Description

A- ROSEKRANS PIPE SLEEVE HOLDER Filed Aug 28l 1962 Jam 2s, 1965 FIG 3 United States Patent O 3,167,310 PEPE SLEEVE HOLDER Alvie Roselrrans, 71 Ohio Ave., Elmira, NX. Filed Aug. 28, 1962, Ser. No. 220,090 Claims. (Cl. 269-52) The present invention relates to .a pipe sleeve holder and more particularly to a device for yaccurately positioning and rigidly holding a pipe sleeve or the like within a form or enclosure into which concrete or other cementitious material is to be poured.
In the construction of foundations, walls, ceilings and so forth of concrete or the like, it iscommonly required that various tubular members such as pipe sleeves be located within the forms or enclosures into which the material is to be poured, the positions and attitudes or orientation of said pipe sleeves being specified in the plans for the building.
One prolific use of such pipe sleeves is in the construction of concrete footings for cyclone `fences or the like where the sleeves, as located in said footing walls are spaced rand alincd to receive the metal 4posts of the fence when it is erected. Other numerous uses are for the purpose of locating and supporting both temporary and premanent stanchions, posts and so forth for supporting guard rails, along walkways, docks, etc. However, heretofore, there has been no satisfactory device commercially available for holding such pipe sleeve in the desired positions, reliance being usually had merely on the skill o-f the workmen to devise improvised holding means of various kinds for that purpose.
It is an object of the present invention to provide a pipe sleeve holder for the above purpose which is convenient in application, efficient in operation, and simple and economical in construction.
It is another object to provide such 'a device which is adaptable for use with pipe sleeves of various diameters and contours.
It is another object to provide such a device which is readily removable from the pipe sleeve after the cementitious material around the pipe sleeve has hardened, whereby the device is made available for repeated utilization.
Further objects and advantages will be apparent from the following description taken in connection with the accompanying drawing, in which:
FIG. l is a side elevation of the device shown as located in a pipe sleeve which has been embedded in a section of a concrete wall, the device being illustrated in released position for the sake of clarity;
FIG. 2`is a top plan View of the yoke member to which the gripping blades of the device are linked; and
FIG. 3 is `a top plan view of the plate member used for positioning and orienting the device with respect to the walls of the form in which the cementi-tious material is to be cast.
In FIG. 1 of the drawing there is illustrated a spindle 1 which `is threaded for a major portion of its length and which has a yoke member 2 slidably mounted thereon. A plural-ity of tapered blade members 3 are linked at one end to the yoke member 2 las by means of links 4 pivotally connected to the blades as indicated at 5 and to the yoke as shown at 6, whereby said blades are tree for unrestricted radial movement while being rigidly connected to the yoke in respect to axial and rotational movement.
Although the yoke 2 has been illustrated as having four arms for connection with four blades 3, it will be understood that a greater or lesser member of such arms and blades may be utilized, although a minimum of three has been found desirable `for the intended purpose.
Means on the lower end of the spindle 1 is provided for "ice expanding the blade members 3 into gripping engagement with the interior `surface of the tubular member or pipe sleeve 7 which itis intended to locate prior to and during the pouring operation of the concrete wall or the like. As here shown, this expanding member is in the form of a disc 8 which is rigidly mounted in any suitable manner on the lower end of the spindle 1 and which is provided with peripheral grooves 9 for slidably receiving and guiding the blades 3, the bottoms of said grooves 9 being preferably tapered as shown at 10 to conform to the inner tapered edges of the blades 3.
In order to actuate the blade expanding disc 8, a nut 11 is threaded on the upper portion of the spindle 1 above the yoke member 2 whereby threading the nut member 11 down on the spindle 1 will draw the expanding disc 8 upwardly relative to said yoke to thereby move the blades 3 outward `into gripping engagement with the interior surface of the pipe sleeve 7.
Means are provided for positioning and orienting the assembly of the holding device with the pipe sleeve mounted thereon, here shown in the form of a at plate member 12 having a centrally located notch 13 for receiving the spindle 1, said plate being adapted to be clamped by the nut l1 against the yoke member 2, a washer 14 being preferably interposed between the inut l1 and positioning plate 12. Said positioning plate is provided with a plurality of apertures 15 spaced throughout its length for the reception of any suitable means such as indicated at 16 for attaching said plate to the walls of the form or enclosure in such manner as to properly position the pipe sleeve 7 in the structure to be poured.
lIn the operation of the device, the plate =12 `is assembled on the spindle -1 beneath the nut 111, the device is inserted in the pipe sleeve 7, and the nut 1-1 is then tightened to simultaneously expand the blades 3 into gripping engagement with the interior surface of the pipe sleeve, and at the same time clamping plate 1.2 against the top of the yoke member 2. It will be appreciated that during this step in the operation of the device, the free radial movement of the blades 3 as permitted by the link connections 4, 5, 6 lwill enable the blades to align themselves against the inner surface of the sleeve and thereby prevent any possible dellection of the sleeve `from its proper relation to the positioning plate 12 during the pouring operation. The assembly is then placed on or against the walls ofthe enclosure or form into which the concrete or the like is to .be poured, and attached thereto in such relation as t0 accurately locate the pipe sleeve 7 in its intended position and attitude. The pipe sleeve is thereby so held duringv the pouring operation and until `the cementitious material is hardened so that the pipe sleeve is embedded and iixedly positioned therein in the desired location.
-After the structure has hardened, it is merely necessary to unscrew the nut 11 in order to permit the blades 3 to release their gripping engagement on the pipe sleeve 7 as illustrated in FIG. -1, after which the device may be readily removed ifor yfurther utilization The release of the blades 3, and their subsequent insertion into another pipe sleeve for further use is Ifacilitated by retractile springs 17, 18 located near the free ends of said blades and maintaining them at all times fully engaged in the grooves `9 in the expanding disc 8.
It will be understood that in certain types of construction, the .plate member 2 may in itself constitute a wall of the enclosure to be iilled with .cementitious material, and it is intended that such contemplated use of this element of the combination be within the .purview of the disclosed invention. -Although certain structure has been shown and described in detail, Iit will be understood that changes may be made in the precise `form and dimensions of the parts without departing from the spirit of the invention.
