DOMESTIC APPLIANCE.

T o all whom t may @071.06m u Be it known that we, ERNEST DIGKEY and RALPH L.l LEE, citizens of the United States of America, residing at Dayton, county of Montgomery, and State of Oh-io, have invented certain new and useful Improvements in Domestic Appliances, of which the followingD is a full, clear, and exact description.

This invention relates to improvements in portable power. units and more particularly to the type olt apparatus described -in the patent to Ernest Dickey No. 1,383,391, patented July 5, 1921.

In said patent there is disclosed a portable power devlce or power stand which includes a tripod support. for an electric motor having a driving pulley to which a drivenpulley of ama'chine may be belted. Generally, this type of power stand rests upon the iioor beside the machine to be operated, and

there is a spacingdevice provided. between the' power stand and the machine for bracing the power stand away from the machine yin order to keep the belt taut. y ,z l In the present'invention it is one of the objects to provide means'whereby the .sup-

port for the electric notor may be pivotally mounted, said support being suspended in mid air, that is,H without the weight of the support and motor Abeing transmitted directly to the 'iioor through legs attached to the support.l The motor and support arepivotally mounted so as to swing away from Ythe driven pulley of the machinel whereby the belt connecting the motor driving-pulley with the machine pulley will be held-taut by the weight of the motor and support.

In carryingout this aim of the invention, it is a further objecty to provide suspending means for vthe motor support whichemay be attached to the frame of the machine driven by the motor, said suspending means being adjustable in order to bring the motor pulley into alignment with the machine pulley.

A further Object is to'provide a Suspend-' ing means for the motor'support which iss .adjustable so that it may bel adapted for attachment to the frames of various machines whichcan be driven by tle motor, and to provide such adjustments as will be necessary to bring the motor pulley into the desired elevation with respect to the machine pulley aswell as to bring these two pulleys into alignment.

A further object of the invention'is to provide stop means'for limiting the fall of the motor-and supportv in vcase the belt should break.` Preferably the motor support is provided with legs' lby means ofv which the motor may be supported in positionv elevated fromtheioor when "the device is not in use, One of these legs may serve as a stop to limit the movement of the motor support in case of the belt breaking; Y/ A v a Other and further objects. and advantages of the present invention will be apparentjfromthe following description of a preferred embodiment thereof, reference being made to the accompanying drawings.

In the drawings,l Fig. 1 is a s-ide View of the portable'device embodying the pres'- ent invention, and attached to a machine to be driven by the motor;

Fig. 2 is a planview thereof, a machine frame being'shown in section .utaken on the line 2-'-2 o-.Fig l;

' Fig. 3 is -a'fragmentary plan view partly in section. showing theconnection between certain bracing members of the device and the motor supportgand y f Fig. 4 is a lperspective view 'of certain membersshown in Fig. 3, `the motor sup- 4port and the clamping wing nut being shown in detached relation.4

Referringto the drawings, a motor 20 having a stepped driving pulley 21 and a handle 22 is attached by bolts 23 to a support 24 provided with legs 25 by. means of which the motor may .be supported-.in elevated position when the power device is not in use.

The support 24 is provided with ears 26 apertured lat 27 and 28 or receiving respectively a rod 29 and a is slidable upon therod 29. The sleeve 30 is provided with a semi-cylindrical extension 31 which' cooperates with a similarly formed extension' 32 of the sleeve 33 which is also slidable upon the rod 29. When the sleeves 30,.. and n33 are caused-to movey together as will be, explained later these portions 31 and 32 will clamp around a pin 34 which is carrier-., by a clevis 35 which is screw threaded `iipon a tube 36.' Tube' 3'6 receives a rod n37 having a hook sleeve 30 which machine 43, such as a cream separator, for

example. l

The rod 29 carries two other clam ing sleeves 33 .which cooperate to provi e a clamping bearing for another pin 34 which has connections with the machine frame identical with those between the machine and the irst described pin 34. One of these sleeves is' pinned at 45 to the rod 29. Each of the pins 34 is attached to a clevis 35 by means of pins 46. The rod 29 is threaded at 47 to receive a wing nut 48 and to receive a locking nut 49.

Between spaced clamping sleeves 33v is a sleeve 50 having an extension 51 for receiving a tube 5 2 whichl is. telescopically engaged with a rod 53. The rod 53 is secured in adjusted position with lrespect to the tube 52 bymeans of a clamping screw 54, and each of the rods 37 maybe clamped in adjusted relation to eachA of the tubes'36 .by-'means 'of a clamping screw 55.

' To mount the power device v1n driving relation to a machine, the user will usually grasp the handle`22 and lift .the motor 20 intothe desired elevation with respect to the machine pulley 60, and will connect the pulleys 21'and 60 by means of a belt 61. The strut members 52 and 53 are then clamped 'in adjusted positio'n sothat the support 24.

will be suspended at 'the desired elevation, the -member 53 resting yupon the floor or jupon the base of the machine frame if convenient. .The bracing rods 37 are Withdrawn from the tubesv 36 so that the hooks 38 may engage the eyesl 39 ofthe clamps 40 which have been attached to the machine frame inl a convenient position; The strut members 52, 53 are so located as to bring the motor pulley 21 substantially into alignment with the machine pulley 60 and the brace members 36, 37 are so clamped in adjusted posi.- tion by theclamping screws.5 5 that the'axes of the. pulleys 60 and 21 .vill be parallel. -It is apparent that since the, clamps 40 and the pins 34 are spaced from each other that atrapezoid may be considered to be bounded by the brace members 36,137, a line joining the pin-s 34 and a line joining the 'clamps 40. So long as the pins 34' are free to turn with respect to the clamping sleeves 30, 33, and 33, 33, respectively, the angular adjustment of the bracing members 36, 37 with respect to the rodiA 29 may be varied. In case the machineJ frame is not constructedto facilitate attachment of the clamps 4() in a manner that will bring a line joining the eyes 39 into parallelism with theaxis of pulleye, then the bracingmembers 36, 37 may adjusted as to length and as to their angular relation to the rod 29 in order to locate the axis of the motor pulley 21 parallel to the axis of machine pulley 60, while these pulleys are brought into vertical alignment.

After the foregoing adjustments have been made the clamping nut 48 is screwed in along the rod 29',A thereby causing the members 30, 33, and 50 all to be clamped together, and the lock nut 49 is tightened down to secure the clamping nut 48 in position. The bracing members can not now swing with respect to the motor support 24 since the pins 34 attached to these members 4are prevented from turning with respect to theclamping sleeves carried by the rod 29. However, the motor support 24 is still free vto swing around the pivot rod 29, therefore it is apparent that the bracing meinbeis and ing taut the'belt connecting the motor and machine pulleys. As explained before the strut member and the bracing ineiiibeis are adjustable so that the pivotal supporting means can be secured to a variety of machine frames with the motor and support in correct driving relation to the machine. When this supporting means has been attached, the machine together with the supporting means constitutes a rigid structure from which the motor and its support is suspended.

In case the belt should break-the motor support 24 will swing downwardly, but one of the legs v-25will strike the floor and will act as a stop member limiting the movement of the motor support. AllVhile it is not .necessar to provide the motor support with logs it is preferable to do so in order that the motor may be supported in elevated position and be readily accessible wl en not in use, 'and in order to prevent the motor from being set down in refuse, dirt, or mud which accumulates on the floor or ground of the places where the present invention is used.

It will of course be undeistood that when provided with the supporting legs 25, the motoris'susceptible-of use in the same munner as shown and described in the aforesaid Dickey patent, that is, with the legs 25 resting on the iloor and supporting the weight of' the motor, one or both of the bracingmembers 36, 37 being connected to the work machine to holdthe power device in proper spaced relation to the work inachine.

While the form of mechanism herein shown and described constitutes a preferred embodiment of one form of the invention, it is to be understood that other forms might be adopted and various changes and alterations made in the shape, size, and proportion ofthe elements therein withoutv from the spirit and scope of the A to `supportthe motor.
