Specification of Letters Patent.

Patented June 18, 1912.

Application filed August 8, 1910. Serial No. 576,083.

To all whom it may concern.

Be it known that I, HENRY TIDEMAN, a resident of Menominee, in the county of Menominee and State of Michigan, have invented certain new and useful Improvements in Gearing, of which the following is a full, clear, and precise specification.

My invention relates to a combination house-hold device, and particularly to a device comprising essentially a driving motor and coupling and transmission mechanism for connecting the motor in driving relation with various house-hold devices, such as sewing machinery, laundry machinery, grinding machinery, cleaning machinery, and so on.

One of the main objects of my invention is to provide a device of this character which is small and compact and light and easily transportable, and also one which can be adjusted to be efficiently coupled with the devices to be driven. 1

Another object of my invention is to provide the simplest most easily adjusted and eflicienttransmission mechanism.

v A further object is to mount compact yet sufliciently powerful suction cleaning mechanism directly as part of the device, and in general my invention contemplates improved, simplified and more reliable construction of the device ofthe class referred to, and a construction in which speed control can be accurately and readily adjusted.

The nature of my invention will be fully understood from the following specification and accompanying drawings, in which drawings- Figure 1 is a front viewthereof, Fig. 2 is a view of one side thereof, Fig. 3 is a view of the driving mechanism taken from the opposite side, and Fig. 4 is a top view of the driving mechanism shown in Fig. 3.

The supporting structure for the device comprises a top plate or bed 1 having at opposite sides pairs of pivot lugs 2 and 3 respectively, the lugs 2 pivoting the upper ends of legs 4l4l, and the lugs 3 pivoting similar legs 5-5, each leg terminating at its lower end in a universally jointed caster 6. The legs 4; diverge, as shown, and are rigidly braced by cross bars 7, the legs with the bars forming rigid leg frames. The legs 5 are braced by similar cross bars 8. The pivotal connection of the legs with the plate 1 is such that the leg frames can be swung toalso mounted on the table.

ward or away from each other to adjust the height of the plate 1 from the floor.

As shown in dotted lines, Fig. 1, the leg frames are substantially vertical, and the plate 1 is in its highest position, while the full lines show the leg frame spread apart to drop the table to a lower plane. Inorder to lock the leg frames in adjusted position a bar 9 is pivoted to an intermediate point of each leg 5, the front end of each bar having a longitudinal slot 10 whose upper edge has latch notches 11 for receiving a pin 12 extending from the opposite leg 4. A handle 12 connects together the front ends of the latching bars. Upon raising the handle the notches of the bars are carried over the pins 12, and the leg frames can be spread or brought together to bring the table int-o the desired plane, whereupon the handle is dropped to engage the nearest notches with the locking pins, to thus rigidly lock the leg frames in adjusted position. The casters being universally jointed enable this supporting structure to be moved readily along the floor.

Mounted centrally on the table 1 is a motor ,13 which may be of any type to give the desired power. The motor is protected by a housing 14 slipped thereover and secured to the table in any convenient manner. The rotating shaft 15 of the motor extends beyond both sides thereof and beyond the housing. The left end of the shaft immediately adjacent the outside of the housing carries a hub 16 mounting a friction disk 17 Adjacent one side of the disk a bearing frame 18 is mounted on the table and has an upward extension 19 for supporting a journal box 20 for a transmission shaft 21, which shaft extends horizontally and diametrically across the disk and at its other end is journaled in a bearing standard 22 Mounted on shaft 21 is a friction pinion 28 having a lateral hub 24 terminating in a flange 25, through which flange a key screw 26 is shown as passing to engage in a key-way 27 out along the shaft so that the pinion may he slid back and forth across and in contact with the face ofthe friction disk 17 and to be rotated thereby, the rotation of the pinion being transmitted to the shaft 21 and to a worm 28 secured to the shaft over the bearing frame 18. Below the shaft 21 the bearing frame 18 ournals in its sides a cross shaft 29 which mounts a worm wheel 30 which meshes with the worm 28. The shaft 29 on account of the worm and worm Wheel transmission train rotates comparatively slowly, while the shaft 21 will rotate at a higher speed. The end of shaft 21 projecting beyond the bearing 20 may mount a driving pulley whereby to transmit driving power through a belt to various house-hold appliances, such as sewing machines; or the shaft may directly receive appliances to be driven, such as fans, grinding stones, or the like. The shaft 29 extends a distance beyond its bearing frame 18 for connection with appliances to be driven at lesser speed, as laundry machinery such as wringers and washing machines, and coupling members 30 may be provided on this shaft to facilitate coupling thereof with such devices.

In order that the speed of shafts 21 and 29 may be regulated provision is made for sliding pinion 23 back and forth across the face of friction disk 17. As shown, the collar 31 surrounds the hub 24 of the pinion between the pinion and the flange 25, and from this collar a grip member 32 extends forwardly and receives a guide rod 33 supported in front of the shaft 21 from the frame 18 to the supporting arm 22 on standard 22. The end 32 of the grip member in front of the guide rod is curved so that the grip member can be readily manipulated to slide the pinion into the desired position of engagement on the friction disk in accordance with the speed desired, and a wide range of speed is thus permissible, ranging from full speed in one direction to full speed in the reverse direction, the pinion being at rest when at the center of the friction disk. This friction drive arrangement is sufficiently yielding to prevent breaking of the machine parts should the driven appliances become stuck at any time.

The opposite end of the shaft outside of housing 14 carries a hub 34 mounting a friction disk 35. Extending vertically and diametrically across the front of said disk is a shaft 36 journaled at its upper end in the horizontal end 37 of a vertical standard 38 extending from the table, the lower end of the shaft passing through and j ournaling the end of the horizontal extension 39 at the base of said standard, the shaft extending downwardly through the table for connection with mechanism to be driven. A rod 40 extending between the table and the end of the upper extension 37 of the standard serves to hold such standard rigidly in vertical position. On the shaft 36 is mounted a friction pinion 41 having a hub 42 terminating in a flange 43 through which passes a key screw 44 for engaging in key-way 45 provided in said shaft, so that as the friction pinion is moved vertically across the face of the friction disk the rotation of the friction disk will be transmitted to the pinion and its shaft. A collar 46 surrounding the hub between the pinion and the flange has a grip extension 47 slidably receiving the rod 40, this grip extension being shaped to be readily manipulated to slide the pinion across the face of the friction disk.

On the under side of the table 1 is mounted suction mechanism S, this suction mechanism comprising a fan case 48 which may contain a centrifugal fan 49. Secured to this fan case and communicating with the center thereof is an intake nipple 50 for receiving a hose 51 adapted for connection at its end with cleanin devices, such as suction sweeper heads. it a tangential point an outlet nipple 52 leads from the fan case for receiving the end of a bag 53 for retaining the dust and dirt drawn through the fan casing upon rotation of the fan. The shaft 36 may extend downwardly to directly receive the fan, or may be connected with the fan through suitable gearing which may be contained in a compartment 54 formed above the fan case. When the suction device is not in use the bag is rolled up and supported in rolled condition in spring clips 55 secured to the under side of the table, as

shown in full lines, Fig. 1. When the suction device is to be used the bag is removed from the clips and un-rolled, the bag being provided with ears 56 whereby it may be supported in open position'from one of the cross braces 7 of one of the leg frames. WVhen it is desired to collect the dust in the open bag, the outlet end of the bag is preferably held closed by a spring clamp 57 of well-known construction, comprising the cylindrical spring jaw 57 and its operating handles 57. When it is desired to blow the dust from the bag this spring clamp is removed to allow the outlet end of the bag 'to open.

The speed of the fan of the suction device can be accurately adjusted by shifting the pinion 41 into suitable position with reference to the disk 35, and by shifting the pinion beyond the center of the disk the direction of rotation of the fan can be reversed, if desired, to create blow instead of suction through the cleaning devices attached to the hose 51. The current supply to the motor can be controlled by a suitable switch 58 mounted in convenient position on the table 1, the supply conductors 59 terminating in a socket, not shown, for connection with the current outlet.

I thus produce a very useful household device which can be used to supply driving .ed to set the device for the most efficient connection or coupling engagement with the appliances to be driven, and the entire de vice is small, compact, light and easily transportable.

I do not desire to be limited to the precise constructions and arrangements which I have shown, as changes are possible which would still come within the scope of my invention, and I therefore claim the followmg:

1. In a household device, the combination of a vertically adjustable supporting table, a motor on said table having a driving shaft, a friction disk mounted at each end of said shaft, a cup-shaped bearing frame mounted on said table adjacent one end of said motor, a counter-shaft journaled in said bearing frame, a. gear wheel supported by said countershaft, vertical bearing extensions on said bearing frame, a transmission shaft journaled in said bearings, aworm on said transmission shaft meshing with said gear Wheel, said transmission shaft extending diametrically in front of one of the friction disks on the motor shaft, a friction pinion slidable on said transmission shaft but keyed to rotate with said shaft and engaging with said friction disk, a slide rod secured at one end to said bearing frame and carrying a grip member, said grip member being connected with said friction pinion so that sliding of said grip member on said sliding rod will cause shifting of the friction member across the face of said friction disk, and coupling mechanism carried at the end of said transmission shaft for adapting said shaft for connection with devices to be Operated.

2. In a household device, the combination of a vertically adjustable supporting table, a motor on said table having a driving shaft, a friction disk mounted at each end of said shaft, a cup-shaped bearing frame mounted disks on the motor shaft, a friction pinion slidable on said transmission shaft but keyed to rotate with said shaft and engaging with said friction disk, a slide rod secured at one end to said bearing frame and carrying a grip member, said grip member being connected with said friction pinion so that sliding of said grip member on said sliding rod will cause shifting of the friction member across the face of said friction disk, coupling mechanism carried at the end of said transmission shaft for adapting said shaft for connection with devices to be operated, mechanism to be driven rigidly mounted on the under side of said table, a vertical transmission shaft connected with said mechanism and extending diametrically in front of the other friction disk driven by the motor, a friction pinion slidable on said vertical shaft to be slid across said friction disk and thereby control the speed of the vertical shaft and the mechanism connected therewith, a vertical slide rod, and a grip member slidable on said slide rod and having connection with said friction pinion on said vertical transmission shaft.
