CORPORATION OF MASSACHUSETTS PATENT OFFICE v APPARATUS FOR ASSEMBLIIVG BOOFIN G Application filed May 4,
This invention relates to apparatus for as- 1 sembling elements of substantially uniform thickness. from separate stacks or piles thereof, and finds one particular adaptation in the roofing'industry for assembling shingle elements of diflerent colors r designs into piles or bundles composed of a number of shingles of eachof the several colors or desi s.
Avery considerable proportion 0 prepared roofing shingles manufactured atthe present time are surfaced with mineral grit or the like, in various so-called multi-eolor effects. In the more desirable types of prepared roofing of this character, the aim is to produce a roof in which shingle portions of various colors are distributed haphazardly on the roof insuch a way as to avoid the possibility of any definite mathematical patterns or repetition of color effects. This is generally achieved in practise by manufacturing the" shingles or shingle strips in separate runs, the color arrangement of the shingles or strips of one; run differing more or less from those of the other runs, and subsequently assembling the shingles from the separate runs, preferably according to some preconceived plan, into packages. in which there will be a number of shingles fromeach-run. In practise also, the arrangement or sequence of the shingles in some of the bundles differs from that in the others, so that when the shingles are taken successively from'a number of such bundles and applied on the roof, the desired ornamental appearance will be secured.
' Hitherto it has been the practise to store a considerable quantity of shingles from each of a number of runs and then by manual labor, assemble the shingles from the several runs into bundles containing shingles from the several runsarranged therein as described. Somewhat the same general procedure is practised in conjunction with shingle strips differing from one another in tab-configuration, produced inseparate runs but used in combination with one another as a set in laying the roof.
It is an object of my invention to provide mechanism whereby shingles or shingle strips differing from one another in the color arrangement thereon, or in the tab design there- 1929. Serial o; 360,549.-
of, may be assembled into bundles containing the various shingles or shingle strips in definite sequence, the mechanism being also operable to vary the sequence in different bundles.
In accordance with the invention, I provide adjustableshelves or brackets each of which is adapted to hold a pile or stack of shingles or shingle strips from one of several runs in proper relation to means co0perating with the several stacks of shingles for successively withdrawing therefrom one of the also made for continuing or repeating the aforesaid assemblage until a bundle of the desired number of shingle elements is formed. Accordingto the preferred form of the invention, each of the stacks of shingles which are to make up the set or series in the bundle is supported in such a way that the lowermost shingle in thestack may be readily withdrawn therefrom, and the arrangement of the whole is such that the. withdrawal means operates upon the several stacks to withdraw the lowermost shingles thereof in succession and deposit them in a suitable receptacle or onto a collecting device. I
The invention will be more clearly understood from the, more .detailed description which follows, and from, the accompanying drawings in which,
Figurel is a side'elevation of the preferred embodiment of the invention,
Figure 2 is a plan view thereof,
Figure 3 is a detail in perspective of partof the mechanism, I
Figure 4 is a detail in section showing the action of the withdrawal meansupon astack of shingles, and
Figure 5 is a fragmentary view, partially in section, showinga modified construction of the supporting means for the stacks of shingles. g
Referring more in detail to the drawings, the numeral 10 indicates a suitable framework for the mechanism and the numeral 11 denotes a series of spaced, endless chains pass-- ing around the sprockets 12, suitably Journaled in the framework and driven from any convenient source of power, as by means of a pulley 12a.
spaced fingers or pins 13, the fingers on the several chains being in transverse alignment and functioning as the withdrawal means for the shingles from the several stacks in a manner as presently will appear.
In order to support a numberof stacks of shingles or similar elements in operative relation to the mechanism thus far described,1 provide a series of spaced supporting members comprising brackets or shelves 15 secured to one of the members 10a of the supporting structure 10 and constructed of angular sections each having an upright 15a and a bedplate 156 extending substantially at right angles therefrom, the several sections oi each bracket being spaced from each other as at 15c and'the several shelves being spaced from each other. If desired, the uprights 15a of each bracket may be in one piece, with the portion 15?) formed as a recessed plate. Each bracket 15 of the series is arranged for adjustment relative to the chains 11, as for example, by'means of extensions 16 secured rearwardly of the uprights 15a, and slotted as at 17 to accommodate securing bolts 18 passing therethrough and through the supporting member 10a. The spaces 15a intervening between the sections of each supporting member 15 are in the same general plane with the chains 11 so as to accommodate the pins or fingers 13 for free passage therethrough In practise, the supports-15 will be adjusted to a position in which the bed-plates 15bthereof are spaced from the chains 11 a distance slightly in excess of the aggregate thickness of the total number of shingles or other elements to be collected in one pass of the chains beneath the brackets, and the pins or fingers 13 will be of a height sufiicient .to extend substantially to the upper face of the lowermost element in each stack, but insulficient to extend therebeyond. As will be noted from Figure 1, the stacks of elements are arranged on the sup,- porting shelves with the plane of the elements in parallelism, to the plane of travel of the chains and with the edges of the elements extending in planes generally at right angles to the plane of travel of the chains. Hence, the shingles in each stack will lie in planes at an angle somewhat greater than 45 to the horizontal so that the weight of the stack will bear largely upon the'portions 15a of the supporting shelves rather than upon the bedplates 150, thus offering comparatively little resistance to the progressive removal of the lowermost shingle in each stack by the pins In order to preclude the possibility of the shingles in the stacks tilting or falling backwardly, when arranged in the position illuszitrated, stop plates 20 may be adjustably secured to the supports 15.
Mounted adj acent the discharge or delivery 1 shingle strips from six separate runs, the
shingles from the several runs designated as A, B, C, D, E, F, and illustrated by squarebutt strip shingles, may be stacked upon the several shelves in the order named. It will be understood, of course, that the shingles of each, of said runs differ in color, or tabdesign, orboth, from those of theother runs. During the forward movement of the chains, the transversely aligned fingers 13 carried thereby will grasp the bottom-most shingle in each stack along its rearward edge as clearly "shown" in Figure 4, and force the same from beneath the remainder of the shingles in the stack, whereupon the shingle will drop onto the chain and move forwardly until the fingers 13 come into contact with the lowermost shingle of the succeeding" stack and withdraw the same therefrom.. Each set of fingers 13 thus withdraws the bottom-most shingle of the several stacks in succession so that by the time the shingle first withdrawn passes beyond the last stack in the series it will have superposed thereon, in definite order, one shingle from each of the other stacks. As the-complete set reaches the discharge end of the chains, the several shingles thereof will pass over the inclined plate 24 and into the collectin device 23. The operation continues as described, the succeeding series of pins 13 withdrawing the then bottom-most shingle of the several stacks and when a sufficient number of such sets of shingles are accumulated to form a bundle, they may be removed from the collector23 as by sliding the bundle laterally over the idle rollers 22. v
then be bound or wrapped and the bundle may in any suitable fashion.
rality of sets of'shingles from the several stacksarranged in the bundles in recurring series. In order, however, to avoid objec As will be apparent from the above, the bundles thus collected will contain a plu-- number of bundles have been accumulated in which the sequence of the shingles therein is A, B, C, D, E, F, the stacks of shingles from said runs may be arranged on the supporting shelves in the order 1%, C, B, F, E, D; so that the bundles assembled during the operation of the machine as described, will have the shingles arranged therein in the lastnamed order. This variation of the sequence 'ofthe shingles in the completed bundles may obviously be carried'to as many permutations as the number of diiferent shingles will permit. While I have illustrated the operation of the machine in conjunction with six stacks of shingles, it is obvious that a greater 1 or lesser number may be used. Where the number of shelves are in excess of the number of different typesof shingles to be assembled, such shelves as may be unnecessary, may be simply left idle without altering the.operation of the machine.
In Figure 5, I have shown a modified construction 'of the supporting shelves 15, wherein instead of the flatbed-plates 150, I use a series of sectional idle rolls 30 journaled in the side members 31 spaced from each other to accommodate the pins or-fingers 13. By means of these idle rolls, the withdrawal of the bottom-most shingle or other element of each stack may be facilitated.
Although I preferv a construction such as illustrated, wherein the stacks of shingles are supported at an angle to the horizontal, it would be quite feasible to mount the chains for travel in a horizontal path, and employ the withdrawing mechanism described in conjunction with stacks positioned so that the shingles therein also lie in horizontal planes. With such construction, a suitable vertically disposed retaining plate would be formed with the supports adjacent the forward ends thereof, with its lower extremity spaced from the bedlates 150, a distance corresponding substantially to the thickness of a single element or roofing strip, whereby the lowermost shingle of each stack may beejected therefrom without ejecting others in the stack.
Having thus described my invention, it will be understood that numerous changes and modifications may be made therein without departing from the spirit of the invention as defined in the subjoined claims.
