To all whom it may concern:
Be it known that I, ALEXANDER S. SPEER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented anlmprovement in Methods of Making Roofing Slabs, of which the following is a specification;
My invention relates .to an economic 1 method of making shingle units, or striff designed when laid in a roof to simulate a plurality of individual shingles.
The invention aims to provide from a sheet of roofing material of well known, or improved, construction which is of much greater length than width a plurality of shingle units, orstrips, with a minimum of waste, and each unit of such form that when used to construct a roof in the usual way the end edges of the unit will register with the intact portion of all of the overlying units, or strips, and will not register with the cutout portion thereof, or spaces between the projections which simulate individual shingles.
The invention is illustrated in the accompanying drawings, in which;
Figure 1 is a plan view of a sheet of roofing material with the lines of cutting for one form of shingle unit illustrated by dotted lines.
Fig. 2 is a plan view of a section of a roofing formed by the shingle units pro duced in the manner illustrated in Fig. i.
Fig. 3 is a view similar to Fig. 1, showing in dotted lines the lines of severance for producing a different form of shingle unit, and,
Fig. 4 is a section of a roof formed by shingle units of the character produced in the manner indicated in Fig. 3.
Figs. 5, 6 and 7 illustrate that the method can be carried out in connection with a strip of a width onlysufiicient to cut one slab crosswise thereof.
A strip of roofing material of well known, or improved construction, and of materially greater length than width is designated 1 in Figs. 1 and 2. From a strip of this char? actor a plurality of shingle units, as will be hereinafter described, are produced. The
shingle unit, or strip, is designated 2 in in each instance it includes a front portion comprising a plurality of projections, or tongues, 2, 3 the projections 2' being of semi-hexagonal shape, with intervening spaces which may be, as shown in Fig. 2,
the same size and shape as the tongues, or
courses so super-imposed that the projections, or tongues, of each course will be exposed in advance of the tongues, or projections, of the overlying course and with the middle of the spaces between the tongues or projections. of the immediate underlying course in register with the middle of the tongues or projections of the immediate overlying course.
As the body portion of each unit is preferably "twice as wide as the width of the ton ues throughout the major portion of a roo made up of these units, each course has two courses superimposed thereupon, as shown in Figs. 2 and 4.
In prior practice shingle units have been made and have been used in constructing.
roofs substantially in the manner described and it has been the uniform practice in these articles of the prior art to have the end edges of the body portion of the units disposed substantially perpendicular to the general line of the front edge of the blank, or perpendicular to the line of each horizontal course of blanks as laid in a roof, with the result that portions of the abutting ends of continuous units will register with the spaces between the projections of certain of the overlyingunits.
For instance, were the end edges of the units, shown in Fig. 1, arranged perpendicular to the general line of the front edge of the unit, or perpendicular to the lines of the courses, portions of the abutting edges of the body portions of the blanks of the lowermost course would be in register with the spaces between the projections of the blanks forming the third course.
My invention aims to insure the covering 1 of the lines of juncture between abutting units by the intact portions of the units or ing the described characteristic from a strip of roofing, such as that designated 1, and with a minimum of waste, I cut the units from the strip with the width of the units disposed substantially lengthwise of the strip, the length of the units being disposed substantially widthwise of the strip. The
'units are preferably made of such lengththat a pair of the same will correspond to the width of the strip 1 and the general line of severance forming the front and back of each unit extended other than at right angles or bias to the lengthwise edge of the strip. As shown in Fig. 1, the gen-- eral line f severance is at such an angle that the edges on one side of the projections 2 are parallel with the lengthwise edges of the strip.
Thus, each lengthwise section of the strip 1 of a width corresponding to the maximum width of the shingle unit is designed to form a blank which, when severed through the middle, will provide two shingle units and this line of severance is along a line parallel to the side edges of the strip 1.
i As shown in Fig. 1, the outer or end edges of the bodyportions' of the units .will be formed by the lengthwise edges of the strip 1 and due to the angle of the general line of severanceforming the lengthwise edges of the blank the end edges thereof "formed by the lengthwise edges of the strip 1, as
well as the edges formed by severing the blank through the middle, will be disposed at the desired angle to the general line of the lengthwise edges of the blanks.
In the exemplification of the invention shown in Fig. 3 the same general plan for severing the units from the strip 1 is followed, but there isslightly more waste than in the plan illustrated in Fig. 1', due to the difference in the shape of the projections, or tongues, provided on the units.
Figs. 5, 6 and 7 show a strip narrower than that of Figs. 1 and 3 to provide mate rial across its width for only one slab. In Fig. 5, the outer edge of the extreme rojec- .tion 2 coincides with one of the e ges of the strip.
The present case is based on subject matter divided out from application filed by me- April 7, 1919, #288,035.
It will be seen that the method is so performed that a shoulder is left at m which will provide for the overlapping of the slab above it, and a nail which may be inserted adjacent this shoulder will be protected. In the form of the method as carried out according to Figs. 1 and 3, it will be noticed that the central longitudinal line of severance is staggered and the shouldered con-v struction results from this.
