GEORGE A. HILL, or SANFORD, MAINE.

. ADJUSTABLE THRESHOLD-TRANSFER.

Application filed April 28, 1911.

To all whom it may concern Be it known that I, GEORGE A HILL, a citizen of the United States, residing at Sanford, in the county of York and State of Maine, have invented certain new and useful Improvements in Adjustable Threshold- Transfers, of which the following is a specification.

My invention relates to improvements in devices for marking or indicating the dimensions of thresholds, and has for its object the provision of a device adapted to measure a wide variety of widths of door openings, consisting in providing an adjustable cross bar with removable, and replaceable sections, and also in being capable of regulation to gage the configuration of the door jalnbs so that they may be ac curately placed in position, the door jamb gages consisting of arms'adjustably mounted in slots in the ends of the cross pieces,

one of said arms being adapted to engage the face of the jamb, and another to measure the depth of the door rabbet, when the dc vice is in use, the rabbet gage having a slot therein and a slotted bar adjustably secured thereto that is used to measure the length of the rabbet and the depth of the jamb.

My invention will be described in detail hereinafter and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of my improved threshold transfer showing it applied to a section of a door frame, the cross bar being in two sections, Fig. 2 a similar view show ing the cross bar consisting of three sections and the device adapted to measure wide doors, Fig. 3 a cross section of one ofthe cross bar sections, Fig. 4 is a side view of the cross bar in two sections, and Fig. 5 is a side view of the cross bar in three sections.

In the drawings similar reference characters will be used to designate corresponding parts in the several views.

The cross bar 1 shown in Figs. 1 and 4 consists of two sections; each section having a longitudinal slot 3 adjacent to one of its ends and the other end provided with a laterally extending strap 1 rigidly secured thereto by rivets or pins and bent to form hooks 5 opening toward one another and spaced from the bar. The edgesof the sections 2 are formed with notches or recesses Specification of Letters Patent.

6 equi-distant from their hooked ends to receive the hooks 5 in assembling or dismembering the sections 2. In assembling the sections the hooks 5 on their ends are placed in said notches or recesses 6 and the sections moved to produce the desired width of space or length of bar and then rigidly secured by the thumb screw 8 shown in Figs. 1 and 4. To dismember the bar the thumb screw 8 is loosened and the sections shoved lengthwise until the hooks 5 register with the notches orrecesses 6 when the sections will readily separate. The end of one or both sections 2 is provided with a bore 7 to receive a thumb screw 8 to hold the sections in adjusted positions it being apparent that the sections are capable of adjustment in length at any length between the combined length of the two sections and the length of a single section.

9, 9 indicates arms each having a threaded bolt 10 secured thereto that is mounted in one of the slots 3 of the bar 1 and 11 a thumb nut mounted on bolts 10 to hold the arms in position on the bar 1. Arms 9, 9 are provided with longitudinal slots 11;

12 indicates an arm having a longitudinal slot 13 and 14: a set screw mounted in slots 11 and 13 to hold the arms 9 and 12 in adjusted relationship. 15 indicates another arm having a screw bolt 16 secured thereto that is also mounted in slot 3 and has a thumb or wing nut thereon to hold it in position on the bar. Arm 15 has one corner cut away to form a recess 18 to receive the short end of arm 9 when the formation of the door frame is such as to require the moving of the arm forward and more or less within the outer straight line of the arm 15.

As shown in Fig. 1 my improved device is capable of adjustment to doors of different widths and when in use the arms 9 are placed in the rabbets of the door frame and the arms 12 adjusted thereon so as to measure the lengthof the rabbet and at the same time the width of thedoor j amb. The arms 15' are then adjusted so that they engage the faces of the jambs. All of the parts of the device being then securely fastened together the measurements of the door frame indicated thereby may be transferred to any place desired and as many times as found desirable so that all of the door frames in a building may be made identical in size with the least amount of measuring. 7

To provide for transferring the contour of door frames that are wider than are capable of measurement by the use of a cross bar consisting of'only two sections I propose using a lengthening section 19 having laterally extending straps 20 rigidly secured to its ends by rivets or pins-and bent to form hooks 21 opening toward one another and spaced from section 19. The middle of the section 19 is provided with. notches or re- Qcesses 22 in itsedges, the distance from the recesses 22 to either, end of .the section 19 being equal to the distance from. the notches or recesses'fi to the hooked ends of sections 2 so that when assembling the sections 2 with the lengthening section 19 first one and then the otherof-the sections 2 is slidably engaged with the section'19 forming an adjustable'bar of three sections. The straps V and ends of section 19 are provided with threaded openings 23 to receive thumb nuts 2 1 to hold the sections 2 and lengthening section'19 in adjusted positions.

25 indicates a threaded opening in the .middle of section 19 to receive thumb screw 26 when the three sections are mounted together. The purpose of :this thumb screw 261s to prevent the sections becoming accidentally dismembered which it does by being screwed down until the end of the threaded portion extends beneath the section 19 and prevents the hooked end of either of the sec- .tions 2 from registering or getting in aline ment with the notches in the center of the section 19;

When the lengthening sectionc19 is to be used in combination with sections 2 the arms :9and 15.0none of the sections 2 are reversed so .thatthe hooks 5 on both sections 2 extend upwardly. The lengthening section 19 is then mounted on sections 2, first on one andthen on the other, the thumb screw 26 is then screwed down, and when the bar has been adjusted to the desired width the sections are secured together by the thumb nuts 24 mounted on the ends of the lengthening section 19.

Having thus described my invention what I claim isc I 1. An adjustable threshold transfer bar having a longitudinal'slot adjacent each end :and consisting of sections adjustable one upon the other, a laterally extending strap oneach of sa1d sections, said straps being on V opposite sides of said sections when assembled and each of said straps bent to form hooks opening toward each otherand spaced from said sections,'and said sections being provided with-notches to receive such 9 of' said hooks asare on the'othersection, means for holding said sections in .an adjustable positiomla pair .of ammsr-ioneof said pair :of

arms being adj ustably secured through one of said end slots in said bar, and the other 111 the other of said slots, each of said arms having a recess in its end adjacent said bar, a second pair of armsone of said second pan .of arms being adjustably secured through rigidly secured thereon at each end and notches in its side edges and a thumb screw in its center, said straps beingbentto form hooks opening toward each other and spaced from said center section, said notches being opposite each other and equi-distant from said hooks, and said thumb screw being 'between said notches, said end sections each having a longitudinal slot at one end and a laterally extending strap rigidly secured thereon at the other end and notches in their edges, said last named straps being bent to form hooks opening toward each other and spaced from their respective sections and posltioned, to register with the notches in said center, andthe notches 1n said end SBCtlOIlS' so positioned as to register with said hooks on said center section when said. sections are being assembled to form said bar, gage arms mounted on the free ends of said end sections and means for securing said arms in adjusted positions, said thumb screw in said center section being adapted to prevent accidental separation of sa1d sections.

3. In an adjustable threshold transfer,

an adjustable bar consisting of sections con nected by laterally extending straps rigidly secured to the ends of said sections and hav ing their ends bent to form hooks, said sections having notches on their edges spaced to register. with said hooks when said sectlons are belng assembled ordismembered,

and means for securing said sections in an adjusted position, each end of said adjustable bar being provided with a longitudinal slot in which to secure gage arms.

4. In an adjustable threshold transfer, an adjustable bar consisting of a center section and two end sections, said center section having a laterally extending strap at each end, said straps being bentlto' form hooks,

thumb nuts in said straps, notches in the center of its edges equi-distant from said hooks and a thumb screw in its center between sald notches, said end sections each having a longitudinal slot at one end and a laterally extending strap at the other end and notches their edges, said ilfLSfi named straps being bent to form hooks and said last named notches so positioned as to register with said hooks on said center section when said sections are being assembled to form said bar, said thumb nuts in said straps on said center section being adapted to secure the sections in an adjusted position, and said thumb screw between said notches in said center section being adapted to prevent accidental separation of said sections.

In testimony whereof I hereto affix my signature in the presence of two witnesses.
