Serial a... 543,218.
The present invention relates to improvements in electrical utility devices, and particularly concerns a stand having an adjustment for regulating the height of the tool with respect to the container for the material being operated upon. l
Such electrical utility devices are emment it is desirable, if not essential, co pro vide an accurate adjustment of height of the tool with respect to the vessel containing the material undergoing treatment. It has, heretofore, been proposed to ovide manual attachment means for regu ating the height of the motor bracket on the column, but this has been found in practice not to give a suflicient degree of accuracy or attachment. According to the present invention means are provided for securing the motor bracket to the column at approximately the correct position of height, together with means for adjusting the height of the column itself for determining the accurate positioning of the tool with" respect to the vessel.
Two forms of construction of such devices are shown on the accompanying drawings, in which:
Figure 1 1s a side elevation of a utility device assembly, showing parts of one form of adjusting device.
Figure "2 is a fragmentary sectional view substantially on line 22 of Figure 1. I
' Figure 3-is a side elevation of a modified form of the device.
- Figures 4 and 5 are sectional views substantially on line 44 and 55, respectively, of Figure 3.
Figure 6 is a sectional view on the line of Figure 4. h e
In the drawings," the utility device comprises a supporting plate 10 having an up-.
standing boss 11 thereon in which is slidab-ly mounted a column 12. On this column is mounted a bracket 13 supporting the motor 14. Beneath the motor is usually provided a housing 15 containing the reducing gearing by which is driven the shaft 16 o a tool 17 here represented as a beater, preferably two of which are used in practice cooperating in the well known manner. On the bed plate 10 is illustrated a member 18 for holding a vessel 19 in which may be placed the material to be operated upon.
The bracket is provided with a thumb screw 20 by which it may be clamped at a desired position of height on the column 12. Owing to the weight of the motor and its parts, it is usually found difiicult to establish the bracket 13 at the desired point of height at which the bottom of the beater tool 17 will be close to the bottom wall of the vessel 19.
A' recess 21 is provided inthe bed plate 10,
into which extends a horizontal swivel screw or pivot 22 for supporting the adjusting lever '23 which has one end engaged by the nose of an adjusting screw 24 which is threadedly mounted in the bed plate for-easy access,
while the other end of the lever 23 has a rounded-nose constituting an adjusting finger for engagement with the bottom of e supporting column 12. By rotating the adjustingscrew 24, the adjusting lever 23- may be rocked on its pivot 22 and therewith the col-v umn 12 raised and lowered. A'lockilfg screw 25 is preferably provided in the boss-11 for holdin the column 12 in its adjusted position. FVhen this locking screw-is clamped tight; the entire device including a vessel I mounted onethe bushing l8 may be lifted by the handle 26 forming a part of the bracket 13. V
In the modified formof construction 1 shown in Figures 3, 4 and 5 the bed plate 10a and boss 11a receive a sup orting/ column 120 which in turn has a brac et 130 with the motor 14a'mounted thereon. As before, a
ar casing 15a, shaft 16a and tool 17a are illustrated in conjunction with the vessel 19a. The upper end of the supporting column 12a in this form of construction is shown to have a plurality of notches 12?) into which is selectively received a spring detent 13b whereby the bracket 13a is held at a predetermined distance along the height of the column 120.
The column 12a is preferably square and fitted in square openings of the bracket 13a whereby the motor 14a is held in an invariable position against movement about the axis of the column. The lower portion of the column 12a, preferably at the vertical edges of the squared portion thereof, is provided with screw threads for engagement by a collar 31 which rests at its lower end upon the upper surface of the boss 11a. Beneath the threaded portions 30, the column 12a is reduced in cross section and given a general circular peripheral form comprisingthecylindrical portion 32 (Figure 4), having'a lon tudina groove 33 therein for engagement y the clamping screw 34 which is threadedly mounted in the boss 11a. A set screw 35 is provided in the collar 31 for engaging a at portion of the supporting column 12a.
This modified form is adjusted by bringing the motor 14a to approximately the desired position by releasing the spring detent 13b,
and then permitting it to snap into the notch 12b nearest the desired point, usually being just above the desired location, so that the tool 17a is yet a slight distance above the bottom wall of the vessel 19a. The set screw 35' is then released so that the sleeve 31 may be rotated. Set screw 34 may, if the sleeve 31 is to be raised, remain tightly locked. The sleeve 31 is then rotated and by release of the set screw 34, the supporting column 12a is moved downward, in such event, until the tool 17a is at the desired height. The set screw 35 is then on aged. Set screw 34 is likewise engaged with the reduced portion 32 while entering the groove 33 thereof, whereby to prevent rota-tion of the supporting column 12a and the parts carried thereby about the axis of the column, and also to make it possible, as before, to carry the device by the handle 2 When it is desired to raise thebeater 17a from its prevailing adjustment, the set screws 34 and 35 are released as before, and after 14' or 14a is held in a definite position and prevented from movement toward and from the side walls 19 or 19a. Likewise, aclampadjusted ing member 25 or 34 is provided to hold the co umn against rotation and to prevent it from bein withdrawn from the base 10.
In the rst form of construction, the adjustment may be lost each time the motor and tool is raised, following release of the clamping screw 20, but an easy adjustment is provided by the screw 24 so that resetting to a desired position is easily and quickly accomplished. In the second form of construction, the engagement of the spring detent 13b in the same notch 121) permits a return to exactly the same position, and if the same vessel 1931, or a vessel of corres onding vertical bottom dimension be emp oyed in conjunction with a suitable support, it is unnecessary to move the sleeve 31 even though the bracket 13a be entirely separated from the column 12a during the operation of withdrawing the vesel 19.
It isobvious that the invention is not limit ed solely to the form of construction shown, but that it may be employed within many ways of the scope of the append 2d claims.
Having thus described the in cation, what I claim as new and desire to secure by Letters Patent, is
