United States Patent RADIATOR RAISING AND TRANSPORTING JACKS Lewis C. Van Hnben, Orangeburg, N. Y.
Application August 5, 1955, Serial No. 526,692
2 Claims. (Cl. 214 650) My invention relates to improvements in jacks of the type adapted for using inpairs at opposite ends of steam or hot water radiators for transporting purposes.
The primary object of my invention is to provide a telescopically extensible and contract-able jack for the above purposes having lever means for extending the same with a minimum of effort by an operator and means for locking the lever to lock the jack extended.
Another object is to provide in such a jack easily applied fasteners for attaching the jack at the end of high or low radiators.
Still another object is to provide a jack having the above advantages and which is simple in construction and strong, while light in weight, and comparatively inexpensive to manufacture and safe to use.
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 view in side elevation of a pair of my improved jacks attached to a radiator and extended;
Figure 2 is an enlarged view in front elevation of one of the jacks contracted and partly broken away and shown in section;
Figure 3 is a view in vertical section taken on the line 3-3 of Figure 2;
Figure 4 is a similar view showing the jack contracted;
Figure 5 is an enlarged, fragmentary exploded view in side elevation of parts of one of the fasteners;
Figure 6 is an enlarged view in perspective of means for attaching the fasteners to the jack; and
Figure 7 is an enlarged fragmentary view in horizontal section taken on the line 7-7 of Figure 4.
Referring to the drawings by numerals, 1 designates a radiator having a pair of my improved jacks 3, 5 applied thereto at the ends thereof. The jacks 3, 5 being duplicates with the exception presently noted, a description of one will sufiice for both.
The jack 3 comprises a wheeled frame 4 of inverted U-shape having a pair of tubular standards 7 connected together adjacent lower ends thereof side by side and parallel by a tubular cross member 9. The standards '7 and member 9 are formed of standard piping and welding, not shown, connect the standards 7 to member 9. Horizontal foot plates 11 are suitably secured to the lower ends of the standards 7 and are supported by wheel forks 13 having small wheels 15 mounted therein. The foot plates 11 and wheel forks 13 are offset outwardly and to one side of the standards 7 for stabilizing purposes and bracing gusset plates 16 connect the standards 7 at the outer sides thereof to the foot plates and are suitably secured thereto. The wheels 15 of the jack 3 are castor wheels for steering purposes, whereas, the wheels of the jack 5 run in planes transverse to the plane of the jack 5 preferably.
2,784,860 Patented Mar. 12, 1957 A jacking frame 17 vertically slidable on the wheeled frame 4 comprises a pair of elongated tubular slides 19 of piping slidably fitted on the standards '7 and connected together by an upper cross cleat 21, a. lower cross cleat 23 and a central cross cleat 25, each suitably attached to said slides 19 as by welding 27. The cleats 21, 23, 25 are at the front of the jack 3 and extend outwardly beyond the slides 19 and are provided outwardly of said slides with vertical slots 29 therein for a purpose presently seen. The ends of the lower cleat 23 are twisted forwardly, the purpose of which will presently appear.
A pair of fasteners 31, 33 are provided for attaching the jacking frame 17 to one end of the radiator 1 with the cleats 21, 23, 25 facing said end. The fasteners 31, 33 each comprise a short link chain 35 for engaging a selected link at one end in the slot 29 in one end of one of .the cleats 21,23, 25 and having a bolt 37 with a washer 39 and wing nut 41 on its other end for attaching in the slot 29 in the other end of the cleat and tightening the chain. A similar pair of fasteners 32, 34 is provided for the jack 5.
Lever means is provided for raising the jacking frame 17 to extend the jack 3 comprising a hand lever 43 in the rear of the jack and which is pivoted above the jacking frame 17 for vertical rocking movement transversely of the jack on a cross shaft 45 retained by end nuts 47 in a pair of lateral rearwardly extending ears 49 on the standards 7. Bushings 51 on the shaft 45 between the ears 49 and opposite sides of the lever 43 act to center said lever relative to said jack. The lever 43 is provided with a short lever arm 53 operatively connected to the jacking frame 17. The operating connection comprises a pair of links 55 depending from opposite sides of the lever arm 53 and pivoted at upper ends thereto, as at 57, with lower ends pivoted, as at 59, to a lateral rear lug 61 on the upper cleat 21.
Referring now to the operation, the jacking frame 17 normally slides downwardly on thestandards 7 onto the member 9 by gravity to contract the jack 3, as shown in Figures 2 and 3, thereby pivoting the lever 43 into upswung position. To extend the jack 3, the lever 43 is swung downwardly against the lug 61 parallel with the jacking frame 17 as best shown in Figure 4. This causes the short lever arm 53 to swing upwardly to lift the links 55 and hence the jacking frame 17 on the standards 7.
The locking means for the lever comprises a locking pin 63 attached by a chain 65 to the lug 61, a pin receiving hole 67 in the lever 43 on the opposite side of the shaft 45 from the pivot 57, and a pair of opposite pin receiving holes 69 in the links 55. When the lever 43 engages the lug 61 which thereby establishes the down swung position of said lever and the extended position of the jack, the hole 67 aligns with the holes 69 and the locking pin is inserted through said holes to lock the lever 43 down and to the links 55 all as best shown in Figures 5 and 7.
The pair of jacks 3, 5 are applied to the opposite ends of the radiator 1 while contracted, and against said ends and facing the same in the following manner. The pair of fasteners 31, 33 for the jack 3 are attached to the ends of the upper and lower cleats 21, 23 in the manner already described with the upper fastener 31 looped through the upper portion of the radiator adjacent one end thereof and the lower fastener 33 looped around the lower end of one coil adjacent said end. The fasteners 32, 34 for the jack 5 are similarly applied to the jack 5 and to the radiator 1.
If the radiator 1 is of the low type, the upper fasteners 31, 32 are applied to the intermediate cleats. After the fasteners 31, 33, 32, 34 are applied the jacks are extended in the manner described to lift the radiator 1 at 3 opposite ends thereof for transporting on the jacks if desired.
The foregoing is considered as illustrative only of the principles of the invention, Further, 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 and operation 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:
1. A jack for lifting a radiator comprising an inverted U-shapedframe including a pair of vertical standards, a cross member connecting the lower edge thereof, a jacking frame vertically slidable on said standards and normally resting on said cross member, a lever for lifting said jacking frame, means pivotally mounting said lever on said U-shaped frame above said jacking frame for downward swinging to lift the jacking frame, means operatively connecting the lever to the jacking frame, cross cleats on the jacking frame, and flexible fasteners adapted to be looped around coils of the radiator and attachable to said cleats for securing said lifting frame to the radiator, said second named means comprising a pair of opposite links pivoted at one end to said lever, and a lug on one of said cleats to which the other ends of said cleats are pivoted, and locking means for said lever, comprising a locking pin, said lever and links having apertures therein aligned in the downswung position of said lever for insertion of said pin therethrough.
2. The combination of claim 1, said lug limiting downward swinging of said lever to align said apertures.
