T. D. SADLER HANDSAW GUIDE Fil'ed Jan. 16,. 1924 5 Sheets-Sheet 3 www kor the like is preferably accommodate a pair ol' liller blocks 18. The closely7 spaced apart ends ot the straps constitute the inner' end oit the handle, and the straps carry a screw 14; provided with a winged nut 15 adapted to clamp the strap ends together, and upon a measuring blade 1G whichis pivotally mounted on the screw 141 and adapted to be swung thereupon into different angles, such as illustrated in Figure 2. A friction washer 1T of leather interposed between the upper face ot the blade 1G and the upper strap of the handle,so as to frictionally bind the blade 1G in adjusted position. A. retaining washer 1S is mounted upon the lower end oi the screw 14C and between the head ot the saine, and the lower strap ot' the handle.
The handle 11 is adapted to be held and clamped against the edge oit the work y a clan'ipingbar 19 which, as best shown in Figures 2 and Ll, comprises a Hat strip et apart to metal having a down-turned outer end 2O 'forming a clamping jaw adapted to engage over the edge ot' the work 10 remote :trom the handle 11. Theclamping bar is adapted to extend through a guide, slot 21 formed in the handle 11 intermediate the ends ot the enlarged part thereof, and the slot 21 is Jformed in a bushing 9:2 seated in the upper bloc-klo. The block 13 is provided with a wear plate Q3 at its outer side and above the slot 21. The lower edge ot' the wear plate f2?) is oll'set inwardly to provide a recess -t in the plate in which is adapted to work the nose o'li' a clamping and lockingl lever rlhe locking lever 25 comprises a tlat bar o'l suitable length and width for easy handling,and which has rounded opposite ends forming noses arranged to engage in the depression 2d one at a time, and the lever has extending 'from opposite sides headed studs 2G, which are spaced unequally from the adjacent ends of the lever 25 to provi-de working noses ot different lengths. The studs extend from opposite sides ot thelever 25, so that when one stud is extending downwardly,-tlie other stud is extending upwardly to 'form a handle. The clamping bar 19 is provided with a series of openings 27 of a size adapted to snugly receive the heads ot the studs 26 therethrough, and the studs 26 having their shanks ot sntlicient length to permit the overlapping oit` the heads ot the studs against the lower side ol the clamping bar 1S), atter the lever 25 has been fitted in the selected opening 27.
The studs 26 are so arranged with respect lo the adjacent ends ot' the claini'iing lever as to torni therewith cams` so that utter the lever 25 is fitted into an adjacent opening 2T at the outer side ot the handle 13, the lever 25 may be swung outwardly into the position shown in Figures 1, 2 and t, so as to first draw the clamping bar 19 through the handle 11 and bind the claw 2O ot the may be readily had metal `forming` a thickened back clamping bar against the work, and to then lock the clamping bar in such position by moving the lever 25 into a dead center posin tion. After this is done the blade 16 n'iay at which it After this is then The saw engaging member inay be ot any suitable construction adaptable :tor mounting upon the blade 16, but in the present case is shown as con'iprising a yoke or body portion QS composed oit a pair ot angle ineinliers having base portions 29 adapted to rest directly upon the tace ot the work 1t), and having their major portions extending np-r wardly in closely spaced apart relation, and secured in such relative positions by a bridge piece 230, which connects the upper ends ot the angle members. This yoke is adapted to receive therein a blade 31 ot a saw as shown in Figures 1 and 7. The angle members are provided at opposite edges with inwardly and oppositely facing vertical guide ways 32, which may be formed with removable strips 33 at their outer sides, so that access l to the guide ways 32.
Slides 3st are mounted in the guide ways 32, and are in the form ot spaced apart blocks 35 connected together at their upper endsr` and having` mounted therein a roller 3G arranged in the bight ot the slide` and adapted to engage the upper edge ot the saw blade 31. The lower ends ot the blocks 35 have inwardly extending contact jaws 37 which are closely spaced apart and adapted to engage against the opposite sides ot the saw blade 31, to hold the same from vibrating, and to also hold it in jtrne aline ment in the guide or yoke member 2S.
The back edge of the blade 31 is usually reinforced by an over-turned stil strip edge for the saw and this enlarged edge is accommodated be tween the Contact jaws 37 and the roller 36, the latter bearing directly on lthe edge and supporting the slide Sil on the saw. There is a slide 34 provided at each end of the guide member 28, so that the slides engage the saw blade 31 at longitudinally spaced points to thus maintain the saw blade in true alinement, and prevent rthe lateral. de AIlection thereof by the hand during the act ot reciprocating the saw.
The slides Het are adapted to rise and `tall with the saw blade not only in its rocliting and reziiirocating nioven'icnt. but also in the positioning ot the saw at dillferent angles on the work. ri`hc advantages ot such a structure. is that the bottoni ot the saw guide is open, so that the saw blade may be inclined at the desired convenient angle and it does not necessarily have to be held in a true horizontal position, such as is the case when using the ordinary type of mitre box.
and a winged nut 59 mounted on the bolt 55 may be used for clamping the blade 57 firmly to the handle when adjusted.
lt will be noted that there are no projections above the upper face plate 51 of the block or handle so that the blades 53 and 57 may be swung` lengthwise of the handle and the try-squaremay then be packed in a small space or in a shallow tool chest or the like.
The adj usting blade 53 carries a removable saw guide which comprises a base plate adapted to rest on the work, and which carries a second plate 6l of reduced width and which is spaced frein the plate 60 by strips GQ providing a channel 63 between the plates G() and 6l. The channel 63 is of suitable dimensions for slidably receiving the blade 53 therethrough. rlhe plate Gl carries a bearing block di therein with an axis of the bearing extending transversely of the plate Gl and in which is disposed the shaft portion (i5 of an upright G6 mounted on the outer end of the shaft portion and which carries a pair of spaced apart bars ($7 securedtogether at their upper ends only by rivets 68 or the like and between which is clamped a spacing block 69. A guide way or groove 70 is thus formed between the bars 67 for the reception of a saw bla-de. The groove 70 is of sufficient width to snugly receive the saw blade, so as to hold it from vibrating withoutv interfering with its free reciprocating movement. rlhe bars 67 have inner opposite flat faces to guide the blade and determine its true position across the work according to the angle at which the blade 53 and the saw guide is adjusted.
lThe upright G6 is mounted on the shaft (i5 so that the upright with its bars 67 may be swung toward the plane of the base plate- GO, so that the device may be compact and placed in a small compartment when not in use. In order to hold the upright 66 when raised, adjustable brace rods 71 are provided, one at each side of the upright 66 having their upper ends attached to an eye TQ mounted on the upper end ofthe upright GG and having their lower ends secured tov eyes 73 which are carried by the frame or lower portion of the saw guide at opposite sides of the bearing 64.
lVith this type of the device the parts may be readily folded into compact form, so as to occupy but small space, and the parts may be quickly and easily set up and applied'to the work in different positions of adj ust in ent.
'lhe clamping blade 57 may be provided withpencil receiving openings 74 arranged in suitable position and relation for drawing parallel lines on the face of the work when desired; i
lt is obvious that various changes and of blades adjustably rseaoce modifications may be made in the details of construction and design of the above spe cilically described embodiment of this invention without departing from the spirit thereof, suoli changes and modifications being restricted only by the `scope of the following claims lVhat is claimed iszl.
