FASTENER Filed Sept. 8, 194'! James 7 King,

Patented Apr. 12, 1949 UNITED STATES FASTENER James Thomas King, n at ng, c nt, Application September 8, 194-7, Serial No. 772,845

3 Claims.

My invention relates to devices for securing two or: more parts together under tension, and itparticularlyhas for its obj ects 1. To. provide a fastener of general application which can beused to. hold two or more .woodor metal parts together, yet capable of being .re= moved with no loss of parts.

2. To provide such a fastener as can be tightened from time to time so as always to ensure a good and reliable means to hold two parts together, which parts due to shrinkage tend to loosen up.

3. To provide a fastener whose parts can be made of sheet metal and by a punch press process.

4. To provide a fastener which can be installed or removed in diflicult or confined spaces.

Other objects will in part be obvious and in part will appear later.

To the attainment of the aforesaid objects and ends, invention resides in the novel features of construction, combination, and arrangement of parts, all of which will first be fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings in which- Fig. l is a view showing my invention as used for securing a table or desk top in place, a portion of the table top and a portion of the table side being shown in section, while the fastener is shown in elevation.

Fig. 2 is an elevational View looking from right to left in Fig. 1.

Fig. 3 is a plan view of the socket member blank before bending it to shape.

Fig. 4 is a plan view of the retainer member before it is bent to shape.

Fig. 5 is a side elevation of the retainer.

Fig. 6 is an elevational view looking from right to left in Fig. 5.

Fig. '7 is an inverted plan view of the retainer.

Fig. 8 is a plan view of a T-bolt blank.

Fig. 9 is a side elevation of the completed T- bolt.

Fig. 10 is a front view of the same.

Fig. 11 is a cross section on the line IIII of Fig. 6.

In the drawings, in which like numerals of reference indicate like parts in all the fingers, I represents a table top and 2 the table side to which the top is to be secured.

The fastener in this case comprises four parts: a retainer, a socket member, a T-bolt, and a nut.

The retainer (Fig. 4) comprises a back wall 3,

extensions 4, stem"memb.ers 9 project. The retainer is formed in one piece from a sheet metal blank which is stamped to the shape shown and slit as at I and B. The blank is bent, in suitable dies, along the dot and dash line 6 to the form shown in Fig. 5, and the stem members are formed into one-quarter cylinders as shown in Fig. 6, forming one-half of a non-threaded stem to cooperate with the T-bolt semi-cylindrical stem I2, I3, shown best in Figs. 9 and 10. The wall 3 has holes ID for fastening screws I9, that serve to secure the retainer to the table side 2.

The T-bolt is formed from a blank shown in Fig. 8 wherein II indicates the head part, I2 the unthreaded neck part, and I3 the stem proper which, When the blank has been shaped and the thread pressed thereon, will appear as in Figs. 9 and 10.

(Fig. 3) I4 designates a socket member having a hole IT for the passage of the stem I3, and having screw holes I8, sides I5, and ends I6. The socket member is stamped from sheet metal after which the sides and ends are bent at right angles along the dot and dash lines I5", I6

After securing the retainer to the table side 2 by screws I9 and after passing the threaded stem I3 through the hole I1, and the stems I3 and 9 are brought to cooperating position, a nut 2| is threaded on the stem I3 over the stem 9. Before tightening the nut, however, the socket member is secured by screws 20 to the under side of the table top. Upon tightening up on the nut, the parts I and 2 are clamped together.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction and advantages of my invention will be clear to those skilled in the art to which it appertains.

What I claim is:

1. Means for securing a table top to a table side, said means comprising a metal retainer of U-shape in plan view and T-shape in side elevation, screws passing through said retainer for mounting said retainer on the table side, said retainer having a pair of stem members each of quarter cylindrical form held in contact to comprise a semi-cylindrical stem; a socket comprising a plate portion and side and end flanges, said plate portion having a stem passage, screws passing through said socket for securing said socket to the under side of the table top; a T-bolt having a-socket-engaging head and a threaded semi-cylindrical stem said stems cooperating to form a substantially cylindrical stem; and a nut shallow sides 5, andsideextensions 4. From the.

on said stems and engaging said retainer and the threaded stem for drawing said table top in tight contact with said table side.

2. A means for securing two parts together in contact, one at right angles to the other, said means including a retainer composed of sheet metal and including a back with screw-passing apertures, two sides of inverted L-shape in side elevation from each of which sides a quarter-- cylindrical stem extends in parallel relation to the back and to one another, said means further including a sheet metal socket member having a bottom and four sides, the bottom having screwpassing holes and a stem passage, said means cylindrical stem extends in parallel relation to the back and to one another, said means further including a sheet metal socket member having a bottom and four sides, the bottom having screwpassing holes and a stem passage, said means further including a T-bolt whose head lies within said socket member and whose stem passes through said stem passage into cooperative position with respect to said first mentioned stem, the T-bolt stem being threaded, said stems cooperating to form a substantially cylindrical stem, and a nut on said stems, said T-bolt and its stem being composed of sheet metal.
