'A Q ` V Ray Alden Young, Willoughby, Ohio Application May 24, 1944, serial No. 537,151 ` s olaims. . V 1 (01.279-2) 2 , This invention relates to arbors, mandrels and similar tools. The primary object of the invention is to pro I small pin I5 projectíng outwardly therefrom ad jacent to the head and neck members II and III. The tapered shank I0' is designed to ?t into a regular collet chuck. vide a device of the type named which will quickly The cage member 20 is a tubular element which and easily engage and ?rmly retain an object to 5 has three large slots oropenings 2 I therein, which ? are parallel to each other and evenly spaced Another object is to provide a simple holder around its side. One end of the cage member 20 that is relatively inexpensive to manufacture and is provided with a peripheral flange 22. A small assemble and which is relatively simple and easy to use by inexperienced persons. IO slot 23 is cut into the cage member 20 and .the ?ange 22 as shown in the Figures Sand 6. A further object is to provide a device which The expansible sleeve member is a tubular ele grips or engages the Work uniformly around an Vrnent 25 which has a longitudinal slit 21 therein inside surface and which does not change the aXis which permits it to expand or contract as de ' around which it rotates regardless of whether it be rotated or machined. is closed or open. sired. These and other objects will become apparent from a reading of the following speci?cation and claims in connection with the accompanying drawing in which like parts are referred to and indicated by like reference characters and 20 projecting therefrom as shown in the Figure 6. wherein: Figure 1 is a side elevation, with parts broken away, of an arbor embodying this invention; One of its edges has a small tongue 26 The roller members may be ball or cylinder bearings 30 which ?t in cage member and which slightly larger than the member itself. When assembled, the the opening 2I of the have outside diameters thickness of the cage cage member ?ts over the head portion II, with the ?ange 22 adjacent to the neck portion I4 and so that the pin l5 Figure 2 is a vertical cross sectional view of the arbor taken along the line and in the direc 25 rests in the slot 23 in line with the tubular por .tion 20 of the cage member. A small spiral spring tíon of the arrows 2-2 of the Figure 1; I8 is also mounted aroundv the neck portion III Figure 3 is an enlarged sectional view of a part with one end thereof engaging the pin l5 and the of the arbor showing the relationship of the parts other end engaging the slot 23 of the cage mem when the clutch is closed; Figure 4 is a view similar lto that of Figure 3 30 ber. This spring I8 has a tendency therefore to >keep the pin l5 toward one side of the slot 23 but showing the clutch open; as indicated in the Figure 2.
