Abstract

The base comprises a base plate having a plurality of slots formed therein, for receiving mounting bolts for machinery frames for mounting the machinery to the base plate, in which some of the slots have a greater width then the diameters of the shanks of the bolts used therewith. Accordingly, the wider slots restrain the bolts at only one side thereof against lateral movement. In addition, a strap coupled to an adjustment bolt is disposed below the slots being used, so that the machinery mounted thereabove can be displaced lengthwise along the base plate. The strap has threaded holes for engaging the machinery mounting bolts.

Base plates in the prior art are already known to have a plurality of slots so that differently-dimensioned machinery, having differently patterned mounting feet and variously-spaced fastening hardware can be used alternately on the same base plate. In this prior art it is arranged that these slots are formed in parallel, so that wider machinery frames can be fastened onto the same base plate which will also accommodate narrower machinery frames. The difficulty with this prior art arrangement arises from the fact that, in many circumstances, it is impossible to provision a sufficient number of parallel slots to accommodate many differentlydimensioned and similarly dimensioned machinery frames. That is, many machineryframes have mounting area dimensions with such small gradations therebetween, one from another, that there is not sufficient spacing to. provide metal between what would otherwise be adjacent, frame-accommodating slots.

To overcome this difficulty in the prior art, it has been the practice to affix separate fastening slide rails between the machinery and the base. plate. So also, obviously, it is a common practice to provide a separate base plate for each, differently-dimensioned item of machinery. Patently, these prior practices are expensive.

It is an object of this invention to set forth an improved base plate which avoids the prior art difficulties.

It is an object of this invention in particular to provide base means for fastener-mounting of machinery thereto, comprising a base plate; said base plate having means for receiving machinery-mounting fasteners, and wherein said fastener-receiving means includes at least a first plurality of means for restraining only one side of the machinery-mounting fasteners against lateral movement.

A feature of this invention comprises the provisioning of a base plate having a plurality of slots formed therein for receiving mounting bolts for machinery frames for mounting the'machinery to the base plate, in which some of the slots have a greater width than the diameters of the shanks of the bolts used therewith. Accordingly, the wider slots restrain the bolts at only one side thereof against lateral movement. In addition, a strap coupled to an adjustment bolt is disposed below the slots being used, so that the machinery mounted thereabove can be displaced lengthwise along the base plate. The strap has threaded holes for engaging the machinery mounting bolts. I

Further objects and features of this invention will become more apparent by reference to the following description taken in conjunction with the accompanying figures in which:

FIG. 1 is a plan view of the inventive base means, according to the invention; and

FIG. 2 is a side elevational view, partially in crosssection, of the base means of FIG. 1.

As shown in FIGS. 1 and 2, the base means comprises a base plate 12 having pluralities of

slots

14 and 16 which lie parallel with the plate longitudinal axis.

2 Slots 14 have a width which is complementary to the diameter of the shanks of fasteners normally to be used for the mounting of machinery. Slots 16, on the contrary, are wider, having a width in excess of that required for the diameter of the shank of fasteners used to mount machinery to the base plate. Such fasteners, as bolts 18 in penetration of a machine mounting frame (only a portion being shown), in FIG. 2, are received in a pair of slots 16. i

In FIG. 1 are set out several patterns of bolt shank diameters. For instance, there are shown four shank di-' ameter representations 22, illustrative of one pattern. Two of these diameters22 are shown disposed against the outer side of slots 16 on one side of the base plate 12, and the two other bore diameters 22 are shown disposed against the outer side of the other slots 16. Accordingly, machinery mounted to the base plate 12, with the bores in penetration of the'slots 16 is restrained against lateral movement, even though the slots are excessively wide. v

The shank diameter representations 24 through 28 illustrate the use of other patterns for mounting other machinery to the same base plate using the slots provided. In some of these, specifically diameters 26, it can be seen that the narrower slots 14 can be used in conjunction with the wider slots 16 for mounting machinery having a mounting frame dimension and bolt centers distances'which warrant fasteners set out in such a particular pattern. I I

The patterns represented by shank diameters 22 through 28 warrant the use of 4 slots, two toward one end of the base plate 12, and two inboard" thereof, because of the reach of mounting fasteners for certain types of machinery anticipated for mounting to plate 12. However, if other machinery is to be mounted, and the hold-down bolt centers distance does not require the use of four slots, a pair of juxtaposed slots works equally well, as illustrated by the patterns set out for

shank diameters

30 and 32. r

The base plate 12 comprises a pair of side walls 34 which suqport a deck 36. Beneath the deck 36 is a strap 38 which has a plurality of spaced-apart threaded holes 40 formed therein for receiving threaded shank portions of bolts 18. Strap 38 has a perpendicularly extending tab 42 which also has a threaded bore 44 for threadedly receiving an adjustment bolt 46. Bolt 46 has a drive head 48 which is restrained by a clip 50 supported on one end of the deck 36.

It is proposed that a pair of straps 38 and the associated bolt 46 and clip 50 can be used underneath the base plate l2for two purposes: for one, of the straps 38 receive and secure the mounting bolts, and serve the purpose of locking nuts. Additionally, if the machine mounted to the base plate 12 comprises a motor, or the like, having a pulley, or whatever, for receiving a drive belt (for driving or receiving drive from, associated machinery), bolt 46 and strap 38 provide means for ad justing the position of the machinery in order that the drive belt might be tensioned and slackened as -warranted.

While I have described my invention in connection with a specific embodiment thereof, it is to be clearly understood that this is done only by way of example and not as a limitation to the scope of my invention as set forth in the objects thereof and in the appended claims.
