Description

Jan. 14, 1958 G. B. STILLWAGON, JR 2,819,596
PINNING CONSTRUCTION FOR UNIVERSAL JOINT Filed May 5, 1955 INVENTOR. 660265 51 sr/u W4GOA/ JEZ United States Patent PINNING CONSTRUCTION FOR UNIVERSAL JOINT George B. Stillwagon, Jr., Dayton, Ohio, assignor of onehalf to Kenneth G. Fraser, Dayton, Ohio Application May 5, 1955, Serial No. 506,126
4 Claims. (CI. 6417) This invention relates to pinning construction for universal joints, and the method of making same, and more particularly to an improved central block and arm or pinning attachment.
The invention has for its object the provision of a simple construction which is easily and inexpensively assembled, and one which will be efiicient, durable and permanent.
Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.
In the drawings,
Figure 1 is a top plan view of the pinning construction.
Figure 2 is an end view taken in the direction of the arrow 2 of Figure 1, wherein the pinning construction is only partially completed and wherein a portion is broken away to illustrate the assembly of the device.
Figure 3 is a vertical cross section taken substantially on the line 3-3 of Figure 1.
Figure 4 is a perspective view of the device.
Figure 5 is a perspective view of a modification; and
Figure 6 is a cross sectional view of the modification.
Referring more in detail to the drawing, a block 10 is provided with three mutually perpendicular or normally positioned intersecting borings. In assembling the device, a pin 12 is inserted into and through one of the borings. Its ends protrude through the block on opposite sides thereof to form oppositely extending arms 14 and 16.
The mid-section 18 of the pin 12 is shown square or rectangular in cross section in Figures 2 and 3; but it is to be understood that the device is not limited to this configuration. It may be of any configuration which will allow its partial entrance between the lip sections 20 and 22 of an arm 24, positioned in another one of the borings, and sufficiently reduced in size so that shoulders 25 are formed which prevent the withdrawal of the pin 12 after the arm 24 is swaged in place.
An arm 26 similar to the arm 24 is placed in alignment therewith at the opposite end of the boring occupied by the arm 24. The arm 26 is also provided at its inwardly extending end with a pair of lips 28 and 30, which also embrace the mid-section 18 of the pin 12. These arms 24 and 26 are swaged in place and the lips 20, 22, 28 and 30, when forced against the mid-section 18, arch outwardly to become shoulders projecting into the third boring. These shoulders prevent disengagement of the arms 24 and 26 from the block 10.
In the event of a lateral movement of the pin 12, the shoulders 25 engage the lips or shoulders 20, 22, 28 and 30, to prevent the withdrawal of the pin 12 from the block. Ordinarily, however, there is no play between the shoulders 25 and the lips 20, 22, 28 and 30.
Figure 2 shows the arm 24 and the lips 20 and 22 be- See fore the swaging operation. It also shows the lips 28 and 30 of the arm 26 after the swaging operation has been completed. In Figures 3 and 4 the swaging operation has been completed.
In the modification shown in Figures 5 and 6, a modified block 40 is used, wherein the third boring is omitted. The block 40 is provided with normally positioned first and second borings, the second of which is enlarged at the center of the block. The enlarged portion forms a cylindrical cavity 42 which allows for the outward expansion of the lips 20, 22, 28 and 30,, of the arms 24 and 26, positioned in the second boring. The cavity also provides shoulders 44 and 46 which act as stops to prevent the arched lip portions 20, 22, 28 and 30 from becoming disengaged from the block 40. In all other respects the pin and arm construction is identical with the form of the invention described above relative to Figures 1 to 4 inelusive.
Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention, various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
Having thus described my invention, I claim:
1. A pinning construction for a universal joint comprising a block provided with first and second normally disposed borings intersecting in the center thereof, a pin extending through said first boring and terminating at its opposite ends in cylindrical arms protruding from said block, said pin having a reduced mid-section of rectangular cross section extending diametrically within said second boring, a pair of arms, there being one arm seated in each end of said second boring and protruding from said block, swaged lips on the inner end of each said arm engaging and interlocking with the rectangular mid-section of said pin, said block having a cavity therein into which the swaged lips project whereby said pin and said arms are non-rotatably retained in said block.
2. A pinning construction according to claim 1, wherein the cavity in said block into which the swaged lips project is provided by a third boring extending normal to and intersecting the first and second borings of said block at the center thereof.
3. A pinning construction according to claim 1, wherein the cavity in said block into which. the swaged lips project is provided by increasing the diameter of said second boring in the center of said block.
4. A pinning construction for a universal joint comprising a block provided with first and second normally disposed borings intersecting in the center thereof, a pin extending through said first boring and terminating at its opposite ends in cylindrical arms protruding from said block, said pin having a reduced mid-section of non-circular cross section extending diametrically within said second boring, a pair of arms, there being one arm seated in each end of said second boring and protruding from said block, swaged lips on the inner end of each said arm engaging and interlocking with the non-circular mid-section of said pin, said block having a cavity therein into which the swaged lips project whereby said pin and said arms are non-rotatably retained in said block.
