JAMES ROBINSON, v W jw Patented Nov. 3%), 1926.
UNI ED S TES J'AMES ROBINSON, OF DAIREN, MANGHURIA.
Application filed July 10 My invention relates to improvements in wrenches, for assembling and disassembling direct radiators, connected with right-and left-hand threaded nipples.
an important object of the invention is to provide a wrench ot the above mentioned character, which may be used in connection with nipples 0t diflerent sizes, such as one and one-halt inch and two inch nipples.
A further object of the invention is to provide a wrench of the above mentioned character, which may be used in connection with radiator sections of different lengths.
The radiator wrench, now employed for assembling and disassembling direct radiators, is obtainable in different sizes, depending upon the size of the nipple, such as a one and one-half inch nipple or a two inch nipple. These wrenches are provided at one end only with a head which engages with the flange within the nipple. These wrenches also come in dilterent lengths, depending upon the lengths of the radiator sections, to be assembled and disassembled.
In accordance with my invention, I provide a wrench embodying a bar which is provided at its opposite ends with heads of differentsizes, for engagement' within nipples or different sizes, such as one and one-half inch and two inch nipples. Fur ther, the bar is provided withl a turning member or head, longitudinally adjustable thereon, whereby the wrench may be made in the maximum length, and the turning head adjusted longitudinally thereon, as may be found desirable for use in connection with radiator sections of varying len ths.
y wrench thus dispenses with the necessity of employing a plurality of wrenches of different sizes and lengths, and is also a great time and labor saver.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate, like parts throughout the same,
Figure 1 is a plan view of a wrench em bodving my invention,
Figure 2 is a side elevation of the bar element included in the wrench,
Figure 3 is a side elevation of the device in use,
Figure 4 is a transverse section taken on line l.--l: of Figure 1,
Figure 5 is a transverse section on line 55 of Figure 3, and,
1925. Serial No. 42,702.
Figure 6 is a perspective view of a liner.
In the drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 dcsignates a relatively long bar, which is made in a length for use with the rat iator section having the maximum length, whereby the wrench may he used with radiator sections of shorter lengths. This bar is provided at one end with a nipple turning head 11, and at its opposite end with a nipple turning head 12. These nipple turning heads are oi different sizes. The head 11 may be adapted for properly engaging within a one and one-half inch nipple while the head 12 may suitably engage in a two inch nipple. As clearly shown in Figure 5, the head may engage with flanges or projections 13, formed in the nipple 1a, which is a rightainl-lefi-hand threaded nipple. As is well known, direct radiators are formed in sec tions of selected lengths, and these sections are connected by the direct right-and-leit hand threaded nipples.
The bar 10 is provided with grooves 15, extending longitudinally throughout the same for the major portion of its length.
The numeral 16 designates a turning head embodying a sleeve 17. This sleeve has a recess for the reception of liners 18. These liners have segmental flanges 19, held within recesses 20 whereby the liners are positively locked against turning movement with respect to the sleeve 17. The liners are held against longitudinal displacement by set screws 21'. The liners 18 are provided upon their inner eurv d sides with flanges or ribs 21, slid-able within the grooves 15. In view of the foregoing description, it will be seen that the sleeve 17 is splined upon the rod, and is free to be shifted longitudinally thereof, but cannot turn with relation thereto. The sleeve 17 is provided with radial sockets 22, formed integral therewith, and these sockets are adapted to receive bars or levers which turn the head.
In the use ot the device, the head 11 or 1:2, depending upon the size of the nipple to be turned, is inserted into the radiator section and into the nipple 14L. The turning head 16 then shilted longitudinally of the bar or rod 10, to bring the same into close relation to the outer end of the radiator section. The head 16 is turned by the lever or rod inserted in the sockets 12, as is obvious.
While it is preferred to equip the turning head With the liners 18, so that they may be replaced, when Worn, the invention is of course not restricted to this feature, as the turning head may be splined upon the rod or bar, to turn therewith, and move longitudinally tlereoit', by any suitable means.
It is to be understood that the form 01":
' my invention herewith shown and described opposite ends With} nipple engaging heads of different sizes, said rod having a groove extending between the heads, a turning head having a bore, and a. liner removably mounted Within the bore of the head and having a here to slidably receive the rod. said liner having a part entering the groove.
2. A radiator wrench comprising a rigid rod of substantial length provided at opposite ends With nipple engaging heads, said rod having grooves extending between the heads for a major portion of the length of the rod, a turning head having a bore, and a two-part liner removably mounted Within the bore oi": the head and having a bore to slidably receive the rod, said liner parts having tongues to enter the grooves.
In testimony whereof I aflix my signature.
