Framing tool

Application filed March 8,

This invention relates to new and useful improvements in a framing tool.

One object of the invention is to provide a measuring device of the character described S whereby timbers may be measured, to be cut, at the desired angle, for use in buildings. A more particular object of the invention is to provide a scale, or measuring device, whereby rafters may be cut on the desired 10 bevel, and the , angle of the bevel may be readily varied for roofs of different pitches.

Another object of the invention is to provide a device of the character described whereby common rafters, and hip and valley 15 rafters may be readily measured to be cut at any bevel desired to give the roof the desired pitch.

With the above and other objects in view this invention has particular relation to cer20 tain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein:—

Figure 1 shows a side elevation of the device.

Figure 2 shows a side view taken at right angles to the view shown in Figure 1.

Figure 3 shows a cross sectional view taken 30 on the line 3—3 of Figure 1.

Figure 4 shows an end view of the device.

Figure 5 shows a side view of a rafter cut from measurements of the scale, and

Figure 6 shows a plan view of a roof 35 framework, shown for the purpose of better illustrating the use of the scale.

Ref erring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, ⁴⁰ the numeral 1 designates a flat measuring stick having a slot 2 extending approximately· from one end to the other thereof. There is an arcuate segment 3 fixed to one end of the base 4 and overturned from this ⁴⁸ base there is a flange 5 which lies adjacent the stick 1 and has the outstanding stud bolts 6, 6 which project through slot 2 and whose outer ends are threaded to receive the clamp puts 7, 7 by means of which said segment 3 ⁸⁰ is adjustably secured to the measuring stick , 1929. Serial No. 345,297.

1. There is a square having the arms 8, 9 at right angles to each other and. the latter of which has the aligned extension 9' formed with an oblong longitudinal slot 10 to receive the stud bolt 11 which projects out from one 55 end of the base 4 and is exteriorly threaded to receive the clamp nut 12 by means of which the square, above referred to, is adjustably secured to the base 4. The free end of the arm 8 overlies the front face of the segment 3 eo and has a lip 13 which engages under the segment 3 and thereby retains the arm 8 in association with said segment. The said face of said segment 3 has the scales 14, 15 for the common cuts and the hip and valley cuts 65 and the front face of the stick 1 has the scales 16 and 17 for the common cuts and hip and valley cuts, as hereinafter defined. The flange 5 has a pointer 18 attached thereto whose free end is upturned into association 70 with the scales 16, 17.

Secured to one end of the measuring stick I there are the arcuate segments 19,20 disposed at right angles to each other the front face of the former of which has the scales 21, 22 75 for common cuts and hip and valley cuts, and the front face of the latter of which has the scales 23, 24 for bevel cuts, all as hereinafter defined. Pivoted to the outer ends of the bases of these segments 19, 20 are the rules eo or straight edges 25, 26 whose free ends are retained in association with the scales of their respective_ segments by the lips 27, 28 respectively, which engage under the respective segments. The pivotal connections between the 85 rules 25, 26, and their respective segments are obtained by means of the respective stud bolts 29, 30 which project from said bases through bearing in said rules and whose outer ends are threaded to receive the clamp nuts 90 31,32. . ^r

In Figure 6 the common rafters are designated by the numeral 33, the hip rafters are designated by the numeral 34 and the valley rafters by the numeral 35. 96

After deciding the pitch to be given to the roof the pointer 18 should be moved to the number on the scale 16 designating the degree of rise or pitch of the roof previously decided upon and the edge of the arm 8 and 100 ,277 straight edge d of the rule 25 should now be brought to the corresponding figure of the scales 15 and 22 for the hip and. valley cuts and there secured. Before making this adjustment. however, of the. arm 8, the arm 9 <° should be moved longitudinally on the stud bolt 11, the long slot 10. permitting this, so as to properly form the plate notch defined by the edges c, c. In other words after ilie common rafters have been cut and while the arm *5 9 is positioned as shown in Figure 1 the adjustment is then macle for cutting the hip and valley rafters as above explained. When the arm 9, however, is swung around on the pin 11 the angle between the edges c, c will 80 describe an arc and will be carried out closer to the adjacent margin of the rafter so that the arm 9 must be adjusted back or downwardly as illustrated in Figure 1 so as to give the proper depth to the notch defined by the 85 edges c, c. This notch must be the same as the corresponding notch of the common rafters and the device is set to properly, form this notch when it is adjusted back in the slot 10 so as to give the depth of the common PO rafter notch. The valley rafters should then be measured off exactly as the common cuts were measured as hereinbefore explained, the number of measures necessary to give, the required length, being one half of the width 05 of the building in feet.

The designating numerals of each scale represent the rise, or pitch, in inches for each foot run of the building, that is, for each linear foot of the building taken on a hori- 100 zontal line defined by vertical, parallel lines through the ends of the rafter in question.
