7 I MP3RQHVEMENT IN SE WlhIG-MACH rNES.

Specification forming part of Letters Patent No. 39,442. dat d August4, 1863.

To all whom it may concern:

Be it known that we, JAMES A. HOUSE and HENRY A. HOUSE, both of Brooklyn, in the county of Kings and State of'Ne w York, have invented certain new and useful Im provenfents in Sewing-Machines, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings,which make part of-this specification, and in which- Figure 1 represents a view in'perspective of a machine for working button-holes, embracing ourimprovements, with its parts in position for operation; Fig. 2, a plan or top view of the same with its upper casing removed; and Fi 3, a view in elevation ofone side of the same, the casing and a portion of the mechanism being shown in section and the presser-levcr raised, in order to permit the removal or adjustment of the work.

The improvements claimed under this patent consist, first, in making the frame or casing of asewing-machine in sections, so constructed and connected thatthe parts of thecasing may readily be separated and the mechanism within it removed, and yet when the portions or sections are united the mechanism shall be inclosed and protected from dust and meddling or tampering with it prevented; secondly, in mounting one of the guides by which the movements of the frame which carries the stitching mechanism are controlled upon one section of the casingofa sewing-machine, while the other guide and the gage which determines the size of the button -hole to be worked are secured upon the other section, which arrangement renders the mechanism more compact, and also facilitates its removal from the casing; thirdly, in mounting the stitching mechanism ofa sewiug-m'achinein a frame which traverses upon the main framing or casing, is inclosed within stitching mechanism is traversed in an open bracket upon the casing, by which means the operator is enabled to remove the mechanism from the casing by simply lifting it from its bedwithout removing screws, bolts, or other .fastenings. 1

In order-to carry out the objects of our invention, we mount the driving-gearing and stitching, mechanism of the machine in a stoutframe and incl-ose it in a tight casing to exclude dust and other matters and to prevent meddling with the machinery. In order to obtain access to the mechanism when desired, we divide the casing horizontally into two. sections, the adjacent edges of which fit closely'together. The frame which contains the gearing slides on waysin the casing, being traversed back and forth by a screw actuated by the driving-gear. This screw works in anut mountedin an open boxer bearing on the casing, so that the frame can be removed at any time by simply removing' the upper casing and lifting out the frame containing the mechanism. The two sections any device which will admit of their being readily connected and disconnected.

The accompanying drawings exemplify one mode of carrying out the objects of our invention. In this instance the casing or framing of the machine is shown as consisting of two tight cast-iron sections, A A, placed one upon the other, and with their adjac'ent edges made to fit each other accurately. Teuons a upon the ends of the upper section take into corresponding slots or mortises' on the lower one and hold the two firmly together. The stitching-mechanism and geariu g are mounted in a strong frame, D, which slides on ways d on the lower section, A, of the casing. This frame is caused to traverse back and forth at works in a nut, 0, having a female screw cut in it. This nut fits accurately edgewise between vertical staudards 49, mounted on a horizontal bracket, E, projecting from the lower casing, A, by which arrangement the frame D, as well as the entire gearing and mechanism, can be removed from the casing by simply lifting the screw out of its bearings, whileit is held perfectly secure until so lifted. The traversing-screw E is rotated by means of a may be locked together for greater security by' proper intervals by means of a screw, E, which bevel-wheel, 0 upon itsend, which alternately engages with two bevel half-gears, f f, on a sliding collar, F, which moves freely on the driving-shaft G, which is mounted in the sliding frame D. A slot, g, Fig.1, is made in one side of the casing topermit this shaft to travel with the frame. A fixed stop or detent, M, is secured upon one end of the lower casing, A,

A detailed description of the construction and operation of the other portions of the mechanism is deemed unnecessary. here, as they are shown and described in three other applications for Letters Patent filed by us simultaneously with this, and respectively marked divisions B, O, and DJ The inventions claimed under this patent are applicable to other sewing-machines, but are more especially designed as improvements upon a sewing-machine for which Letters Patent were granted to A. G. Seaman and ourselves-(as our assignees) November 11, 1862, which patent contains a full description of the operation of our machine and of the stitch formed by it.

It is obvious that the details or our arrangements mightbe varied in many ways without departing from are spirit ofourinventiomwhich modifications would readily suggestthemselves to a-skillfnl mechanic after seeing our invention.

Wha't we claim under this patent as our ll] vention islfMaking the casing oil a sewing-machine in sections, so constructed are; counectedthatthey may readily be separate and the mechanism removed, and yet when the sections are united the mechanism shall be inclosed and protected,snbstantially in the manner described.

2. Mouuting oneof the guides by whichthe movements of the frame which carries the'stitchin g mechanism are controlled upon one section of the casing of a sewingmachine, while thefother guide and the adj usting-gage are mounted upon the other section, substantially in the manner described.

3. Mounting the stitching mechanism of a sewing-machine in a frame which traverses upon the main framingv or casing, is inclosed within it, and which can, readily be'detached therefrom, substantially in the manner dc scribed. I

4. The combination, in a sewing-machine, of a traveling frame which carries the stitching mechanism and gearing with'a traversing screw mounted upon one end of the frame and acting upon a fixed point on the casing, substantially in the manner described, for the purpose of traversing the frame, as set forth.

5. Mounting the nut of the traversing-screw by which" the frame carrying the, stitching mechanism is traversed in an open bracket upon the casing, substantially in the manner described, for the purpose of readily detaching and removing the traversing frame, stitching mechanism, and gearing, as set forth.

In-testimony whereof we have hereunto subscribed 6ur names.
