Specification of Letters Patent.

Application filed April 10, 1909. SerialNo. 489,220.

To all tuhom it may concern:

and MAxlMAanrs, subjects of the Czar of Russia, residing, at thecity and district'of Montreal, in the Province. of Quebec, Ganada, have invented certain new and useful Improvements in' Sewing-Machine Belt- Guards; and we do hereby declare-that-the following is a full, clear, and exact descri tion of the invention, such as will sn b e others skilled in the art to..-vvhich it apper- The invention to be hereinafter described relates to sewing machine attachments, and particularly to a guard for the belt and uley mechanism and the. bobbin win ing In large cloth cutting and tailoring establishments, where a-great number of'sew- A ing machines are em loyed, the machines are arranged close toget er and'in rows, so that the work-may be passed'from one machine stages; With a great number of machines running at high speed and pla'cedclose to gether, there is great danger of cloth being caught and cut or torn by the driving belt and adjacent mechanism of-the machine.

are very frequent in'large establishments,

driving belt, driving pulley and bobbinwinding mechanism n such manner as toprevent contact therewith. Such a housing or guard, however, in order to be pract1ca tion, reference should be had to the accomchines 'arei arra 'this' purpose, an inwardly panying drawings forming part of the present application. I

Throughout the several figures of the drawings, like reference characters designate the same arts.

In the rawings: Figure 1 is aside elevation of the invention in operative position, showing its application; F1 2 is a perspective of the invention, detac ed Fig. 3 1s a perspective of the catch for holding the device in operative osition; Fig. 4 1s a viewv similar to Fig.1, ut broken away to show the catch 11 and 006 crating toe 10; and,

'Fig. 5 is aside elevation of'a machine with theflanged plate swun to inoperative position, giving an inside plan view of the same.

In the drawin s, the invention has been shown as applie to a well known t pe of tailors sewing machine 1. This mac he is Patented July 26, ieio.

driven b 0 8'. belt 2, which passes over a friction p' cf :5 3 on the end of the usual operatingsha chines-are used in. ar e numbers by all largetailoring and'cloth cutting establishments. In such-establishments, these ma so that work may. epassed from one oper- ,at'or to another. at adjacent machines during successive'stages of the tailoring. operation. As 'the cloth. is handed from one operator to another, it is' verylikely to touch either- ;thebelt 2 or pulley 3, becoming caught or .85

tom thereby, or else becoming so entangled as to require stoppage of the machine for- At the resenttime, such maed "very close together,-

disentanglement or ,repairs, or both. To I vprevent such possiblercontact, ahood has een provided. This hood comprises a face plate t anda broad peripheral flange 5 extending substantially erpendicularly therefrom. The-hood is a a ted to. be pivotally supported on the table card 8 of the mach1ne,and'to that end is provided with an integrally formed perforate, ear 6, through which ma be passed a screw or other pivot '7. In or er to allow the hood to fit up as closely as dpossible to the belt 2 and pulley 3, the hoo is formed with a notch or opening 9, through which the spindle for-the be bin winding mechanism and thebracket for sup orting the same may project, as,

the hoo is swung into'operative position, as shown in Figs; 1 and 4. When the hood has been swung to operative position, it is necessary, of course, to fasten it so. For rojecting toe 10 has been formed on the ower forward tion of the several parts of the invention,

' presented is, "however, left open for cone.

Having thus fully described our inven- 40 chine having a belt-pulley and riving belt, a hood pivoted to turn horizontally the hood, constructed according to the above pecia-lly designed to cover and protect the secure by Letters Patent, is

edge of the flange 5, and is adapted to be engaged by a catch 11 pivoted to the table board 8.

On referring to Fig. 1, it will be seen that description, completely incloses the belt .2 and its friction pulley 3, while at the same time leaving the hand wheel completely uncovered and accessible to the operator at,

all times. Thus, it is absolutely impossible for cloth to become injured by the belt or friction pulley as the cloth is passed from one machine to'another;

It is clear that changes may be made in the construction, arrangement and disposiwithout in any way departin from the field and sco e of the same, an it is meant to include a 1 such Within this application, wherein only a preferred form has been 'shown.

' We are aware that pivoted housings or guards have been employed to cover at-will some parts of a sewing" machine and we do not broadly claim such a guard. It will be observed that our hood is eselt, pulley and proximate parts at front, top and near thebelt and especially to protect the cloth from inju thereby as it is v assed to the machine. T e side of, the housing away from that to which the cloth is veni'entaccess to the belt and other parts, no guard for the-cloth being needed on that side. f "The hood iseasily turned horizontally into' operative positionand the locking by the pivoted catch is immediate and secure.
