I GEAR MEcHAN SM.

To all whom it may concern Be itknown that I, HOWARD F. SNYDER,

a citizen of the United States, residing at connection with power driven washing ma chines, I have illustrated my invention in the accompanying drawings as applied to a washing machine, although I would have it understood that it is not limited to such use.

One object of my invention is to mount a horizontal shaft on a suitable support so as to swing bodily in a horizontal plane toward and away from the support without breaking operative connectioniwith the associated transmitting shaft, also carried by thesupport. This transmitting shaft is adapted to be operated fromra power shaft which, in

the preferred embodiment of my invention,

is mounted below the support which carries.

' the different parts of themechanismi When my invention is applied to a washing ma? chine this horizontal swinging shaft is the wringer shaft and the swingmg frame-work.

which supports this shaft is the frame-work of the wringer. The purpose of the horizontally swinging wringer frameisto permit use of the wringer in two pos1tions-one against the support or tub of the .washlng machine, and the other at approximately right angles to the first position, In the first position the wringer is used to wring the clothes from the tub of the washing machine into a wash tub or suitable recept ole placed beside the machine". In'the sec nd position the wringer-is used to wring the clothes from one tub into the other, while the washing, machine is operated in the usual manner with the cover closed.

' Another object of my invention is to pro vide means whereby the clutch which establishes operative connection between a pair of shafts carried on the support is automati cally controlled by the movement of a I I Specification of Letters Patent.

.hingedmember on the support. When my Improved gear mechanism is applied to awashing machine this hinged member is the top or cover for the tub, and the clutch which the cover controls throws the horizontal or wringer shaft into and out of operation. When the hinged member or cover is in closed position, the clutch referred to is open, and it remains openuntil the cover is moved into open position, whereupon the clutch is automatically actuated into closed position. In order to permit of the operoutwardly 'atright angles to, the suppdift, v

with the cover or hinged' member in closed posltion, andthe machine operated as usual.

- A further object of my invention 'is to a provide a motorjsupport or frame which is adapted to be readily slipped onand off the power shaft to make or break connection between the pinion on the motor shaft and the driving gear on the power shaft. No fastening devices are necessary toholdthe sup-- port or frame for the motor in operative position, the frame resting by gravity on a suitable bracket fixed to the support which carries my improved gear mechanism.

The above and other objects and advantages of my inven tion will become apparent from a detailed description of the accompanying drawings in which- Figure l is a side elevation'of my improved gear mechanism, the same being, for the sake of illustration, shown as applied to a washing machine, the latter being shown in cross-section for the sake of clearness't 'Fig. 2 is a side elevation of my improved gear mechanism, certain of the parts being,

Tn the accompanying drawings the support for my improved. gear mechanism is, for the sake of illustration, shown in the form of a washing machine tub 1 provided with legs 2 which are connected together by cross braces 3. If desired, an additional reinforcing rod 41 may be used between one or both pairs of legs. The top of the support 1 is provided with a cover 5 which'is pivoted to the tub or support 1 by means of hinges 6 so as to swing in a vertical plane. The part 5 will hereinafter be broadly referred to as a hinged member. 0

To the side of the support 1 is secured a casting indicated as a whole by C which comprises a main vertical body portion 7, an upper or head portion 8 and a bell-shaped enlargement 9 at the lower end. The casting is provided with lateral lugs or flanges 9 at the upper and lower ends, as shown in Fig. 7, for receiving suitable fastening devices, such as bolts 9 If desired the head 8 of the casting may be provided with a horizontal extension 8 adapted to rest on top of the support 1. A bolt 8 may be passed through the horizontal extension 8 and the support 1 as additional securing means for the casting C. The head portion 81s provided with a bearing opening 10, while a bearing opening 11 is formed at the lower end. of the main portion 7. The

openings

10 and 11 are in vertical alinement with each other and provide journal bearings for the vertical transmission shaft 12. To the upper end of this shaft is fixed the crank member 13 which, in the drawings, is shown in the form of a disk carrying a crank pin 14 at the outer edge thereof. The crank member 13 is provided with a hub 15 which rests upon the head portion 8 of the casting C and assists in holding the shaft against downward movement in its journal bearings. To the lower end of the shaft 12 is secured a horizontal bevel gear 16 which is arranged to mesh with a pair of bevel pinions 17 and 18, rotatably mounted on the power shaft 19. The horizontal gear 16 and the associated

vertical pinions

17 and 18 are housed with the bell-shaped enlargement 9 of the casting C. This enlargement is provided with diametrically opposite bearings 20 in which thepower shaft 19 is rotatably supported. The bevel pinions 17 and 18 engage the horizontal bevel gear 16 at diametrically opposite points so that the direction of rotation of the transmission shaft 12 depends upon which one of the two bevel pinions is operatively connected to the power shaft which is driven continuously in one direction by an electric motor or equivalent power device. The bevel pinion 17 has fixed thereto a clutch sleeve 17, while the other bevel pinion 18 is provided with a similar clutch sleeve 18. The

clutch sleeves

17 and 18 form parts of a double-throw clutch mechanism of which the main reciprocating member is the sleeve 22 slidahly keyed upon the power shaft 19. When this main sleeve 22 is in its neutral or midway position, as shown in Fig. 2, both of the

pinions

17 and 18 remain idle on the shaft 19. When the clutch sleeve 22 is moved into operative engagement with the sleeve 17, the bevel pinion 17 becomes coupled to the power shaft 19 and. the transmission shaft 12 is rotated in one direction. When the clutch sleeve 22 is moved into engagement with the sleeve 18*, the bevel pinion 18 becomes operatively connected to the power shaft 19 and the transmission shaft 12 is 1'0- tated in a reverse direction. The power shaft 19 has fixed thereto the large gear 23 which is permanently in mesh with the pinion llsecured upon the shaft of the electric motor M. The frame 25 on which the motor is mounted is provided with bearing lugs 26 through which the power shaft 19 passes, as best shown in Fig. 6. The motor M is rigidly attached to the "base portion of the frame 25 by bolts or other fastening devices 27. The frame 25 has on its under surface a rib 28 which engages the vertical bracket 29 secured to one of the cross braces 3 by means of bolts or rivets 30. The base portion of the frame 25 is thus normally 'hcld'in a substantially horizontal position. It will be observed that the motor frame or support 25 may be readily slipped on to the power shaft 19 so as to bring the motor pinion 21 into mesh with the main driving gear 23. A cotter 31 or other suitable device engages one of the bearing lugs 26 to prevent lateral movement of the motor frame 25 on the power shaft 19. By simply withdrawing the cotter 31, the motor and its supporting frame may be entirely withdrawn from the support which carries the gear mechanism of my invention. When the motor frame is in operative position, no fastening devices are necessary to retain it in this position,v

the frame resting by gravity on the bracket 29. Since the power shaft 19 forms a pivotal support for the motor frame it is impossiblefor the

gear members

23 and 24 to get out of mesh or to bind when the motor is operatively associated with the power shaft 19. The direction of operation of the motor} M is indicated by the arrow a in Fig.

I will now describe the means for controlling the clutch member 22 for operatively connecting one or the other of the

pinions

17 or 18 with the power shaft 19. The bellshaped enlargement at the lower end of the casting C is provided with a pair of diametrically opposite lugs 32 which carry the shaft 33. Cotters 34 prevent the shaft 33 from moving longitudinally in the supporting lugs 32. A bracket 35 is slidably mounted on the shaft 33 by means of perforated arms 36 through which the shaft passes. One ofthe arms 36 is provided with a yoke-shaped extension 37 arranged to engage in the annular recess 38 formed on the clutch member 22 by means of a pair of spaced shoulders 39. To the side of the support 1 opposite from the casting C is secured a pair of bearing brackets 40 for rotatably supporting the vertical crank shaft 41. The upper end of this crank shaft has a handle 42, while the lower end terminates in a crank arm 43. A connecting link or bar 44 is at one'end pivotally connected to the bracket 35 by means of the stud or pin 45, while the other end of the bar 44 is pivotally connected to the crank arm 43 of the shaft 41. The connecting link or bar 44 is suitably bent so as to pass below the gear wheel 24 and out of the way of the motor supporting frame 25. The handle 42 on the crank shaft 41 is provided with a ridged latching surface .46 adapted to coiiperate with a latch plate 47 fixed upon the hinged member 5 for locking the same in closed position. When the handle 42 is in the position shown in Fig. 1, the hinged member 5 is locked and the clutch member 22 is operatively connected to the pinion 17. This causes rotation of the vertical transmission shaft 12 in a certain direction. When the handle 42 is moved at right angles to the position shown in Fig. 1, the clutch member 22 is in its neutral or midway position, as shown in Fig. 2. In this position of the clutch member, both of the pinions 17' and 18 are idle during the rota tion of the power shaft 19. VVheIi the handle 42 is turned 180 from the position shown in Fig. l, the crank arm 43 will occupy the position indicated in dotted lines at 43 in Fig. 1 and the clutch member 22 is in operative engagement with the pinion 18, so that the transmimion shaft 12 now rotates in a directionreverse to that in which it operated when the handle was in the position shown in Fig. 1., It will be observed that when the clutch member 22 is in either one of the operative positions, the hinged mem- 46 of the handle 42 in firm engagement with the latch plate 47, a coil spring 48 is provided on the crank shaft 41. The upper end of the spring bears against the bracket 40 and the lower against a. pin or stud 49 on the shaft 41. The tendency of the spring 48 is to force-the shaft 41 downwardly, so

that the ridged locking surface 46 snaps into the notch 50 provided on the latch plate 47 when the handle 42 is in latching position. \Vhen the handle 42 is in open position the shaft 12 is essentially disconnected from the power shaft 19. This feature is of special advantage when my invention is applied to a washing machine for the reason that it compels disconnection of the agitator shaft from the power shaft before the operator can lift the cover. This prevents accidental injury to the operator by moving parts when the cover is raised to take clothes out of the tub. I do not herein claim broadly the automatic disconnection of the transmission shaft 12 from the power shaft 19 when the handle 42 is moved into unlatching position, because this feature is broadly claimed in my copending application, Ser. No. 620,101,

. filed April 10, 1911.

The hinged member 5 supports a central Vertical shaft 51 which is shown in the drawings as the agitator shaft of a washing machine. This shaft has fixed thereto a pinion 52 which is preferably inclosed in a. housing 53 secured on top of the hinged a member 5. A rack bar 54 is adapted to mesh with the pinion 52 for imparting an oscillatory movement to the shaft 51 as the transmission shaft 12 is rotated. The rack 54 is connected tothe crank member 13 by means of a swivel connection 55, so that the rack can move in a horizontal as well as a vertical plane. The swivel connection 55 is pivoted to the crank member 13 by means of the crank pin 14. The rack bar 54 is pivoted to the swivel connection 55 by means of the horizontal pin 56. In this way the rack bar 54 is free to swing in a horizontal plane as the crank member 13 is rotated without breaking connection with the pinion 52. At the same time the rack 54 may be readily swung about the pin 56 out of engagement with the pinion 52. The swivel connection 55 is preferably mounted loosely on the crank pin 14 so that the rack bar can be bodily removed from the crank member 13.

The vertical transmission shaft 12 has fixed thereto aclutch member 57 provided with teeth 58 adapted to interlock with the teeth 59 of the clutch sleeve 60 which is slidably and non-rotatably mounted on the shaft 12. The clutch sleeve 60'is provided with an annular recess 61 in which the free ends of a pair of arms'62 are arranged to engage. The arms 62 are fixed upon a rock shaft 63 rotatably supported in the openings 64 formed in the casting C. When the izs arms 62 are rocked downwardly, the clutch sleeve 60 is moved into locking engagement with the clutch member 57. The rock shaft 63 is at its outer end provided with an arm 65 which is fixed upon the shaft by means of a set screw 66,'or otherwise. The arm 65 is near its upper end provided with a slot 66 through which extends a link 67. The inner end of the link 67 is bent laterally at 68 and passed through an opening 69 in the vertical lug 70 mounted on the hinged member 5. This lug is in the drawings shown as part of one of the hinges 6. A compression spring 71 is coiled about the link 67. The inner end of the spring 71 is connected to the link 67 in any suitable manner, as by bearing against the transverse pin 72 on the link 67. The outer end of the spring 71 bears against the arm 65, a disk or washer 73 being preferably interposed. The free or outer end of the link 67 is provided with a pin 74 to which is pivoted the locking member 75. This member is shaped to straddle the link 67 so that the inner end thereof may rest firmly against the arm 65, as shown in Figs. 4 and 8, without danger of being forced upwardly out of locking position. When the cover or hinged member 5 is in closed position and the member 75 in looking position, the arm 65 is in the position shown in Figs. 2 and 8 and the clutch sleeve 60 is in its inoperative position. When now the hinged memher 5 is swung upwardly into open position, the spring 71 rocks the arm 65 downwardly and with it the shaft 63 and the arms 62. Consequently, the clutch sleeve 60 is moved downwardly into operative engagement with the clutch member 57. As will presently be explained, when the clutch member 60 is in operative position, it establishes connection between the transmission shaft 12 and a horizontal shaft which inthe herein illustrated embodiment of my invention is the wringer shaft. The closed position of the clutch sleeve 60 when the hinged member 5 is in open position, is shown in Fig. 4.

When the hinged member 5 is swung down into closed position the clutch sleeve 60 is automatically disconnected from the shaft 12 and the operation of the wringer shaft ceases. However, the wringer shaft may be operatively connected with the transmission shaft 12 even when the hinged member 5 is closed, by simply moving the looking member 75 upwardly into inoperative position, as shown in Fig. 3. When this is done the arm 65 is thrown downwardly by the spring 71 and the clutch sleeve 60 is moved into operative position, in precisely the same manner as when the hinged member is swung upwardly. To facilitate the adjustment of the locking member 75 into and out of operative position, the same may be provided with a handle piece 76 which is shown in the drawings in the form. of a ring. Also, the arm 65 is at its upper end preferably provided with a handle 77 so that the arm can be easily grasped and forced away from the locking member 75 when it is desired to move the latter back into operative position. It will thus be seen that the clutch composed of the members .58 and 60 is controlled by the two independently operable members 5 and 75 I will now describe the horizontally swinging shaft and the connections between the same and the clutch sleeve 60. To the side of the support 1 is fixed a bracket indicated, as a whole by B, which comprises a vertical portion 78 having a horizontal extension 7 9 at its upper end and a horizontal extension 80 at its lower end. The bracket B is secured to the support 1 by means of bolts 81 or other suitable fastening devices. To the bracket B is pivoted the bracket B which, like the bracket B, comprises a vertical portion 82, an upper horizontal extension 83 and a lower horizontal extension 84. The horizontal extensions of the two brackets are provided with vertically alined opening in the bracket B. To the outer end of the horizontal shaft 89 is fixed the bevel pinion 90 which is arranged to mesh with the bevel pinion 91 secured to the upper end of the vertical counter-shaft 92. The bevel gears 90 and 91 together with the countershaft 92 are preferably inclosed in a housing 93 which is provided with hearing

portions

94 and 95 for the counter-shaft 92. The bevel pinion 91 is provided with a hub ortion 96 which is adapted to rest on the bearing 94 and thereby hold the shaft 92 suspended in the housing 93. The connected portion between the

bearings

94 and 95 is not shown in Fig. 7, because the housing is shown in longitudinal cross section. The housing 93 is supported on the bracket arm 97. One end of this bracket arm extends through the head portion 8 of the casting C, as shown at 98 in Fig. 2. At an intermediate point the bracket arm 97 is secured to the support 1 by means of a bolt 99, as shown in Fig. 7 The outer end of the bracket arm 97 is provided with a perforated bearing extension 100 on which rests directly the bearing portion 95 of the housing 93. Through the opening in the extension 100 of the bracket arm 97 passes the lower end of the counter-shaft 92. It is to be observed that the axis of the counter-shaft 92 is in vertical alinement with the axis of the pivot bolts and 87 about which the bracket B swings. Consequently, when the bracket B is swung about its pivot the bevel gear 90 is free to roll around the associated bevel gear 91 without breaking connection therewith. To the extended lower end of the counter-shaft 92 is fixed a sprocket wheel 101. The clutch sleeve 60 has rigidly connected therewith a sprocket wheel 102. In the illustration shown in the drawings the sprocket wheel 102 is provided by forming sprocket teeth on the clutch sleeve (30. A sprocket chain 103 passes around the sprocket wheels 101 and 102 to transmit the rotation of the clutch sleeve (30 to the counter-shaft 92 and thence to the horizontal shaft 89. To provide additional steadying means for the bracket B, the placing arm 10% is bolted to the support at 105 and passes under the lower extension of the bracket B. The pivot bolt 86 passes through the opening at the outer end of the bracing arm 104. It will be clear from the above that as long as the clutch sleeve (i0 is in its upper or inoperative position, the horizo-ntal or wringer shaft 85) is disconnected from the transmission shaft 12. \Vhen the clutch member (30 is moved downwardly either by opening the cover 5 or releasing the locking member 75, the horizontal shaft 8.) becomes operatively connected with the transmission shaft 12.

The horizontally swinging shaft 89 is particularly useful when my improved gear mechanism is applied to a washing machine, in which case this horizontal shaft is the wringer shaft. \Vhen the operator wishes to wring the clothes out of the tub 1 he first unlatchcs the cover 5 by moving the handle 42 into unlatching position. As previously stated, this nnlatching of the cover 5 automatically disconnects the transmission shaft 12 from the power shaft 19, so that there is no danger of any moving parts injuring the operator when he manipulates the cover 5. After the cover has been swung into open position, the handle 42 is turned to throw the clutch member 22 into its forward operative position, and by this position I mean that which causes the wringer shaft 89 to revolve in a forward direction to wring clothes from the tub 1 into a suitable receptacle placed at the side of the tub. It

may sometimes be necessary or desired tooperate the wringer mechanism at the same time that-the agitator shaft 51 is operated to wash a batch of clothes in the tub. This is done by swinging the bracket B away from the support until the wringer occupies a position substantially at right/angles from its position against the tub, as indicated in dotted lines at 1V in Fig. 5. hen the wringer is in his position operative con nection between the wringer shaft 89 and the transmission shaft 12 is established by moving the locking member 75 upwardly as seen in Fig. 3, whereby the clutch sleeve 00 is moved into operative position. The wringer may then be used to wring the clothes from one receptacle into the other, while at the same time the agitator shaft 51 is being operated to wash the clothes in the tub.

The wringer may be provided with a hand wheel 106 for turning the wringer backwardly, as for unwinding clothes from the wringer rolls. Of course, this backward operation of the wringer shaft takes place when the wringer shaft is disconnected from the power shaft 19.

W'hile I have'herein shown one specific embodiment of my invention, I would have it understood that changes and alterations may be made by those skilled in the art without departing from the scope of the.-

invention as defined in the appended claims.
