l (c1r 14s-4i) Claims,
provements to an adjustable saw' and more par#v teu-larly has reference to a. out-off saw which. isY mounted upon a vertical support shaft and which may loe readily adjusted to various positions' in the horizontal and. verticali planes.
The principal objects oi our invention` are: to` provide" a rotary saw' hating aI support means which will?- readily position the saw in a variety' of positions; wherein the elevation of the saw may" be readily and' easily controlled; wherein the radi-al distance oi thev saw fromits su'iipor-tv may be easily regulated; and wherein@ a tool` of great versatility as to' use is provided.
These, together witnvarious otherl objects of our invention which williy later become apparent as the following description proceeds, arerealized by our device; one embodiment of which. has been illustrated by way'of example onlyinthe attached drawings, wherein:
' Figure 1 is aside elevational View of the: device;
Figure 2 is a horizontal sectional View' being taken' substantially upon the section line Figure 1;
FigureA 3 is a side elevational View of the sole support;
Figure 4 is a top plan View of Figure 3;
Figure 5 is a rear elevational View of Figure l;
Figure 6 is an endview oi the supporting means in Figure l, certain parts being Yomitted iorrthe sake of clearness; and, l l
Figure 7 is a perspectn/e View ofLA an element of the support.
vR'zeierringnow more specifically to' the attached' drawings, whereinlike. numerals indicate sinii larl parts throughoutthe various Views, I6 designates the. base which mawv be formed' 0E a` generally rectangular plate of? any desiredsize or' materiali, upon` whichv is. detachably or' if" de` sired integrally mouted an u pstand-ing vertically disposed support standard I`2`. A generally rec-A tangul'ar carrier plate I4' is adjustably secured upontlie standard I2 by means oi? split clamps I6 and I8 at its upper and lower ends respectively. As will be seen, the carrier I4 may be vertically adjusted or may be swiveled horizontally upon the preferably tubular support or standard I2. A hanger plate 20 is swiveled to the upper portion of the carrier I4 as by a fastening bolt 22, and has its lower portion 24 laterally extended as shown in Figure 6, and has formed therein an arcuate slot 26 struck upon a radius about 22 as a center, through which rides a fastening bolt 28 secured in the lower end of the carrier plate I4, whereby the hanger 24 may be adjusted in various angular 2 positions upon thefvertically disposed carrier.'plater I4. A pair of` spa-ced' guide flanges 30 having in-`- turned shoulders 32 are' removably positioned upon the hanger Z0 by means of suitable fasten-f ing bolts 34, and serve to'guide and: retain agenerally rectarrg;ular slide 36'. Asv shown ini Figures 2 and "1' specifically, the slide 3B is forr'ied with' laterally extending shoulders Sie adapted for sli-ding engagement and retention by means of the shoulders 32 upon the guides 38?; The back, surface' of the' slide 3@ is providedy withA a lfiirgiltnal dinal slot 50 whichis' adapted tof clear the fas-teni:
ing. means 22 in the extreme upper' position. or the slide upon the hanger 2m .A1-t its: upper end, the' sl-i'deis formed with a transversely extending; arm.. or bar 4S, at trie extremities of. which are proavidedi apertures or bores 42 and 4d while'tliebody ofthe slide is provided with an aperture 4e for a1 purpose tobe nowv set-forth'.
aa A pair or rods 48 and 50' are adapted for' en2l gagement and support' iin the corresponding bores' l 42 and 414:'respectively',` while: a third. rodez is similarly associated with the borekllii'.. Atl their outerl extremities, the' rods 505,- 521 and 48 are' corineoted to' a frame member' 5e serves td strengthen and reinforce this-1 assembly which constitutes a; laterallyextending" support' for" al carriage to` be set forth: hereinafter. Thel rodsI 48S,- 50 and. 52' may be formed of? any desired' crosse section, length. or material'. Integrally extending from the cross-arm. 4e' is a lugv 56 provided a bore or aperture 53 for a purpose to be later set forth. The lower surface or' the hanger 2o, has mounted thereon. a bracket o2 provided wil-,ha lug S4 whose bore: or' aperture is aligned with` that` oi the boss as and: a supportingand operating snail;v 66 navi-ngi conventional handle 68,. is received in'V the 56 64.- Rigidly'sec-ured to the rod 66 are a pair of spaced collars 'lo between unionv is received the'. lug 56,.' said collars consti-tiring a support means; for journallir-'ig' and retaining the shaft or rod 6G uponA the hanger 2W. The lower" portion or the roda o6 is screw' threaded as--at 1'2, these screw threads extending through and cooperating with corresponding threads in the aperture of the boss or lug 64. From the fore going, it will be seen that the laterally extending arms 48, 50 and 52 constitute a frame work carried by the slide 36, and are adjustably mounted upon the hanger 20 by means of the collars 10, lugs 56 and 64. As shown best in Figures 1 and 3, a carriage or platform 14 is hung by means of suitable rollers 'I6 from the parallel bars 48 and 50, and is provided with a depending bracket or support 'I8 which journals the shaft 80 of a rotary saw 82 provided with a conventional guard 84. An electric motor-86 is mounted in any convenient manner upon the carriage 14 and is connected as by means of a driving belt 88 with the rotary saw.
From the foregoing, it is believed that the advantages and operation of our device will be now apparent. The carriage 'M and motor 86 and saw 82 may be adjusted in any desired manner upon the radial support arm consisting of the elements 48, D and 52. Simultaneously, or alternatively, the radial support arm together with the saw may be adjustable upon the hanger plate by means of the rod 66 and the aforementioned collars and bosses. Additionally, the hanger 2U together with the radial arm supports of the saw and motor, may be swiveled in a vertical plane upon the earrier plate I4 by proper manipulation of the locking bolt 28 in the adjusting slot 26. Finally, the radial arm supports may adjusted vertically of the standard l2 or horizontally thereabout by means of the split clamps I 6 and I8. By means of the foregoing, a power saw has been provided which is extremely ilexible as to its positions of adjustment and may be readily assembled or disassembled for storage or portability.
