S. P. HULL Nov. 14, H950 JOINT Filed Jan. 5o, 1948 O @leas/,1i
INVENTOR. @5ml f. M
WZ' v ATTozPA/EY l? Q' Uh Patented Nov. 14, 1950 UNITED" STATES TENT OFFICE* This invention relates to couplings and more especially to an adjustable coupling.
A principal object of this invention is to produce a device for uniting two members so that relative Amovement will be prevented.
A lfurtherobject of this invention is the production of a `device of the type described in which adjustment of one-=i-nember relatively one to the other may be easily and quickly made.
A further object of the invention is the production of a device `ofthe type described which is so constructed that relative movement of two joined members will act to tighten the grip of the means connecting them.
Other objects and advantages will appear as thedescription of the particular physical embodimentselected -to illustrate vthe invention progresses and the novel features will be particularly pointed out in the appended claims.
In describing the invention in detail and the particular physical embodiment selected to illustrate the invention, reference will be had to the accompanying drawings and the several views thereon, in which like characters of reference designate like parts throughout the several views, and in which:
Fig. '1 is a longitudinal cross section of a pair of rods united by means of my invention; Fig. 2 is a front elevational view of the device as shown by Fig. 1; Fig. 3 is a cross sectional view of the device as shown by Fig. '1 on the plane indicated by the line III-III viewed in the direction of the arrows at the ends of the line; Fig. 4 is a cross sectional view of the device as shown in Fig. 1 on the plane indicated by the line IV-IV viewed in the direction of the arrows at the ends of the line; Fig. 5 is an exploded view of the parts illustrated in Fig. 1 omitting the connecting bolts.
In Fig. l, I have illustrated the rst rod or member I and a second rod or member 2 which are to be adjustably connected by means of my invention in such a manner that their relative positioning may be easily changed and when fully adjusted will remain in adjusted position resisting relative longitudinal movement thereof.
Rod or member I is formed with a plurality of through orifices 3.
Rod or member 2 is formed with two through slots 4 and 5. These slots have their greatest dimension longitudinally of the rod 2. The rod 2 has a groove 6 formed therein, and this groove has a sloping bottom. The slope starts from the line 'I and slopes in one direction, that is, to the left as viewed in Fig. 1, to the outer extremity 3 Claims. (Cl. 287-58) of the slot 4. The'bottom also slopes from the line 1 intermediate the slots 4 and 5to the right, as viewed in Fig. 1, tothe outer extremity of the slot 5.
Headed'threaded bolts 8 and `9 are passed through orifices 3 of`rod I Athrough slots as 4 and 5 and on the ends'thereof are nuts.
The nuts I0 and II- are formed with through threaded bores, as I2v and I3, to engage the threads of thebolts Band 9. The nuts I8 and II are formed with a sloping'face as I4"'and I5 to engage and abut against the sloping faces of the bottom of the groove `6 of the rod 2. The outer faces of the nut 'are preferably parallel to the longitudinal side face of ythe rod 2. The nuts Il) and I I are made of such length that their ends, as at I6, may abut one with the other'.
The bolts 8 and 9 are secured from turning, preferably by means of lock washers lI'I and I8 placed under the heads thereof.
When the two rods are united, as shown in Fig. 1, and the bolts 8 and 9 tightened, any relative movement between rods I and 2, as a movement of rod 2 in the direction of the arrow I9, will cause the bottom surface of the groove 6 to engage with the inclined surface I5 of the nut II, and tighten the grip of the bolt 9. Any movement of rod 2 in a direction opposite to the arrow I9 will cause the bottom surface of the groove 6 to contact the sloping face I4 of the nut I0 and so tighten the grip of the bolt 8. By the means described any attempt to relatively move rods I and 2 in a direction of their longitudinal axes so results in tightening the grip of the bolts that movement is completely resisted. Further, an attempt to move rod I in a direction opposite to the arrow I9 would tend to move nut I8 in a direction opposite to the arrow I9, which, abutting the nut I I, would tend to move nut II in a direction opposite the arrow i9 and so increase the grip of bolt 9 to resist such movement. The same action would take place if the movement were in the contrary direction, only, in that case, the nut II would tend to push the nut I 0. Due to this construction the shearing effect on the bolts is substantially equalized both in the case of a thrust or a pull.
v It is readily seen that the positioning of rods l and 2 may be relatively changed by simply removing the bolts, such as 8 and 9, and placing them through other through orifices, as 3, in the rod I. This operation is very readily and quickly performed and when completed the rods are again securely united as before.
.Although I have particularly described one parthrough orices; a second rod formed with two spaced longitudinal through slots and a groove of a length equal to the maximum space occupied by the two slots, said groove having a bottom sloping from a line intermediate the two slots in one direction longitudinally of the rod to the extremity of one groove and from the said line in the opposite direction to the extremity of the other groove; two nuts, each nut formed with a face adapted to abut the sloping bottom of the groove, one nut abutting one of the two slopes and the other abutting the other of the two slopes, the adjacent ends of the nuts abutting each other, each nut formed with a threaded through orifice; two headed threaded bolts, one bolt passing through one of the through orifices in the first rod and through a slot and into the threaded orifice in one nut, and the other bolt passing through another of the orifices in the first rod and through the other slot and into the threaded orifice in the other nut and means for preventing the turning of the bolts.
2. In an adjustable joint, including, in combination: a first member; a second member, bolts passing through both members; nuts on each bolt, one of said nuts and one of the members abutting along a face inclined to the longitudinal axis of the members and another of said nuts and the said one member abutting along a face inclined to the longitudinal axis of the members and to the other inclined face whereby a longitudinal moVement of a member relative to the other member tightens the grip of one or the other bolt and nut.
3. In a rod joint, including, in combination: a first rod formed with a through orif1ce; a second rod formed with two through slots lengthwise of the rod, said second rod also formed with a first surface inclined to the longitudinal axis of the rods and a second surface inclined to the 1ongitudinal axis of the rods and to the first said surface; a first nut formed with a through threaded. bore and a surface abutting the :rst mentioned surface and a second nut formed with a through threaded bore and a surface abutting the second mentioned inclined surface; a first headed threaded bolt passed through the orifice in the first rod, through the slot in the second rod and threaded into the threaded bore of the nut and a second headed threaded bolt passed through the orifice in the rst rod through the slot in the second rod and threaded into the threaded bore of the second nut and means for preventing the bolt from turning whereby relative movement of the rods in either direction tightens the grip of either one or the other of the bolts.
