- Thelcustomaryloose sleeve 14 encloses the body as shown.
- the reduced inner end 15 ofthe spindle 7V is carriedfby abearing which slides within the tube'2 ⁇ andis particularly shown in igures L and 5.
- This comprises inner and outer raceways 16 and 18 between which are rollers 17.
- va shell 19 which acts asaretainer.
- An end piece 2 0 is 'fastened in place 'by a .screw orsimilar Jfastening member near the end 21 ,of the spindle.
- the gears are mounted'freely on the spindle andheld in position in the following manner.
- the gear 27-bears at one end againstone of the hardened :washers 22 vand yat the other end against a shoulder on the spindle.
- the other end Yof the gear 26 abuts against a bearing 28 which lfits tightly on the spindle.
- the key 32 fits in a longitudinal slot 33 -in the spindlel yand has a projection 34, passing through a slot 35 -in the sleeve BOand-tting within anannular groove 36 von the inside kof the shifting member 3 1.
- the lrey must rotate with the spindle, while the shifting member 31 only has a longitudinal movement on the sleeve 30, and the groove 36 is necessary to permit rotary movement of the key independent of the member 31 but to insure that the key will move longitudinally with said member.
- the member 31 is provided with a cut out 37 whichfits over the driving rack 25, and with a eut out 39 for a purpose hereinafter mentioned..
- the member 31 has a projecting sharp edge 40.
- the key 32 is springpressed outwardly by a. spring 41 in the slot 33 and is adapted to couple the spindle to either or both of the gears 26 and 27.
- These gears are provided with internal ratchet teeth 42 having straight faces on one side and inclined faces on the other. lhen the parts are in the position shown in Figure 4, the key is engaged with the teeth of the gear 27, and
- the key may be set to engage both gears and make a rigid tool when the parts are fully extended, fully contracted, or in any intermediate position,.thus enabling the length of the tool to be varied within considerable limits.
- the shifting member 31 and key 32 are moved to either of the three positions in the following manner.
- a rack bar 43 is carried by two headed screws or rivets 44 and 45 which pass through slots in the bar adjacent its ends. Springs 46 lie between the heads of the screws 44 and ⁇ 45 andthe rack bar 43 and normally press it outwardly.
- the rack bar 43 is provided with a pin or bent lug 48 adapted to t in either of three holes A, B and C in the casing 2, and hold it in either of three positions, the parts of the other elements moving to positions designated by lines A, B and C upon Figure 2.
- the rack bar is also provided with a finger piece 49 which extends through a Slot 47 in the. casing 2, the slot and finger piece being protected against accidental displacement by a guard plate 5() provided with an opening permitting engagement of the linger piece by the. finger.
- the rack teeth of the bar when pressed inwardly by the finger piece 49, will engage the sharp edge '40 of the member 31 and said member can thereby be moved to either" of. the three positions designated. Said rack bar 43 moves freely over the shifting member 31 at all times.
- Figures 8 and 9 show certain modifications in lthe bearing for the end of the spindle, and to save space, the upper and lower halves of each figure show modified forms.
- the inner race way and rollers are the same as in the firstform, but the outer raceway 18l is a cylinder, and the shell 19a is machined with a. flange touching the reduced portion 15 ofthe spindle and against the washer 22.
- the inner raceway is the same, but the outer raceway 18c has an outwardly projecting flange at one end and an inwardly projecting flange at the other, the latter taking the plaeeof one of the washers 22 and also' providing means wherein the inner ends of the rollers 17C are pivoted, their outer ends bearing in a washer 61.
- the operation oit the device is believed ⁇ to be clear from the above description.
- the member 28 will also be provided With vout outs for the driving rack 25 and theshifting rack 43 which have not been particularly .identified on the drawings to avoid confusion. o
- the invention provides a single clutch element which canbe moved to engagewith either or both gears, and thus cause the spindle to rotate in either direction, or hold it against rotation vin any position.
- a separate means vis also provided to prevent the operation of the spindle When in either fully extended or fully contracted position.
- the guards for the finger pieces 4 9 and 52 are of importance in preventing accidental displacement of the mechanism when set as desired.
- Experience demonstrates the tool to have over twice the efficiency of any other automatic tool of this type.
