Specification of Letters Patent.

Patented June 3, 1913.

Application filed November 2, 1908. Serial No. 460,582.

To all whom it may concern Be it known that we, WILLIAM Gnori-rn and JoI-IN O. HUFFMAN, both citizens of the United States, residing at Lakewood and Cleveland, respectively, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Sewing-Machines, of which the following is a full, clear, and exact description.

The present invention is directed to the provision of a closure for the openings commonly made through the end of the case of a sewing machine head, adjacent to the needle plate, and through the wooden portion of the platform of the table in the same locality. Such openings are commonly had for the purpose of inspecting the working parts of the machine beneath the needle and for the purpose of removing the bobbin case or other part when occasion requires.

The object of the invention has been to provide a plate to close this opening which shall be readily applied and held in either closed or open position.

It has been a further object to provide a plate of this character which may be removed entirely out of the way so that access may be had to the working part-s of the machine even when heavy material, such as coats or similar articles, or attachments are held beneath the presser foot.

The above objects and other desirable ad vantages it will be seen are attained by that embodiment of our invention described in the following specification and illustrated in the accompanying drawings, in which;

Figure 1 is an elevation of the portion of a sewing machine head at the presser foot end showing the relation of the operating parts and our closing plate which has been raised to the open posit-ion. Fig. 2 is a side elevation of the closing plate in raised or open position. Fig. 3 is a central longitudinal section through the closing plate and a port-ion of the needle plate illustrating the method of applying the plate in position and closing the same. Fig. 4: is a similar section on the line 44 of'Fig. 1 showing the plate in closed position. Fig. 5 is a top plan of one end of the head plate and the tableadjacent thereto showing the closing late in position. Fig. 6 is a similar View with the closing plate removed showing the ways on which it rests.

Our closing plate is, as above indicated,

designed to close the openings which are made in the base plate of the machine head adjacent to the needle plate and in the top of the table adjacent thereto in order that access may be had to the working parts beneath the needle. The body of this plate we construct in a single piece A designed to fit the two openings when in position. A suitable thumb not-ch A is provided at the outer edge of the plate for the purpose of permitting accessto the catch'by which the plate is held in its closed position, as will be hereinafter described.

()n the lower face of the plate near the inner end thereof we secure a retaining cross strip B having the ends thereof bent at right angles to the plane of the plate, the said ends being properly shaped to form retaining ears B fitting closely behind lateral. projections C extending from the edge of the base plate C about the opening. These serve to prevent the closing plate from moving outward away from its proper D, which needle plate for the purpose of this invention may be considered a fixture, after the manner shown in Fig. 3, making an engagement which acts as a separable hinge joint and about which the closing plate may be pivotally turned to an open or closed position. The said lip, of course, will assist in retaining the plate against any withdrawal in a directly upward position when it is once closed. Also on the under face of the plate we provide a catch strip E having laterally projecting wings E extending through notches in the ears B, the ends of which wings are turned at right angles to the plane of the plate and are shaped so as to form catches E designed to take under the above described lugs C which project from the base plate into the opening. This catch strip is held in place by means of the ears B and a headed rivet E passing through a suitably formed slot E therein. The catches are thrown forward by means of a coiled spring fitted in a socket piece E secured to the catch plate and bearing against a lip or shoulder B formed at the forward edge of the cross strip B. Said catch strip when in 11 its forward position projects slightly beyond the thumb notch referred to so that by the insertion of the finger into said notch the said catch strip may be moved back to the point where the catches clear the retaining lugs and permit the swinging of the plate upward. For the purpose of retaining the said plate in its uppermost position, we secure a finger F on the head of the machine in proper position to permit the forward edge of the catch strip E to snub under the same when the plate is raised to position shown in Figs. 1 and 2.

Should it be desired to attain access to the working parts while material is in the machine, especially should such material be too stifl' to permit the plate to be swung to its open position, it will be necessary to do no more than swing it partly open to about the position shown in Fig. 3, after the catches have been pushed back. It will thereupon be easy to pull the plate forward along the plane which it then occupies, since it is clearly removable from the needle plate without any further manipulation. This is a marked advantage, since it frequently happens that it is desirable to get at the bobbin or some other part of the machine in the midst of work, and it is not always convenient to remove that work from beneath the presser foot at the time. Vith our construction of plate, however, it will be seen that the opening may be cleared at any and all times, and our construction is such that ordinarily the plate may be kept in its proper position, swinging on its separable hinge to and from its closed position, without any necessity for taking it out of or fitting it back into its pro-per place.

Having thus described our invention, we claim:

1. A sewing machine comprising a base plate and a table, said plate and table having openings therein, said openings being adjacent to each other and affording access to parts of the machine beneath the said base plate, a single cover plate for the openings, an edge of the said openings in the base plate and table and an edge of the cover plate being in contact, the cover plate being fulcrumed on that part of the edge thereof which engages with the base plate, the cover plate being separable as an entirety from the base plate when the cover plate is raised slightly above its closed position.

2. A sewing machine comprising a base plate and a table, said plate and table having openings therein, said openings being adjacent to each other and affording access to parts of the machine beneath the said plate, a single cover plate for the openings, the rear edge of said cover plate being fulcrumed upon the rear edge of said openings,

the plate being separable as an entirety from the base plate when the cover is raised slightly above its closed position, means for normally retaining the cover in closed position, and means for holding the cover in wide open position.

3. A sewing machine comprising a base plate and a table, said plate and table having openings therein adjacent to the needle plate and affording access to certain parts of the machine beneath the base plate, a single cover plate for said opening adapted to be swung upward on one edge and drawn outwardly away from the opening when swung upward, means retaining the cover against direct upward movement and means retaining it against lateral movement away from the opening when it is lying in horizontal position.
