LIGHTER Filed March 5, 1948 INVENTOR. Ja /J1 J $955144 Patented May 30, 1950 NI-rep STATES 2,509,941: LIGHTER Louis Sl sabbia, Brooklyn; Application March 5, 1948, Serial No..1'3;160

My invention relates to improvements in lighters and more particularly, has reference to means associated with a gas burner, such as for a Bunsen flame employed in dental operations, usually adjacent the operating chair and is intended to ignite the gas without the use of matches.

In the accompanying drawings, I have illustrated a suitable application of my invention as associated with the work tray or table, generally pivotally mounted. in adjustable relation to the chair. Referring thereto, Fig. 1 illustrates the same in perspective, parts being broken away. Fig. 2 is an enlarged sectional elevation of the burner, guard or work holder and a side view of the lighter, on the line Z-2 of Fig. 1. Fig. 3 is a perspective view of the lighter, as a removable attachment, adapted for right or left-handed use and for clockwise and counterclockwise operation. Fig. 4 is an enlarged sectional elevation of the same on the line 44 of Fig. 3. Fig. 5, is a side elevation of a preferred form of replaceable flint-wheel. Fig. 6 is a section on the line 6-6 of Fig. 3, showing pockets or holes for removably securing extra flints for use in the lighter and Fig. 7 is an enlarged side elevation of part of a preferred form of flint cutting wheel.

1 indicates a conventional form of adjustable table for the dental tools, etc. pivotally mounted on arms, 8', as shown, and arm 8 may be mounted upon the usual standard or support (not shown), through which the gas is supplied to the Bunsen, through burner tube 9, with air valve II, which regulates the mixture of air and gas by rotation of sleeve H), to expose or cover, more or less, port H, a predetermined amount. I2 is the gas orifice or burner and I3 is a cup-like guard and support surrounding the orifice and held on the burner as indicated at l4, l5.

The lighter standard is indicated at 16 and is provided with passage [1, for flint-wheel l8, rotatably mounted therein, upon shaft 19, having a square inner end 20, engaging a square hole in the wheel I8, and a round hole at 2| in the lighter standard I6, 22 indicating an annular recess or channel 22 in shaft 19 for ball 23, projected by compression spring 24, beneath threaded cap 46, to hold and lock said shaft while it engages wheel [8.

The standard N5 of the lighter may be provided with a rounded base projection IE, to rotatably engage hole 25, in the ring support 28, of the lighter and may be provided with diametrically opposed recesses or pockets 21, 28, for ball 29, projected by spring 30, in pocket 3|, with plug 3|, beneath ring 26, to permit standard l6 to be rotatated about and held in its adjusted position by ball 29, the housing 30' being fixed with relation to ring 26, and serving to retain the standard in its adjusted position, according to the seating of ball 29 in pocket 21 or 28. The periphery of wheel l8 may be out spirally and axially or transversely, as shown in Fig. 5, to provide cutters with radial walls 42 at the cutting sides and substantially tangential walls 43 at the trailing sides thereof, as shown.

In operation, the expansion ring 26, provided with radial cuts 31, is compressed when forced into the bottom of the cup-guard or support l3, where it is thus frictionally held when released. A flint 38 may then be taken from a reserve pocket 39, and after plunger 32 has been raised against spring 36 and turned by button 35 and seated in recess 40, a flint 38 is dropped into chute 35, where it comes to rest upon the exposed surface of flint-wheel l8 and is held by ofiset 34, as shown. By now turning on the gas at 45, then rotating the wheel 18, by turning the knurled finger piece 4|, sparks from the end of the flint l8 are discharged from the cutting surface of the wheel 18 in the path of the escaping gas, which is thereby ignited and this mode of operation follows, whether shaft l9 projects rightwardly or leftwardly from guard l3, the pockets 21, 28, and ball 29, serving to frictionally hold the lighter standard H5 in position according to the adjustment made.

Of course it will be understood that various modifications may be made in the construction without departing from the spirit of the invention, as claimed.

I claim:

1. In combination with a dentists lamp having the usual guard with a lateral opening through the side thereof, a lighter having a split ring base within, conforming to and frictionally engaging a bottom portion of said guard, a lighter standard thereon, a scratch-wheel and flint in said standard, and means extending through said opening for operating said lighter.

2. The lighter specified in parent claim 1, wherein said base comprises a split ring wider at the top than at the bottom.

3. The lighter specified in claim 1, having means for removably securing said standard upon said base.

4. The lighter specified in parent claim 1, havin flint feeding means comprising a resiliently projected plunger with an offset adapted to engage and feed said flint and means for releasing said plunger and flint for replacing the latter.

5. The lighter specified in parent claim 1, having resilient ball engaging means for rotatably engaging and for releasing said lighter operating means.

6. The lighter specified in parent claim 1, having resilient ball engaging means for holding and releasing said standard.
