w. BE-RSSENBRUGGE 1 Filed March 22. 1928 Patented Mar. 29, 1932 Unites rains ATENT DFFICE ZPROGESS OF APPLYING CORNER-IRONS TO TABLES Original application filed March 22, 1928, Serial No, 263,808. Divided and this application filed. February 23, 1929. Serial No. 342,087.

l and to the process of applying such irons;

and one of the objects of the invention is the provision of an improved process for applying corner irons so as to eliminate the necessity of using auxiliary fasteners, but which secures the corner irons in place in interlocked engagement with the top of the table.

A further object of the invention is the provision of a new and improved process of the above character wherein the corner iron is applied to the table and interengaged therewith in such manner as to prevent displacement through a single movement, whereby a number of the corner irons may be quickly and readily applied in a very short space of time.

A further object of the invention is the provision of a novel process of the above character wherein the corner iron is readily placed in position in a semi-formed condition and through the operation of clamping members, parts of the iron are imbedded in a portion of the table top so as to securely retain the iron against movement after being clamped in position.

WVith the above and other objects in view, the invention consists in the novel features of construction, the combination and ar-' rangement of parts hereinafter more fully set forth, pointed out in the claim, and shown in the accompanying drawings wherein:

Figure 1 is a detailed top plan view of the portion of the table with the corner in position adjacent one of the clamping members;

Figure 2 is a detailed section on the line 22 of Figure 1 showing the clamping members in a clamped position;

Figure 3 is a view similar to Figure 2, showing the relative position of the corner arm and the clamps prior to the movement toward each other of the clamping members;

Figure 4 is adetailed section through the guide member with the movable clamping member shown in top plan view and with its stem in section; p I

Figure 5 is a View from the under side of one of the corners of the table;

Figure 6 is a side elevation of the corner iron; and

Figure 7 is a perspective view of the corner Referring to the drawings wherein I have illustrated the steps employed in my improved process, it will be noted that in Figure 1' I have illustrated one corner of a table top 1. These tabletops in the construction are usually provided along their outer edges with a groove 2 in which the cover applied to the table is secured, and it is in this groove that one portion of the corner iron is fitted for retaining the same in position.

In Figure 6, I have illustrated a side elevation of the corner iron which includes an angular body 3 having arms 4: at one end which are positioned at right angles to each other to correspond with the corner of the table, and these arms while illustrated as areuat-e in cross-section may be made of various shapes according to the type of the. table to which the corner iron is to be applied. At the other end of the body, I provide the tapering prongs 5 which are also disposed at right angles to each other and provided with a penetrating point for penetrating thematerial of the table top. It will be apparent that the body of the corner iron may be made in fanciful designs but preferably angular in shape.

In applying the corner iron to the table top, I use die members one of which is stationary and the other movable, the stationary die being designated by the numeral 6 and the movable die designated by the numeral 7 These die members area part of my improvedmas chine illustrated in my before mentioned patent, the constructionand operation of which is fully explained in said patent. The stationary die'member 6 is provided with an arcuate recess 8 adapted to embrace the arcuate arms 4 of the corner iron, it being understood that the stationarydie member is a of right-angular form and the recess 8 extending through both angular portions of the die.

, "The movable diemember 7 is formed with securely retain the iron angularly disposed arcuate depressions 9 adapted to co-operate with the tongues 5 in the application of the corner iron. In placing the corner iron in position and clamping the same to the table top, theironis first positioned with the arms 4- engagi'ng over the edge of the side walls of the-tabletop with the inner edges of the arms at extending into the groove2 as illustrated in Figure. 3. The corner is then positioned between the -die;

members as shown in Figure 3 and the die member? moved toward the die member 6, the prongs 5'co-0perating with the depressions 9, the'shape'of the depressions causing the prongs to be bent upon themse'lvesso that the points thereoffwil-lbe forced into engagement with theunder sideof the edges of the table top "as-shown'in Figure 2. The movement of the die member 7 is sulficientto cause the points ofthe prongs 5 to penetrate "the material of the table top so as to securely retain the corner irons against movement.

In Figure'5, I haveillustrated a bottom or underside View of the table top showing hoW the prongs 5 penetrate the material of the tabletop and" imbed themselves so as to members against movement.

I claim:

The process of locking corner-irons of the type embodying arcuate top flanges, depending side walls and straight penetrating prongs to the corners of tables, which consists in fi'rstengagin-g the top flanges overnthe table top, with the penetrating prongs disposed lowermost; second, positioning the corneriron between companion die members having arcuate faces for engaging the upper and :lower ends of the corner-iron; third, applying pressure to the ends of the corner-iron through the medium of said die members, whereby the arcuate flanges of the corner-iron are vurged into penetrating engagement with one face 'of'the corner of thetableand the penetrating prongs are'retained' inhooked engagement with the other face of the corner of the table.

In "testimony that I claim the foregoing I havehereunto se't my hand at Milwaukee, in

the county of 'Milwaukee and State of. VVisconsin.

' WILLIAM BERSSENBRUGGE.

The process is extremely simple due to the 7 turn'the tpron'gs 5 and cause the points thereofto i'mbed themselves in the-material of the table top.

It will'be apparent from the above that I have provided a simple and eflici'ent process for applying corner irons to table tops, whereby a great many of the corner irons will be applied in a very short space of time; and if the process is carried out with 'the'use 'ofmy improved machine as stated heretofore,

it'will salve considerable expense in placingthis type of table on the market, which is 7 generally used as a card-table or'the like,

While Ihave shown and described thepreferred embodiment of my invention, it; will 7 beapparent that slight changes may be made in theconstruction when putting theinvention into practice Without departing from the spirit of :the sameor 't'he 'scop-e of' the appended: claim,
