NEEDLE-GUARD FOR SEWING-MCHINES.

T o all whom it may concern.'

Be it known that we, AUGUSTUS LAvoIE, a citizen of the United States, and CvRILLn DEMERS, a subject of the King of Great Britain, both residing at Leominster, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Needle-Guards vif'or Sewing-Machines, of which the following is a specification.

Our invention relates to needle guards for sewing machines and particularly to'a guard which will prevent the operators of power driven sewing machines infactories and the like from pricking theirfingers.

AThe object of the invention is to provide a device of this nature, Which will protect the point of a needle and at the same time allow an unobstructed view of the needle at'all times. A further object is-to provide a device of this character which will allow the needle to be readily threaded without removing the device or altering its position in anyway.

An important object is to provide a' device of this character, which may be attached to the presser foot of a machine by means of the ,'screw always found` upon the presser foot, and which requires no further means for holding it in position. i

^` Another object is .to provide a guard Vwhich may be easily vertically adjusted to suit the length of the stroke of the needle bar. i

A still further object is to provide a device 'of this character which is inexpensive in its manufacture, durable, etlicient in service, and easilyapplied.

(.)ther objects and advantages will he made apparent inthe course of the following specification.

Referring to the drawings in which likev numerals are employed to designate corresponding parts throughout the several views: Figure 1 is a perspective view of our device applied to the presser foot of a sewing machine, Fig. 2 is a side elevation of the guard detached, Fig. 3 is a sectional view on the line 3-3 of Fig. l, and, Fig. 4 is an cndview of the guard detached.

Referring more particularly to the drawings, the numeral 1 designates the head of a sewing machine, in which is mounted the presser bar 2 and the needle bar 3. Secured upon the lower end of the har 2, by means of the Screw 4. is a presscreot 5 of the usual construction. A needle 6 is held in the needle bar 3 by means of the screw 7 as is customary.

Our device as a Whole is designated by the numeral 8 and comprises a horizontal plate 9 having a recess l0 in one of its side edges Within which the needle 6 is adapted to reciprocate. Formed integrally withthe horizontal plate 9 is an upstanding ear 11 provided with a sl'ot l2. Formed upen the lower surface' of the horizontal plate 9 or connected therewith, as by means of solder or the like, is an open frame-Work 13, which comprises a pair of Ushaped members la.

In use our device is attached to the presser .bar by loose-ning the screw et, placing the guard in position over the presser foot with ,the slot 12 registering with the screw 4, vmovmof the device up-or down as far as 1s desire then tightening the screw 4. It will be noted that by means of the slot4 l2, the guard maybe adjusted vertically .with the utmost ease to regulate the device for a long or short stroke of the needle (i, so that the needle will not rise above the` top edge of the horizontal plate 9 of the guard. It will be observed that the frame-work 13 allows arperfectJ- view ofthe needle at all times, offers no obstruction to threading it, and yet will not allow the fingers of the operator to be inserted within the path of travel of the needle.

It will be observed that the recess 10 in the horizontalplate 9 of the guard extends entirely to one edge, thus facilitating they changing of needles. As the point of the needle does not rise beyond the top of the guard, it would be ditiicult and awkward to `change needles unless this cut-out portion extended to the edge, thus preventing the needle :t'rom catching against the side of the opening during removal.

llaving thus described our invention we claim is:

l. In combination with a sewing machine, a needle guard detachably and adjustably. connected with the presser foot, said guard comprising a horizontal plate provided with a recessfinone of its side edges t'o-r the passage. of the needle, and an open framewhat work connected with said horizontal plate said guard comprising a horizontal platev provided with an opening for thepassage oli the needle, an ear provided with a slot s for engagement, with a screw upon the presser' foot, and an open framework secured upon the lower side of said horizontal plate, said framework comprising 'a pair of U-shaped members spaced laterally from the needle and extending longitudinally, said framework permitting absolute visibility of the needle, said needle beingadapted to have its point disposed below and its eye above said horizontal plate when in its lhighest position.

' 3. ln combination with a sewing machine,

'a needle guard adjustably and detachably `Aconnected with the presser foot, said guard comprising a horizontal plate provided with a recess in one of its side edges7 an attach-- ing ear, and an open frame secured upon the lower side of said horizontal plate, said $guard permitting absolute visibility of the Lamaze need-le'at all points, 'saidneedle having its eye disposed above and its point; below said horizontal portion when 1n its highest position, for facilitating threading, and said recess facilitating the changing of needles without detaching the guard.

4. A yneedle guard consisting of ahorizontal plate upturned at one end Afor attaching it to the presser foot rodof a sewing machine, and recessed on one side adjacent the other end to permit of Vthe needle point passing below sid plate, and downwardly extending ops secured to the under-side of said plate to prevent the oper# ators lingers coming in 'contact withv the` point of the needle.
