Another object of the invention is to pro-' vide amounting having its electrical contacts arranged for more secure engagement with the terminals ofthe tube and less llable to become loosened andrendered inefiiclent 1 for the purpose required. c
Another object of the lnventlon is to pro- 7 vide a device in which the parts may be more quickly and conveniently assembled and are less liable. to become displaced or damaged in use.
Further objects set forth in the following specification which describes'a referred embodimentof the invention as ilustrated by the accome panying drawings. In the drawings:
Fig. 1 is a sectional view of the lmproved mounting, taken in the verticalplane of its axis on theline 11 of Fig. 2, and illus theivacuum tube showing its terminals trating a vacuum tube as-appl'ied thereto;
Fig. ,2, a plan view of the mount ng showing 1ts electrical contacts;
, Fig. 3, a similar view showing the ter s or plu s of the tube in section.

Fig. 4, a perspective ,view of the base of Fig. 5,-a view in perspective of the COlIlpletereceptacle or mount ng; and v Fig. 6, a perspeetive vlew of one of the contact-elements of the device.
Referring to the drawings, the preferred form of my invention as herein shown comprises a cylindrical block 201: insultating adapted to seatlagainst the.
material such as hard rubber, composition, fiber or the equivalent," At the center of the block 2 is a hole 3 for the insertion of a screw, bolt or other fastening element, the hem of'the screw 4 being received in a counter-bore 5. The'bottom of the block 2 is referably recessed at- (S-tOYiI Vide an annuihr rim 7 surrounding its erlphery and ase or other .support 9 to which the mounting is attached by means of the screw 4 Spaced around to be held in the mounting.
of the improvement are the axis of the block 2 are a plurality of prong-like terminals 12 'ject from the base of the vacuum 't-ubelfi i The tube or bulb 15 may be of any preferred type as usually employedainradio apparatus, and in its present form there are four terminals on its base. At the center of the base of the tube 15 is-a tapered projection 16 adapted to seat in the axialcounter-bore 5 of the block 2 to assist in centering the tube 'thereon. I
- In certain types of vacuum tubes the ter nnnal prongs or contacts at the base are made of different sizes tov proper placing of the tube inurelation to the respective contacts of the different electrical circuits with which connected. As herein shown, one terminal .13 is oflarger diameter than the other prongs 12, and one of the bores 11 of the block 2 is correspondingly larger than'the other bores 10... Due to this provision the tube 15 ,must invariably be placed in a certain definite relation to the contacts of the mounting "before its prongs can be entered :in the terminal will be engaged with its respective.contact of the several circuits of the electrical system. It: is. noted, however, thatin some types of vacuum tubestall of theiiterminal prongs are of the same size, .in which case the made-of uniform suitable indexing provide for thethe tube is to be.
bores tlferein so that each 'for registering the terminals with their re- Referringparticularly to Figs. 3 and cuttoa depth of" substantially one third the height or thickness of the block and are axlaptedkto receive the contact-fingers 20 which project therethrough .into the bores 10,and 11 to engage with the prongs 12 and 13 on the tube '15. y
The contact-fingers'20 are preferably constructed asstrips of sheet-metal forming portions-of arcuate shaped in detail in Fig. 6. s The plates 21 are adapted to conform to block '2 and their main. portion's22 arefasthe curved sides-0f the 'plates21, shown v the slit. 18 in the the'plate. The end three different parts, contact-plates 21, and
s I tened thereagainst by means of screws or studs 23 threadedinto tapped holes 2% in the block, seeFig. 1. The
against the block 2, while a finger-nut 26 on of the stud furnishes the hind the outer end ingmeans'for thewire 27. To form the contact-fingers 20 the plates 21 are slitted longitudinally at 28 and the metal in the finger or strip 20 thus cut away is left somewhat longer than the main port-ion of of the strip 20 is then bent inwardly in a radial direction to form the contact point 30 which projects through block 2 to engage with the prongs of the tube 15.
\eferring to Fig. 2 the fingers 20 are preferably sprung slightly outwardly away from the surface of the block 2 and their points 30 are of sufficient length to adapt them to enter some distance into the bore", and 11 in the block. When thetube is placed in position on the mounting 'by entering its prongs 12 and 13 in their respective bores 10 and 11 the rounded ends of the prongs will engage the ends of the contact-points and force the fingers 20 radially outward against their inherentspring tension. The fingers20 may be spring-tempered to insure their permanent resiliency whereby they maintain a firm pressure onthe sides ofthe tube terminals 12 and 13, and in this way a more secure and efficient electricalconnection is provided.
It will be observed from the above description that my invention provides an'extreniely simple, inexpensive fitting or mounting for the purpose specified. My improved mounting is small in compass and particularly neat in appearance. and comprises only the binding-posts 23, all of which are economical to manufacture and convenient to assemble, lug-for greater security of engagement between the several electrical contacts. The parts of the mounting are proof against damage or displacement andthe complete device is more durable in use and less llable to derangementthan similar devices heretofore employed in the art.
it is obvious that my improved mounting the central block 2,
besides provid-' mamas is adapted for various-uses as an electrical connector and may he applied to other purposes than that herein specified. Likewise, the construction and arrangement of the parts of the device may be varied without departing from the spirit or scope of the invention. Therefore, without limiting myself in thisrespect, I claim:
1. An electrical receptacle comprising a block of insulating-material provided with parallel holes for receiving the terminals of a vacuum'tube. said block having slits leading from its outer surface into the holes and extending longitudinally thereof, and strips of conducting-material fastened to the outside of. the block and provided, with spring fingers having their ends projecting through the slits and radially into the holes in the block.
V 2'. An electrical receptacle comprising a block of insulating-material provided with a plurality of parallel holes for the terminals of a vacuum tube, said block having slits cut through from its outer'surface and communicating with thelholes longitudinally thereof. and metal contact-elements fastened to the sides of the block and having portion": bent to project through the slits and radially into the holes toadapt them to engage with the terminals held therein.
3. An electrical receptacle comprising a block of insulating material provided with a plurality of parallel holes forrecciving the terminals of a vacuum tube, said block having slits cut through its sides to intersect the holes therein longitudinally thereof, and metal plates fastened to the sides of the block and formed with spring contact-fingers bent to project through the slits-to enter the holes radially thereof 4. An electrical mounting comprising a block of insulating material provided with "a plurality of holes for the terminals of a vacuum tube. and having slits leading from the sides of the block into the holes, sheetmetal plates fitted to and slitted to provide sprin -fingers having their terminals bent to pro ect through the slits into the holes in the block, and screws extending through the plates to fasten them to the sides of the block while also serving as binding-posts for the wiring connections.
In testimony whereof I afiix my signature.
