' Fig. .6 is a. vertical sectional View through the supporting post in a plane parallel with so the line of feed.
The invention is directed to a throat plate support for sewing machines, and more particularly to a sewing machine of'the type wherein there is men. work support. The
is supporting bed is provided with the usual bracket formed integral therewith in which the main shaft of the machine jOllIIlnlGCl. Tzhis. supporting bracketserves as one of the supporting means for'the supporting e 11- so berwhich carries the throat plate: Spaced from this supporting bracket is a supporting post which is disposed onthe opposite side of the feed bar from the bracket and this post serves as an additional supporting means for the support which carries the throat plate. The support carrying the throat plate is provided with a portion which egitends lengthwise of the" bracket and said portion is firmly secured to the bracket.
It is also provided with spaced projection jecting portion at .tlie'front of thesupp ort for the throat plate overhangs the bracket so as to give 'fredom for the 'looper mechanism. i
Referring more in detail to the drawings, the invention is shown as applied to a sewing machine which includes a supporting bed '1 which may be'of the usual construction. tending upwardly from the supporting bed is a bracket 2 which is formed integra'lwith the bed. The main shaft, indicated at 3, is .journaled inthis bracket. Mounted on top of the bracket 2 the'supporting member 4 for the throat plate. This supporting mem her .4: includes a'portion which extends lengthwise of the upper end of the bracket 2 and said support projects beyond said bracket slightly); The support is secured to the bracket by screws'o, 5. Spaced from the bracket 2 isa post 6 which is ri idly attached to the bed of the machine. The feed bar is disposed between this bracket .2 and the post .6. "The feed bar is indicated in Fig. 3 of the drawings at 7. Said feed bar carries a feed dog 8. The feed'baris raised and lowerec and moved back and forth by the usual operating means therefor.
The support 4- is also provided with a laterally porjecting portion 11. The laterally projecting portion 11 is spaced from the projecting portion 9. The projecting portion 9 is well in rear of the needle and the feed dog, while the projecting portion 11 is well in front of the needle and the feed dog. The throat plate is indicated at 12 in the drawings. Said throat plate is provided with the usual feed slots 13, 13 and the needle openings 1 2 through which the needles pass. The threat plate at its rear end rests on the projecting portion 9 and is secured thereto by screws 16. The rojecting portion 11 overhangs a portion of the looper operating mechanism. lVhile I have shown the support 4 as mounted on the bracket at one side of the line of feed and on a postat the other side of the line of feed, it will be understood that other ways may be provided for mounting this support which carries the throat plate. The esential feature resides in the provision of some rigid supporting means for this member and the providing of the member with spaced projecting portions one in front of the needles and the other in rear thereof on which the throat plate may be mounted.
The loopers are indicated at 17 in the drawings. These loopers are mounted on a looper carrier which is oscillated by a suitable link 19. The loopers are, of course, located beneath the throat plate, as clearly indicated in Fig. 4. The throat plate bridges across from one projecting member 9 to the other projecting portion 1]. The support for the throat plate is firmly secured to the bracle et 2 and to the post 6 and this serves as a sole supporting means for the member which carries the throat plate. By placing the post 6 well to the right of the line of feed and the supporting bracket 2 well to the left of the line of feed, a very rigid support is provided for the throat plate. The cloth plate is indicated in part at 20 in Fig. l of the drawings. The cloth plate rests upon the support for the throat plate and is secured thereto by a suitable screw 21. The cloth plate extends about the throat plate and serves as a support for the material being stitched as it passes onto and off from the throat plate. This cloth plate, as noted, is mounted on the support for the throat plate and the support for the throat plate also serves in part as a support for the cloth plate.
Other supporting means is also provided for the cloth plate. y releasing the screws, the cloth plate can be removed from the machine and without in any way interfering with the throat plate, the throat plate remaining attached to the supporting member 4r therefor.
Thus it is that the cloth plate can be re-- moved and the machine operated for stitching with all of the parts beneath the cloth plate readily acessible for adjustment if desired.
It is obvious that minor changes in the de-- tails of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims Havin g fully described my invention, what I claim as new Y and desire to secure by Letters Patent, is
1. In a sewing machine a supporting bed, a bracket formed integral therewith and disposed at one side of the line of feed, a supporting post disposed at the other side of the line of feed and in rear of the needles, a supporting member mounted on said bracket and having an integral lateral projection in rear of the needles resting thereon and secured to said supporting post and bridging the feed bar of the machine, said support having a laterally projecting portion in front of the needles overhanging the bracket, a throat plate secured at its rear end to the laterally projecting portion of the support in rear of the needles and at its front end to the laterally projecting portion of the support in front of the needles.
2. In a sewing machine a bed, a bracket formed integral therewith and disposed at one side of the line of feed, a supporting post rigidly attached to said bed and disposed at. the other side of the line of feed, a support mounted on said bracket and post and having spaced laterally projecting portions, a throat plate secured to said laterally projecting portions and bridging the space between the same, a cloth plate, and means for supporting said cloth plate independently of the throat plate whereby the cloth plate may be removed from the machine without disturbing the throat plate and the machine operated for sitching.
8. In a sewing machine a supporting bed, a bracket formed integral therewith and disposed at one side of the line of feed, a supporting post disposed at the other side of the line of feed and in rear of the needles, a supporting member mounted on said bracket and having an integral lateral projection in rear of the needles resting thereon and secured to said supporting post and bridging the feed bar of the machine, said support having a. laterally projecting portion in front of the needles overhanging the bracket, a threat plate secured at its rear end to the laterally projecting portion of the support in rear of the needles and at its front end to the laterally projecting portion of the support in front of the needles, a cloth plate, and means for supporting said cloth plate independently of the throat plate whereby the cloth plate may be removed from the machine without disturbing the throat plate and the machine operated for stitching. V b 4. In a sewing machine, a bed, a bracket rising therefrom and disposed at one side of the line of feed, a support mounted on said bracket and having spaced parallel members extending transversely of the line of feed, a throat plate secured to said members and bridging the space therebetween, and a cloth plate above said support and extending about said throat plate.
5. In a sewing machine, a bed, a bracket rising therefrom and disposed. at one side of the line of feed, a second bracket rising from said bed at the other side of the line of feed, a support mounted on said brackets and having spaced parallel members extending trans versely of the line of feed, a throat plate secured to said members and bridging the space therebetween, and a cloth plate above said support and extending about said throatplate.
In testimony whereof, I affix my signature.
