Application filed October 15, 1908. serial Ito. 457,913.
To all whom it may concern: Be it known that we, J orria E. L. LAnsoN, ajsubject of the King of Sweden, and AN- DERS HESSEL, a citizen of the "United States of America, both residents of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improves rents in Combined Saws; Bevels, and
the following is a specification. j I i The main objects of thisinvention are to provide an improved form of combination tool adapted to perform the functlons of a saw, rule, bevel, square, gage, and compass; to provide an improved attachment for a saw whereby the saw may be used asa bevel,
square or gage; and to provide an improved construction for such attachment and the saw whereby the attachment may be. readily attached to 'or remoyed from asaw, or may be accurately and quickly set to any of a,
plurality of angular positions on the saw.
These objects, are accomplished by the device shown in the accompanying drawing, in
which: 1
Figure 1 is a' side elevation of a combined saw, bevel, square, and markinggage emthis invention. Fig. 2 is a rear Figs. 3 and 4 are side and front views're: spectively of the attachment. Fig. 5 is an enlarged detail of the pin which serves as a middle rib 4 to pivot for the attachment. Fig. 6 is a frag-f mentary detail of the saw blade, showing the shape of the pivot hole.
In the construction show n in thedrawing, the saw-blade 1' has a-st-raight backandhas a scale'inscribed on one face along and parallel with the back edge. The blade 1 has perforations 2' at points corresponding to the lIlCh and, half-inch, or any other of its graduations. p 7 1, l
An arm or attachment 3 is pivoted to the blade 1 and adapted to be swung on its pivot to variousangular ositions with respect to the; back edge 0 the saw-blade 1. In Fig. 1 theattachment'is shown by full lines in the position for usingv the saw as a square or gage. Other positions of the at tachment are shown in dotted outline. I L
The attachment 3v is preferably of T-shaped cross-section and is split along its blade 1. The attachment 3 is pivoted to p the blade 1 by theYpi'n 7 bearing in therepivot pin. provide the slot 6 which per- 'm'lts the attachment to straddle the saw shank of the pin 7 makes it adjustable to poinpensate for wear of the recess 8, and also I has a clamping and centering effect for, securing the attachment accurately in any of its positions of adjustment. Y
A detent 9 cooperates with the'pivot pin 7 for securing the attachment 3. The detent 9 is depressed by'the spring 12 secured "to the rib 4 in any convenient manner, a screw being preferred, as it admits of a renewal of springs. To provide for adjustment of its tensiomthe springhas its endseated on' a projection 13 on the. rib 4, and the screw 14 hears between the projection and the detent :9. The pin 9 also has its shank tapered Where it engages the saw/blade, to provide for accurate centering in the aperture 15. r
The spring 12 is preferably seated in a notch in the top. of the projection 13 which prevents the spring from turning on the screw and insures that the pin 9 will always be directed by the springinto its seat. The. pin 9 has a cylindrical bearing in the boss on therib 4.
\ The perforations 15 in the blade 1 are .in thearc of. a circle having for its center the pivotal axis of the attachment 3, and are so located as to engage the 'dtent 9 for "looking' the attachment in certain desired angular positions, such. as 30,'45, 60, and.90. Lines may be inscribed on the blade 1 corresponding to the difl'erent positionsof the straight edge of the attachmeiitB, v
When it is desired to change the angle beis only necessary to lift the detent 9 clear tween the attachment 3 and the blade 1, it
of the blade and shift the attachment to the 1 desired position.. In each of the principal positions of attachment, the detent 9 will seat inv a perforation 15. When the attachment is at an unusual-position, as when used as a bevel, it may be held with sufficient security for the purpose by screwing down the The front face 5 of the attachment maybe graduated as shown .in Fig. 4. It is preferred to have the recess 8 so located that when engaged 'by the pin '1 the front face 5 of the attachment will register with the zero mark on the scale of the saw.
The operation of the device shown is as follows :When the device is in use as a saw, the attachment 3 may or may not be retained in position thereon. To apply the attach' therefore self-locking in each of its principal positions of adjustment. By screwing down the pivot 7, its conical shank 10 will tightly fit the notch 8 and therebyinsure accuracy of the angle between the straight edge 5. of the attachment and the back edge. of the saw. The conical shanks of the pins 7 and 9 insure accuracy of the setting of the attachment 3-, regardless of any'wear' which 'the pivot pin. e5
, may result in the apertures due to long con-.
tinned use of the device. The pivot pin 7 may be set so as to snugly fit the aperture 8, and it will then merely be necessary, upon attaching to or detaching-from the blade of the saw the attachment 3, to lift the detent pm 9 without changing the adjustment of By screwing the pivot pin tightly, the attachment may be clamped in angular positions where there are no apertures 15, with suflicient security for use as a bevel, and for this reason apertures 15 are provided only at such angles, where aocu-.
racy of adjustment isof great importance,
' and where it is essential thatthere shall be no possibility of slipping or accidental.
angles to the bac k of the saw, it isin .p0si' change ur thehdjustment. When'the device is to be used as a square or miter, such se-' purity of the adjustment is of great importance. When the attachment 3 is at right tion for use as a square or as a marking ga e. The perforations 2 are provided to pe mit a pencil point to be insertedtherein fo I marking when the device is used asa marking gage. The saw blade may be used as a compass by inserting apointed instrument in one of the perforations 2 as a center.
and by drawing the circle with a pencil inserted into another perforation 2.
The construction, shown in the drawings is a-preferred "embodiment of this invention,
but it will be seen that numerous details of the construction shown may be altered without departing from the sp1r1t of H115 invention.
