CABLE-GUIDE FOR DROPHEAD-SEWING-MACHINE CABINETS.

To MZ whom t may concern:

lie it known that l. Tnnonon Kenora, a citizen of the United States, residing at inhewoml, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Cable-Guides for Drophead- Sewing-Machine Cabinets, of which the following` is a full, clear, and exact description.

This invention relates to the kind of drop head sewing machine cabinets in which there is a head supporting platform that is hinged on a horizontal transverse axis to the top or table of said cabinet,. and is adapted to. occupy either a horizontal working position in an opening through said table.I or downwardly inclined position below .said table, and an extension top that is pivoted to the table on a horizontal axis at right angles to the axisof the platform, and Ya flexible cable which connects the hinged ijflatforni with the hinged extension top, Jvhcreby the latter :is it swings from its closed to its open position will swing` the platforn'i up into its horizontal working position and hold it there.

rlhe present invention has to do with the cable guiding means which must be provided for the cable to engage with as the platform is raised or lowered by swinging the extension top.

rhe object of the invention is to provide a cheaper cable guide than any heretofore used.

The invention consists in the cable guide and the combination of the same with the table as shown in the drawing and hereinafter described and pointed out delinitehY in the appended claims.

In the drawing Figure 1 is a plan view of a sewing machine cabinet equipped with the present invention and shows the relation of the parts when the hinged platform is in the working position. Fig. 2 is a front view of the saine mechanism in the same relative position; Fig. 3 is a rear elevation partly sectioned of enough of the table top and hinged extension top and cable guides to show their relative position; Fig. l is a perspective view of the cable guide; Fig. 5 is a vertical sectional view in. the plane of line 5 5 on Fig. 3.

Referring to the parts by reference characters, 10 represents the table or top of the Specification of Letters Patent.

cabinet having an opening l()a through it; 12 represents a rectangular frame secured to the top of the table around said opening; 14 represents the extension top which is suitably hinged to the left end, of said. frame; 15 represents the head supporting platform which is hinged near its front edge to the side members of the frame 12 by means of alined pintle pins 17. This platform has a flap 16 hinged to its rear edge; as is the usual practice, so that said plat-- form and flap when they are in horizontal working position will substantially lill the openings in said frame. A bracket or arm 19 is fixed to the platform and extends a suitable distance rearward.

20 represents a flexible wire cable which at one end is secured to the rear edge of the extensiontop by means of a pin 21 located a suitable distance from the axis of the hinge of said extension top. The cable then passes down through the table top; and its other end is secured to said arm 19. All of the foregoing is conventional construction, and is well known in a great variety of specific forms.

The cable guide 25 to which this invention particularly relates is shown detached from the table in Fig. Il. It is made of a single piece of wood of some wear resisting kind, as for example, hickory. It includes a base 25a and an upwardly iextended substantially rectangular body 25b which passes through and fits in a hole 10J in the table, and when it occupies this position the base 25a engages the bottom of the table to which it is secured by two or more screws passing upward through said base.

The rear face of the block extending from the top to the bottom thereof, is a curved recess 25, which provides a curved surface 25(1 with which the cable will engage. The

lower edge 25e of the bottom of this recess is also curved substantially as shown in order that the cable may engage and 'be guided by it.

Vhen the extension top 14 is swung from its closed position shown in Fig. 3 to the open position shown in Figs. 1 and 2, it draws the cable up. This cable slides in contact with the curved surface 25d as it passes through the table, and it likewise slides over the curved surface 25 as it proceeds from arm 19 to said cable guideway.

shown, has less injurious effects upon theV cable than have the sheave and rollers which have commonly been used heretofore toguide the cable; and it has also been found that this wood cable guide is suliiciently durable to last substantially as long as the other mechanism would last. In case, however, it does wear out it is easilyvreplaced and at very slight expense.

Having described my invention, I claim:

l. In a drop head sewing machine table of the class described, the combination of a table top having a hole through it, with a cable guide comprising a wood block having an upwardly extended body which passes through and fills the hole in said table top, and having an enlarged base portion which engages with and is fixed to the lower surface of said'table top, said block having in one of its vertical edges a curved cable guide groove which extends from the top to the bottom of said body.

2. In a drop head sewing machine table o the class described, the combination of table top having a hole through it, with a cable guide comprising a wood block having an upwardly extended body which passes through and fills the hole inthe table top, and having also an enlarged base portion which engages with and is iixed to the lower surface of said table top,-said block having in one of its vertical faces a curved cable guide groove which extends from the top to the bottom of said body, and having the lower edge of that part of the body which forms the bottom of said guide groove curved downwardly and away from the surface in which said guiding groove is formed.

In testimony whereof I hereunto aliX my signature.

THEODOR KUNDTZ.
