Plate I8 is provided with an aperture or recess as at 22 for the reception of be positioned parallel or angularly with respect a short stud 24 co-axial with the magnet assem to a base or tool. provided with a through aperture for the re Objects of the invention reside in the provi sion of a swiveled magnetic work holder com prising a permanent magnetic holding device swivelly or rotatably mounted in a support or supports for the purpose of presenting objects held thereto in angular relation to a tool or the like; and in which the working magnetic flux is turned on or off by means of a handle, the latter bly l6 for journaling the same, and plate 20 is ception of a shaft 26 axially aligned with the stud 24 and with the magnet assembly. Stud 24 and shaft 26 are secured by any desired means to the magnet assembly I6 for the purpose ‘of pro viding for rotation thereof relative to the de vice so as to turn the effective flux from the magnet on and o? more or less as more fully de being capable of assuming operating positions scribed in Patent No. 2,268,011, dated December and another position ‘wherein the handle is lo cated in out-of-the-way location relative to the support on which the magnetic holder is mount ed, so that the magnetic holder may be swiveled 30, 1941. or rotated without interference on the part of the handle. . . A supporting bracket or the like2B is used to mount one end of the magnetic holder and is provided with a journal rotatably holding a large boss or the like 30 which is secured to plate [8 or which forms an integral part thereof. An Further objects of the invention reside in the 20 other bracket 32 supports the other end of the device and is constructed similarly thereto for provision of a permanent magnet work holding rotatably supporting a large boss 34 which is se device having a rotatable means for turning the cured to or forms a part of plate 20. By reason holding flux on and off, said rotary means being generally aligned with journals rotatably or. of the bosses 3!) and 34 it will be seen that the swivelly mounting the holder for the purposes 25 magnetic holding device may be positioned either horizontally or with the top plate vertical or at aforesaid, there, being a co-axial means, such as any desired rotative angle. a shaft, extending through one of the journals ‘The boss 34 is provided with a central open and terminating in a handle for operating the ing co-axial with the magnet assembly [6 for same independentlyvof the rotated position of the holder so that the latter may be positioned where 30 the purpose of receiving the shaft 26 there through, it being noted that shaft 28 is fast to desired. without disturbing the setting of the the magnet assembly for the purpose of rotating handle and whereby the handle may be actuat the same relative to the housing for the holding ed to turn the holder on or off independently and device. Shaft 26 extends slightly beyond the end regardless of the position of the magnetic work of the boss 34 and terminates in a reduced ?at holder. . Other objects and advantages of the invention will appear hereinafter. Reference is to be had to the accompanying portion 36 which pivotally receives the bifurcat ed end 38 of a handle 40 by means of a pin 42. The boss 34 extends outwardly of the end of bracket 32 at one side only of the boss as shown drawings, in which Fig. l is a plan view showing a form of the 40 at 44 and this construction provides a pair of stops cooperating with a pin 46 to limit the ro invention; tation of handle 40 to a 180° swing which is all Fig. 2 is a view in side elevation, with part that is necessary to turn the magnetic assembly I6 from off position to on position as explained Fig. 3 is a longitudinal section through the de 45 in the above identi?ed patent. Handle 40 is also vice; pivotable on the pin 42 to the dotted line posi Fig. 4 is a view in end elevation showing the tion as shown in Fig. 2 aligning the handle with device in angular relation; and the shaft 26 for a double purpose, i. e., remov Fig. 5 is a transverse section through the de ing the handle from the operative path of the vice. machine in which the holder is used or the tool The present invention is illustrated as applied thereof, and also to allow a full 360° revolution to a permanent magnet work holding device or of the holding device without interference be chuck comprising a bottom plate It, a top plate tween the handle and the base of the bracket 32 l2 which may assume various con?guration-s as or the machine ways to which the latter is bolt desired, the top and bottom plates being secured ed. A collar 48 is provided for showing degrees together by any desired means such as screws of inclination thereon with reference to some or bolts l4 and shaped so as to provide a cavity ?xed point on the exterior of the bracket 32, lengthwise thereof. This cavity provides for a collar 48 being swiveled together with the boss 34. rotary magnet assembly indicated at It which The present swiveled magnetic work holder extends substantially the length of the work holder, the latter being closed at the ends by 60 may be turned to any inclination desired or may in section; v 3 2,409,017_ 4 be used with the work surface horizontal or verti cal or at any angle in between. However, when the holder is rotated the shaft 26 and handle 40 rotate bodily therewith and to the same degree so that regardless of the position of the holder, the magnetic condition thereof is undisturbed; and on the other hand shaft 26 may be actuated by handle 40 to turn the holder on and oif at any rotary operating member in the housing gener ally co-axial with the holding device, and means to rotate the ,rotary member, said means extend ing through a bracket. 9.
