located centrally between the side surfaces thereof, and this recess 3 extends vertically and intersects theupper surface t oi! the base (see Figs. 1, 2 and 5).
. Furthermore,.this recess has its opposite surfaces 5 arranged parallel to form a slide way for the saw-carrying bearing. This b earingcomprises a block 6 which has opposite plane suifaces?, designed to `slidably lit against the surfaces 5 of the slideway, and a Harige 8 which is designed to embrace the rear face of the `base 2;
An extension 9 is provided on said block, and this extension forms the lower half of the journal for carrying a shaft 10 which supports the circular saw 11. A bearing cap 12 forms the upper half of the journal earing and is seeuredto the extension 9 'by bolts13. j A; plate 14 has two opposite faces 15 which registerwith the faces 7 of the block 6 and also slide within the slideway provided by the recess. A stud 16 has one end rigidly secured within the plate, and the other end designed to freely pass through a hole 17 in the block 6.' This latter mentioned end of the stud 16wis provided with screw-threads and is of such length as to project beyond the rear surface of. the block 6 `(see Fig. 3).
A. handle 18 has a threaded opening which is designed to engage the threaded end of the stud 16 and bear against the rear face of the block 6 so that a rotation of said handle in one direction will serve to move the plate 14 and block 6 toward each other and to bind the `flange S of the block 6 against the rear face of the base 2 and` will also-serve to bind plate 14 against thel forward face of the base 2, thusI firmly securing theblock and plate tothe base.
The upper end of the plate 14 has a pin 20 designed to enter a cavity 21 in a forward overhung portion 22 of the extension 9 (see Figs. 3 and 5). The block 6 has an internally `screw-threaded hole 23 which is arranged vertically and is designed to receive the upper threaded end of a vertical post 2e,
the latter being rotatably mounted and seated within thelower end of the recess 3 (see ally operative shaft 2T, the latterl being jouring vertically.
The shaft '27 at its outer endis )rovided y w iere yv with a crank arm '2S and handle 29, the post 24 canf be rotated through the mediuni of said gears and shaft The shaft l0 has a collar O` which is rigidly secured thereto and forms the abutment 'for one face or the saw 11 anda nut 31 screwed onto the threaded end 32 or the sha'litlO,` serves to securely bind the saw to the collar 30.
The opposite end ing pulley 33 secured thereto which is rotatableby a belt 34. rlhis belt has its upper run 35 engaged by a take-up roller or pulley 36,\the latter being rotatable on an arm 37 which is pivotally mounted onla bracket 38 secured to the base 2 by a bolt 39. The arm 37l is acted upon by a coiled spring 40 which, in the present instance, is connected with the standard 1. The function of this roller 36 is to take up slack which occurs due to vertical adjustment er the saiv carrying shaft 10 as will hereinafter be more fully explained.
The base Q, adjacent to its upper portion, has tvvo extensions 4l and 42. These extensions at their loiver ends are provided with bosses 43 and 44 respectively. These bosses are provided with threaded openings 45,'
either of which can be engaged by a threadu ed rod 46 which is secured to a hand lever 47 y and is designed to protect 'through a mental slot 48 in depending portions 49 olf supporting arms 56 for the Work table 51. These arms 50 have holes 52 therein designed to be engaged by pivot pins 53 which are secured within the vupper portions of the extensions 41 and 42, the axes oit these pivot pins 53 being in a different vertical plane from the axes of the threaded openings 45 above referred to7 thus permitting the table 51 to tilt or turn on the pivot pins 53 Without greatly changing the relative position, with respect to the saw, oi? an open ing 54 in a block 55 through which the sanT extends (see Fig. 3). i
This block 55 is readily removable 'from the table proper and rests upon ledges 56 formed Within said table top so that the top ol" the block 55 is substantially flush with the top of the table 51.
ln operation, when it is desired to change the position of the sanT with respect to the top of the Work table 51. the handle 18 is loosened to relieve the binding action between the plate 14 and the block 6. The shaft 27 is then rotated through the medium of the handle 29, and since the post 24 cannot move vertically, the effect of the screwthreads on the post and the internal screwgear 25 i olf the shaft has a driv` .l said shaft 2,
heightrof the sanv Vhas 18 can be turned 6 and plate 14 to After the proper been attained, the handle to again clamp the block the'base 2 and the machine isi'eady for operation.
It will be noted that according to the arrangement of the belt illustrated, if the saW is lowered, the spring-40 will serve to pull theftakeaip roller downwardly and thereby takeup any slack in the run 35 of the belt. On the other hand, it' the saiv is moved upwardly, the spring 40 Will yieldin proportion to the upivard movement and thereby prevent undue strain on the belt.
lVhen it is desired to tilt the -table7 the hand lever 47 can be readily loosened and afterthetable top has. been rocked on the pivot pins 53', thc hand lever 47 can be again tightened to secure the table in the adjusted position. Y i 1 I preferably provide lingers 57 at the eX- tremetop of the base 2 which act as additional supports for the table when the latter is in a horizontal position and which also act as stops to permit the return of the table to a horizontal position.
l providea rail 55a on the top of the Work table 51 and provide this rail with two longitudinally slotted `arms 56a. Clamping bolts 57 are designedto extend through the table 51 and through the slots Within the arms 56a so that the rail 55 may be moved toward or from the san7 l1.
In Figs.` 6 to S inclusive, I'have shown a form of my invention Which can be made extremely small and is` ivell adapted for household use, manual training schools,` or other `places Where a serviceable little niachiiie is desired. VIn this form of my in vention7 l eliminate the means for raising' and lowering the circular saw such for eX-- ampletas the elements includingthepost 24, gears 25, 26, and handle Q9. f
Referring to Figs. 6, 7, and 8, 5S represents a base which provides a vertical slide-` Way 59` for a block 60, and a plate61, said bloclrand plateA being provided with flanges 62 and 63 Which respectively embrace opposite -aces of the base 58. The plate 61 has a stud; 640i similar construction to the stud 16 above described, and said stud` 64 extends through the block 60Landat its outer thread ed end is provided with a Wing nut 65 which serves to bind the plate 61 and block 60 to the base 58.
The block 60 has an extension 66 which forms a bearing for a shaft 67, saidsha'lt having a collar 68- thereon against which abuts a circular saw 69. A nut 70 ismount-` ed on the threadedend 710i the shaft 67 `collar 68.`
the upper face of the Connection between and is designed to clamp the saw againstthe The opposite end ofthe shaftli'l` is provided with a pulley 72. A 'work table 73 has arms 74 which are designed to rock upon pivot pins 75 which project from opposite extensions 76 and 77 of the base 58.
A threaded stud 791is Vmountedin the exand from the saw 69. This rail has bolts 85 which extend therethrough and which ride Within slots 86 formed within said table adjacent opposite ends thereof.
The rail 84 acts as a guide for the edge of the material to be sawed. I preferably insert a screw 87 through the plate `6l. and block 60, and while this screw forms a loose the block 60 and Vthe Y plate 6l, it serves to prevent undesirable jamming between said plate and block, so that when the wing nut is turned, the plate 6l and block 60 will move smoothly toward or from each other.
In this form of my invention7 the saw 69 can be adjusted vertically by hand after the wing nut 65 has been loosened, and the table 73 can be turned on the pivot pins 75 by loosening the wing nut 80 and can be secured in a tilted position by tightening on said Wing nut 80. Y l
While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth; but consider that l am at liberty to make such changes and alterations as fairly come Within the scope of the appended claims. l
