SPECIFICATION forming part ofvLetters Patent N 0. 733,949, dated July 21, 1903. Application filed April 12 1902. Serial No. 102,527. (No model.)

To all whom it may concern.-

Be it known that 1, DANIEL DRAWBAUGH, a citizen of the United States, residing at Eberlys Mill, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Batteries,

of which the following is a specification.

This invention relates to an improved dry battery; and the main object of myinvention is the provision of a dry battery which is composed of materials which lessen the cost of manufacture of such batteries and which increase the life and efficiency thereof. These objects are attained by forming a dry battery, as herein set forth and more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central sectional View of a dry bat tery constructed according to and embodying my invention. Fig. 2 is a top plan view thereof; and Fig. 3 is a crosssection taken on line m m, Fig. 1.

Referring by letter to the drawings, A designates an outer cylinder or package made of zinc, this package having connected at one point on its upper edge a binding-post B, to which is made an electrical connection. Mounted in this cylinder in the center thereof is the flat stick 0, of carbon, which is preferably made in a flat form and has connected to its upper exterior end D the binding-post E, to which is connected the other electrical connection. Surrounding this carbon and contained in the cylinder is a composition F, of coke, plumbago, and a small quantity of plaster-of-paris, enough to form a paste, so that the carbon by means of its recesses G is securely held in the cylinder. Around this composition is placed a paper or other-porous material cylinder H, which forms a divisional wall between the composition and the alkali J, which is placed in the space between the cylinder Aand the cylinder H. This alkali is generally made of a composition of concentrated lye or caustic soda,with a small amount of plaster-of-paris to hold the composition in I have also used hydraulic cement in place of the plaster-of-paris and have found it to be an excellent substitute.

Placed within the cylinder A, surrounding the carbon-and'resting upon the parts F, H, and J, is a ring K of heavy paper, upon which is poured a layer L of melted pitch or tar to hermetically seal the package, and thus prevent the contents from becoming deteriorated from exposure to the outside elements.

Both of the compositions F and Jshonld be thoroughly mixed before being placed in the battery-form.

It is also evident that a battery constructed according to this invention is much cheaper, as the ingredients are cheaper, and that a more practical and efficient battery is produced.

'VVhat I claim as new, and desire to secure by Letters Patent, is-

1. A dry battery comprising an outer surrounding electrode, a central opposite electrode surrounded thereby, a composition of carbon, plumbago, and a plastic material surrounding the central electrode, and an alkali composition incased by the first-mentioned electrode and surrounding central electrode and the first-mentioned composition.

2. A dry battery, comprising an outer surrounding electrode, an excitant composition of alkali and a plastic material, a centrallyopposed electrode and a composition of carbon and plumbago surrounding said central electrode.

3. A dry battery, comprising an outer surrounding electrode, an excitant composition of an alkali, a centrally-opposed electrodeand a composition of carbon and plumbago surrounding the central electrode.

4. A dry battery, comprising an outer surrounding electrode, an excitant composition of an alkali and caustic potash, a centrally opposed electrode and a composition of carbon and plumbago surrounding said central electrode.

5. A dry battery, comprising an outer surrounding electrode, an' excitant composition of alkali and plaster-,of-paris, a centrally-opposed electrode and a composition of carbon and plumbago surrounding said central electrode.

6. A dry battery, comprising an outer surrounding electrode, an excitant of caustic potash and a plastic material, a centrally-opposed electrodeand a composition of carbon and plumbago surrounding said central elec trode.

'7. A dry battery, comprising an outer surrounding electrode, an excitant composition of potash and plaster-of-paris, a centrally-opposed electrode and a composition of carbon and plumbago surrounding said central electrode.

8. A dry battery, comprising an outer surrounding metallic cylinder, a stick of carbon surrounded thereby, a composition of carbon and plumbago surrounding said stick, and

an alkali surrounding the composition and the carbon stick and incased by the cylinder.

9. A dry battery, comprising an outer casing of zinc, an alkali excitant therein, a composition of coke, plumbago and a plastic material surrounded by the alkali, and an electrode mounted in the composition.

10. A dry battery, comprising an outer surrounding electrode, a porous cylinder mounted therein, an excitant made of an alkali and Witnesses:
