Specification of Letters Patent.
Patented Nov. 6, 1917.
Application filed May 8, 1916. Serial No. 96,259.
To all whom it may concern:
Be it known that I, Suns M. Form, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Machines for Making Lath-Board, of which the following is a specification.
his invention relates particularly to a machine for making lath-board wherein the lath-board, preferably of water-proofed fibrous material, is crimped into a corrugated 0r dove-tailed shape, and means are also provided for running a stiffening wire through the crimped stock.
One object of my invention is to provide means for crimping the material to be made into lath-board into a corrugated or dovetailed shape, and provide therewith means for stripping the material so formed from the formingmeans as soon as the form has been established.
Another object of my invention is to make the stripping means of such a design that they will hold the material into the form in which it is pressed, and tend to brin it from a corrugated shape to a dove-tailed shape.
Another object of my invention is to vide means for crimped into a dove-tailed shape.
Another object of my invention is to provide means for setting the corrugations formed into a dove-tailed shape after they have come from the corrugating rolls.
Another object of my invention is to provide a guide for the reinforcing Wires in such manner that the formed stock may be fed on to the wires, without liabiltiy of the wires buckling.
lVith these and incidental objects in view the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawings which accompany and form a part of this specification.
In the drawings Figure 1 discloses a side elevation partly in section of the preferred,
progathering the material corrugated shape into a form of my improved machine with i the means for guiding the reinforcing wires omitted.
Fig. 2 is a plan view of the same. Fig. 3

Fig. 8 construction of my improved machine with the means for guiding the reinforcing Wires Fig. 9' is a plan view of the same.
Fig. 10 is a side elevation of an alternate construction of the rocker bars shown in Figs. 8 and 9, and Fig. 11 is a plan view of the same.
Fig. l2is a still further modification of the rocker bars shown in Figs. 8 and 9, and Fig. 13 is a plan view of the same.
The water-proofed paper or whatever material is to be used in making the lathboard is taken from the roll 1, Fig. '1, in which it is ordinarily shipped.
The paper 3 passes through the guides 4 of the crimping rolls 5 and 6, which are corrugated shape, as shown at 8, with spaced faces 9 and webs 10 connecting the faces 9. I employ preferably six pairs of guides 4, as better shown in Fig. 2, and these guides pass through slots in the cleats 7 and grooves in the rolls 5 and 6 in the slats ll, and
and also through slots support and guide the formed paper through process.
As the distance between the upper and lower sets of guides is just 'sufficient to ass therein between the corrugated lath-board, the material is stripped from the rolls 5 and 6 as soon as formed.
The material now in a as shown at 8, Fig. 1, gathering mechanism.
This gathering mechanism comprises a pair of shafts 12 and 13, each of which carries sprocket wheels 14- and 15'at either end of the shafts.
A similar pair of shafts 16 and 17 also carry a pair of sprocket wheels 18 and 19 at either end of each shaft.
corrugated shape, passes toward the the entire forming of the paper,
'11 on the chains 20 A pair of chains 20 carried by the upper set of sprocket wheels, and a similar pair of chains 21, carried by the lower set of sprocket wheels, carry the slats 11, which are integral with, or rigidly attached to links of the sprocket chain.
The gathering mechanism is preferably geared to the rolls 5 and 6, so that the peripheral speed of the travel around 15, is the same as the peripheral speed the rolls 5 and 6 carrying the paper, hence the slats will register with the corrugations as shown at 8.
It is evident that as the sprocket wheels turn in the direction of the arrows 22, when the slats 11 leave the sprocket wheels 14 and 15 and travel in a straight line on the chain, their speed is retarded to that of the speed of the sprocket wheels 14 and 15 at their itch diameter.
It is evident, therefore, that as the slats and 21 register with the corrugations as at 8, and then slow up their speed, the paper must be pressed together and the result is the dove-tailed form, as shown at 23, the guides 4 preventingany buckling of the paper.
It is evident that as the slats 11 closely fit the spaces between the faces 9 of the dovetailed board, it would be impossible to have these slats roll out of the spaces, as they rolled into the spaces while the materialwas still corrugated, hence the distance between the centers of the shafts 16 and 17 is increased over the distance of the centers of the shafts 12 and 13, so that when any individual slat has reached the center line of shafts 16 and 17, it has been withdrawn entirely from the spaces between the faces 9 of the dove-tailed lath-board. This couldv of course be accomplished by using smaller sprockets on the shafts 16 and 17 with the centers in line, but I prefer the construction as shown.
The slats 11 have not only the slots 24, Fig. 2, cut therein, through which the guide wires pass, but also a series of slots 25 for the reinforcing wires 26. The reinforcing wires which are held and guided in a manner to be described hereafter have their forward ends pointed, as shown at 27, Fig. 1, so that the slats 11 carrying the dove-tailed board will force the webs 10 on to the reinforcing wires 26, and carry the paper backwardly in the direction of the arrows 22 threaded on to the reinforcing wires 26.
Guides 28, Figs. 3 and 5, are provided in which the reinforcing wires 26 rest during the threading operation.
A series ofrollers 29, suitably mounted on the frame 30 of the forming machine itself, and also on standards 30 beyond the wire threading end of machine, as shown in Fig. 3, serve to carry the guides 28 and allow and press it downwardly,
them to be pushed rearwardly by the dovetail shaped lat -board, as the wires are threaded therein. I
In starting the operation, the wires would be placed with their pointed ends at the point 27, and the forward end of. the guides 28 would be positioned at the point 32, Fig. 1.
The wires themselves are held by suitable clamps 33, Fig. 3, and the guides 28 would be forced backwardly from under the reinforcing wires, leaving them reinforced by the webs 10 of the paper over that portion of the wires threaded through the lathboard.
As an alternate construction, I take the paper 3, Fig. 8, pass it through rolls 5 and 6, with cleats 7 as already described, and have similar guides 4 carrying the material entirely through the machine, as shown in Figs. 8 and 9. 7
Instead of the gathering means, as shown in Figs. 1 and 2, I utilize a pair of rocker bars 33, Fig. 8, driven by connecting rods- 34 from the pinions 35, which in turn are driven by gears carried by the rolls 5 and 6.
The resultant oscillatory motion is timed through'the gearing, so that when the face 36 travels in an anticlockwise direction, it will strike points 37 of the corrugated paper while the face 38, also traveling in an anti-clockwise direction, will strike points 39 of the corrugated paper and :force these portions of. the paper upwardly.
On the return stroke of the oscillatory motion, the surface 36 will strike points 40,
while traveling in a clockwise direction, and
the face 38 will strike points 41, also while traveling in a clockwise direction, so that by the action of the rocker arms, the corrugated shape is forced into the dove-tailed v shape, shown at 42.
I prefer to use with this method a pair of squeeze rolls 43, although they are not absolutely essential. v
With this construction I utilize a pair of threading rollers 44 having slats 45 thereon, so spaced, and the rolls so geared that these slats will register with the spaces between the surfaces 9 of the dove-tailed paper. These slats have slots to receive and support the reinforcing wires 26 and they are threadin the position of the ones 13o shown on the standard 50, Fig. 6, but when the corrugated paper passes over them the forward end is cammed by the paper itself, and they assume the position of the ones shown on the standard 49, Fig. 6.
With the construction shown in Figs. 6, 7, 8 and 9, the guide wires would pass through the rolls and slats used in the forming of the dove-tailed lath-board, and the threading means in the same manner as already described with respect to the machine shown in Figs. 1 and 2.
simpler form of rocker bars 33', Figs. 8 9, is shown in Figs. 10 and 11, in-which the shafts 51 and 52 carry slats 53 and 54, respectively, driven by rolls 5 and 6, Figs. 8 and 9, at such speed that the slats 54 will strike points 55 of the corrugated paper, and slats 53 will strike points 56 of the'corrugated paper, thereby forcing the corrugated shown at 57.
A further modification for attaining the same end is shown in Figs. 12 and 13, in which the rocker bars 33, Figs. 8 and 9, are replaced by slats 58 and 59, and 65 and 66, Figs. 12 and 13.
A shaft 60, Fig. 12, has keyed thereto a series of sleeves, each carrying the sectional slats 58. Journaled on the shaft 60, a series of sleeves 61 carry slats 59. and these sleeves are driven by gears 62 integral with the sleeves 61, by pinions 63, driven in turn by the chain of gears 64.
The lower shaft carry slats 65 and 66, 59, respectively. Y
It is evident that with the series of slats 58 and 65 driven in an anti-clockwise direction, while the series of slats 59 and 66 are driven in a clockwise direction, and the gearing of the shafts 60 and 60, and the rolls 5 and 6 of the proper ratio, the slats 58 will strike similar to slats 58 and points 67, slats- 59 traveling in a clockwise direction will strike points 68, while slats 65 traveling in an anti-clockwise direction will strike points 69, clockwise direction will strike points 70 of the corrugated paper, thusforming it from a corrugated shape, shown at 71, to the dovetailed shape, shown at 72.
With any of the methods as shown, the guides 4 run entirely through the forming and threading portion of the machine, and I prefer to have the guides narrowed at the points in the forming machine where the forming of the lath-board is changed from a corrugated to a dove-tailed shape, so that while the lath-board fits the guides closely in its corrugated shape, it will also fit the narrowed guides closely in its dove-tailed shape.
In fact, I am able by using a sufficient number of guides,
so as to create a considera pair of shafts shape into a dove-tailed shape, as
also carries a similar. a set of keyed and journaled sleeves, which I tions more closely together,
able amount 0 friction, to form the lathboard from a corrugated shape "to a dovetailed shape merely by narrowmg the ides, but this method requires agreat dea more power, and is less satisfactory than my pre ferred construction, although it is" covered in the scope of this invention.
While I have described my invention and illustrated it in one particular design, I do not wish it understood that I limit myself to this construction, as it is evident that the application of my invention may be varied in many ways within the scope of the following claims. Y
