To all w/zom'z't may concern:

Be it known that I, DAVID F. YOUNG- BLOOD, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful DoorrOperat-ing Means, of which the following is a specification. I

The invention relates to improvements in.

mechanism for'operating jail doors.

The object of the presentinvention is to improve the construction of mechanism for operating jail doors, and to provide simple, strong and durable means of inexpensive construction, adapted to be easily operated with a single movement of the hand to open and close a plurality of doors simultaneously, and capable of permitting any of the doors to be disconnected from the operatin'g mechanism, so as to remain either open or closed while the other doors are simultaneously operated.

A further object of the invention is to provide door operating mechanism of this character, which will be entirely concealed from view, and which will indicate positively and clearly the positions of the doors,

- so that it will be impossible for a door to become disconnected from the operating means and accidentally left open or closed without the knowledge of the person operating the mechanism.

lVith these and other, objects in View, the invention consists in the constructionand novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that "various changes in the form, proportion, size and minor details of construction, with in the scope of the clain1s,.1nay be resorted to without departingfroni the spirit or sacrificing any of the advantages of the invention. r

,Like numerals of reference designate corresponding parts'in all the figures of the drawings.

In the accompanying drawings'in which is illustrated the preferred-form ofthe in: vention, 1 designates a front. wall of a row or series of cells 2. Only two of the row or series of cells are illustrated in the drawings, but; it will be clear that the row or series may. consist of any desired number, and that the door operating and locking mechanism may be'con'structed to suit the requirements of the jail in which it is to be used. The front wall is provided at each cell with a door opening 3 and is equipped with a slidable door 4, hung" from a track 5, which is located within a longitndinal top casing 6 provided at the front with a depending box or extension 7 and containin the mechanism for actuating the doors an for o crating the locking means. Each door 4 w iich is designed to be constructed of sheet -metal or other suitable material, is provided at its front edge with inner and outer vertical grooves 8 and 9, and it has correspondinginner and outer vertical grooves 10 and ll.- at its rear edge. I he "front and rear grooves are preferably formed by metallic strips, suitably secured to the inner face of the door, the metallic strip at the rear edge of the door being also angularly cent to provide aproiecting transverse 12, adapted to conceal a' vertical locking bar 13 from the rear when the dooris closed. The c tron. 9 receives a vertical flange id of a flanged member 15, suitably sec .red to the flOIll? wall at the door opening. The flanged member if a ranged in the door oi mg and is angel y bent at its lower p to provide an attaching flange 16, which projects in theopposite direction from the flange 14. The attaching flange is secured -to the inner face of the front wall of the cell by rivets or other suitable fastening means, which also pierce an outer vertical strip 17. The wall is equipped at the rear side of the doorv opening with a. flanged member 18, having an inner attaching flange 19 and provided at its outer portion with oppositely projecting flanges 20 and 21, extending forwardly and rearwardly and adapted to engage, respectively, the inner front groove 8 when the door is open and the inner rear groove. 10 when the door is closed. The front wall of the cell is also equipped with a flanged strip ormember 22, having an inner attaching flange and an outer projecting flange, whlch extends into the rear outer groove 11 of the door when the latter is open. The vertical grooves and the flanges interlock the door with the front wall of the cell and hold the door against outward movement and enable the door to resist lateral 'pressure in either direction.

' The door is provided at'the top with an extension 23, projecting upwardly through a slot or opening 24 in the bottom of the to be equipped with flanged strips 26*, ar

ranged to project beyond the door for covering that portion of the slot or opening- 24' unoccupied by the door in order to prevent any article or substance from'being introduced 1nto the caslng and interfering with the free operation of the mechanism for actuating and locking the doors. The

' flanged strips 26, which are preferably in- 7 door actuating bar 30, consistmg of a hori 6O verted 'T-shaped' in cross section, consist of a vertical web and bottom flanges, the web being arranged in the vertical plane of the door and riveted or otherwise secured to the horizontal bar ..or piece 25. V The door is provided at the bottom with a groove 27 into which projects a fixed guide 28, preferably consisting of spaced lugs having intervening recesses 29 'and adapted to permit dirt and other trash to be readily swept past the guide. v

Each slidable door is equipped with a zontal body portion, arranged within the top casing and rigidly secured at its rear end 31 to the hanger 25 and provided at its. front end with a depending arm 32, arrangedin avertical position and extending into the box 7. The frontportion of the door actuating bar issupported in a guide, consisting of spaced upper and lower grooved rollers or wheels 33, mounted on a suitable support 34and receiving the upper and lower edges of the door actuating bar and permitting the same to slide freely in opening andclosing shank 35 bya-projection or pin 37, secured to the reduced portion or shank and projecting into a spirally arranged slot 38 of the coupling sleeve.- The coupling sleeve forms a housing for a coiled spring 39,1engaging the reduced port-ion orshank of the door actuating bar and the lower closed end of the sleeve and adapted to cause the same, when rotated, to spring downwardly into engagement witha traveler 40. The traveler 40, which'is disposed transversely of the top casing 6, is provided with a slot 41, and the lower closed ends of the coupling sleeves of the door actuating barsare reduced to .pro-' vide projections 42 for engaging in the slot 41, whereby the door actuating bars are coupled-or connected to the traveler for enabling a plurality of doors to .be operated in'unison 1n opening and closing the same.

The spiral slots .38 of the coupling sleeves have sufliciently low pitch to retain the sleeves in an elevated position and to prevent the sleeves from being rotated by the coiled springs-39. By means of the vertically movable coughing sleeves a plurality of door actuating bars may be connected to the traveler for simultaneous operation, and any number or combination of doors of a series may be thus operated while the other doors of such series are left in either an opened or a closed position.

The traveler rtO'ls-provided at its ends vith curved arms 43, having terminal journals upon which are mounted rollers or wheels 44, arranged to run on guidingtracks 45. The guiding tracks 45, which project horizontally from the opposite walls of the bar or extension of the top casing, consist of rack bars and are provided at their lower faces with teeth 46, which mesh with gears 47, mounted on a horizontal shaft 481carried by. the traveler. The shaft 48 is arranged ios in openings 49 of approximately bearing brackets- 50, securedl-to the traveler at the end port-ions "thereof and depending from the same, as clearly shown in Fig. 9 of the drawings- The traveler is equipped with a centrallyr'arranged handle 51, having a hear: ing opening 52 and constituting a central. bearing and support for the shaft 48, and

adapted to be grasped by the operator to reciprocate the traveler. The traveler is slidably supported by the tracks, the upper rollers or wheels forming anti-friction devices and the gears causing a uniform movement of the traveler, so that both ends,

of the t-ravel'er'will move atuniform speed and the traveler will be prevented from vtwisting from its true position, and the slidable doors will be actuated the same distance, wherebyfa full opening and closing movement of all the doors connected-with the traveler may be secured;

Each of the doors is also provided at the,

top with a projecting portion 53 of a length less than the width of the door, and forming front and rear shoulders 54 and 55, adapted to be engaged by'a stud 56 of a bell crank or rocker member 57 The bell crank orrocker member .57,- which is a proximately triangu lar, is mounted on-a xed pivot 58,1ocated at the lower portion of the bell crank and at a point intermediate of the lower angles thereof. The pivot 58 issuitably mounted on the inner or rear wall of the box or casing, and the stud 56, which is located in advance of the pivot, is adapted to engage the rear shoulder 55 for locking the top of the casing when the latter is closed, and the said stud 56 is also adapted'to engage the front shoulder 54: for locking the top of the door when the latter is open. The bell crank or rocker member isconnected at its lowerrear angle to the vertically movable locking bar 13 by aisuitable pivot-59. The

lower end of the locking bar 13 is provided with a horizontally projecting lug 60,adapted to engage front and rear recesses 61 and 62 of the door. for locking the bottom thereof, when the door is in its opened and closed position. The locking bar is located in rear of the rear flanged member 18, and fit "extends from the top casin to the bottom of the door and it is actuate by the bell crank or rocker member for carrying-the top stud 56 and the lower lug 6O simultaneously into and out of engagement with the top andbottom of the door. As the stu 56 and the lug 6O engage, respectively, th I top shoulders and the lower recesses of the door, the latterflwill haveto be either in-tan openor closed position in order to operate the looking mechanism, which is adapted, tosfsecure the door either in its open or closed position.

The bell cranks or rocker members are connected at their upper anglesby suitable pivots 63 to the rear, ends of thehorizontal connectingbars fiftf iextending forwardly to anope'rating or master lever 65, fulcrumed atlan intermediate point on asui'tablefpivot 66"a11d provided with a plurality of. upper slots 67, adapted "to receive the front ends of the connecting bars 64. The-connecting bars 64 are provided at theirlower edges with notches 68, adapted to be engaged by bolts 69 of catches, mounted on theoperatingjle; ver 65 for-detachably couplin the' front' ends of the connecting :bars to t e operating lever. Each bolt 69 is actuated bya s ring and is connected at its lower end with a lever and ther unauthorized persons.

'79, pivoted at its inner end to a flange 80 of the master or operating lever 65 by a pin 81,

or other suitable fastening device and ex.

tending through a lower longitudinal slot 82 in the said master or operating lever 65.

The bolt actuating lever, which is provided with a grip, or handle, is adapted to be swung upwardly and; downwardly in the slot 82. The slot 82 is provided at its lower engagement with the door or doors, and it is secured in such position by a spring actuated detent 71, mounted on the operating or master lever and arranged to engage a toothed or notched bar orsegment 7 2, suitably secured to the rear wall of the box or extension 7 of the top casing.

actuated dog or detent is operated by a latch The spring lever in the ordinary manner, and it is adaptedto lock the lever in its adjustment.

The box or casing may be equipped with a 7 suitable door, or the operating means may be otherwise made inaccessible to-prisoners AS. the

door actuating bars and the connecting bars extend \iirectly from the'actuating means to the doors and the bell crank or rocker members, there is no lost motionand asimple" constructiongnot liable to get out of operation is provided. The position of the parts within the boxor extension will afl'ord infallible means for indicating the positions of thevarious doors in the series, so that there is no liability of any one of the doors of a series being accidentally left in the wrong position if the operator is careful. The

locking mechanism of any of the doors of the series may be disconnected from the operating lever, so that trustiespr other per sons may open and close the disconnected doors at will; A

No claim is made in the present applica: tion to the locking mechanism.
