The present invention relates in general toimprovements in the art of rotary motion transmlssion,`and relates more particularly to improvements in the construction and operation of drives for transmitting rotary motion at an angle from a source of power to s. driven member. The primary object of my invention is-to provide an improved positive drive for transmitting Arotary motion from one' shaft or the like to .an-
other, which is simple and compact in construction,. emc'ient vin operation, and .flexible in its adaptations. A
Some ofthe more importantspecic objects of the invention are as follows:
l To provide a reversible gear drive for positively` and effectively transmitting rotary motion from' a driving. lto a driven member at denite speeds,
To provide 4an exceedingly compact anddurable power transmitting unit especially coo'perable with portable driving motors anddiverse tools,`
and which is adapted for quick reversal so as to propel the driven tools vat several speeds.
To provide 'an improved right angle driving assemblage embodying bevel motion transmitting gears which are journalled in anti-friction bearings eectively' housed 'within a sturdy casing.
:To provide an. improved rotary motion transmiittins device which may. be conveniently and eectively coupled to a driving shaft and suspended from the shaft mounting of the driving mechanism. y
To provide an improved right angle bevel gear drive in which the gears and `bearingsmay be y abundantlylubricated and are constantly protectively concealed. l
To provide an improved -power transmitting assembly for transferring'l rotary motion at an veniently applied to or removed from the driving source.
To provide an improved angle drive mechanism which is capable of being disposed in various positions to effectively transmit rotary motion from a driving shaft to a driven shaft. and which may be manufactured and sold for' diverse uses, [it] at moderate cost. /l These and other objects and advantages of l: Il lappears in the. original .patent but forms. no part of this 2 the present invention will be apparent from the following detailed description.
A clear conception of the improved features constituting my invention, and ofl the construction and operation of a typical right angle driving unit l'embodying the same, may be had by referring to the drawing accompanying and forming a part of this specification wherein like reference characters designate the same vor similar parts in the several views.v l
Fig. 1 is an external view or elevation of a 'typicn right 'ang-1e drive embodying the invention and associated with a power shaft to obtain reduced speed ofv rotation at the driven member; and 4 Fig. 2 is a central section throughthe assemblage of Fig. 1, taken alongA the line 2-2.
The gist of the presentinvention is the provision ofa compact angle drive for transmitting rotary motion from a driving source to a driven member at either of two speeds, and having means for facilitating manipulation and for readily mounting and drivingly connecting the unit, and while vonly one typical embodiment' of the invention has been shown and describedr it is not my desire or intent to unnecessarily limit-the utility of the improved features by virtue of this :restricted showing. It is moreover contemplated that specificv descriptive terms usedherein be given the broadest possibleinterpretation consistent with the actual disclosure.
Referring to the drawing, the improved motion iou'rnaluled for rotation in anti-friction bearings I2, I3 mountedyin the casing body B: a bevel gear Il secured to theshaft 8 between the bearings 9, l0 and-meshing with a bevel gear i5 secured to the shaft I I Ween the bearings I2, I 3; a sleeve coupling i6 interchangeably drivingly cooperable with identical polygonal sections or flattened portions I1 formed on the outerwardly protruding ends of the two shafts B, Il: a split mounting sleeve i8 clampingly cooperable with either of two similar outer annular surfaces I9 formed on th'e body 5 around the openings 8, 1; and a manipulating handle 20 and a cap screw or bolt 2| cooperable with ears 22 formed on the sleeve I8 end 26. The larger anti-friction bearings 8, l2
which coact with the shafts 8, Il, within the vopeningsv 6, 1 respectively, are of the sealed ball type of well known construction. being sealed by thin plates 21; and the smaller anti-friction bearings I0, I3 which coact with the inner reduced ends 28 of these shafts 8, respectively are of the roller type also of well known construction, being mounted within bores in the rigid boss 2l as illustrated in Fig. 2.
The bevel gears I4, I5 are of different sizes and may be firmly fastened to their respective shafts B, in any suitable manner. and the vball bearings 9, 2 are detachably secured within the openings 6, l by means of snap rings 28 while these openings 8, 1 are made sudiciently large to permit insertion and removal of the `adjacent gears Il, l5 therethrough when the snap rings 28 are removed. A removable split stop ring 29 may also be provided inwardly of the largest ball bearing I2, as shown, and the entire interior of the body 5 should normally be lled `with suitable lubricant which will-be confined within the gear chamber by the plates 21. An extremely compact rotary motion transmitting gear box or unit in which the gears Il, I8 are thoroughly lubricated and effectively protected, is thus provided.
The sleeve. coupling I6 which may also be formed of durable metal such as steel, has a socket at one end adapted tobe snugly applied to either of the flattened identical shaft portions I1, and is provided at its opposite end with internal screw threads 3|. while its medial portion Ais provided with a bore 82 of larger diameter than thethreaded shaft ends 25. The internal screw threads 3| of the coupling I8 may be formed to cooperate with the threads of the 'outer' shaft ends 2B .so that the coupling may -be'reversibly applied to either shaft 8, II, but
as shown', a rotary power shaft 33 has been threads 3| whereby theunit is adapted to drive the shaft at 'a' slower rotary speed than that Vof the shaft 8.
The power shaft 33 may be positively rotated at. any desired speed by an electric. or other type of rotary motor, and is journalled for rotation in aportable support 88 shown in dot-and-dash lines in the drawing. The mounting sleeve I8 for the. motiorrfv transmitting unit may be formed of resilient metal and is split longitudinally so that whenthe threaded Shanks of the manipulating' handle 2U and oi' the bolt 2| are released, the split sleeve I8 will spread and will be readily --removable' from or applicable to either of the Y annular surfaces I9 of the body 8, and to a similar surface formed on the support 35. The threaded shanks of the handle 20 and of the bolt l2| may be applied to either set of the clamping ears 22' which are rigidly attached to the opposite ends 'of the sleeve I8 adjacent to the splitrand the handle 20 may be utilized to place ldriven shaft' in any desired Position and to retain it in such position.
drivin'gly applied to -the internal coupling drivingly connected to the shaft the' other 4 I When the improved angular drive has been properly constructed and lubricated as hereinabove described, the screw threads 8| of the coupling I8 may be attached to the end of a rotarypower shaft 33, and one end of the split lsleeve I8 may be loosely applied to a support J5 associated with the power shaft,' as shown. The motion transmitting unit may then be applied with either flattened shaft portion I1 thereof snugly inserted within the flattened end socket jacent shaft of the unit and to simultaneously clamp the body 5 to the support 38.
Ii the power shaft 38 is thus drivingly connected to the shaft 8 as illustrated in the drawing, then the other shaft Il of the, drive will be rotatable at slower speed than the shaft Il. but if the power shaft 88 is interchangeably shaft 8 will be driven at higher speed, by virtue handle 20 may thereafter'be manipulated to direct and guide this rotating tool in any desired direction. i
From the foregoing detailed description, it will be apparent that the invention provides a simple and exceedingly compact and durable motion transmitting unit which is very exible in adapta- Y tion and may be operated at high or low speed Van positions iii-order to properly` direct and guide y the driven tool relative to the work in cramped with equal'efiiciency. The unitary gear housing body 5 is of sturdyconstruction and effectively protects the bevel gears Il, I5; while the antifriction bearings disposed on the opposite sides of eachof these gears and which also are protected by thehousing, provide etllcient .supports for the shafts 8. and for the gears Il,` I8. The shafts 8, II may also be disposed at any desired angle relative to each other. and by forming these shafts with similar protruding end por'- tlons l'I, 25 the coupling I8 may be reversibly attached to either end ofeithershaft and power may also be applied to either shaft endin order 'to obtain the selected speed of the driven shaft.
The improved mounting sleeve I8 also provides simple means for firmly supporting the unit at either'of the annular surfacesv I9. and the handle 20 and cap screw or bolt 2| serves to firmly clamp the split sleevevto the bodyv 5 and to a supporti. The handle 2|!` also permits convenient movement of thebody l' into various localities, thus producing an extremelyilexible assemblage adapted-for diverse uses. v The various parts of the geared rotary motion transmitting unit may also be readilyasse'mbled or dismantl'ed, and these units may-be manufactured' invar'ious sizes and for various purposes at mod-l construction or to the precise mode ofoperation of the angular drive herein specinc'ally illustrated -and described, for var-ous' modifications-within the scope of the appended claims may occur to persons skilled m the art.
