R. THYER PREFABRICATED HOUSES 2 Sheets-Sheet 2 Filed Aug. 17, 1954 INVENTOR.

ROGER THYER ATTORNEYS PREFABRICATED HOUSES f Roger Thyer, Piqua, Ohio, assignor to Inland Homes Corporation, Piqua, Ohio, a corporation of Ohio 'Ihisl invention relates to prefabricated houses. More particularly the invention has-relation to the prefabrication of wall sections for prefabricated houses, and it is especially concerned with the exterior finishing of such wall sections. l

, As is well known, shingles are an excellent exterior v linishingmaterial for use on a house, from the several standpoints of general appearance, performance, and especially initial cost as compared with other preferred materials such, for example, as lap siding. However, the use of shingles offers one disadvantage in the labor required for their application. The handling of individual Shingles necessarily consumes a corresponding amount of time and labor, and specic provision must also be made for maintaining all shingles in each row in the proper horizontal alignment. In addition, since shingles are of random widths, it is virtually always necessary to saw by hand a single shingle of the proper width to complete each row, inorder to fill the space between the next to last shingle and ythe corner board, window or door frame or'other'part which terminates the row, and this is an especially costly operation in terms of both time and labor.V

.This difliculty involved in the exterior iinishing' 'of 11.01186 walls is especially important in prefabricating oper ations. Thus if the shingling is clonel at` the building site, it normally requires the services of skilledcarpenters at correspondingly high labor rates, and even a skilled carpeuter can not too greatly speed up the application of individual shingles, especially on an already erected wall. The application of individual shingles at the factory while the wall sections are horizontal requires somewhat less physical effort, but it is still time consuming. In fact, this tends to be a major bottleneck in prefabricating operations in that shingling ordinarily requires comparatively so much more time than any other step of prefabrication that it tends to retard all of the other steps and thus the production of the factory as a whole. j

v I tis'accordingly a primary object of the present invent ion"to provide an improved method of prefabricating wall sections for a house which utilizes shingles as the exterior finish for the walls and especially` which enables the shingles to be applied to each wall section at the factory with such ease and speed as to establish a time foi-"the shingling operation'suiiiciently comparable with the time required for the other prefabricating steps tomake possible an overall reduction in the production timefor eachA wallsection andvthus 4to increase'the production rate of thev factory as a whole.

additional object of the invention 1s to-provide such a'method which will facilitate the joining of the shingled areasof adjacent wall sections and gables during erection of'jthe'house at the building site and which will thus-reduce-both the time and laborrequired for completion of` thednouse.

furtherobject of the"inve'ritioxfi` is to provide a method".

rf'shin'gli'ngv a' prefabricated` wall "section 'wherein the shingles are first preassembled and connected in elongated 1min-States Patented June 30, 1959 ICC rows or pallets including both an inner or under course `and an outer course of shingles together with a substantially continuous wooden strip which acts as a connector for the several shingles enabling the production of a continuous row or pallet adapted to be cut to any desired length up to the length ot a wall section. Another object is to provide such a method wherein these individual shingle assemblies are then applied to the frame of the wall section by first nailing through the connecting strip to the studs ofthe frame, mounting successive assemblies with the under course shingles therein seated on the top edge of the connecting strip on the next lower assembly, and then fastening all of the outer course shingles to the connecting strip on the next lower assembly or row.

It is also an object of the present invention to provide shingle assemblies or pallets and shingled wall sections .produced as outlined above to accelerate the production and erection of prefabricated houses.

Further objects and advantages of the invention will be apparent from the following description, .the accompanying drawings and the appended claims.

In the drawings- Fig. l is a view in side elevaticn of a portion of a prefabricated house constructed in accordance with the in'- vention and with portions broken away to illustrate details of internal construction;

Fig. 2 is an enlarged fragment of Fig. 1;

Fig. 3 is a fragmentary section on the line 3--3 Fig. 2;

Fig. 4 is a further enlarged fragmentary section on the line 4-4 of Fig. 2;

Fig. 5 is a fragmentary section through the gabled end wall of the house shown in Fig. l and on a somewhat larger scale; Y

Fig. 6 is an extended, two-part view showing somewhat diagrammatically an arrangement of apparatus forming a production line for carrying out the method of assembly and connecting shingles in accordance with the. invention;

Fig. 7 is an enlarged fragmentary section taken on the line 7-7 of Fig. 6; and

Fig. 8 is a fragmentary perspective view lookinggenerally from left to right in Fig. 6.

Referring to the drawings, which illustrate preferred embodiments of the invention, the house shown fragmentarily in Figs. 1-5 includes a plurality of prefabricated wall sections 10 and a foundation 11 supporting a floor 12, and the house is provided with end gables 13 and trusses 14 cooperating with the roof 15. Each of the wall sections 10 is shown as comprising a bottom plate 20, a" top plate 21 and a plurality of vertical studs 22, these frame parts being formed of standard 2 x 4 lumber. Since it is not practical to handle a single wall section of greater length than 16 to 18 feet, two or more sections are nailed or bolted together to form the longer walls of the house, the joints between sections at the corners of the house being provided with corner members 24 such as boards or shingles. Frames 25 of conventional construction arel inserted inthe window or door` openings in each wall section 10.

The exterior linishing of each of the wall sections 10 is provided by multiple rows of double course shinglies,.an outer course of shingles 30 and an inner or under course of shingles 31. The butts of the outer course shingles overlie the butts of the under course shingles by a prede`4 termined distance as shown, and these outer course shingles are preferably of a finished and high grade, but since the under course shingles are wholly covered, they may be of an inferior grade. Between the shingles and other suitable insulating board nailed directly to the studs 2 2. Theprefabricating operations of ,the invention invclude substantially completeconstruction of these wall .sections 10.atthe factory in order to reduce to a minimum the requirements of labor and time at the building site. In accordance with the invention, the under and outer course .shingles in each'row are preassembledand connected -by .a substantially continuous wooden strip -35 of a lesser. width than the distance by which the outer course shingles overhang `the under 'course shingles, satisfactory .'results having been obtained with these strips 35 -formed .-by .conventional plaster laths. 'Thestrip 35 is.superim .posed on the outer course shingles 30 nearrbutspaced .below thetips thereof, and it is secured Ato both courses .ofshingles by small nails or equivalent rmeans such as .wirestitches or staples 36. As shown in Figs. 3 and -8, eachlong strip 35 is .composed .of aplurality of shorter Alength .sections of .ship lap construction as indicated at 3,7 to .provide .an .essentially continuous strip in each complete shingle r'assembly or..pallet.

Figs. ..6-8 illustrate .diagrammatically the method of .preassembling shingles in accordance with the invention n table 40 shown as tilted to a convenient working angle and having supporting legs 41. Along the front edge. of the-Work table is a guide member 42 which has a -generally Z-shaped configuration providing offset guide strips 44 and 45 for receiving the butt ends of the shingles 30 and 31 respectively, and the Zzshapeof this guidemember minimizes frictional contact thereof with the shingles as shown in Fig. 7. In addition, Athe under course shingles 31 are shown as riding on a conveyor belt 46 which may be provided with a suitable drive motor .(not shown) and which is arranged at a downward angle inthe direction of travel of the Vshingles along the work table in order to impart a biasing force tending to urge the shingles into the properly maintained guided contact with the guide strips 4,4 and 45. Preferablythe .belt 46 will travel continuously at a faster rate than the yshingles to maintain a continuous frictional drive on the shingles while permitting diem to slip with respect t0 .the belt.

In practicing the method of the invention on this work table, .the under and outer course shingles are superimposed Iby hand at the assembling station formed by the left hand end of the table as viewed in Fig. 6, with proper care being taken to have the junction between each adjacent pair of under course shingles 31 .covered by an outer oourse shingle 30. The assembled but still unconnected shingles then pass under a guiding and holding rnernber 50 shown as a metal strap supported by overhanging brackets 51 and having its left hand end turned up at 52 to guide the successive shingles thereunder. Downward pressure on the advancing shingles is also maintained by an idler roller 55 mounted by shaft 56 on brackets 7 to overlie the advancing outer course shingles, and this roller may be duplicated and provided witha belt similar to the .belt 46 ifdesired.

The successive laths which form the connecting strip 35 are superimposed on the advancing shingles as they approach the securing station represented by the electrially operated stitcher indicated generally at 60, and the guide member 5t) .serves also as a guide for the placing of lthese laths. The securing operation is preferably per formed at relatively close intervals in order to assure that the vparts are all properly secured together, satisfactory results having been obtained with staples or stitches applied at intervals o f the order of two inches, and the end srof thesestaples or stitches are preferably clinched',h asindicated .in Fig. 4, as by having asuitably hard surface o r'backqup plate on table 40 at the securing station. For automatic operation of the stitcher 60, a control switch 61 may be mounted on the work table adjacent the path of the shingles for actuation by a cam wheel 62 riding on the lath strips 35 and designed to actuate the switch 6% .periodically 'at the desired frequency as eiipvlxained a Q'f.

- The assembied .and `contracted .shingles Aadvancebeyond the securing station until they reach the desired length. Accordingly, the work table is desirably equipped with an adjustable stop 65 spaced beyond a severing station represented by a hand operated power saw 66. The stop 65 is mounted for adjustment lengthwise of -the table to the proper fixed distance beyond the saw 66, as indicated at 67. The saw is in tnrn ,mounted on a frame 68 and operates in a slot 69 in the 'table top. Thus when the assembled shinglepalletreaches the desired length established bysontact with ,the stoms, it .is lmerely-.r1e, .2,nvv

Vt "interrupt the' feedlons .eDQush t9 'Operate ,theaw 66 to cut otf the portion of the shingles between the saw and `the stop, after which theassemblingoperation proceeds following removal of the cut length from the table.

Fig. 6 also shows a saw 70 mounted between the stitcher 60 and saw 66 and operating lengthwise of the table on a stand 71 in cooperation with a slot 72 in the table top. This sawis used optionally to trim the tips of the assembled shingles extending beyond the strip 3 5,

the resulting trimmed shingle palletsy being utilized special locations on the wall section as described below. For general use, however, the tips of the singlepallets remain untrimmed as shown in Fig. 5.

The shingle pallets assembled as described in connection with Figs. 6-8 are applied tothe wall sections in the manner illustrated in Figs. 1 5. The several rows of shingles -are Vapplied successively one above the other by first nailing the strip 35 of each pallet to each of the studs 2 2 as indicated at 75, and the butts of the under course shingles of each successive row are then seated on top of the strip 35 of thc nextlower row. Allouter course shingles are then finally secured in place means ofv nails 7-7 positioned to secure the butt end of each shingle 30 directly to the strip 35 on the next lower row, thus establishing a strong construction since each nail V77 traverses notonly the thick portion of as hingle 30 and the strip 35 but also the tips of the next `lower inner and outer course shingles as Well as thesheathing 33 as shown in Fig. 4. It will be apparent that equivalentv fastening means 'such as staples or stitches can be in place ofand as equivalentto the nail 77. i

`Since the shingles in each pallet assembled as de -Y scribed in connection with Figs. 6-8 are held together only `by the supporting strip 35 of the pallet, which may extend to a length as great as the `16 to 18 foot widthlof a single wall section, the individual pallets are quite limber and may require relatively careful handling, .esp e cially inthe longer lengths. This is not disadvantageoun however, since in factory prefabricating operations, the shingling is most conveniently done with the wall sections lying horizontally so there are no particular stresses there'-rv on while the pallet is being nailed in place. It is there.-A fore unnecessary to nail or otherwise to secure the butts of the shingles together prior to application to the Wall section, thu/s further saving in tirne and materials.

The method of the invention results in the production of shingle pallets in which both the under and outer courses of shingles have their side edges in flush coplanar relation at both ends of the row, and the length of each pallet may be accurately predetermined by the setting of the stop 65. It is therefore possible to forni such *pallets in proper'lengths Yto rit preis'ely between the c ornerinent: bers 24 andfdgr 0r.

These gaps are laced in' 'during erection of the house by means of individually applied shingles, but vsince this representsV sa' relatively small proportion of the total shingling operation and would in -any case be required for conventional shingle application, it does not appreciably detractfrom the advantages of the invention as outlined above:`'Fig.--l also show a strip of'building paper 78 covering the junction betweenthe end studs on adlaenttwall s.cti.0ns` to rassure a. weather-tight joint.

The precise manner of application of the bottom row of shingles depends upon whether the house is built with a oor as shown at 12 in Fig. 5 or on a concrete slab in place of the foundation 11. For a house to be erected with a oor, the bottom row of shingles is advantageously applied at the building site in the form of special pallets constructed as shown in Fig. with a spacer strip 80 nailed to the back of the buts of the outer course shingles, and the next to bottom row of shingles is left unnailed along its `lower edge at the factory to pro- .vide for proper application of the bottom row at the site as shown. The lower edge of the lowermost pallets is nailed directly through the strip 80 into the sill 81 to cover the oor and the joists 82. For houses to be built on a slab, the bottom row of shingles may be applied at the factory with the spacer 80 being nailed directly into the bottom plate 20.

Fig. 5 also shows the manner of finishing the junction between the top of a wall section and the end gable 13. The top row of shingles on the wall section has its tips trimmed as indicated at 85 and :as described in connection with the saw 70 in Fig. 6. The gable is shingled with preassembled shingles in essentially the same manner as the wall sections, with the bottom row being applied in such position as to overhang and lit with the top row on the wall section as shown in Fig. 5. A similar row of trimmed shingles can be used along the top of the side Wall sections and then nished by a top facing board 88, preferably after removing the strip 35 therefrom, or the top shingle row can be separately applied in the form of individual shingles.

It will therefore be apparent that the invention greatly facilitates the use of shingles in the prefabrication of houses by reducing both the time and the labor required for shingling operations. Since the shingles are automatically properly aligned during preassembly and connection with the strips 35, correctly aligned placement of all rows on the wall is readily obtained. In addition, both the :assembling and the application of the shingle pallets are so simple that both operations can be performed by relatively unskilled help, correspondingly reducing the labor cost, and these advantages are further enhanced by the reduction in the time and labor required for erection of the house due to the greater amount of work which can be done at the factory as a result of the invention. At the same time, the entire operation including the prcassembly and the application of the pallets is so greatly accelerated as compared with the use of individual shingles that the wall sections can be shingled at substantially the same rate required for initial assembly of each section frame, thus assuring steady operation of the complete factory production line and resulting in reduced overall cost of the inished house.

The invention is also important as providing a properly insulated and weatherproof wall section at minimum cost, and especially as making practical the use of highly economical sheathing and exterior finishing materials on the same wall. Thus while the shingle pallets of the invention can be utilized in conjunction with wooden sheathing, entirely satisfactory results may be obtained with the use of sheathing of the asphalt-impregnated pressed liber type which could not as a practical matter be utilized with conventional individually applied shingles because it is too soft to hold nails with adequate firmness. With the present invention, however, the reinforcing strips of; the shingle-,pallets provide both for securing these pallets directly to the studding and alsofor securing the individual shingles together and tothe wall as a .whole even when such relatively soft sheathing is used; At the same time, the use -of anaSphaltimpregnated' sheathg ing eliminates the conventionally required building paper over theentire wall which should otherwise be used for proper sealing, with resulting .further economy of production and materials.

.While the. methodsand. products .hereinldescifibd constitute preferred embodiments of the invention, it is to be understood that the invention is not limited to these precise mehods and products, and that changes may be made therein without departing from the scope of the invention which is delined in the appended claims.
