I
The objects of the present invention are to facilitate installation in factories of sectional power-table outfits and to standardize ower-transmitter supporting means where v y the parts thereof may be interchangeably employed for left hand and right han'd transmitters, including the power-transmitter guards.
In a preferred embodiment of the invention, the present improved supporting means is em loyed in connection with the safetytable type of power-transmitters in which relatively shiftable d iving and driven clutchmembers are rotatabl journaled upon a hearing sleeve sustained by a hanger depending from the table-top or its supporting standard. In the present construction, the hangers are each secured for universal adjustment upon the table-supporting end-rails, and driving-shaft sections are disposed within but free of the bearing-sleeves sustained by the hangers, adjacent shaft-sections being connected by a flexible coupling which constitutes a support for one end of the shaftsections. The other ends of the shaft-sections are journaled upon the bearing-sleeves through the intermediary of the driving clutch-members.
In order to secure the hangers so that the bearing-sleeves carried. thereby are in substantial alinement, complemental bracketmembers are interchangeably secured upon opposite sides of the free end of each hanger,

present supporting means permits of reversi bly supporting each complete transmitter upon or with its hanger without changing the construction of the parts, thereby providing a standard construction capable of meeting the requirements of both left and right hand transmitters.
In the accompanying drawings, Fig. 1 is a View in elevation and partly in section of a portion of a.poWer-table constituting a preferred embodiment of the present improvement, the table being broken to more closely group the adjacent transmitters. Fig. 2 is a viewsubstantially on the line 2-2 of Fig. 1. Fig. 3 is a view substantially on the line 33 of Fig. 1. Fig. 4 is an elevation of a transmitter as viewed from the left in Fig. 1, the transmitter guard being omitted. Fig. 5
is a perspective view of the shaft-coupling,
with the parts thereof in detached relationship. Fig. 6 comprises perspective views of the complemental braoket-membersfor supporting the clutch-shifting lever and the transmitter-guard. Fig. 7 is a perspective View of the parts of the pulley-guard shown in detached relationship.
Referring to the drawings, to the under side of a sectional machine-supporting table 1 are suitably clamped inverted U-shaped rails,as 2, sustained by the two-part standards 3 which are vertically adjustable for raising and lowering the table 1. This supporting means for the table is more completely disclosed in a patent of G. M. Eames; No. 1,695,419, dated Dec. 18, 1928.
Each of the rails 2 may support one or more depending hangers 4: in a manner providing for a universal positioning movement of the For this purpose, the upper end of each hanger is formed with a rounded head 5, between which and the depending members of a rail 2 are interposed concavefaced washers 6. The head 5 is pivotally supported upon a rail 2 in reversible position by a bolt 7, passing through an aperture 8 in the hanger-head and through enlarged apertures in the washers 6.
Each hanger 4 has a transverse aperture at its free end to receive the end of a substantially horizontal bearing-sleeve 9 projecting from the hanger at one side thereof. Each bearing-sleeve constitutes supporting means for a sectional driving-shaft and the driving and driven clutch-members of a power-transmitter. As the present invention is not confined to the details of construction of the p0wer-transmitter itself and as a complete disclosure of the transmitter was made in our Patent No. 1,688,414, dated Oct. 23, 1928, of which the present application is a division, only a general reference will be herein made to the transmitter elements.
Slidingly disposed upon the bearing-sleeve 9 is a shift-sleeve 10 upon which is suitably journaled a driven clutch-member 11 having a widened periphery 12 to serve as a brakeengaging surface. Detachablv secured upon the clutch-member 11 is a belt-pulley 13, the hub of said clutch-member 11 being provided with a belt-groove 14 for the employment, if desired, of an extremely small pulley. J ournaled upon the bearing-sleeve is/a"driving clutch-member 15 formed with a-flanged rim 16 faced with a suitable friction-ring 17, said rim having sufficient weight to give to the driving clutch-member the eifect of a flywheel. The hub 18 of the driving clutchmember projects beyond the free end of the bearing-sleeve 9 to receive an end of a sectional driving-shaft section 19 disposed within the bearing-sleeve but free of contact therewith. Any suitable means may be employed to secure the end of a driving-shaft section within the hub 18, the form of securing means shown in the drawings comprising a well known clutch-coupling 20 disposed within a recess 21 in the hub 18. j
The shaft-section 19 is flexibly coupled with the opposite end of an adjacent shaftsection 22, of which the other end is supported by a driving clutch-member of an adjacent table section in the same manner as described in connection with the shaft-section 19 and hub 18. The flexible coupling referred to comprises a flexible disk or disk-ring 23' upon opposite sides of which are bolted the arms of multiple- armed spiders 24 and 25, the spider 25 being secured upon the driving clutch-member hub 18 and the spider 24 being suitably fixed upon the adjacent end of the shaft-section 22. It is to be understood that the described power-transmitter construction is duplicated in the successive transmitters usually employed for each table-section of a sectional power-table, with the exception that the outer end of the end drivingshaft section is journaled in a bearing sustained directly by the end hanger, as will be later described. Any driven clutch-member pulley 13 may be readily replaced by a pulley of different diameter, or as above indicated the clutch-member hub 14 may serve as a pulley, the selected pulley being embraced by the usual machine-driving belt 26.
Referring now more particularly to the present invention, means are provided for readily securing the shaft-hangers in positions in which the bearing-sleeves carried by said hangers are in substantial alinement, the hanger-securing means being so constructed as to afford supports for guards for the driving-shaft sections and power-transmitters,
and also for the several clutch-shifting 1evers.
The split'hub 27 of a bracket-member 28 is clamped by a screw-bolt 29 upon a bearingsleeve 9 at one side of each hanger. Disposed at the opposite side of each hanger is a complemental bracket-member 30 having triangularly arranged, apertured bosses, as 31, entered by bolts, as 32, passing through suitable apertures in the hanger and through similarly arranged apertures, as 33, in the bracket-member 28. This construction provides for firmly securing said bracket-members upon opposite sides of the hanger. Threaded into apertured ears in the bracket-member 28 are adjusting screws, as 34, one of which engages one side of a table-standard 3, the other screw 34 being employed for the same purpose when the transmitter is reversed. The opposite side of the standard 3 is engaged by an adjusting screw 35 threaded into an arm 36 integral-with the bracketmember 30. By manipulating said adjusting screws 34 and 35, the free end of a hanger 4 may evidently be readily adjusted to aline the bearing-sleeve thereof with the other bearing- ;sleeves and be firmly secured to the table standard in adjusted position.
The bracket-member 28 is formed with horizontally disposed arms, as 37 projecting from the hanger in the same direction as its bearing-sleeve and located at substantially equal distances from said bearing-sleeve. The arms 37 are provided with alined apertures, as 38, entered by a fulcrum-pin 39 of an angular shift-lever 40 having an upwardly disposed fork 41 in the spaced arms of which are secured trunnions, as 42. One of the trunnions 42 enters an aperture 43 and the other a segmental slot 44 formed in'opposite sides of a flange 45 on the shift-sleeve 10, the spaced arms of the fork 41 being disposed at opposite sides of the flange 45. The lower arms of the angular shift-lever 40 extends in the same direction as the free end of the bearing-sleeve and underlies said bearing-sleeve in substantially the-same vertical'plane. The free end of the shift-lever 40 is yieldingly connected with a treadle-actuated rod 46,.and a boss 48 of said lever and a depending arm 49 on the bracket-member 28. The lever 40 has an upstanding lug 50 provided in its upper sleeve is accurately located laterally. Slidingly fitted upon the rods 54 are apertured supporting-legs, as 56, projecting from the cylindrical portion 57 of a shield or guard surrounding the driving and driven clutchmembers. The underside of the shield-portion 57 is slotted to provide clearance for the brake-lever lug 50, said shield-portion 57 being preferably integral with a conical guard or shield 58 surrounding the shaft-coupling.
Fitted into the reduced end of the guard 58 is one end of a tube or shaft-guard 59 of which the opposite end is embraced by a cylindrical boss 60 on the bracket-member 30 of the next table-section transmitter-hanger.
Interposed between one of the guard or shield legs 56 and a boss 53 of a bracket-arm 52 is the hub 61 of a supporting guard-member 62 to which is detachably secureda belt-- guard 63 having similarly shaped, spaced segmental side-walls 64, one of which overlies the cylindrical portion 57 of the transmitter-shield; Either of the side-Walls 64 may obviously be secured upon the guard 62 according to whether it is to be used with a' right or left-hand transmitter.
It will be understood from the for going description that a bearing-sleevecar ying the clutch-elements may project from either side of its hanger and that without any change in construction the bracket- members 28 and 30 may be. interchangeably secured at opposite sides of a hanger, according to whether it is desired to employ a left-hand or a right-hand'transmitter.
The shaft-sectiom 19 is in the drawings shown as the end section of the driving-shaft, i. e., the short shaft-section at the end of the table. While this short section is supported at one end by a driving clutch-member, the other end is sustained by a ball-bearing 65 carried by a journal-box 66 sustained by the boss 60 of the end bracket-member 30.
