2 Claims. (Cl. 248-23) This invention relates to supports such as machine or motor bases and to improved means for adjustably supporting an electric motor or other machine thereon.
It is one of the objects of this invention to provide a machine base which is substantially of two-part construction including a main supporting base and a slide adjustably movable therealong.
Another important object of the invention is the provision of simple and easily operated adjusting means for the slide on the base.
A further object of this invention is to provide a sturdy motor base which is extremely simple of construction and which, by virtue of such simplicity, is reduced to two primary relatively movable parts having freely operating means associated with said parts for the purpose of adjustably positioning said parts with respect to each other.
Another object of the invention is the provision of a floating type of adjusting mechanism of simple construction which is non-binding, easily operated and easily assembled or disassembled on the base and slide.
Other objects and advantages of this invention will become more apparent as the following description of an embodiment thereof progresses, reference being made to the accompanying drawings in which like reference characters are employed to designate like parts throughout the same.
In the drawings:
Figure l is a top plan View of a motor base embodying my invention;
Figure 2 is a bottom plan View of the base shown in Figure l;
Figure 3 is an end view of the base shown in Figure l looking in the direction toward the left hand end of Figure l; and
Figure 4 is an enlarged sectional View taken on line 4 4 of Figure l.
In carrying out my invention, l have provided a construction which is of extreme simplicity in that the motor base comprises but two main units relatively slidable and adjustable by means of a simple and freely operable mechanical advantage adjusting means.
Referring more particularly to the embodiment of the invention illustrated in the accompanying drawing, the base comprises a base member A and a slide B. The base A is fabricated from sheet metal providing an upper table or platform 1 which may be of rectangular form as il lustrated having opposite and contiguous side walls 2 formed to extend downwardly and each terminating in oppositely and outwardly disposed longitudinal flanges 3 provided with bolt holes 3 and which preferably lie in a plane parallel with that of the top or table 1, thus providing a frame or base which is of substantially inverted U-form, as illustrated more clearly in Fig. 3.
The opposite longitudinal ends of the top of table 1 are formed downwardly as at 4 and 5, respectively, and are nested Within the respective opposite extremities of the side walls 2, as indicated at 6, thus forming a neat and sturdy substantially rectangular base closed around .2,765,997 Patented Oct. 9, 1956 its four sides and thus providing an extremely rigid structure. At the juncture of the ends of the end Walls and the side Walls, as at 6, the said walls may be welded together by spot or line welding, as desired, for increased rigidity. l .y
The top or table 1 is provided with elongated slots 7 and 3, the slots 7 lbeing in alignment as are the slots 8, each pair' of slots being arranged along the opposite side walls 2, respectively, and at opposite ends of the table 1.
The second unit of the motor base illustrated in the embodiment shown comprises a slide B which includes a plate 9 of sufficiently shorter length than the length of the table 1 to permit the slide to be adjusted longitudinally within and beneath the table 1. The plate 9 is provided with depending side flanges 10 on opposite sides thereof and this inverted U-type construction is accommodated Within the base A for sliding movement therein, the flanges 11B having sliding engagement with the opposite side walls Z of the base, respectively, for free movement therealong, yet preventing lateral movement of the slide within the base A.
The slide B is provided with headed studs as indicated at 11 which project upwardly through the plate 9, the shanks of which are adapted to pass through the respective slots '7 and 8 and are threaded to receive nuts 12 and the washers 13 above the base 1 whereby the slide 9 may be locked in any longitudinal position with respect to the base 1 by tightening the nuts against the upper surface of the base 1 after the adjusting means which will be hereinafter described has been operated to position the slide at the desired adjustment with respect to the base 1.
As shown in Fig. 3, the legs 14 of a motor M are provided with laterally extending flange portions or feet 15 having openings whereby the motor may be secured to the base by having the threaded Shanks of the studs 11 pass through the openings in the lateral portions of the motor legs, the respective nuts and Washers being applied to the threaded Shanks above the lateral feet, as indicated in Fig. 3.
I have provided a simple and easily operated means adjusting the longitudinal position of the slide 9 with respect to the motor base, and this means may consist of a headed screw 16 passing through one of the end walls, such as 4, below the level of the base or table 1, and extending toward the opposite end wall 5 a sutiicient distance to accommodate full adjustment of the slide with respect to the base in either of its extreme limits oi' adjustability. The headed portion of the screw indicated at 17 lies of course outside the end wall 4 Where it may be engaged by a wrench or other tool for turning the screw to effect an adjustment of the slide. A washer 18 is provided on the opposite side of the end wall 4 and on the shank of the screw 16 and longitudinal movement of the screw 16 with respect to the base or table 1 of the motor base is prevented by the use of a Cotter pin 19 passing through a transverse opening in the headed end of the shank of the screw 16. This cotter pin may be removed in dismounting the slide from the motor base. The bottom face of the slide 9 is provided with a pair of slots 24B which lie substantially parallel to each other and transversely of the slide plate 9 and in spaced relation to each other, these slots being formed in the slide plate 9 near the forward end thereof, such as to the left in Fig. 2. A yoke which is substantially U- shaped in elevation is provided with a pair of depending arms 21 and a transverse portion 22, the arms 21 being adapted to pass through the openings 2i) from the upper side of the plate 9 to extend downwardly below the plate. These arms 21 are in alignment and are provided with aligned openings for receiving the screw 16, as indicated in Fig. 2. if desired, the portion of the plate 9 lying between the slots 20 may be upset in a downward position, as at 23 to provide an abutment for the side of a nut 24 which is threaded onto the shank in a position located between the depending arms 21. This upset portion provides a flat surface adjacent one of the Hats of the nut 24 whereby to prevent rotation of the nut with respect to the slide 9 but permitting rotation of the screw 16 through the nut by rotating the screw by means of a tool applied to the head 17 whereby to adjust the slide B in any one of a number of longitudinal positions within the limits of the slots 7 and 8.
By such construction, I have provided a floating adjustment mechanism for the slide which is effective to maintain the base and slide in proper alignment under all conditions in use by preventing binding action between the several parts.
From the above, it will be seen that the motor base slide embodying my invention is extremely sturdy and simple of construction and by virtue of the simplicity of the construction is very easy to assemble and disassemble in use. It will also be seen that I have provided an extremely simple and easily operated type of floating adjusting means for moving the slide longitudinally of the base in either direction.
Various Changes may be made in the details of construction and arrangement of parts of the invention without departing from the spirit thereof or the scope of the appended claims.
