3,027,140 JACK POSSTS AND MEANS FOR FORMING THE SAME Ralph H. Holzbach, Rte. 1, Freedom, Pa. Filed May 22, 1959, Ser. No. 815,108 6 Claims. (Cl. 254-88) This invention relates generally to improvement in jack posts, for all purpose use, and more particularly to means for forming such posts,
The primary object of the invention is to provide means for forming extensible jack posts out of body forming wood studs, or pipe sections, of any length, and by parts attachable thereto quickly and easily and which are detachable to form a kit from which component parts may be selectively used for attachment to such studs or pipe sections to form jack posts of different types, for instance light, medium, or heavy duty jack posts respectively.
Another object is to provide means for forming such posts adapted for arrangement into a compact readily portable kit for sale as such at a comparatively low cost.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is a perspective view of a jack post formed by means of this invention and out of a wood stud;
FIGURE 2 is an enlarged view in vertical longitudinal section of the same partly broken away;
FIGURE 3 is a perspective view of a heavy duty jack post formed by means of the invention out of a single pipe section;
' FIGURE 4 is an enlarged view in longitudinal section of the same partly broken away;
FIGURE 5 is a perspective view of a medium duty jack post formed by means of the invention out of pipe sections;
FIGURE 6 is an enlarged view in longitudinal section of the same partly broken away;
FIGURE 7 is a Perspective View of a light duty jack post formed by means of the invention out of pipe sections; and
FIGURE 8 is a view in longitudinal section of the same partly broken away,
FIGURE 9 is a fragmentary view in vertical section on an enlarged scale through an intermediate portion of the embodiment of FIGURE 6.
Referring to the drawings by numerals, the means of this invention comprises a head unit for a jack post and which is designated generally by the numeral 1, and best shown in FIGURE 4, and a foot unit designated generally by the numeral 3.
The head unit 1 comprises a jacking screw shaft 5 slidably fitting in and projecting upwardly out of a tubular sleeve 7 having a circular upper end flange thereon. A nut 11 on the shaft 5 seats on a washer 13 seating on the flange 9 and provides for extending'or retracting the shaft 5 upwardly and downwardly of the sleeve 7' to extend or contract the unit 1. A crown plate 15 seats on the screw shaft 5 and is detachably attached thereto by means of a nail, or the like, 17 extending through a center hole 18 in said plate 15 and into an axial bore 21 in the upper end of the screw shaft 5. The sleeve 7 is of the same diameter as a standard small size of pipe, for instance one-half inch in diameter. The sleeve 7 slidably and rernovably fits in a relatively shorter tubular adapter bushing 23 of a diameter corresponding to that of a size of pipe larger than the above mentioned one, for instance a 3,627,149 Patented Mar. 27, 1962 one and one-half inch pipe, and said bushing fits in a still larger size of pipe, for instance a pipe two inches in diameter.
A lock nut 25 is provided for threading onto a lower threaded end 27 of the sleeve 7 to retain the adapter bushing 23 on said sleeve. The bushing 23 has a lower threaded end 24 for a purpose presently seen.
The foot unit 3 comprises a foot plate 29 having a central opening 31 and adapted to receive an attaching nail 32, or a bolt 33 having secured thereto by a nut 35 an upwardly extending U-shaped, resilient and expanding leaf spring grip 37 all for a purpose presently apparent.
In forming a jack post out of a wood stud 41, as shown in FIGURES 1 and 2, and which forms the body of the post, the stud 41 is cut to the desired length and is provided with an axial bore 43 in its upper end which slidably receives the jacking screw shaft 5 with the washer 13 seated on the stud 41 and with the crown plate 15 attached to said shaft 5 and the nut 11 forming an adjusting nut and seating on the washer 13. T he foot plate 3 is detachably attached to the lower end of the stud 41 by the nail 32 frictionally fitted in an axial bore 34 in the stud. Thus the stud 41 is converted into an extensible and contractile jack post 39 with said stud forming an elongated body member of the jack post.
In forming a heavy duty jack post, such as shown at 45 in FIGURES 3 and 4, a desired length of pipe 47 of an internal diameter corresponding to the external diameter of the bushing 23 is cut to length and the entire head unit 1 utilized at the upper end of the pipe 47 with the bushing 23 slid into said upper end, the flange 9 of the sleeve 7 seating on said upper end and lock nut 25 threaded onto the lower end 24 of the sleeve 7 to retain the bushing 23 on said sleeve 7, the washer 13 seating loosely on the flange 9. The foot plate 29 is attached to the lower end of the pipe 47 by the spring grip 37 attached to the plate 29 and inserted upwardly into the lower end of the pipe 47 in friction gripping relation thereto.
To form a medium duty jack post, as shown at 49 in FIGURES S and 6, a pipe 51 of the same external diameter as that of the bushing 23 is cut to length and provided with an externally threaded upper end 53. The bushing 23 is then connected to the upper end 53 of the pipe 51 by a pipe coupling 55 threaded onto the lower end 24 of the bushing 23 and onto the upper end 53 of the pipe 51. With the sleeve 7 slid into the bushing 23 and the jacking screw shaft 5 inserted into the sleeve 7, the flange 9 of the sleeve 7 seats on the upper end of the bushing 23. The foot plate 29 is attached to the lower end of the pipe 51 as described with reference to FIG- URES 3 and 4.
In forming a light duty jack post, as shown at 57 in FIGURES 7 and 8, a pipe 59 of the same diameter as the sleeve '7 is cut to length and provided with an externally threaded upper end 61. The sleeve 7 is coupled to the upper end 61 of the pipe 59 by a pipe coupling 63 threaded onto the lower end 27 of the sleeve 7 and onto the upper end 61 of the pipe 59. The arrangement of the jacking screw shaft 5 in the sleeve 7 and of the washer 13, nut 11 and crown plate 15 is the same as described with reference to forming the heavy and medium duty jack posts 45, 49. The crown plate 15 may be provided with openings 65 for attachm nt by bolts, or nails, not shown, to an overhead structure, not shown.
As will now be seen, the described parts of the head unit 1 when detached from each other are adapted to form, together with the foot unit 3 a kit of readily replaceable parts, for sale as a kit, and which parts, or the entire kit may be selected for use for forming jack posts such as described in the foregoing.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
