16 Claims. 1

This invention is directed to improvements in a machine or apparatus for producing insulated shingles for use in the construction. and building industry.

There is a definite and pressing need for a combination shingle having insulation affixed thereto in such manner that the ordinary act of laying the shingles, either as a roofing or siding covering, carries with it the establishment of an underlying layer f insulation. As a consequence, the use of insulated shingles effects a pronounced economy, and it is an object of this invention to provide a machine or apparatus for producing insulated shingles on a mass production basis, thereby achieving further economy.

It is a further object of this invention to provide a production machine which operates rapidly and effectively to bring pre-cut slabs of an insulating material into proper relation with the shingles and to unite the same by the application of an adhesive material and with the aid of a moderate degree of pressing.

It is another object of the present invention to provide an insulated shingle production machine or apparatus which embodies improved means for processing the several parts of the final article in a simple and effective series of operations, thereby effecting a considerable saving in labor and cost of manufacture.

It is another object hereof to provide a production machine having improved features of construction and operation, as will hereinafter be more fully described.

` These and additional objects and advantages will be more specifically pointed out in the course of the detailed description relating to a presently preferred embodiment of the invention, as the same is disclosed in the accompanying drawing, wherein:

Fig. 1Q is a fragmentary view similar to Fig. 6 showing the regulating means.

Reference will now be made to Figs. l, 2 and 3 for an understanding of the present machine. The frame structure of the machine comprises vertical members arranged in spaced pairs at each of the corners, so that the front pairs of members Il) andthe rear pairs of members Il are oppositely aligned transversely of the machine. These members are connected by suitable upper and lower transverse angle members I2 at the front and similarly located members I3 at the rear. The frame also includ-es a pair of longitudinally directed, side angle members I6 which are transversely spaced and secured to the l respective vertical pairs of members IIJ and II in position to project forwardly of the front members I0. A channel member I5 is carried on the upper surface of the inturned angle leg of each of the members I4, Iand a plate I6 spans the width of the machine to rest upon these channels and provide a platform upon which a stack of the shingles S (Fig. 9) may be placed. At the rear margin of the plate I6, a vertical support means I1 is arranged to support the front margin of a platform I8 which extends toward the front ones 0f the vertical members I0 so that its rear margin is open therebetween. The rear Zone of platform I8 is rigidly supported upon laterally spaced posts I9 secured thereto and resting upon the rear zone of the platform I6. Additional intermediate supports are provided, and are constituted by the enlarged cylindrical columns 20 arranged in a preferred spac-ed order as will appear hereinafter.

A rectangularly shaped, enlarged reservoir or open top tank 2l (Figs. 1, 2 and 8) is supported along its opposite longitudinal bottom margins by the inturned iiange legs of th-e elongate members I4. The front and rear transverse bottom margins of this tank rest upon the respective cross-angle members I2 and I3 (Fig. 1), so that f the tank is firmly and fully supported about its bottom margins and rests in a substantially horizontal position within the frame structure. This tank 2| is adapted to contain a supply of a suitable adhesive material, usually kept at about the level shown at A in Fig. 8. A suitable adhesive material is asphalt, and in order that it may be held in a desired iiuid condition, the tank is equipped with electrical heater strips 22 disposed along its bottom surface. Ihe tank 2| is shown for simplicity as having thickened walls for aiding in the retention of heat, but ya doublewall tank with insulation between the walls will serve as an equivalent thereof.

The open top of the asphalt reservoir or tank 2| is adapted to be closed by a conveyor platform of sectional construction, such that the loading of the tank may be accomplished by removal of one section without disturbing other sections. This platform serves as a tank cover to protect the asphalt and as a surface for supporting the insulation slabs I (Fig. 9) during their conveyance through the machine. In Figs. -2 and 8, the conveyor platform cover over the tank is comprised of a solid plate member 23 having a clear upper surface, an adjacent and removable intermediate plate member 24 having a continuous surface upon which a series of guide rail sections 25 are secured, and a third plate member 25 having a continuous rear surface portion adjacent the member 24 and a forward portion suitably cut-away or longitudinally notched to form laterally spaced plate extensions 2`| of relatively narrow extent and a pair of intermediate and spaced plate extensions 28 of relatively wider extent than the outer extension 21. This third member 26 carries a series of guide rail sections 23, each of which is arranged in longitudinal extension of and abutment with corresponding rail sections 25 on the intermediate member 24. It can be seen in Fig. 2 that the plate member 23 overhangs the rear transverse wall of the tank 2| to provide a suitable entrance lip 33 for the conveyor mechanism, later to be described. The

several rail sections 25 on plate member 24' are arranged in matched pairs identied by the oppositely directed beveled entrance faces 3|, thereby defining the entrance for each of three parallel guide-ways. The guide-way rail sections 23 carried by the notched plate member 26 are spaced from the notch margins so that a narrow lip surface 32 remains for effective marginal support of the insulation slabs I which are moved through the guide-ways. The end portions of plate extensions 21 and 28 overhang the front transverse wall of the tank 2| and are downwardly curved to act as exit lips for the conveyor mechanism. The rail sections 29 carried by these plate extensions are similarly curved for a like purpose, as may be better seen in Figs. 4 and 5.

The conveyor mechanism associated with the above described conveyor platform and guide rail assembly is comprised of a pair of laterally spaced and parallel endless chain belts 33, these belts 33 have a plurality of flights attached thereto, and each of these flights consists of av carrier or push bar element 34 spanning the belts 33. The conveyor belts 33 have a working span or pass across the tank 2|, as defined by the vertically adjustable sprockets 35 carried on a common shaft 35, the shaft 35 being mounted in suitable bearing blocks 3l adjustably carried by and between the vertical members (Fig. 2). The opposite end or exit of this conveyor pass is defined by the fixed sprockets 38 mounted on a commonshaft 39 bearinged in fixed blocks 40 carried by and between the vertical members I0. The sprockets 38 are preferably fixed in position so that they maintain the desired path of travel of the ight bar elements 34 over the curved lip of the plate extensions 2l and 29, see Figs. 4 and 5.

The conveyor mechanism has a pair of idler sprockets 4| (one only being shown in Fig. 1) carried on a common shaft 42, the shaft being supported in adjustable bearing blocks 43 carried by the vertical members l as shown. The drive for the conveyor comprises sprockets M mounted on a common shaft l5 (Figs. 1 and 3) This drive shaft i5 is disposed in xed bearing blocks 46 carried by the vertical members l5, and one end of the shaft is extended at 4l to mount an enlarged sprocket Q8 at the outer side of the frame. The sprocket @i8 is chain connected with a power output sprocket 119 (Fig. 1) of a speed reduction gear unit 55. The reduction gear unit 50 is detachably connected with an electric motor 5|, as by the coupling 52. The reduction gear 53 and motor 5| are secured to a suitable platform 53 carried on the angle member 5i which serves to tie together the bottom portions of members I2 and the structural details of the machine.

The means for feeding pre-cut slabs I of the insulation material, of the character indicated in Fig. 9, includes a magazine assembly M (Figs. 1 and 2) which is bodily removably secured to bearing pads 55 positioned on top of the pairs of vertical members The attachment is effected (one side only being shown in Fig. 1) by a laterally projecting wing plate 56 resting on the pad 55 and xed to the side angle member 5T of the magazine M. A brace plate 58 is also used to strengthen the assembly. The magazine proper is formed of an outer casing sheet set vertically and bent to form an open bottom, rectangular container having opposite side walls 50, a back wall 6| and a front wall 52. As may be seen in Fig. 2, the front wall 62 is notched in its lower zone to provide three sight openings 53 for observance of the loaded condition of the same. The back wall 5| is also notched in its upper zone to provide three openings 6 by which a stack of insulation slabs I may be placed therein. The'interior of the magazine casing is suitably divided into three compartments by a plurality of partitions 65, so that each compartment in which insulation slabs are placed includes a back wall loading notch 64 and a front wall sight opening 33. The magazine assembly M is located above the top surface of the tank cover plate 23 a distance (Fig. 1) which is slightly greater than the thickness of the insulation slabs I, whereby the stack of slabs in each compartment rest upon the plate 23, with only the lowermost one of such slabs in position to be pushed oif the bottom of the stack. When this is done, the stack will fall by gravity to expose the next slab. It will also be observed that each compartment of the magazine M is aligned with one of the conveyor guide-ways (Fig. 2), whereby the insulation slabs are properly conditioned for movement thereto.

The conveyor flight bars or carrier elements 34 are adapted to pass between the bottom of the magazine M and the surface of plate 23 so that each carrier 36 engages three exposed insulation slabs at one time and pushes such slabs off the bottom of the stacks for entrance at beveled faces 3| to the guide-ways. Since the guide rails 25 and The electrical power supply for theV motor 5| and such controls as may be required or desired have not been shown, in order to simplify 29 lie above the plane of plates 24 and 26, there has been provided fixed cam means 66 (Figs. 1 and 2) at'each side of the tank2 the cam means acting to elevate the carrier elements 34 for subsequent sliding passage over the rails 25 and 29.

Means for applying a coating of the adhesive material to each of the insulation slabs, as the same are carried along the working pass of the conveyor by elements 34, includes spaced roller members 61 mounted on a common shaft 68 bearinged in the tank walls such that the rollers are partly immersed in the adhesive material andA carry a surface film thereof during rotation. Scraper means (not shown) may be fixed in the tank 2| to regulate the thickness of the film, and other means may be employed to clean the rollers as they reenter the body of adhesive, so that the working surface of each roller is kept in condition. These rollers 61 are disposed in the zone of the notches of the plate 26 (Fig. 2) and have their upper surface running slightly above the horizontal top plane of the plate 26 for positive contact with the insulation slabs. Each roller 61 presents an effective adhesive applying surface which is not as wide as the Width of the insulation slabs moved thereover by an amount found to be effective in preventing the spread of the adhesive to the conveyor or fixed plate members. Roller operation is effected by a drive sprocket 69 (Fig. 2) fixed on the extension 16 of the shaft 68, the sprocket 69 being chain driven from a sprocket 1| fixed to the extended end 12 of the conveyor sprocket shaft 39.

Means for continuously agitating the adhesive material in tank 2| comprises the shaft 13 carrying a plurality of paddle blades 1li (Figs. 1, 2 and 8) which effect a continuous transfer of the more fluid stratum of adhesive near the bottom of the tank toward the upper stratum. This is important to maintain a uniform fluid condition of the adhesive, especially when using asphalt which tends to harden or solidify rather rapidly. The shaft 13 has a sprocket 15 on its outer end and this sprocket is chain-connected with a sprocket 16 (Fig. 2) fixed on the roller shaft extension 10.

' In conjunction with the use of narrow rollers 61 to limit lateral spread of the adhesive, means is also provided for terminating the application of the adhesive at a point just prior to full or complete passage ofthe insulation slabs past the line of roller contact. The terminating means operates to elevate or lift each slab at the proper time, thus positively breaking contact with the roller. The preferred means comprises a rock shaft 11 spanning the width of tank 2| and 1ocated ahead of the rollers 61, as may be seen most clearly in Figs. 2, 6, 1 and 10. This rock shaft 11 carries a plurality of adjustable fingers 18 arranged in pairs at the opposite end faces of each roller 61. Thus, there are six such fingers 18, and each finger is movable upwardly in the space or gap formed between the roller end faces and the adjacent margins of the guide-way lip portions 32 (see Fig. 2). Each pair of fingers 18 acts to lift one of the insulation slabs, and for this purpose the free ends of the fingers have been adjusted to move in an arcuate path close to but at one side of the Vertical center line of the roller axis. The operation of the shaft 11 is made responsive to movement of the carrier elements 34 at a predetermined point in the approach thereof to the zone of the rollers 61. For this purpose, a pair of trigger elements 19 are pivoted at the outer side f the tank 2| (Figs. 2 and 10) 6. oni pivot pins 80. .'One end of these triggers nor-i mally project above the plane of the conveyor platform (Figs. 6 and 10) so as to lie in the path of the carrier element 34. The opposite ends of the triggers are relatively loosely pivotally connected by pins 8| with the crank arms 82 fixed to the opposite ends of the shaft 11. A specific showing of one such trigger assembly is shown in Figs. 6, 7 and 10, and reference Will now be made thereto. The trigger mechanism is so mounted that the combined weight of the fingers 18 acts to rotate the shaft 11 and crank arm 82 in a direction for holding the triggers 18 in cocked position of Fig. 6. Upon contact being established between the trigger 19 and carrier element 34, it can be appreciated that the trigger will be rotated downwardly about its pivot pin to move the crank arm 82 upwardly, causing rotation of shaft 11 in an opposite direction (clockwise), such as to raise the fingers 18 (Fig. 7) sufficiently to break contact between the rollers and the overlying insulation slabs. Thus, the application of adhesive material to the slabs is desirably terminated at a point just short of the trailing margin of the slabs. The trigger 19 is automatically restored to cocked position (Fig. 6) after the carrier element 34 has passed beyond it, thereby conditioning the same for operation by each succeeding carrier element.

Referring particularly to Figs. 1, 3, 4 and 5, it can be seen that the plane of the conveyor guide platform across the top of tank 2| is located above the plane of the shingle supporting platform I8, and the two levels are separated by a gap or space which permits the carrier element 34 to pass downwardly through the gap on its return or idle pass to the zone of the magazine M. A swingable or rockable mechanism has been provided adjacent this gap zone to effect the proper transfer of the insulation slabs I from the conveyor to position upon a shingle placed on the platform I8. The mechanism includes a rock shaft 83 carried in end bearings 84 upon bearing pads 85 at the upper ends of the vertical members I0. Near one end of the shaft, a timing lever or finger 86 has been positioned to project into the path of movement'of the carrier element 34. A second lever or finger 81, near the opposite end of the shaft 83, projects toward the path of travel of the carrier element 34, but this finger is somewhat shorter than timing finger 86 and is set at a different angular attitude. The intermediate span of rock shaft 83 carries three working fingers 88 all set at the same angular attitude and each being aligned with one of the conveyor guide-ways for the insulation slabs. The fingers 88 are at a different angular attitude relative to fingers 86 and 81, and from a comparison of the location of fingers 88 relative' to guides 98 in Fig. 3 with the relative longitudinal spaced alignment of the guides 99 with the several notches in plate 26 formed between the supporting lips or surfaces 32, as in Fig. 2, it will be appreciated that each finger 88 swings through the end zone of the aligned notch in plate member 26 beyond the adhesive coating rolls 61. Further inspection of Fig. 5 will reveal that lingers 88 pass below plate 26. The rock shaft 83 with its several finger elements is normally maintained in the full line shown of Fig. 4 by means of a counterweight 89 carried by the weight arm 9D, and the angular position is determined by the weight 88 resting on an angle memberul as a stop. Member 9| be further 'described presently in connection with Figs..1 and 3,.

In cooperation with thev above rockable mechanism, each bar element 34 is provided with an upstanding abutment element 92 xed at the proper end zone for travel into engagement with timing finger 86. The opposite end of each bar 34 carries an enlarged abutment element 93 positioned for engagement with the finger 81. Each bar element 34 is provided also with three spaced notches 94 which are aligned with the respective fingers 88,` and' these. notches are in the leading edge so that the fingers 88 may enter the same and assume positions of engagement behind the insulation slabs brought thereto by .the bar elements.

Observe that the full line position of the parts in Fig. 4 illustrates the normal attitude of the same at theV moment a bar or carrier element 34 has advanced so that the abutment element 92 attains contact with timing finger 86. As the conveyor travel continues, the element 92 rocks or swings the several lingers against the gravity load of counterweight 89 to the broken line position, such that the fingers v88 are brought into the notches 94 and begin to pick up the insulation slabs. Finger 81 and' abutment element 93 are not yet in engagement. At this point, the insulation slabs I have reached their transfer stage and the leading margins are now resting on thetab surfaces of the shingle S supported on platform I8.

The full line showing of Fig. 5 is still another position of advanced conveyor movement at .the point Where abutment element 93 attains engagement with the nger 81. Observe that the ngers 88 are now in full control over the insulation slabs I and have effected an advance thereof ahead of the carrier element 34. The broken line showing of Fig. 5, illustrates the final position of the transfer mechanism when the insulation4 slabs I have been fully transferred to the platform I8 and the abutment element 93 is beginning to ride downwardly and part engagement with nger 81. Subsequent travel of the conveyor moves the carrier element 34 through the gap betweenA the .tank 2| and rear margin of the platform I8. In Fig. 2, the platform margin issutably notched at 95 and 96 to permit unobstructed passage of thev respective abutment elements 92 and 93. As soon as element 93 and finger 81 break engagement, the counterweight 89 drops to the angle member 9| and automatically restores the mechanism for the next operation` in response to the carrier element 34 next in line.

The proper assembly of the three insulation slabs I upon each shingle S is regulated by means now to be described. In Figs. 2 and 3, it can be seen that the shingle platform |8` is provided with a centrally located and laterally spaced pair of alignment cam elements 91` which are adapted toguide the center one of the shingle tabs during the placement thereof upon the platform |8. Once this tab is received between these cam elements 91, the shingle is then pushed toward the rear margin of theV platform, and is brought to a proper inward position upon abutment of the opposite wing portions of the shingle with spaced stop blocks 98. At this time the three tabs of the shingle are located above the vertical columns 29 (Figs. 2 and 3). Each shingle tab now lies between and below a pair of laterally spaced guide'ns 99 being carried on support elements |00 fixed to the platform I8. The guide ns 99 are vertically directed and extend to: the rear margin of the platform I8 so that the adjacent pairs thereof act to guide the oncoming insulation slabs over the shingle tabs.

The next operation of the present machine is lto exert a compressive load on the insulation slabs so as firmly to unite the same with the shingle tabs and complete the assembly of the insulated shingle combination. The means provided to carry out the pressing operation includesl the transversely directed angle member 9| supported at its opposite ends upon the upper ends of the vertical extensions of posts I9. This member 9| carries spaced sleeve guides |0|, each located centrally of the pairs of guide ns 99. Each guide sleeve receives a vertically movable rod |02, at the lower projecting end of which is secured a platen or pressing plate |03, and the plate |93 moves between the adjacent guide ns 99. The upper end of each platen rod |92 is received in a sleeve socket element |94 xed to a common carriage member |95. The rod end portion received in the socket |04 carries a pin |96 which projects through a socket slot |01 to prevent angular displacement thereof. Each platen rod |92 is resiliently urged downwardly to the limit of movement of pin |06 in slot |01 by a spring |08 disposed between the fixed socket and a collar |99 on the rod. This yieldable connection of each rod |02 with the common carriage member |05 permits the several plates |93 to assume positions accommodated Ito the slight variations of insulation slab thickness which normally occurs.

The carriage member for the three press plates |03 is downwardly actuated from its normal raised position (Figs. 1 and 3) by a pair of draw rods |I9 secured to member |05 by suitable collar elements, and directed .to pass through apertures in platform I8 for similar connection with a transversely directed draw bar The draw bar I|| carries at its outer ends, angle bracket assemblies ||2 which are pivotally connected with respective levers ||3. The pivot connection of lever ||3 with the draw bar III is eiected intermediate the length of the lever, as may be seen in Fig. 1. Since there are two such levers II3, the single showing thereof in Fig. 1 may be taken. as typical for both. Lever |I3 is normally horizontally directed from a pivot connection at the lower end of a hanger member H4, the latter -being fixed upon a convenient portion of the angle member I4. The free end ||5 of the lever lies adjacent the hub zone of the sprocket 44 on drive shaft 45 and is directed to have contact with a tappet element ||6 iixed in the said sprocket hub. Thus, once in each full revolution of the shaft 45, the tappet element ||6 engages the end ||5 of lever ||3 and pivots the same about hanger I I4 until the lever and tappet eventually break contact. During this lever operation, the draw rods I I0 are downwardly displaced against the force of restoring springs II1, and this action serves to depress each of the platens or plates |03. This press operation is suitably timed to occur when the insulation slabs I have reached or are about to attain the intended position of final assembly with the shingle S.. The springs IIT act to restore the press mechanism to its normal position for subsequent operations.

From the foregoing description, it should be clear and obvious in what manner the present machine performs the several steps in the production of insulated shingles. The improvements reside in those individual and cooperative 9 means', parts, elements or sub-assemblies' which are necessary to the successful operation of the machine. It is expected that substitution of equivalent parts may be made herein Without departing from the scope of the claims hereafter appearing.
