To all whom itmag concern: 7

Be it known that we, FRANK J. Mormon and JOHN L. Mormon, citizens of the United States, and residents of Newark, in the county of Essex and State of New Jersey,

have invented a new and Improved Gearing Driving Unit, of which the following is a full, clear, and exact description.

This invention relates to gear driving units, and has particular reference to a gear driving unit for chemical agitators, such as paint, pulp and sugar mixers.

An object of the invention is to provide a unit in which certain of the parts may be readily removed for repair and replacement without dismantling the entire apparatus.

Another object resides .in the provision of means whereby stresses to which the various parts are subject are more uniformly distributed, resulting in a stronger unit.

A further object resides in the provisionof means whereby the driving and driven shafts are so arranged that a plurality of units may be readily connected together and driven from a common source of power.

Astill further object resides in the particular construction and arrangement of parts hereinafter described and claimed and shown in the accompanying drawings.

The invention is illustrated in the drawings, of which v p Figure 1 is an elevation of the unit;

Fig. 2 is a plan view of the unit; and

Fig. 3 is a view showing a pluralityof units connected together,

As shown in the drawings, the unitis embodied in the form which is particularly applicable for attachment to a support 1, which, in the preferred application, is the top cover or platform of a chemical agitator which is in the form of a tank. To this platform is. suitably bolted or otherwise connected a casting having a U-shaped portion A and a rectangular portion B. These portions have a common leg 2. The legs 2, 3'

and 1 of the casting which extend vertically are provided with suitable bearing portions 5, 6 and 7 which are properly alined to receive a shaft 8, which is the driving shaft. The driving shaft is provided with the usual pair of pulleys 9 and 10, one of which is idle, adapted to cooperate with a belt 11 to drive the shaft 8. Any suitable belt-shifting mechanism, such as 12, maybe provided. These pulleys 9 and 10 are disposed within the U-shaped portion A of the casting.

Patented Dec. 2?,1921.

Within the rectangular shaft'portion B of 7 the casting is abevel gear 13 mounted on the shaft 8 and adapted to mesh with a-bevel gear 14 fixed to a shaft 15 which extends vertically substantially midway of the casting portion 13 and is journaled in bearings 16 and 17 in the lower and upper portions of this casting, respectively. This shaft 15 ex tends downwardly through the support or platform 1 into the'agitator or other receptacle and to it is connected any suitable agi- .tating means. It is, of course, apparent that this shaft may be connected to any other suitable device to be driven, regardless of whether it-is contained in a receptacle or ranged that the shaft .8 and the'shaft 15 are laterally disposed With respect to each other,

so that the shaft 8 can be extended from one side of the portion B to the other and be suitably journaled at each end. ticular disposition is effected by cutting the teeth of the bevel gears in such a manner as to permit of this offset of the driven shaft with respect to the driving shaft. Further,

' it will be noted that the bearings 6 and "(are provided with removable plates which are This pardisposed on the side of the bearing portions w opposite the shaft 15. On the other hand, it i will be noticed. that the bearing portions 16 and 17 are provided with removable plates disposed on the side ofthe respective bearrangement' of the removable plates of the various bearingportlons is convenient In that the shafts 8 and 1 5 and their cooperating parts may each be removed without disturbing the other. This is'particularly ading portions opposite the shaft 8. This arin the form of a removable plate, so that the entire shaft 8, including the pulleys 9 and 10, can be removed as a unit. 7

By supporting the shaft 8 at opposite ends,

in the casting portion B the strain which is ordinarily upon the driving shaft 8 when I nation of stresses and strain also enhances V hanr es the rigidity, simplicity and eflioieney extended to the end of the bevel gear l3 and yiism'a i n a ing rba i s, smal as 6, is substantially eliminated. This elimn the funrtioning and reduction of friction in she ver ie abaa i-ns p and 11 5 th shaft 15, so thatin this case the transm1s-' sion of power from one shaft to the other is efie ted with a minimum loss due to friction. This alsorresults in an-inorease-in the life ofthe parts far beyond that hitherto obtainable. i

ous gearing shafts and pulleys in the iform ofan integral unitary casting also onof the "transmission of power by means of i this device.

As shown in Fig, 3,by offsetting shaft 8 with respect tolshaft 15 it is possibleto exf tend theshaft 8evenbeyond its own ordi unit and connect by a flexible coupling 21 0f any suitable type toaeorresponding-shaft 22 of another'unit such as represented' bytheletter C in Fig. 8. Inthis figure, the bevel gear 13 is-mounted loosely around the shaft 8- andis adapted to mesh with theolutchmernber 13 which is rigidly connected to the shaft 8. Thiselutohmemher is operated by a clutch lever 14- to en gage the bevel gear l with the movement of the shaft 8 at will; This permits one or more driving units to be operated ata time regardless of the number of units of the series 'which may be operating. In this manner anynumber of units may be assembled and operated by a single source of power throughthe pulleysfi and 10l Hitherto in the operation of devices of this character it has notbeen possible to drive more than oneunit at a time fromtthe same source of power without the use of complicated connecting means.

It is, therefore, applargentithat I have provided a simple, compact and efficient unit which can be used byitself or n connection nism, with a minimum lossduekto friction out departing from the spirit, of the in- ;vention. a
