 74 in the receptacle 73. Ir. the rotation of the crank wheel 25 after the bar 23 is ,drawn backward to the extreme limit of its movement in this direction, the push-iinger 76 will pass from underthe lowermost weft slat 74 and sprin upward against theY bottom edge of the bac wall 78 of the receptacle 73, and thus be in a position to envage en the bar 23 starts outward,\l in such. movement said lowermost -weft slat will be carried forward by the push-finger intathe longitudinal opening afforded by the'series of shedormers and between the warp'strips, which at this-moment are held in the positlon shown 'at Fig, 4, that-is', with the odd numbered slats raised and the even numberedlowered,-

or vice versa, by reason of the fact that there is no movement of the shed-formers in the forward movement of the rack bar, las previously described. Y

As thel rack bar starts on its return movement and engages' the gear 29, the shedformers and feed mechanism will be operated as already described', and owingto' the fact that the distance between lopposing shed-formers isgreat enough to allow of one shed-former of a pair moving outof engagea fraction less than four inches in each cycleI of movement, the warp slatsbeing 48 inches.

long and 13 -weft slatsbeing interwoven therewith to form al complete woven lath.

.As each warp slat is pressed downward or upward by a shed-former, its edgeiis carried sllghtl below or above the curved support 18 of t -e adjacent shed-former, so that as the weft slats'7 4 are introduced there is no possibility of their ends striking vagainst the sides of said war slats. As the woven lath passes l from the s ed-foriners it enters a longitudinally disposed guide 79, which is opened at both sides and 1s positioned on the auxiliary frame 35 directly opposite-the line of meeting ofmthe two rollers 36 and 37. These rollers rotate intermittently in unison, with the sprocket-chains 62 and at the same rate of speed as the latter, and hencewhen the feed bar 63 passes throu h the opening 64 in the table 52 and out o contact with the warp strips, said wa strips will have been engaged by thero ers 36 and 37 and the'continued forward feed of the slats through the shed-formers is then produced by said rollers. In order to provide a positive engagement of these rollers with the slats ,theirsurface may be roughened or corrugated, as will be understood, and the requisite frictional en agement can be secured by adjusting the welghts 44 on the arms 38.

80, Fig. 2, indicates a table which is adapted to receive the slats as they pass from tween the rollers 36A and 37 Referring now to Fig. 5, I have indicated a modified means for feeding the warp slats 58.a to the shed-formers. In this constructionv the table 52 is located at a greater distance from the shed-formers than is the case where the guides 72 are employed and has pivotally secured above and below each of lts openin s 71 a bar 89-90, respectively, each of w ich is pivotally secured at its outer end to the outer end of the inner prong 19 of a shed-former. Said bars are pivotally secured tol the table 52 by vhaving loops 91'formed at their inner end which enga e the eyes 92 secured on the front of the tab e table is inclosed by means of end walls 54 and side walls 55. The space between the side walls is divided up into a number of Slat-receptacles 56 by means of a series of division walls 57 arranged equi-distant and extending arallel with said side walls and each other from end to end of the table. As shown in Fig. 1, these division walls provide, in conjunction with the sides of the table, fifteen spaces, or receptacles, but a greater or less number may be provided according to the width of the weaving machine, or the width f the lath to be woven. The warp-strips, 58a, are ordinarily four feet in length, and are piled flat, one on top of the other in the series of receptacles 56, as clearly indicated in Fig. 2. The end walls, side walls and division walls of the table 52 may be made as high as desired to provide receptacles 56 accommodating a greater or less number of slats at a time. Mounted beneath the table 52 in suitable bearings and extending transverselythereof, are two shafts 58, 59, one of which is locatedat the rear end of the table and the other well toward the center thereof. On the shaf-t 58 are three sprocket-wheels 60 and on the shaft 59 three similar but somewhat smaller sprocket-wheels 61. Sprocket-chains 62 ass around these s rocket-wheels. 63 indlcates a feed-bar whic is connected to the three sprocket-chains 62 and extends transversely across the same. The peripheries of the two sprocket-Wheels 60-61 are flush with the upper edge of the table 52 so that in the revolution of the sprocket-chains 62 the feed-bar 63 will ass u on and slide over the rear portion of t e tab e.- It passes from the table through a transverse slot 64 provided therein ad'acent to the outer edge of the sprocket-w eels 61. In order to permit the feed-bar 63 to pass on to the table the rear portions of the side bars 55 and division bars 57, and the rear-end bar 54 are cut awa A at their lower edges to rovide a space 65 w ich is just wide enoug to accommodate the width of the bar 63. This space is also the exact width of a warp-Slat 58a. .It will thus be seen that with the rece )tacles 56 rovided with a number of' warp-slats that t e l Wer slat in each receptacle will rest upon the table 52 and its rear end will be exposed in the slot 65 in position to be engaged by the feed-bar 63 as the latter is brought to enter the recess 65 by the rotation of the sprocket-chains 62.

For rotating said sprocet-chains, I rovide the' following mechanism: Mounte on the opposite end of the shaft 34 to that containing the worm wheel 33 is a bevel-gear 66 which is in mesh with asimilar bevel-gear 67 mounted on the end of a shaft 68 which extends parallel to the table 62 and at its rear end is provided with a bevel-gear 69 which meshes with a similar bevel-gear 70 into the shed-formers.

on the end of the shaft 58 on which the s rocket-wheels 60 are mounted. It will tfius be seen that as the shaft. 34 rotates it not only actuates the shed-formers as before described, but through the medium of the bevel-gears and shafts mentioned, actuates the sprocket-chains 62 which latter, through the medium of the feed-bar 63 operates to feed the lower slat in each of the receptacles 56 toward the shed-formers.

At the forward end of the table the end wall 54 is provided with an aperture 71 opposite each of the receptacles 56 to permit the slats in said receptacles to pass out of the same Secured on the forward end-wall 54 of the table are a series of rectangular outwardly-Haring guides 72, one of which is located opposite each aperture 71., and each guide being substantially the width of a -`warp-strip. The guides 72 are for the purpose of directing the slats'into the shedformers, and are outwardly-flaring to ermit the up and down movement of the s ats in forming the sheds as will more clearly appear from 'an inspection of Fig. 4 of the drawings.

ln the operation of the device thus far described, and assuming the relative positions of the slide-members and shed-formers to be as shown in Figs. 2 and 4, the rack-bar 24 in its return movement engages the gear 29 and revolves the shaft 28, which through the mechanism described will actuate the shed-formers. The slide-members 4 being in uppermost position will begin to descend, carrying with them the shed-formers 12 and 13, and the. slide-members 5 being in `their lowermost position will begin to rise carrying upward the shed- formers 14 and 15. At the same time the sproc" et chains 62 will be revolved from the shaft 24 as previously described and the feed-bar 63 engaging the rear ends of the lowermost sl'ats in the receptacles 56 will begin to feed them forward and out through the respective guides 72. Assuming the slats in each alternate receptacle 56 to have odd numbers and those in the intermediate receptacles to have even numbers the rela'tive arrangement of the parts is such that as the Vspaces between the two sets of shed-formers come into alinement o posite the guides 72, the Warp slats 58 wil have their forward ends moved .into these spaces, the odd numbered slats passing between the series of shed-formers 12 and 13 and the even numbered slats between the series of shedformers 14 and 15. In the continued downward movement of the slide-members 4, the lower shed formers 13 will move out of contact with the odd numbered slats and after a slight further movement the shedformers 12 will engage the upper sides thereof and press them downward, while as to the shed formers carried by the slide-members 5, the upper shed-formers 14 will be moved out 3. A Slat-weaving machine embodyingtwo which is further provided with recesses 93 toried between'thewarp slats and thus serve in a measure to uide them in their forward movement. T e lower bars in moving upward will also ass between the warp strps which have een pressed downward an serve ,to guide themas clearly indicated in the drawinv.

, By my machine woven lathing can be manufactured continuously and expeditiously, f

and the laths will be uniform in character, as the mechanism described insures cer- 'tainty and uniformity'of action and the liability of breaking, splitting or cracking the laths is reduced to the minimum.
