order to enable the use of the' device in cyl# uinders of small sizes.

yOther-objects of the invention are to provide a honing device or cylinder grinder having. a carrier in which 4is axially arrangedan ad] usting member movable longitudinally and having a plurality of mounts carrying cylinder engaging elements, each of said mounts hav an inwardly extending cam portion engaging said adjusting member and movable thereby radially into expanded po-` sition, the cam portion of each mount being arranged to one side of said adjusting member to enable said cam when in retracted position to move past said adjusting member,

thereby permitting the cylinder engaging elements to be contracted within a com ly small radius.

parative'- y Further objects of the invention are to provide a `carrier for honing devices of the class described, said carrier comprising end members and angularly shaped longitudinal members orspacers secured to said end members in properly spaced relation to provide radially disposed pleripherally opening pockets for receiving der engaging elements.

The'type of honing device to which my vention appertains contains expansible sticks or elements for engagingthe cylinder surface for honing or reninishing purposes. This type of device` is particularly useful for operating upon cylinders of internal combus-v he present invention is especially adapted for use in cylinders of comparatively small diameters, the device bein SO C011- structed as to permit the contraction of the elementslor mounts within a comparatively small radius.

Referring v by numerals to the accompanying drawings, 10 indicates the carrier member, 11 the abrasive sticks or'k elements, 12 the non-abrasive sticks or cylinder en aging elements, and 14 the spindle of the oningA device.

Thecarrier 10 consists of an upper end member 15, lower end member 16, and lonitudinally disposed members 17. As shown 8 v erein, the end members l15 and 16 are circular in shape and are provided in their opposed or inner faces with .grooves or seats 18 for receiving the corresponding ends of members 17.

The latter are preferably formed of ri ht angle shaped members having Ailangesl a, the apices of the angle beg spaced suitable distances vfromy the axis of the carrier. x 9o Tie bolts 19 have their upper ends 19a countersunk or otherwise seated in the upper endmember 15 and extend downwardly below the apertures formed in the lower end member 16. The'lower projecting ends of said vbolts 19 are screw-threaded and receive nuts 20 by 4means of which theend members are drawn together against the ends of angle members 17, therebytying said parts to gather.

The inner faces 21 of each iiange 17a are tionen mes pumps compressors and the like. '1g

lvertically disposed parallel with the opposed faces of the adjacent angle members, thereby providing vertically j disposed outwardly opening slots or pockets 22, the top and bottom of which are formed by end members -15 Yand 16, respectively. The spacing of the points and are screw-seated in flange 25a.

The lower end of shank 14 is bifurcated as indicated at 14a and said bifurcated ends are pivotally connected by pinsf28 to ring 26 at diametrically opposed points land at right angle to bolts 27. Thus a flexible connection is provided between the carrier and the shank so that said parts can occupy slight angular positions relatively to each other.

A rod 29 extends axially through the carrier,

members

15 and 16 being provided with axial apertures for this purpose. Thenpper end of this rod 'is provided with a screw thread, as indicated at 30, and exten'ds'upwardly above the flanged end 25a of extention 25. A manually adjustable screw 31 is screw-threaded on the threaded end 30 and is adapted when actuated to impart longitudinal movement to rod 29.v

Rod 29 has fixed thereon at points intermediate said end/members 15 and 16 a pair of blocks 32 which are spaced from each other. Eachwof said blocks is provided with a radially extending projection 34, the upper face of which is inclined upwardly and inwardly, as indicated at 35. The number of projections 34 corresponds to the number of pockets 22 and said projections extenda suitable distance thereinto and each is substantially of the same width as the width of the pocket, thereby serving to hold the rod against rotative movement.

Each pocket or slot 22 receives a mount 35. The width and the. length of each mount are substantially the same as the width and length of the corresponding pocket so that said mounts are free to move radially in said pockets but are held in proper operative positions.l

The outer end of each mount is provided with anoutwardly presented longitudinally disposed channel member 36 into which is received a stick or cylinder engaging element 37. This stick, whiclrmay be either of abrasive material, suchy as at 37 a, or non-abrasive materiahsuch as at 376, is securely fixed in thechannel and projects a suitable distance outwardly therefrom. The rear end of 'each Leo-asas 'i This operating engagement is effected by forming side walls 38a and 386 with upwardly and inwardly inclined faces 39, the angle of inclination of each face 'being equivalent to the angle of inclination of the faces 35 of projections 34. These inclined faces are formed by cutting out or notching portions of said walls as indicated at 40 and by cutting the lower ends of said side walls.

Side walls 38a .and 386 are disposed to each side of the center of the mount and the width between said side walls is greater than the diameter of rod 29 so that the deep side wall or flange 38a operates in a vertical plane disposed to one side of said rod. The other side wall 386 is comparatively shallow so that when the mount is in retracted orinnermost position, said side wall terminates short of the side wall 38a of the adjacent mount, which latter side wall operates, in the present. instance, in a vertical plane disposed at right angles to the vertical plane of said side wall 386, as shown in Figures 4 and 5. This particular disposal of the side walls with respect to each other and with respect to rod 29 permits the contraction of mounts 35 within a comparativelyv small diameter, thereby enabling the use of the honing device in cylinders of small diameters.

In order to prevent displacement of the mounts when they occupy expanded positions, such as shown in Figure 5, in which position the shallow side wall 386 has comparatively small surface contact with the corresponding wall 21 of the body member 17, a spring-pressed friction member 41 is pro-` vided in said side wall 386 for engaging face 21. In the present instance, this friction member consists `of a plunger exte-nding through an aperture formed in each wall 386. This plunger is provided adjacent to the inner side of flange 386 with a collar 42 against which bears one end of a coiled spring 44, the other end of which bears against the inner sidel of flange 38a. Thus collar 42 provides a bearing for the spring and also limits the outward movement of plunger 41. When the mount occupies position within the pocket, plunger 41 is depressed, thereby compressing spring 42 andr increasing friction engagement between the side wall 386 and the corresponding wall 21 of member 17. However, other forms of springs or friction members can be used to hold the mount against accident-al displacement.

The knurled portion 31a of screw 3l is of com aratively small diameter on account of the ifurcated ends 14a. In order to facilitate manipulation of member 3 1 and expand the mounts 35 with greater ease, a wrench 4 5 Ais provided. This wrench is'fornied with a central opening 46 which is non-circular and is adapted to engage the non-circular portion member 3l, only a partial rotative movement Slt of member 31 when said wrench is moved into raised position. Integral extensions 47 provide suitable handles for operating the wrench. When the wrench is disengaged the non-circular opening thereof is moved away from the non-circular portion Slband said wrench is free to rotate on member 311 The handles 47 are of greater length than the span between the bifurcated ends lac. Therefore, in using the wrench in combination with can be obtained and the wrench has to be dropped and disengaged from member 31 at the end of each operation and moved in oppol ets, ea
