s egm AULENBACK, F WORCESTER, ASSACHUsE'rrs BORING 'roon hpp lication filed May is, 1923. Serial No. 278,821,.-
This invention relates toimprovementsin boring tools and has for an'object the provision of a tool Ofilihe hand operated type "which may be quickly and readily set at I various angles relative tothework and its holder and whichwill maintain the bar and tool carried thereby; against chattering; and
' f springing out of proper position. v f I V Another objectof thejrinvention isthe pro-,
' .visionof a boring tool which is capable. of
v handling 'difi'erent types of bits and which i is provided withineans whereby a bitmay be securely held in place, or readily removed and another bit substituted. Y
1 With the above and other objects in view, I 1 a the invention furtherin'cludes thefollowing J novel features;and'details'of-construction, t0 be hereinafter more fully described, illus- I trated in the accompanying drawings and pointed out in the appended claim.
In the drawings 7 I i I Figural" is an elevation showing a fragmentary portion of a lathe with the invention Figure 2 is an enlarged longitudinal sectional view of the tool.- f g Figure 3is an enlarged section on the line of Figure ;2.
Figure, 4: 1s a similar View on the line 4-4 I of Figure 2. a
c Figure 5' is an elevation of the bit carrying ,flendofthetool, 1 V I Figure '6 is afragmentary view partlyin section illustrating a difierentftype of bit.
Figure 7 is a similar view showing a different position of the bit; 1
Figure 8 is alike View showing a bit ar I rangedat rightangles to the length fofthe ,"bar. f I l T I Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the-reference character 10 indicates the tool post of a lathe and 11 the work holder. 7
5 The tool-which is-designed'to be secured to the tool post comprises a bar 12 which is carried b yia holder 13, theholder being arranged at an incline with respect to the bar and being adjustably mounted upon the tool post as shown at 14. in l "shown in Figure 6, or 'a'single similarly: ar
' in Figure i a The'hore 22is designed to'receive a, rod 30, one end, of which isdesigned te' grip the The bar" 12 is cylindrical and is received 7 within a split sleeve 15' which is carriedfiby the holder 13. -This sleeve is provided with v I p anfapertured ear 16 through which extends a stud'17 This-stud has a threaded connec 7' tion 18 with the end of the holder 13 and has pivotally secured to its-outer end as shown at 19, an eccentric 20.- This ;eccentric jcar rise a handle 2-1,'and by reference'to Figure l "of "the drawings itfwill be seen that the eccentric may be'operated to secure or release the bar '12 so thatthe latter maybe longi tudinally and rotatably, adjusted upon the endof the holder 13.-
The bar 12 is provided with a centrallongitudinally extending bore 22 having an'enlarged portion 23 atone end. A toolre k 'cei'vin opening 24 intersects the outer end of "the bore 22 and this opening maybe are ranged at" a; transverse incline as '1 shown in Figures. 2 and? of the drawings, while an additional rightangularly arranged opening 25 may also be provided. If desired a single rightangularly arranged opening 27, maybe vprovided "to receive a relatively fiat b-itf28 as 7 ranged opening 29 may be provided as shown bit and forthi's purpose the*bit "1nay,be notched as shown at 31 in FigureQGfof the; drawings The opposite end" of the rodf3O is provided witha head 32 which'is slidable wi'thin-the'enlarged portion 23,01 the bore,
while. surrounding the'rod withinthis enlarged portion of the bore is. a coiled spring 33. The spring 33 bears against the head 32 and against a shoulder at the'inner 7 provided in the head 32 and by a set screw 37v 7 whose inner reduced end is positioned within 1 a a slot 38 provided in the block 35. This 7 '7 screwr37 is of th'eheadless type and its purpose is to hold the block against the head 32.
Threadedly mounted upon the inner end of the rod'12 is a cap 39; This cap engages the adjacentend of the block 35 andv may be threadedly adjusted upon the rod to force the block inward so as to tightly engage the rod 30 with the 'bit and hold the latter in posi 'tion. A handle 40 is carried-by the cap for convenience of adjustment. 7
a It will be apparent from the foregoing description and accompanying drawings that r the tool will be 'rigidlyheld in position upon thetool post and the holder may be adjusted with respect'to' the-post.
1 1niaddition, the; tool may beadjusted I within the holder sothat the bit will beaproperly' adjusted for the work. iBy removing thQiCEl-P 39 and loosening the screw '37, the bit: may bequickly removed and another bit" of a similar or difierent type substituted.
. The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim;
Having described the invention what is claimed is r V A boring t ool comprising a bar adjustably secured to a holder 'and having a tool receiving slot at one endand a bore extending fromthe slot to the other end there fif and having portion of the bore enlargecha tool holding'rod in said bore and engaging the v tooli n said slot, a notchedhead on the rod Within the enlarged portion of the bore, a
'spring'on .the rod between one end of the enlarged bore and the head to normally urge v .thefrod away from the tool, an adjustable cap threaded tothe bar and closing one end of the bore; said bar having the last named end provided with slots, a block engaged by the cap and engaging in the notched head and slots of the bar, a setbolt carried by the bar and; engaging the block to allow limited "movement of the latter and covered by the cap, and a handle for said cap. In-testiinony whereof I affix my signature.
