11 Claims. This invention, relates to improvements in said adaptation to a quilting frame and to a table..

With particular reference to the quilting frame. the main purpose to be achieved is the insurance of a firm support for the material to be quilted. It is desirable and necessary that the quilt foundai tion shall run true and remain true during the v entire quilting operation so as to avoid-any material distortion of the pattern. With this preamble in mind the objects of r the invention-are as follows:

First, to provide a work support of the moreor less commonly known knock-downtype, comprising structural principles which'are equally well adaptable to the quilting frame and :table, herein shown as two modes of carrying out the semi-circular recesses 8, 9 (Fig. 2) which when invention.

Second, to provide a hinge foreach of the above adaptations of the invention, which insures Third, to provide a hinge of the foregoing character which will keep the respective leg from turning when the clamp members arerseparated Ordinarily this wing nut is conveniently placed on 39 to loosen their hold upon the quilt rods.

Fourth, to provide a novel leg pivot which in Figure 8 is a detail sectional view taken on the line 8-8 of Fig. 6.

Reference is first made to the adaptation of the invention as a quilting frame. This frame is generally designated I in each of Figs. 1 to 5. 5 It, comprises a pair of end frame members 2,- 3, and inasmuch as theseare almost identical in construction, the initial description is confined to the nearest frame member 2. All parts which are-identical in the members 2, 3 are designated 10 with corresponding reference numerals.

'I'heend frame member 2 consists of a pair of clamp members 4, 5 which are provided with serrations 6 along their confronting surfaces.

These serrations may extend full length of the 5 ably occupies an opening in the companion i.

At eachend the members 4, 5 have matching brought together by the closure of the members produce a cylindrical hole in which one end of the respective quilt rod Ill is seated. There are 25 two quilt rods and each is designated 10.

Abore l l which is common to the confronting clampmembers 4, 5, contains a bolt l2 which has a wing nut 13 screwed onto its threaded end.

top of the uppermost clamp member 4, the head l4 of the bolt being underneath of the clamp member 5. A counter-bore l5 provides a recess Other objects and-advantages will appear in; the following specificatiom-reference being had to the accompanying drawing,.in which:-

aportion being shown in section, of the hinge of the nearest end frame of the clamp member 5 (Figs. 1 and 3). A rivet 20 is so driven across the member 5 as to prevent for a spring l6 which separates the clamp members whenthe wing nut I3 is unscrewed. There is a recess ll adjacent to the extremity of the member 4 and the companion 5 has a neath the recess and opens at 19 at the extremity 4 splitting of the Wood of which the quilting frame is commonly made because of the weakening of the member 4 by reason of the presence of the Figure 4 is a horizontal section taken on the V line 4-4 of Fig. 3.

.- hole in this web and the web l4 rests against it as shown.

Enlargements 25 of the side plates 22 provide 55 ferrules 32.

the knuckles for a hinge pin 26. This hinge pin occupies a position beneath the clamp member 5, and although it stands crosswise of the end frame member 2, yet it is centered upon the axis of the recess H. For these purposes the lmuckles 25 necessarily extend below the clamp member 5 so as to enable securing the ends of the hinge pin to the knuckles in any preferred way. According to Fig. 4 said hinge pin comprises a bolt-which is headed at one end and has a securing nut 21 on the other end.

It is to be observed that the side plates 22 of the hinge 23 have extensions 28 which protrude into the Zone of the hole 8, 9. This arrangement has the important purpose of limiting the position of the quilt rods II] in respect to the endframe member 2. Each quilt rod has an annular groove 29 (Figs. 2 and 4) adjacent to one ofits ends. This groove is so spaced in from the respective end that when said end abuts the extension 28 of the outermost side plate 22 (Fig. 1) the groove will register with the extension 28 of the innermost side plate so that said extension can be seated in the groove. The extensions 28 thus virtually bite into the quilt rods I and provide a lock for the quilt rods I!) in the nearest frame member 2 (Fig. 1). The opposite ends ofthe quilt rods IE1 are smooth, that is to say; they do not have annular grooves. Consequently, the end frame member 3 may be adjusted in along the rods as far as desired, depending upon the width of quilt in the course of manufacture.

Reverting to the hinge pin 26, this provides a pivot for the leg 30' (Fig. 2). The pin goes through the leg at such a place as to leave what is conveniently termed a lock end 3!. This lockend is adapted to occupy both the recesses H and slot I 8 (Fig. 3) when the wing nut I3- is screwed down to close the clamp members 4, (Fig. 2) and when this condition is arrived at the leg 30' is held as a perfectly rigid part of the respective frame member.

Brace means is used in conjunction with the hinge pin 26, comprising a pair of suitably made These comprise matching members (Fig. 4) which have semi-circular recesses 33 matching the cross-sectional shape of the leg 30. As the hinge pin 25 is secured in place the two half-ferrules close in upon the leg, bracing the latter against any possible splitting which might occur because of the presence of the hinge pin.

Attention is now directed to Fig. 5. As. already stated, the structure here is identical with that of the end frame 2, the only difference lying in the structure of the hinge 23. The side plates 22' are cut off at 34 by rounding or otherwise, thus. eliminating the previously described extensions 28 at this particular location. The hole consisting of the semi-circular recess 8, 9, is thus unobstructed, making it possible to slide the endv frame member 3 freely upon the quilt rods I0 when adjustments for quilt widths are required.

Mention has been made of the adaptation of the quilting frame structure toa table. This modification is illustrated in Figs. 6, 7 and 8. The table is generally designated 35.. Those parts of the end frame members which are identical with the frame members 2, 3, in Fig. 1, are similarly designated as before, but with the exponent letter a added. Instead of the. comparatively long quilt rods l0 being used, shorter rods 36 are employed so as to space the frame members 211., 3a, much more closely than before. In this arrangement the rods 36 can be grooved on each end as at 29 (Fig. 2), and instead of using a hinge knuckles 25a of the hinge plates.

on the frame member 30. as shown in Fig. 5 both hinges 23a can be made with the extensions 28a so as to limit and lock the rods 36 at both ends.

A cover or table top 3! of any desired material, for example ply wood, is secured to the end frame members 2a, 3a by simply reversing the bolts i2a (Fig. 8.) This places the wing nuts 13a on the underside, and in order to enable swinging the legs 38 to the closed positions (Fig.7), each leg is recessedat 39 so as to. make room for the adjacent wing nut. The legs 38 are pivoted upon hinge pins as before, but instead of the slot 18 occurring in each bottom clamp member 5a, the ends of the latter are cut off at 40 (Fig. 8). The lock end 31a, of each leg is now made cross-sectionally square to exactly fit between the The extremity of each lock end is turned into a boss 4|, and when the clamp members are closed the bosses 4! occupy the recess Ma.

The cross-sectionally square material of which a pair of the legs 38 is made, is sawed on a longitudinal angle 42 (Fig. 7) This produces tapering legs (Fig. 6) but this arrangement also enables: a close fitting of" the legs when the respec tive frame member is closed (Fig. '7). The table will'have so many uses that it is thought unnecessary toenlarge upon them other than to state that the table structure is well adapted to such purposes as camping, card-playing and the like.

Now reverting to the quilting frame I, it will be understood that a pair of ends of the quilt foundation 43- are rolled upon the respective rods H3 These rods havestrips of fabric 44 tacked to them and the ends of the quilt foundation 43 are pinned to these fabric strips. The latter are shown extended in dotted lines in Fig. 1, but inasmuch as the quilt is' supposed to be rolled upon the rods H1 at its ends it follows that the fabric strips 44 are actually in a rolled condition. Slack at the opposite ends 45 of the quilt foundation 43 is taken up by providing the frame members 2-,

3, with strips 46 to which said ends 45 are pinned.

Upon desiring to nest the legs 38 upon the frame members 2, 3, the unscrewing of the wing nuts l3 enables the springs I6 to spread the clamp members 4, 5 (Fig. 3). The wing nuts I3 must be unscrewed a sufficient distance to cause the raising of the clamp members 4 above the extremities of the lock ends 3| (Fig. 3) whereupon the legs canbe swung as indicated by dotted lines. The legs of each frame member can be sprung enough to make them lie sufficiently close to the clamp member 5 and thus make a fairly compact bundle. Upon desiring to adjust the frame memher 3 along the quilt rods it is sufficient to unscrew the wing nuts 13 only enough to release gripofthe clamp members upon the smooth ends 'of the. rods. The adjustment can then be made and there will be no danger of the legs 30 of said frame member being turned out of position; this occurring; only when the wing nuts 13 are adjusted comparatively high up. When the frame stands in its assembled condition the enclosure of the extremity of each lock end 3| in the recess I'I produces an interlock with the respective clamp member 4 that holds the lock end firmly against the base of the slot, 18 so that it is impossible for the leg 30 to turn on its pivot 26.
