SHUTTER- WORKER.

SPECIFICATION formmg' part of Letters P atent No. 657,448, dated Se tember 4, 1900.

Applic ation filed July 2,1900. Seria1No.2Z,314. (No model.)

To aZZ whom it may concern.-

Be it known that I, SAMUEL L.,POWELL, a" citizen of the United States, residing at New? berry, in the eountyof Newberryand State of South Carolina, have invented a certain new and usefullmprovementin Shutter-Workers, of which the following is afull, clear, and exact description.

This invention relates to that class of shutter-operating mechanisms by which outside shutters or blinds which are hinged to the window casings or frames may be opened and closed and locked in either or any intermediate position by operation of mechanism within the building and without opening the windows.

The inventioncomprises a band-and-pulley mechanism arranged inpart within the build-. ing and upon the windowsill or casing or frame and cooperating with an arm having a. peculiar sliding connection with the shutter for unlocking and opening it and for closing and looking it and for retaining it in any in termediate positions, all as Iwill proceed now to set forth and finally claim.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure l' is a vertical section of part of a window frame with my shutter-worker and .part of the shutter in elevation. Fig. 2 is a top plan view of the inside operating mechanism. Fig. 3 is a front elevation, with parts broken away, of the mechanism shown in. Fig. 2. Fig. 4 is a perspective view of. the lockingdog. Fig. 5 is a perspective view of theshnt ter mechanism and part of the arm. Fig. 6 is a vertical section. of the outside pulley. Fig. 7 is a top plan view of the stand for the pulley of Fig. 6. Fig. Sis a vertical section of a modified form of sprocket-wheel which may be substituted for the pulley of Fig. 6. Fig. 9 is a perspective view of a modified form of shutter-fastener.

The window-sill a and the frame or casing b may be of usual construction. On thefacing 0 is secured, as by screws, a stand d, having a stud-shaft 6, upon which is'mounted to revolve a pulley or wheel f, adapted toreceive a cord, rope, band, or chain g, which may be made fast thereto bya pin or pins 72. This pulley or wheel f is provided with a depending handle 11 for rotating it. The stand d is provided with bearingears j, in which are mounted the guide-pulleys k on axes at right angles to the axis of the said pulley or wheel f, and the cord or other connector g passes over these guide-pulleys The pulley or wheel f is made or provided with rackteeth Z on its rim, and adog m is pivoted at 'm to the stand d and has a tooth m which is adapted to engage with the rack Z to hold the pulley or wheel f in any desired position, and said dog is also provided with a knob or handle m by which itstoothmay be released from engagement with the rack-teeth Z, the said dog otherwise operating by gravity.

Upon the sill a is mounted a pulley to receive the cord g and to transmit motion to the shutter-operating arm, as I will now proceed to describe. provide a stand n, (see Figs. 6 and 7 especially for details,) which may be screwed to the sill and is provided with a stud-shaft it, upon which turns the pulley 0, and this pul- In one form of my invention I ley receives the cord g. The stand it may have a vertical flange 11, to inclose the perinr eter of the pulley 0, or it may bemade without said flange, as indicated in Fig. 8. The pulley or wheel 0 has a grooved or otherwiseconstructed perimeter to receive the said cord, band, or chain, or it or the wheel, or

bothof them, may be made as sprocketwheels, as indicated in Fig. 8. From the face of the pulley or wheel 0 project forked bearings 99 and q, the former being adapted to have pivotally connected therewith and in an adjustable manner the shutter-operating arm 1", while the forked bearing is of sufficient height to serve as a guide and stay for the said operating-arm in its movement to open and close the shutter. As 'shown in Fig. 6, if the flange n be employed the pulley or wheel 0 may be rabbetedto overhang said flange, so as to exclude moisture and dust from entrance between the stand and the wheel. The arm r has a number of transverse openings r to receive the pin W, by which it is pivoted to the bearing 19. The

outer end of the arm r is curved at r and forked at r and provided with a roller W. This forked end of the arm straddles a rail s, which is made fast to the shutter horizontally thereof in any suitable way, and its outer end has the crook s for a purpose presently appearing. A strip of metal t is atrangedupon the shutter parallel withthe rail 8 to form a runway or wear-plate for the roller'r and at the end of this strip Us a double inclined lug u, arranged adjacent to projecting member v, which extends intothe path of movement of the roller r and a'dja- 1" cent to thelug u, lNow when the wheel) is rotated and the wheeljo is also'rotated there by the arm ris swung inwardly or outwardly V to move the shutter. Suppose that the shutter is closed and locked by, the fastener v.

The first impulseof [the movement causes, a

depression of the roller and of thearm against the extension vof the fastener, so as to re lease the'fastener from itsengagement with I the stationary part thereof onthewindow-sill,

and then the said rollerv mounts the lug u andbearsagainst the strip and pushes open the shutter to the desired fextent. If itbe de sired to 'only'p'artlyo'pen the shutter and to hold itinsuch position," the dog 'm'is caused to engage with theIrack-te eth Z, andthis, is true 'of any intermediate position betweenfiilly opened and .fully closed, and it is also obs vious that the shutter may be locked in fully opened ,positionxbythe, same means. 7 The crooks 'aftords'ithe necessary room for the play of the bent end of the shutter-operating army for unlocking the shutter-fastener and in traveling from it overthe -l'ugu and ,upon

the'striprt.

'- As shown in Fig; 5, the rail 8 has independ ent fastenings ateaoh end; but, as shown'in v Fig. 9,"the plate w of the shutter fast'enerx may be made with the lugs w w to serve the double purpose of lugs as such and for either rlght or left hand operation and to receive the outer endof' the rails, holes to being proi videdin the'selugs for this purpose.

It has been already mentioned thatthe connecting device 9 may be secured to the pulley f by pins h, and a similar pin h rmay I be used to connect it with the pulley 0.

. One veryimportant feature of the present invention is that the parts may be secured in The shutter-fas position without any othercutting thanholes for the passage of the connecting device g from one wheel to the other-that is to say,

the shutter is. required for the application of the parts of myinvention.

What I claim is- 1. A shutter-worker, comprising a stand, a pulley m'o'untedthereon, means to rotate said pulley, guide pulleys mounted upon said stand and at right angles to the axis of the vmain pulley first mentioned, an outside pulley, a cord, chain-, or band connecting the two pulleys, and an arm pivoted to the outside pulley and adapted to be movably connected with the shutter, substantially as described. a 2. A shutter-worker, comprising a stand, a pulley mounted thereon, means to rotate said pulley, guide pulleys mounted upon said stand and-atright angles to theaxisof the main pulley first mentioned, an outside, pulley, having upwardlyrprojecting'torked bearings, an arm pivoted 'inone of said bearings "an dzguide'd by the other andadapted to be conmittin'g connector engaging the pulleys, substantiallyasdescribed; H a L 1 3.1 A stand, a "ulleyfrnounted thereon and provided with rack-teeth, adogfor engaging said teeth, means to'rotate said'pulley, and guide-pulleysflarranged onthe-stand, combined with a stand having anupright flange, a pulley mounted up'o'n'said stand within said. flange, a cord, chain, or band for'connec'ting said pulleys, and a-shutter-operating arm pivoted to thelincasedpulley, substantially as described}. J '7 4; The combination .with a shutter-worker havinga swinging arm, of a shutter-fastener "having a plate provided with oppositely-am ranged inclined lugs to cooperate with said swinging arm and adapted for useon right or left hand sh utters, substantially as'described. In testimony whereof I have hereunto set my hand this 16th day'of June, A. D. 1900.
