[57] ABSTRACT An apparatus for selectively mounting fluid motor pressure cylinders on supporting surfaces in at least three different ways. The apparatus comprises at least two novel mounting brackets each of which includes a support flange and a leg flange extending at right angles from one edge of the support flange. Four brackets are secured in pairs to both ends of the cylinder and extend laterally of the cylinder for the foot mounting position. A pair of brackets is secured along a common axis at one end of the cylinder and also extends laterally of the cylinder for the pivot mounting position. The head flange mounting position allows the cylinders to be mounted in a cantilevered position from one end thereof and utilizes two brackets secured along a common axis at one end of the cylinder and extending longitudinally of the cylinder. In the latter position, an end portion of the cylinder is received and secured in recesses formed in the leg flanges whereby two cylinder support points are provided and spaced a predetermined distance apart.

17 Claims, 7 Drawing Figures COMMU/V SECUR/IVG Am 50 PAIEME JAN] 51914 SHEET 2 0F 2 COMMON SECUK/A G FLUID MOTOR PRESSURE CYLINDER MOUNTING APPARATUS This invention relates to a fluid motor cylinder mounting apparatus and, more particularly, to a bracket which may be used on pneumatic and hydraulic pressure cylinders and the like which is susceptible of mounting such cylinders on a supporting surface or surfaces in at least three different ways.

BACKGROUND OF THE INVENTION In the past, many types of apparatuses have been used for mounting fluid motor cylinders including hydraulic and pneumatic pressure cylinders and the like, on supporting surfaces. These apparatuses have included brackets having legs and other similar appliances which could be used to mount a fluid motor cylinder in one position on a supporting surface. However, the prior brackets were not adaptable for mounting cylinders in many varied positions, and required the substitution of another type bracket when the mounting position required a change. Especially when a particular application required the mounting of a fluid motor cylinder on its end or in a cantilevered position from a supporting surface, the prior brackets had to be replaced with heavier, bulkier, more rigid supports which could withstand the forces imposed by the cantilevered or end mounting. The substitution of these other brackets not only required time, but also generally required a great deal more space due to their requisite increase in strength and rigidity and, thus, the bulk of the mounting bracket. Consequently, the prior known fluid motor cylinder mounting brackets were not economical and required frequent substitution of other brackets for the accommodation of several varied mounting positions.

Therefore, there was no available fluid motor cylinder mounting apparatus which could be utilized to accommodate several different cylinder mountings from only one apparatus mounting position which would be strong and rigid enough to support a fluid motor cylinder. in a cantilevered or end type mounting, which would consume only a small amount of space for a mounting of that type, and which would be easily convertible from one type of mounting to another.

SUMMARY OF THE INVENTION Accordingly, it is an object and feature of the present invention to provide a fluid motor cylinder mounting apparatus which is versatile for mounting a fluid motor cylinder in any one of several different ways.

It is another object and feature of the present invention to provide a fluid motor cylinder mounting apparatus which is versatile for several different mountings while using only one securing means which is secured to the cylinder at the same place for each mounting.

It is a further object and feature of the present invention to provide a fluid motor cylinder mounting apparatus which is simply constructed, strong and durable, and yet which requires little more space than the fluid motor cylinder which it supports.

These and other objects and features of the present invention may be accomplished by providing an apparatus for mounting a fluid pressure cylinder on at least one supporting surface which apparatus includes the use of at least two brackets of a novel and inventive design. The novel brackets comprise a support flange and a leg flange extending at right angles from one edge of the support flange with both flanges each including at least one aperture for receiving securing means therethrough. The support flange is greater in length than the leg flange. A recess is formed in a free edge of the extending leg flange, the recess being shaped to correspond to at least one end of the cylinder. The brackets are secured to at least one end of a fluid motor pressure cylinder at a distance less than the radius of the cylinder from the end of the cylinder by securing means or bolts extending along a common axis which runs through the cylinder.

When it is desired to mount the cylinder in the cantilevered or end position, the brackets are mounted on the cylinder with the leg flanges extending inwardly towards one another, and the support flanges extending longitudinally such that at least a portion of the cylinder end is received in the recesses. The cylinder end is also threaded and includes a nut which is then tightened against the leg flanges. The entire cylinder and brackets is mounted on a supporting surface by means of securing means secured through the apertures in the leg flanges. The result is a rigid space-saving cantilevered or end-type mounting which rigidly supports the fluid pressure cylinder from two points spaced along the longitudinal axis of the cylinder.

Other mountings are possible using the same brackets secured at the same positions by pivoting the brackets such that the support flanges extend laterally of the longitudinal axis of the cylinder and either pivotally supporting one end of the cylinder on two of the brackets or rigidly supporting both ends of the cylinder on four of the brackets. In either of the latter two mounting positions, the right angled leg flanges may be turned outwardly away from one another or inwardly towards one another.

These and other objects, advantages and features of the invention will become apparent from a study of the following description taken in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the drawings, FIGS. 1 and 2 show a bracket means or mounting bracket forming one embodiment of the present invention. Generally, at least two of the mounting brackets 10 will be used together to support a fluid motor pressure cylinder thereon in one of several different mounting positions or mountings. As will be described more fully below, FIGS. 3 through 7 reveal the several mounting positions or mountings available with the single type of mounting bracket 10.

The bracket means or mounting bracket 10 basically comprises a support flange or longer leg 12 and a leg flange or shorter leg 14 extending at a right angle from one edge of the support flange 12. The support flange 12 is generally triangular in shape, has a length X (FIG. 1) greater than the radius R (FIG. 3) of the cylinder to be supported, and includes an aperture 16 formed generally adjacent to the apex 18 of one of the angled corners of the body 12. The length X is greater than the radius in order to allow the cylinder to be supported away from the supporting surface when brackets 10 extend laterally of the cylinder. The leg flange 14 is formed to extend perpendicularly from the plane of the support flange 12 from the edge 20 of the flange. The edge 20 is directly opposite the apex 18. The aperture 16 is bored generally adjacent to this same apex 18 a predetermined distance A" (FIGS. 1, 6, and 7) from he shorter leg or leg flange 14.

The leg flange 14 is generally rectangular in shape, has a length L" less than the radius R of the cylinder to be supported thereby, and extends at right angles from the full length of the edge 20 opposite apex 18. Also, the width W of leg flange or shorter leg 14 is greater than its length L (FIG. 2). Flange 14 includes apertures 22 bored therethrough for receiving securing means for securing both the bracket 10 and a fluid motor cylinder secured to the bracket to a supporting surface. Additionally, leg flange 14 includes a recess 24 formed in an extremity of leg 14 and corresponding to the shape of an end means included on the end of a fluid motor pressure cylinder supported by bracket 10. The extremity of leg 14 in which recess 24 is formed is, in the preferred embodiment, the edge of leg 14 which is directly opposite the edge of which leg 14 is joined at right angles to leg 12. In the preferred embodiment of the mounting bracket 10 shown in FIGS. 1 and 2, the recess 24 will have a width Z (FIG. 2) greater than the length L of leg 14 but less than twice L and will have the shape of a partial circle adapted to correspond to the circular shape of a threaded end member extending from an extreme end of fluid motor pressure cylin der of the type normally supported by bracket 10. The size relationship of L, R, and Z, as described above, allows a sufficient amount of a portion ofa cylinder to be received in recesses 24 to insure a secure mounting, while preventing legs 14 from extending past the center line or axis of the cylinder when the brackets are secured to the circumference thereof, as shown in FIG. 5. Recess 24 may, of course, be formed in many other shapes without deviating from the spirit of the invention.

The bracket means or mounting bracket 10, described above, may be used in its one preferred form to selectively mount a fluid motor pressure cylinder in at least three different mounting positions, as will be described hereinafter in reference to FIGS. 3 through 7. All of the several different mounting positions may be obtained by securing the mounting bracket 10 to the fluid motor pressure cylinder at the same point on the end of the cylinder and thereafter pivoting the bracket into different positions, which positions allow the several different mountings described below.

Referring now to FIGS. 3 through 5, a fluid motor pressure cylinder 30 is shown supported by at least two of the brackets 10. FIG. 3 depicts two of the three available mounting positions obtainable with mounting bracket 10, the two mountings comprising both the pivot and foot mounting positions. As shown therein, fluid motor pressure cylinder 30 includes a body portion 32 having a diameter D and a radius R which terminates in an end means 34 and 36. Cylinder 30 further includes a rod 38 which is moved by a piston (not shown) mounted within the cylinder 30 and powered by compressed air, hydraulic fluid or oil admitted selectively on either side thereof, thereby resulting in reciprocal movement of the rod 38. End means 34 and 36 include

cylindrical extension members

40 and 42 formed coaxially with the axis of cylinder 30.

Extension members

40 and 42 are circular in cross section and threaded in order to receive a head securing means or

nuts

44 and 46, respectively. In the particular mounting position shown in FIG. 3, however, head securing means or

nuts

44 and 46 are not used.

Referring again to FIG. 3, the foot mounting position will be understood. As shown therein, four of the bracket means or mounting brackets 10 are used with the fluid motor pressure cylinder 30 to form this particular mounting position. Two of the brackets 10 are mounted on each end of the cylinder 30 by means of securing means or bolts 48 which are secured in threaded holes bored in end means 34 and 36 along a common axis from opposite sides of the cylinder. In the preferred embodiment, the common axis forms a diameter of the cylinder. However, the axis may also be formed such that it is parallel to a diameter of the cylinder and is offset therefrom (not shown). Thus, in the latter case, the longer leg 12 will have a sufficient length to extend beyond the circumference of the cylinder from the point at which it is secured on or adjacent to the cylinder. The bolts 48 are thus received in apertures 16 in brackets 10 and are coaxial with one another at each end of the cylinder 30. The foot mounting thus comprises four of the brackets 10, two of which are mounted at each end of the cylinder 30, which brackets are used to rigidly secure and support the cylinder 30 to a supporting surface by means of securing means fastened to the supporting surface through apertures 22 in leg flanges 14.

FIG. 3 also illustrates the pivot mounting position for the cylinder 30. The pivot mounting position includes the use of two of the brackets 10 secured to either side of the cylinder 30 in end means 34. Preferably, the pivot mounting is used with the closed end of a single ended cylinder, such as cylinder 30, since rod 38 will be reciprocating out of the opposite end and the pivot mounting at the closed end will obviate any interference with such reciprocating action. However, both the pivot and foot mountings may be used with either single or double-ended cylinders.

The brackets 10 are secured along a common axis through cylinder 30 by bolts 48 passed through apertures l6 and secured in threaded holes bored along the common axis in end means 34. As described above, the common axis may be either a diameter of the cylinder or parallel to and offset from a diameter thereof. The brackets 10 may then be secured by any convenient securing means through apertures 22 to a supporting surface.

The brackets 10 thus support the cylinder 30 along a common axis which passes through end means 34 in the preferred embodiment, and allow the cylinder 30 to pivot about that axis as the rod 38 is extended or withdrawn. The pivot mounting is useful in installations such as door closures and others wherein it is necessary for the cylinder 30 to pivot as the rod 38 is extended and withdrawn. The pivot mounting thus utilizes only two brackets 10 mounted coaxially with bolts 48 and one end means 34 and does not utilize the fluid and fourth brackets used in the foot mounting position, also illustrated by FIG. 3.

The brackets 10, when utilized with either the foot mounting or pivot mounting for cylinder 30, may be secured to cylinder 30 with the leg flanges 14 extending outwardly away from one another along the supporting surface, as shown in FIG. 4, or inwardly towards one another as shown in FIG. 5. The mounting of the brackets 10 with the leg flanges 14 extending outwardly as shown in FIG. 4 provides a somewhat greater amount of stability for the cylinder 30 when mounted in such a fashion. However, the mounting of the brackets 10 with the leg flanges 14 extending inwardly as shown in FIG. 5, provides nearly as great an amount of stability, while limiting the space utilized to mount the cylinder 30 to that of the cylinder 30 itself.

Referring now to FIGS. 6 and 7, the third or head flange mounting position will be described in greater detail. As shown in FIG. 6, a cylinder 50 includes an end means 52 mounted on cylinder body 53. End means 52 includes a cylindrical extension member 54 which extends coaxially from the body 53 of cylinder 50 and is threaded to receive head securing means or nut 44. The cylinder 50 is similar to cylinder 30 in most respects except that it is double-ended and allows the rod 56 to be extended and with-drawn from both ends of cylinder 50 by means of a piston (not shown) mounted therein. As explained above, cylinder 30 is single-ended and allows the rod 38 to be extended and withdrawn from only one end of cylinder 30.

As shown in FIG. 7, the end means 52 comprises an end fitting 58 which includes the threaded cylindrical extension member 54. End fitting 58 includes a central bore 60 which allows the reciprocating rod 56 to pass therethrough. The central bore 60 is closed at the outer end by a threaded plug 62 and a sealing or packing ring 64 both of which are received in the outer end of threaded cylindrical extension member 54. With the double ended cylinder 50, both end fittings are similar to that described above.

The head flange mounting includes the use of two of the brackets 10 secured at either end of the cylinder 50. Brackets 10 are secured by means of bolts or securing means 48 which are received in apertures 16 of brackets 10 and threaded

holes

66 and 68 bored along a common axis, which, in the preferred embodiment, pass through end fitting 58. The brackets 10 are mounted or secured to the end fitting 58 with the support flanges extending longitudinally of the cylinder axis such that they extend beyond the end of the cylinder of end fitting, the leg flanges 14 extending inwardly towards one another, and the recesses 24 contacting the end of threaded extension member 54. When the brackets 10 are in this position, as shown in FIG. 7, the nut 44 may be threaded tightly against both the leg flanges 14 thereby rigidly securing the flanges 14 against the nut 44 and the end of the threaded extension member 54 at least partially received within recesses 24. The cylinder 50 may then be mounted to a supporting surface s, shown by the phantom lines in FIGS. 6 and 7, by means of the head flange mounting including the two brackets 10 secured to the end means 52 of cylinder 50 as described above.

As described above with the other type mountings, the common axis along which holes 66 and 68 are bored is, in the preferred embodiment, a diameter of the cylinder passing through the end means. In this embodiment, recesses 24 are formed centrally in the extremity of leg 14 (see FIGS. 6 and 7). However, the common axis may also be parallel to a diameter and offset a distance from that diameter (not shown). In this latter case, the recesses are offset an equivalent distance from the centers of the extremities in which they are formed. Thus, in this latter case, the recesses 24 will properly engage or receive member 54 even though the brackets are secured to the end means of the cylinder a distance offset from a diameter thereof. Further, in both of these embodiments, the distance B (FIGS. 6 and 7), Le, the distance from the edge of end fitting 58 to the common securing axis, at which the common axis is spaced back from the end of the cylinder (not the end of member 54) is less than the radius of the cylinder. Distance A represents the distance between the spaced support or contact points of bracket 10 with member 54 and end fitting 58, as described below. The spacing of distance B allows the brackets 10 to be pivoted between all of the mounting positions without encountering the edges of the cylinder.

The brackets 10 thus support the cylinder 50 by means of two spaced contact points; the first at the end of cylindrical threaded extension 54 and the second at bolts 48 received in

holes

66 and 68 and end fitting 58, which contact points are separated by the distance A as shown in FIGS. 6 and 7. This distance corresponds to the distance between leg 14 and aperture 16 as mentioned above. The contact points thus provide sufficiently spaced support points for securely and rigidly mounting the cylinder 50 in either a cantilevered, horizontal position from a vertical wall, or in a vertical end position from a horizontal supporting surface. The distance A may be varied in proportion to the different sizes of cylinders to be supported. Thus, the distance A will be longer for a longer cylinder and vice versa. Such variation may be accomplished, fbr example, by increasing the length of member 54 and brackets 10, without altering the position at which the brackets are secured to the cylinder. In any event, the distance A may be predetermined to adequately and sufficiently support various fluid pressure cylinders.

When the double-ended cylinder 50 is utilized at the head flange mounting described above, a hole h must be provided in the supporting surface s to allow the reciprocation of rod 56 as shown in FIGS. 6 and 7. However, it will also be apparent that the head flange mounting may be used on a single-ended cylinder of the type shown as cylinder 30 in FIG. 3, wherein the plug 62 is replaced with a closed plug and the rod is reciprocated out of the end opposite that with which the cylinder is mounted on a supporting surface. Thus, no aperture h need be provided in a supporting surface when the closed end of a single-ended cylinder 30 is utilized to mount the cylinder 30 on a supporting surface by means of the head flange mounting of the type shown in FIGS. 6 and 7.

The use of the bracket means or mounting bracket 10 to support either the single-ended cylinder 30 or the double-ended cylinder 50 in the at least three separate mounting positions, namely, the foot mounting, pivot mounting, the head flange mounting positions will now be understood.

The foot mounting for the

cylinder

30 or 50 is obtained by mounting four of the brackets 10 such that the legs 12 extend laterally of the cylinder with securing means or bolts 48 received through apertures 16 in each of the brackets 10 and threaded holes formed in the end means or

fittings

34, 36 or 52 of the cylinders. The bolts 48 are secured along a common axis on opposite sides of the cylinder such that the cylinders in the preferred embodiment, will be supported horizontally with the supporting surface by means of the brackets 10. The brackets 10 are in turn secured to the supporting surface by any convenient securing means received through apertures 22 in leg flanges 14. As shown in FIGS. 4 and 5, the leg flanges 14 may be disposed such that they extend inwardly towards one another or outwardly away from one another.

The pivot mounting is also shown in FIG. 3 and is a variation of the foot mounting. The pivot mounting comprises securing two of the brackets 10 with the support flanges extending laterally of the cylinder at one end of cylinder 30 by means of bolts 48 received in threaded holes formed in the end means 34 along a common axis therethrough. The common axis may be either a diameter of the cylinder or offset from and parallel to such a diameter. The brackets 10 are in turn secured to a supporting surface with securing means received through apertures 22 and support the end means 34 of cylinder 30 pivotally along the axis of bolts 48, which axis lies horizontal to the supporting surface in the embodiment shown in FIG. 3. The cylinder may thus pivot about the common axis of bolts 48 as the rod 38 is extended and withdrawn by means of the piston within the body 32 of cylinder 30.

Finally, the head flange mounting, shown in FIGS. 6 and 7, is obtained by using the same brackets 10 utilized with both the foot and pivot mountings described above by securing the brackets 10 to the end means of either

cylinder

30 or 50 with the leg flanges 14 extending inwardly toward one another and the support flanges or legs 12 extending longitudinally of the cylinder. The brackets 10 are disposed on the end means such that the recesses 24 in the leg flanges 14 receive at least a portion of the cylindrical threaded extension member 54 therein. The head securing means or nut 44 is then tightened against the flanges 14 to secure the brackets in the head mounting position. The brackets secured in this position may then be used to mount the

cylinder

30 or 50 in a cantilevered position on a vertical wall or on the end of the cylinder on a horizontal supporting surface. The

cylinder

30 or 50 is thus supported by two contacting points spaced apart by the distance A, shown in FIGS. 6 and 7, one comprising the end of cylindrical extension member 54 and the other comprising the bolts 48 lying along the common axis through end means or

fittings

34, 36, or 52, which axis is parallel to the supporting surface in the preferred embodiment. This distance A is predetermined and proportional to the size of the cylinder to be supported.

It will thus be understood that the brackets 10 provide a simply designed and constructed fluid motor pressure cylinder mounting apparatus which may be secured in pairs to either end of a singleor

doubleended pressure cylinder

30 or 50 in at least three different mounting positions. The present, novel apparatus thus results in an economical bracket construction which is both strong enough and rigid enough to support the fluid cylinder horizontally with the supporting surface in the foot mounting position, pivotally with respect to the supporting surface in the pivot mounting position, and vertically or horizontally from one end of the cylinder in the cantilevered or end mounting position with the head flange mounting.
