Definitions
- This invention relates to sewing machines and particularly to the construction and manufacture of the bodies thereof. It is the aim of the invention to provide a sewing machine body, consisting of bed plate, standard, arm and head, in a simpler way than heretofore, without sacrifice of the rigidity thereof.
- Machine bodies of the type in question are manufactured from two members or halves, which are interconnected, as by means of fastening screws or the like, along a longitudinal vertical seam of the body when mounted.
- This enablessaid members to be produced by die casting, without use of cores, which materially simplifies production.
- said members must be so interconnected that they when mounted provide a machine body having the same rigidity as body moulded in one piece. This could not be attained by means of fastening screws only, since such screws could not be so accurately fitted in, that said members thereafter have no possibility of sliding a little relatively to each other, whereby the machine body will have insufficient strength against bending at right angles to the longitudinal seam thereof.
- the driving mechanism mounted in the machine body is then apt to come out of order.
- the invention aims at preventing such relative sliding or displacement of the body halves or members, and is principally distinguished by the feature that said members are integrally therewith provided with a suitable number of cooperating portions adapted for rigid interengagement when said members are pressed towards each other.
- Said portions may take the form of studs and recesses respectively, and if desired holes for securing screws may be provided therein.
- FIG. 1 The annexed, more or less diagrammatical, drawing illustrates by way of example an embodiment of a sewing machine body according to the invention.
- the driving mechanism to be located in this body may be of any suitable type and is not shown, for sake of simplicity.
- Figure 1 is a side view of one body member as seen from that side thereof, which is to face and become attached to the other body member.
- Figure 2 is a view of the assembled bed plate as seen from below.
- Figure 3 is an end view of the assembled sewing machine body
- Figure 4 illustrates, on a larger scale, a partial section through a tapered stud and recess, prior to the members having been entirely assembled.
- the sewing machine body comprises two halves l, 2, 3, 4 and I, 2, 3', 4 respectively, which in the embodiment shown are substantially symmetrical to a vertical longitudinal middle plane through the joint 5 ( Figures 2 and 3).
- Each half is cast as an integral member, and when the halves have been assembled the bottom portions 1 and I respectively form the bed plate, of U-shaped cross section, the portions 2 and 2', 3 and 3', 4 and 4' forming the machine standard, the machine arm and the machine head respectively.
- the numeral 6 ( Figure 1) indicates the abutment edge portions of one body half, adapted for abutting against a corresponding abutment edge portion on the other body half. In each of said abutment edges are provided grooves I of semicircular cross section, adapted to form supports for shafts of the driving mechanism (not shown).
- the manufacture thereof is simplified, since said halves may be produced by die casting, without use of moulding cores.
- the body halves are interconnected by means of transversely of the body extending screws l6, which are inserted through holes 8 provided in the abutment edge portions of said-halves.
- screws [6 are located near to the grooves 1.
- the assembled body would not attain sufficient rigidity, especially in transverse direction thereof. Screws could never be so accurately fitted into the screw holes, that no relative displacement of the body halves would appear, and such possibility of displacement would have the effect that the rigidity of the machine body at right angles to the joint becomes insufficient.
- the invention provides, at the abutment faces of each of said halves, a suitable number of projections for cooperation with corresponding depressions or recesses in the other half member, said projections and recesses being brought into rigid interengagement when the halves are drawn towards each other by tightening of the screws.
- the projections are preferably moulded or cast integrally with the half member in question, and may have any desired shape, being for instance tapered studs or ribs of any suitable dimensions, the recesses in the other half being correspondingly shaped and dimensioned.
- the projections and recesses may have so large abutment areas, that deformation (upsetting) during assembling is with certainty avoided.
- Figure 4 shows a suitable arrangement of a projection and its cooperating recess. The pro-.
- jection forms a tapered wart 9 on one body half, adapted to be received in a corresponding recess It in the other body half.
- a screw hole 8 may extend through said wart and through the bottom of the recess, or may be situated adjacent thereto.
- the projections may also take the shape of oblong wedges and recesses, as shown at the abutment edges of the ribs I3, l3, situated between the base plate side walls ( Figure 2). Wedge H and its corresponding recess are directed so as to prevent relative displacement of the body halves in the longitudinal direction thereof, but may also, as indicated at M, Figure 3, be so directed, or provided with lugs and recesses respectively, that relative displacement of the body halves in the height direction is prevented.
- a certain effect may also be obtained by interwelding the body members at certain places.
- a combination of projections and recesses with such welding is within the scope of the invention.
- a sewing machine body comprising in combination two body halves; two contacting faces on said body halves superimposed upon each other; a plurality of tapered recesses in the contacting face of the first of said body halves; a plurality of tapered projections in thecontacting face of the second of said body halves; a plurality of screw holes in said first body half passing through the bottoms of said tapered recesses; a plurality of screw holes in said second body half passing through the tops of said tapered projections and corresponding to said screw holes in said first body half; and screws provided in said screw holes for securing said body halves together.
- sewing machine body comprising in combination two body halves; two contacting faces on. said body halves superimposed upon each other; a plurality of recesses in the contacting face of the first of said body halves; a plurality of projections in the contacting face of the second of said body halves; a plurality of screw holes in said first body half passing through the bottoms of said. recesses; a
- a sewing machine body comprising in combination two body halves; two contacting faces on said body halves superimposed upon each other; at least one tapered recess arranged in the contacting face of the first of said body halves and having a bottom portion; at least one tapered projection arranged in the contacting face of the second of said body halves and having a top portion; a screw hole in said first body half passing through said bottom portion of said tapered recess; a screw hole in said second body half passing through said top portion of said tapered projection and arranged so as to correspond to said screw hole in said first body half; and a screw passing through said screw holes securing said body halves to each other.
- a sewing machine body comprising in combination two body halves; two contacting faces on said body halves superimposed upon each other; at least one recess arranged in the contacting face of the first of said body halves and having a bottom portion; at least one projection arranged in the contact ing face of the second of said body halves and having a top portion; a screw hole in said first body half passing through said bottom portion of said recess; a screw hole in said second body half passing through said top portion of said projection and arranged so as to correspond to said screw hole in said first body half; and a screw passing through said screw holes securing said body halves to each other.
