SHlNGLE-SAWING MACHINE.

SPECIFIGATIQN forming part of Letters Patent No. 272,316, dated February 13, 185 3.

Application filled October 27, 1881 (No model.)

To all whom it may concern:

Be it known that I, WILLIS J. PERKINS, of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new -and useful Improvements in Shingle-Sawing Machines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a partof'thisspecification. r t 7.

My invention relates to an improvement inshingle-machines, the object of the same being to provide anarrangement of parts whereby a coursing line or lines are automatically marked or printed on the shingles while the carriage is in motion.

A further object' of my invention is to provide an arrangement of parts whereby the coursing line or lines so marked or printed on the shingles being sawed shall be the same distance from the butt thereof, irrespective of the length of the bolt,

A further object of iny invention is to provide a cheap, simple, and light-running and durable slide-bearing for the carriage, that can be easily replaced at a slight cost when worn, and one that requires less oiling than the ordinary metallic hearing so commonly used on shin gle-machine carriages.

A further object ofmy invention is to provide an arrangement of parts whereby, instead of the carriage being raised vertically by passing over lumps of sawdust compressed on the track, which oausesimpert'ections in the shingles, it is moved horizontallyin itssame plane.

A further object of my invention is to pro vide simple and inexpensive means for tightening the driving-belt without disconnecting the parts or stopping the machine.

With these ends in view my invention consists in certain details in construction and combinations of parts, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is r a plan view of a shinglemachine patented to me January 11, 1881, numbered 236,620, 50 (the mechanism for reciprocating the carriage being removed,) embodying my present improvements. Fig. 2 is a longitudinal section-- al view of the same. Fig. 5 is a transverse section through the lines at a: of Fig. 1. Fig. 3 'is a detached view of one of the brackets K. Fig. 4 is a plan view of the under side of the carriage. Fig. 5 is an enlarged sectional view of the inking-rollers and pots. Fig. 6 is an enlarged plan view of the slide-bearin Fig. 7 is atransverse section of the same. Fig. 8 is an enlarged view showing the manner of tightening the drive-belt, and Fig. 9 is an enlarged view showing the means for automatica lly regulating one ink-pot.

A represents the frame of the-machine, hav- 6;, ing. the verticalsaw-arbor B journaled thereto, which latter is provided on top with the circular saw (J, adapted to be driven by any. suitable belting.

1) represents the tiltways, and E the carriage, which, together with the parts above referred to, are in general structure (excepting some details in the carriage) like those shown, described, and claimed in the patent before ,ret'erred'to, and require no special mention 7 5 here, except to give a correct understanding of the case, together with the combined operation of the marking device and shingle-machine.

The head-block F can be rigidly secured to So the sides of the carriage, as shown in the drawings; or can beadapted to move horizontally simultaneously with the dog F, as shown in Patent No. 236,620. The dog F is connected with the rock-shaft G by the links a and knuckles a, and is provided on its under side with the bar H, adapted, in conjunction with parts to be hereinafter explained, to automatically regulate the position of one pot containing the marking material and rollers, so that 0 the coursing-mark will be at a predetermined and regular distance from the butt of the shingle, irrespective of irregularities in shape of the shin gle-bolt.

On the front side of the cross-girt I, to which 9 5 the vertical] y-adjustable standard J, which supports tilt-table D, is secured, are two or more vertically-adj ustablebrackets, K, provided on top with the oblong slots, in which the frame L, secured on the .top thereof, is horizontally 10o adjusted. This frame L is provided with upturned sidesr-having grooved inner faces, in

which the pots containing the marking material and rollers are placed. When the headblock 1* is rigidly secured to the carriage, as shown in the drawings, the pot on that side of the machine can be rigidly adjusted in the fratne. at a predetermined distance from the head-block by the set-screw 0; but when the head-block is made to move simultaneously with the dog F suitable arrangement can be made to move the pot in the same direction an equal distance. These pots in and m are provided with flanges (Z, adapted to enter the. longitudinal grooves d in the sides of the frame to be guided in the proper transverse direction thereby, and are internally divided into three compartments, the middle and largest compartment, 6, communicating with the two end compartments, 0, by vertical. openings, through whit-h the ends of the inking and marking shafts N )1 pass. Each end compartment is provided with a vertical stud rising from the bottom of the pot, around which a spiral spring is placed and held in position thereby for supporting the bearing of the inkingshaft. Thisinking-shaftNis provided with as many inking-rollers as the marking-shaft N hasmatking-rollers, and themarking-rollers are; adapted to rest on the inking-rollers, which are composed of any suitable material, and adapted to be continuously fed with the marking material as the rollers are revolved, which is caused by the contact of the shingle-bolt on the marking-rollers. The peripheries of the markingwheels or rollers f rest on the peripheries of the inking-wheels f, as before stated, and the upper edges of the said markingwheels project thronghslits in the coverof the pot. The two pots are secured to the crossgirt I, (orany other suitable support.) just ahead of the tiltwa-ys D and under the saw 0, the rollers f being on a line a trifle above the top of the tiltway. Now, if the shingle-bolt is shoved off the end 0! the tilt-ways against the saw, it is evident that the under side of the same must come in contact with the rollers f, and depress them even with the line or top of the tiltway, and by the frictional contact between the bolt and rollers cause the latter to revolve in the direction of travel of the bolt, and consequently leave a line or lines on the under side of the bolt. The pots are filled with ink or any other suitable marking material nearly on a level with the top of the rollers f, and it lollows that when the roller fis caused to revolve by frictional contact the rollers f are also caused to revolve in the ink,

and the rollers ftake up a sutticient quantity of ink from the roller f and deposit it on the shingle-bolt while the latter is being moved toward the saw.

Instead of having an inking and marking shalt, as shown in thedrawings,asinglemaiking-shaft may be used instead; but the construction shown allows a larger supply of ink to be. placed in the pot within reach of the rollers, which obviates the delays incident to refilling; and instead of using marking-rollers at all, scoring-knives can be secured in the same or in any other desired manner, and be operated in the same way tocut. or score marks on the under side of the bolt; but I prefer to mark them with some sort of coloring material, as cutting or scoring the shingles leaves an aperture for the entrance of air and water, and the scored portion is consequently caused to decay before the remaining portion of the. shingle.

In shingle-machines the dog and head-block are always parallel but the shingle-bolts are not always so, but do not vary over one-half an inch. The pressure of the saw in cutting always tends to bring the end of the bolt that comes next to the head-block parallel with it. Consequently the ink-pot on that end of the bolt can be stationary and always make the marks parallel to that end of the shingle. With the dog end of the bolt it is different, as that end of the bolt is notalways parallel with the do". Thereforeit is evident that in order to make the marks parallel to the butt of the shingle the ink-pot on that sideofthe machine must follow the end of the bolt. To accomplish this I connect the pot M by the rod 9 to the slide 0, which latter is supported on a table similar to that which supports the ink-pots. This slide 0, with the movable ink-pot M, is partially controlled by the dog through the rollers IL, h, and ]L2, the large roller It being journalcd on the slide and adapted to' engage with the end of the shingle-bolt on its side of the machine. The roller It is also journaled at a point abo e the roller h to a stud secured to the sliding frame or table 0, and is adapted to bear on one side of the rod or bar H under the dog F, while the roller h ,journaled on the spring-actuated arm 1L3, bears on the opposite or inner side of the said rod. By means of this spring-actuated arm hand roller h the roller h is constantly forced outward beyond thedog for half an inch or more, and when the shinglebolt is dogged the, said roller It, being in advance of the dog, is forced inward even with the dog, carrying with it the slide 0 and pot M. Now, the roller IL has also receded from the rod, and the spring It is brought into greater tension,which presses thelai gerolleragainst the end of the bolt, and thereby causing its connected ink-pot to keep parallel with the bolt. If the shingle-bolt should be put into the carriage with its shortest end toward the saw, the large roller h at the starting will extend out from under the dog. but gradually roll up the incline as the bolt; is moved forward, thereby causing the marks to be parallel with the butt of the shingles.

By the above improvement I perform the two operations of cutting and marking the shingles at the same time, and as it practically requires no extra labor or attention to revolve the roller Nand N, I have increased the market value ot' the shingles without decreasing the capacity of the machine or adding to their cost, except for ink and the first cost of the marking device.

The head-block F (shown in Figs. 1, 3, and 4,) is forged from a singlepiece ofsteel, and is of such shape as to 1mm an inclined plane, (shown in Fig. 3,) which assists in placing the shingle-bolt on the tilt-table, and by its peculiar shape directs a portion of the flying sawdust away from the sawyersta'ce, and also 'prevents it from lodgingon the machine.

The second part ot my invention consists in providing a substitute for the ordinary metallic slide-bearing so extensively used, and Vl hich requires constant attention to keep well oiled. Experienee has taught us that there are decided objections to the use of metallic slidebearing on shingle-machine carriages, owing to the finedustand grit constantly flying about, that soaks up the oil, making the carriage run hard. It is thepresent practice to oil the slide about once every fifteen minutes; but by my inipiovement l have reduced this to about once an hour, and saved nearly twenty-five per cent. of the friction by substituting lignum-vitee slides P for the metal slides.

The method of attachingthe wood P to the carriage is as follows:

P represents a metallic corner-piere, secured to the under side ot'the carriage, and provided with the uprights 6, having horizontal journalboxes t" for the rock-shaft G. I have cored out a rectangular space in the corner pieces or bearings, with three of the sides converging at a predetermined angle. The wood P is then fitted and slid into this inverted-V shaped space and fastened therein by the bevel-piece P, adapted to close the end and form the fourth side to the rectangular space. With this construction of parts any other suitable material can be used, and when worn out can be very readily replaced without destroying or in any manner efi'ecliug portions adapted to hold the same in place. I

The under side of the upright t is hollowed out, as shown at t and is provided internally with a projecting lip, 2' on which the split end of the arm Q, carrying the roller B, rests, while the opposite end of this arm Q is pivoted to theund'er side of the carriage. As the hollowed-out portion of the upright is larger than the free end of the arm Q,resting therein, it follows that the free end will have a lateral movement; but this movement is controlled by the screw j, which passes through the side ot'the upright and bears against the arm, and moves it inward until the horizontal roller bears firmly against the trackway, where it is held firmly, and prevents the carriage from f wabbling and producing irregular coursinglines.

In all shingle-machines two-thirds of the entire friction is due to the resistance of the wood to the saw, and the remaining friction is due to the weight of the carriage and bolt. To

understand this, imagine a thirty-eight inch saw makingacontinuous cut ofeighteen inches at the rate ot'one-halt' an inch to the revolution, and you willhave a fair idea of the power required to overcome the resistance of the tim-.

her to being fed forward and of the side draft from motion of the saw. Heretofore, ordinarily, all the friction from the sawing is taken up by theflat gibs on the right-hand side of the machine; but my improved roller on the side of the slide-bearing before described reduces this friction to a minimum.

Some of the machines heretofore used are provided with a V-shaped track having a. wheel with an inverted-V-shaped periphery running thereon. This construction takes the net weight of the carriage and bolt advantageously, but meets the side thrust of the saw at a disadvantage, because tl'ietendency is to force the wheel to climb the side of the track,

which produces friction. Another and serious defect to the use of the inverted-V-shaped wheel is tliat,while sawing, the airis tilled with a dust composed of pitch, grit, and woody fiber. Thisgets on the track,and the inverted- V-shape'd roller runs over it and compresses it into a lump, which is increased every time the roller runs over it, which consequently raises the carriage higher and higher, and makes a ridge in the shingle,which seriously impairs its market value. Again, in order to provide bearings for the inverted-V shaped rollers the carriage has to be constructed very heavy'and deep,w hich increases its cost, and also increases the labor of starting and stopping. If sawdust should become impacted between my horizontal rollers and the trackway, it would draw the carriage sidewise in the same horizontal plane, and cannot thereby make any imperfection'in the shingle.

The remaining portion of my invention relates to an improvement for firmly holding the machine on the floor or foundation, while at the same time it-canbe used to tighten the belt when the latter becomes loose. To accomplish this I secure the two J-shaped pieces S to the foundation by the horizontal arms 0, while the vertical arms are provided with openings for the passage of the main braces T, which connect the legs or ends of the machine and hold them firmly in position. The main bracesT-are bent, as shown in the drawings, and are provided on their horizontal portion with screw-threads, on which the nnts U and U are placed for holding the front standard firm, and on which the nut b is also placed. the latter being adapted to bear against the piece S, and I -slides m and be held in position thereby.

My improved marker is aplicable to any ordinary style of shingle-machine for scoring or marking the coursing line or lines on each individual shingle at the time of manufacture; so that no time is lost in chalk-lining the courses, while at the same time it materially increases the market value of the single without increasing the cost ot the machine or decreasing its capacity. It also avoids the necessity of using separate devices for accomplishiug the same result, and consequently dispenses with the extra labor necessary to work the separate machines.

My improved machine is susceptible of many changes for accomplishing the same result, so I would have it understood that I do not limit myself to any particular form or construction of parts shown, but consider myself at liberty to make such changes as come within the spirit and scope of my invention.

I do not claim in this application the construction and arrangement of inking devices shown and described, but reserve to myself the right to tile a separate application for Letters Patent therefor.
