BUDG-ERS, OF LIBERTY COUNTY, TEXAS FRAMING TOOL Application led. 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 whereby timbers may be measured, to be Cut, at the desired angle, for use in buildings.

il, more particular' object of the invention is to provide a scale, or measuring device,

whereby rafters may be out on the desired 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 16 rafters may be readily measured to be out at any bevel desired to give the roof the desired pitch.

Viith the above and other objects in view this invention has particular relation to certain 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 on the line 3-3 of Figure 1.

Figure l 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 framework, shown for the purpose of better illustrating the use of the scale.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates a flat measuring stick having a slot 2 extending approxik mately from one end to the other thereof. rThere is an arcuate segment 3 fixed to one end of the base 4f and overturned from this base there is a flange 5 which lies adjacent the stick 1 and has the outstanding stud bolts G, 3 which project through slot 2 and whose outer ends are threaded to receive the clamp nuts 7, 7 by means of which said segment 3 is adjustably secured to the measuring stick 1929. Serial N'o. 345,297.

1. lThere is a squarehaving 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 recel ve the stud bolt 11 which projects out from one end of the base l 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 li. The free end of the arm 8 overlies the front face of the segment 3 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 valleycuts 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 yattached thereto whose free end is upturned into association 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 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, 2O are the rules 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

rules

25, 26, and their respective segments are obtained by means of the respective stud bolts 29, 3() which project from said bases through bearing in said rules and whose outer ends are threaded to receive the clamp nuts 31, e2.

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.

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 CFI Cal

the edge D of the rule 25 should then be brought to the same figure of the

scales

14, 21 respectively as designated, or shown in Figure 1, the thumb screws 7 12, and 31, should then be tightened with the bolt 11 at the outer end of slot 10. The implement should then be applied to the rafter or timber to be cut as shown in Figure 1. Lines should then be drawn along the edges indicated by the letters c, c to delineate the plate notch to be cut in the common rafter to receive the plate 36. Also amark should be made on the rafter or timber at the pointindicated by the letter B and the scale should then be lifted from the timber and the point A placed at the 'point mark B. This operation marks off one measure the length of which vcorresponds to the length of rafter for one foot of the width of the building, and measures of equal length to the number of one half of the width of the building in feet are then measured off on the rafter and a diagonal mark should be then made across the rafter along the edge D and the rafter cut olf along said line. The plate notch previously delineated along the edges c, c should then be cut out and the pattern as thus provided, should be used to cut out all of the common rafters. The ends of the rafters beyond said notches, should be cut olf so as to leave the desired extension for the eaves, in completing this pattern.

In order to form a hip roof rafter the straight edge E of the rule 26 should be brought or set at. the same figure used for the common cuts and then measured oft on the rafter as hereinbefore explained, using the point A as a starting point and marking along the edges c, c and D and also along the edge E and the cut for the beveled end of the rafter should be made along the lines drawn at the edges D, E. However each set of these short, or jack, rafters, should be madey two measures shorter than the previous ones and this will space the rafters, when erected into the roof structure, two feet between centers measured on the wall plate, this for the reason that each length of the measuring stick, taken at the desired pitch, equals one linear foot across the building.

The valley rafters are cut just the same as the short or jack rafters for the hip roof with the exception that no plate notch is necessary and a straight line should be drawn from the point AA along the adjacent edge of the arm 9 entirely across the rafter and the timber should'be cut ofi along said line. `liiorder to measure off the main hip rafters 37' and valley rafters 38, the device must be reset or re adjusted, and this is accomplished by moving the pointer 18 to the desired figure of the scale 17; that is, to the sameA figure `previously employed for the common cuts of the scale 16, and securing said pointer at said figure. rEhe straight edge 0 of theV arm 8 and the straight edge CZ 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 the coinmon rafters have been cut and while 'the arm 9 is positioned as shown in Figure 1 the adjustifient is then made 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 0, o will describe an arc and will be carried out closer to the adjacent margin of the iafter so that the arm 9 must be adjusted back or downwardly as illustrated in Figure 1 so as to give theproper depth to the notch defined by .the 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 rafter notch. The valley rafters should then be measured olf exactly as the common cuts were measured as hereinbefore explained, the number of measures necessary to give the required length, beingV one half of the width of the building in feet. Y

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 horizontal line delined by vertical parallel lines through the ends of the rafter in question.
