This invention has relation to an anchor for cylinder boring machines.
An object of the invention is to provide an anchor of novel and improved construction for fastening a cylinder boring machine upon an engine block having cylinders to be bored in'xed relation to the block and cylinders.
A further object is to provide an anchor for fasteningv a cylinder boring machine upon an engine block having cylinders to be bored in xed relation to the block and cylinders which will include desirable, new andimproved features and characteristics of construction.
And a further Object is to provide a cylinder boring machine anchoring device 4incorporating features and characteristics as hereinafter -set forth.

In the accompanying drawings forming a part of this specification,

4, the disclosure of Fig. 5, however, including an anchoring pin of .length less than that of the an choring pin shownl in Figs.l 1 and 2.
With respect to the drawings and the numer als of reference thereon,A Il) denotes thebase of a cylinder boring machine having a boring tool (not shown) `adapted to be' operative upon cylinlderstohe rebored of a cylinder block I l. As disclosed, the cylinder boring machine base l0 is supported onthe cylinderblock I!,and the an Chor of the invention is for-removably'securing said cylinder boring -machine to said cylinder block at a cylinder lf2 of the block otherthana cylinder to be rebored, vaccording to practice which is usual, the cylinderblock l l of course including cylinders, not necessary to be shown, additional to the cylinder l2.
The cylinder boringmachine base lllincludes' eachr otheradjacent the lower end portions of the uprightwalls of the base IU.
The new and improved'anchor is adapted -to be situated `within a cylinder, such as l2, of a cylinder'block, such as Il, adjacent a cylinder to be rebored, and a connector l5 constituting an upper unit of said'anchor'is for interconnecting the anchor with the cylinder boring machinevbase ID, or with va clamp (not shown) assembled with saidvcylinder boring machine base and including inwardly extending shelves such as' M.
'An intermediate unit of the anchor includes a `block of metal, or other rigid materiaLproviding a hollow elongated body I6 integrally supporting a laterally projecting element I1 ata side ofits upper end portion, a transverse Wall i8 adjacent said laterally projecting element and alined with said hollowvelongated body, and spaced apart. parallel legs 19, i9 situated at the lower end-of the hollow elongatedbody in spaced relation to the'transverse wall andthe laterallyprojecting element and in vertical alinement'with said hollow elongated body and said-transverse wall. An honoring-'pin 2li, vslidablysituated in atrans- "erse opening 2l in vthelaterally'projecting element lllat the iside of saidflaterally projecting element Vopposite the'transverse'wall i8, includes a beveled inner zend 22 and a rounded outer end Z3. lA stop pin 24, inthe transverselopening 2l adjacent the hollowelongated bodyv I his for limitingfthe extent of inward movement of theianchoring pin 2lb-and a set screw 25 is'for .retaining a springfpressed ball '26 innengagement with said anchoring pin to cause the anchoring pin to be irictionally slidably retained ,in said transverse xopening. A fixing-screw 21 in `a threaded opening .28 the upper enclof the laterallyapro jecting element I1, adjacent the transverse wall I8 and perpendicular to the anchoring pin 29, is adapted to be turned down against the beveled inner end 22 of said anchoring pin to cause the anchoring pin to be forcibly moved outwardly of the transverse opening 2|.
The hollow elongated body I6 is of generally rectilinear conguration and is adapted to detachably support an adapter 29 situated between the transverse wall I8 and the spaced apart, parallel legs I9, I9 at the side of said hollow elongated body opposite the laterally projecting element I'I substantially in alinement with said laterally projecting element and the anchoring pin 29 in direction transversely of the hollow` elongated body.
The adapter 29 is constituted as a flat, elongated base member 30 integrally supporting spaced apart, parallel, relatively narrow extension pieces 3|, 3| at one of its sides and spaced apart, parallel, comparatively wider extension pieces 32, 32 at its opposite side. The extension pieces 3|, 32 and 3|, 32 are in alined relation in direction thicknesswise of the flat, elongated base member 3U, and the extension pieces 3| 3| and 32, 32, respectively, are spaced apart a distance substantially equal to, or a trifle greater than, a measurement representing the thickness of the hollow elongated body I5. The extension pieces are in perpendicular relation to the flat, elongated base member 30 as shown, and the free side edges of all of said extension pieces include arcuate surfaces 33.
The flat, elongated base member 39 of said adapter 29 includes an opening 34 for removably receiving an attaching screw bolt 35 adapted to be turned home in a threaded opening 36 in an adjacent wall of the hollow elongated body I6 to cause the adapter to be detachably secured to and upon said hollow elongated body, and said flat, elongated base member 30 can be fastened up against the adjacent surface of the hollow elongated body either with the spaced apart, parallel elements 3|, 3| in overlapping relation to said hollow elongated body and the spaced apart, parallel elements 32, 32 projecting outwardly, or with said spaced apart, parallel elements 32, 32 in overlapping relation to the hollow elongated body and said spaced apart,
parallel elements 3|, 3| projecting outwardly.
When the elements 3|, 3| are in overlapping relation to the hollow elongated body the elements 32, 32 are adapted to function as eXtension pieces, and vice versa.
The construction and arrangement and the overall dimension in horizontal direction of the intermediate unit of the anchor, including the adapter 29 and the block of metal, or other rigid material, providing the hollow elongated body I6 and the laterally projecting element I'I, will be such that the iixing screw 21 can be turned down against the beveled inner end 22 of the anchoring pin 29 to cause the arcuate surfaces 33 of the extension pieces, 3|, 3| or 32, 32, as the case may be, and the rounded outer end 23 of said anchoring pin to be pressingly engaged against diametrically opposite portions of the internal cylindrical surface of a cylinder such as I2, about as disclosed in Fig. 1 of the drawings, thus to cause said intermediate unit of the anchor to be grasped within the cylinder against the possibility of accidental displacement.
It will be evident that when the adapter 29 is placed upon the elongated body I6 with the relatively narrow pieces 3| 3| in overlapping relation to said hollow elongated body so that the comparatively wider elements 32, 32 can serve as extension pieces, the anchor will be adapted to span a cylinder of greater diameter than when said adapter is placed upon said hollow elongated body with the comparatively wider pieces 32, 32 in overlapping relation to the hollow elongated body so that the relatively narrow elements 3|, 3| can serve as extension pieces. Stated otherwise, the adapter 29 constitutes an entity of the intermediate unit of the anchor which can be employed selectively to cause the overall dimension in horizontal direction of said intermediate unit to be increased to render said anchor capable of being grasped within cylinders of larger diameter and to cause the overall dimension in horizontal direction of the intermediate unit to be decreased to render the anchor capable of being grasped within cylinders of smaller diameter. And by employment of an anchoring pin such as 29 of suitable length, in connection with an intermediate unit employing an adapter such as 29 having extension pieces such as 3|, 3| or 32, 32 of suitable width, an anchor made according to the invention can be grasped in a cylinder of any of several different diameters. The principle incorporated in the anchor of the present invention is such that an intermediate unit of said anchor, by utilizing adapters such as 29 with extension elements such as 3|, 3| and 32, 32 of varying widths and anchoring pins such as 2|) of varying lengths, can be rendered capable of being grasped in cylinders which vary considerably in diameter, as will be apparent.
A lower unit of the anchor is constituted as an elongated bar 31 of metal, or other rigid material, having its midlength situated between and pivotally supported, as at 38, upon lower end portions of the spaced apart, parallel legs I9, I9. The elongated bar 3l comprises a clamping member of the anchor. It includes upwardly facing surfaces 39, 39 upon its opposite end portions adapted to be engaged beneath and against xoppositely disposed, lower surfaces of a cylinder block adjacent the lower end of a cylinder such as I2 in which said anchor is situated, as will be apparent from Figs. 1 and 2 of the drawings. Said elongated bar 3'I is supported upon the spaced apart legs I9, I9 for swinging movement in a vertical plane. The construction and arrangement will be such that said elongated bar 3'| .can be swung to acute angle relation to the intermediate unit of the anchor and passed down- 1 wardly through a cylinder, and the elongated bar can be swung while beneath the cylinder to substantially right angular relation to said intermediate unit. Or, in any instance when preferable, the intermediate unit of the anchor can be passed upwardly into a cylinder. T.t will be apparent that longer clamping members, as in Figs. 1 and 2, will be suitable for use with cylinders of larger diameter, and shorter clamping members, as in Figs. 3, 4 and 5, will be suitable for use with cylinders of smaller diameter.
Attention is called to the fact that the anchor which the invention presents need not necessarily be situated centrally of a cylinder such as I2. While the intermediate unit of said anchor will span the diameter of a cylinder in which the anchor is grasped, the lower unit, or clamping member constituted as the elongated bar 3l, can be situated at variable distances from the side surface of the cylinder, closer to or farther` from said side surface, as may suit convenience.`
Stated otherwise, a clamping member or elongated bar, such as 31, of the anchor need not be situated diametrically across a cylinder containing said anchor. Instead, the lower unit of the anchor can be situated at any location, found suitable in some instance or other, between a location where said lower unit is closely adjacent the side wall of a cylinder and a location where the lower unit extends diametrically across a cylinder.
The connector l5 is constituted as a vertical retaining screw 60 situated in an internal thread 4| of the transverse wall i8 of the intermediate unit of the anchor and having a horizontal annular Iiange or head 42 urpon its upper end. An upper portion of the vertical retaining screw 40, beneath the horizontal annular flange or head 42, is adapted to lie in the space between the inwardly extending shelves on the upright walls of the base l0, and portions of the lower surface of said horizontal annular flange or head 42 are adapted to be engaged against portions of the upper surfaces of said inwardly extending shelves. The lower end portion of the vertical retaining screw 4D is situated in the hollow elongated body IB beneath the transverse wall I8 and above the lower unit of the anchor.
Evidently, the anchor will be readily and easily removable from a. cylinder upon release of the anchoring pin 20 by partial withdrawal of the xing screw 21.
What is claimed is:
1. In an anchor for fastening a machine base upon and against a block including a cylinder,
a unit adapted to be situated within said cylinder in grasping relation to an internal cylindrical surface thereof, comprising a body member, an anchoring element situated in said body member at a side thereof, means for causing said anchoring element to be forcibly moved outwardly of said body member, and an adapter constituted as a base member supporting spaced apart, relatively narrow extension pieces at one of its Isides and spaced apart, comparatively wider extension pieces at its opposite side adapted selectively to be situated in overlapping relation to portions of said body member detachably supported on the body member at a side thereof opposite said anchoring element substantially in alinement with the anchoring element.
2. The combination as specified in claim 1 wherein said means is ,constituted as a xing screw in the body member adapted to be turned down against said anchoring element.
