May 27, 1947- D. P. LAVIETES' SMOKER S P IPE Filed June 13, 1944 A 147 TOR/V5 Y Patented May 27, 1947 UNIT STATE OFFICE The invention relates to smokers pipes and more particularly to a pipe having a briar wood bowl and a push bit.

In the production of wood blocks from briar roots, the contour of these blocks from which stummels are made upon a irazing machine, has wide variation accordin to the number and size of blocks which can be cut from the same or from different roots. Because of irregularity in the size and shape of such roots, the operator of a cutting saw must exercise his judgment in order to produce as great a number of usable blocks from each root as is possible though such block may be suitable for different styles, sizes and shapes of pipe bowls. As a result blocks of many difierent sizes and shapes are cut from the same root and because of the necessity of having blocks of a size and shape to include in the stummel wood in sufficient quantity to provide not only the bowl proper but an integral stem, the percentage of wastage of material when cutting the blocks has been fairly high.

In smokers pipes, the integral stem lacks sufficient bulk to aiiord a suitable support for the removable bit and it has long been the practice, whether a screw or a push bit was used, to reinforce the end of the stem either by a metal band or a, metal fitting engageable by the bit, so that likelihood of splitting the stem and possibly the bowl from excessive stresses due to expansion of the wood of the stem from moisture drawn from the bowl with the smoke, or the tendency of a pipe smoker to exert excessive strength in applying the bit in an effort to secure a tight joint between the stem and the bit, is minimized.

Much of the wastage in cutting briar roots is in the form of blocks having dimensions which do not admit of their use in forming a stummel having an integral stem of sufiicient length to permit the usual practices to be followed in applying a bit thereto or provide adequate gripping area to enable the use of a reinforcing band or a metal fitting to resist crackin of the material and facilitate the application of a bit to the-bowl.

Prior to my invention, such small or oddly shaped blocks were customarily disposed of by using them as fuel in the furnace of the steam plant of a factory producing such blocks, and except for this use were a complete loss. They had no marketable value to pipe manufacturers.

To avoid such wastage of briar wood, I have produced a pipe having a bowl formed of such wood but lacking an integral stem so that the bit is applied directly to the bowl in a manner not only to ensure a tight, non-seeping, joint, but to secure such a joint without excessive pressure upon the bit. The construction of the pipe is uch as to provide sufiicient bulk of the hard wood of the bowl where it is engaged by the bit, to prevent possible cracking of the wood either from pressure developed when applying the bit or from. expansion of the wood when partially saturated with pitch, tar and other liquids accumulated in the bowl as a result of usage of the pipe.

The bit itself is made of material possessing some resiliency and when made of wood which is preferable, is of softer and more porous material than the briar wood of the bowl, and by reason of its bore, may have some degree of expansion without developing crackin stresses upon the bowl.

The socket communicating with the bowl and serving as a means of attachment of the bit, and one end portion of the push bit are so formed as to limit the expansion pressures which may be developed when applyin the bit and yet ensure a tight fit with movement of the bit inwardly of the socket even to a variable extent.

By utilizing what would otherwise be waste blocks of briar root in the production of pipes embodying the invention, I am enabled to produce pipes at a cost approximating that of the labor required in finishing the pipe, and the cost of the material of the bits, without sacrificing the quality of the finish, or the durability of the plpe.

The invention consists primarily in a smokers pipe embodying therein a briar wood bowl having a socket within the material of the Wall of, and communicating with the bore of the bowl and opening outwardly of said bowl, and a bit one end of which has a heady which conforms to and has a. close friction fit within said socket whereby crackin of the briar wood of the bowl from expansion thereof or cracking of the material of the bit due to excess pressure when applying the bit to a bowl, is prevented, and in such other features of construction as are hereinafter described and more particularly pointed out in the claims hereto appended.

Referring to the drawings,

' Fig. 1 is a side view of a smokers pipe embodying the invention with the lower part of the bowl broken away, and

Fig. 2 is a similar view with the bit positioned for application to the bowl, the end of the bit engageable with the bowl being broken away.

Like numerals refer to like parts in both of said views.

In the embodiment of the invention shown in the drawings, the bowl it is formed from a block ofbriar woodhaving the general form of a quadrangularprism, although a slight protuberance may be formed during frazing where the stem is to be applied thereto.

The bowl it] has the usual bore I! and within the wall of the bowl is a socket l2 one end of which communicates with a portion of the bore H ad jacent the bottom thereof and the other and larger end of which opens outwardly of the bowl. This socket has a cylindrical taper or is in truncated conical form with its largest diameter as 5 stated opening outwardly of the wall of the bowl. When as shown in the drawings, a protuberance as I3 is present, this materially increases the thickness of the wall of the bowl about said socket so as to permit a socket of considerable depth to be formed. and yet afford sufiicient bulk of material to resist cracking stresses from the bit. With this form of bowl, communication of the socket with the bore H may be through a short and small smoke opening Hi adjacent the bottom of the bore H.

Adapted to be attached to the bowl H! by means of the socket i2 is a push bit having at one end thereof a tapered cylindrical or truncated conical head it the outside graduated dimensions of which correspond with some portion of the graduated inside dimensions or the socket l2 so as to have a close friction fit within some part of said socket 12.

This construction permits the head of the bit-5. 7

to adapt itself to some part or said socket by a variable lengthwise movement of the bit until a tight joint is secured without the development of excessive pressure upon the bit. The length or depth of the socket i2 is greater than the length;

of the head 65 and the greatest diameter of the head is less than the greatest diameter of the socket so as to prevent said head from protruding beyond the outer wall of the bowl. The inner end of the socket is slightly smaller in diameter;

than the minimum diameter of the head, and the outer end of the socket is slightly larger than the maximum diameter of the head.

The portion it of the bit adjacent the portion of the head having the greatest diameter, is of;

making unnecessary the usual grinding operation in fitting a bit to a bowl in the factory.

By the use of an inwardly tapered socket l2 and a bit having a similarly tapered head I5, as described, any slight variance in dimensions of the socket or the head requires merely a difference in the endwise movement of the bit in order to secure a tight joint. With such a construction, no great nicety in the dimensions of the socket i2 and of the head 15 is required, since so long as the inner wall of the socket and the outer surface of said head have the same degree of angularity to the axis of the socket and the head, a tight fit of the bit is assured at some point of engagement with the wall of the socket.

Furthermore, any slight change of dimensions of the socket or of the head of the bit from heat or moisture, does not interfere with the fitting of the bit and the securing of a tight joint between the head i5 and the bowl of the pipe upon replacing the bit in the socket I2.

No reinforcements for the bowl or in the bit are used or required and since no metal fittings are used in connecting the bit with the bowl, a tight fit is assured not only because of the form of the socket and of the head 25, but because a more effective joint is secured by a wood to wood contact than with a metal to metal or a metal to Wood joint.

Bowls may vary widely in their general contour without affecting the results above referred to, and diiferent materials such as wood, horn, rubber or plastic may be used-for the bits within the limitations herein specified. An essential characteristic of the invention, however, is a di rect connection of the bit with the bowl so as to utilize the bulk of material in the bowl to resist cracking of the bowl from stresses developed in the use of the pipe or when applying a bit to the bowl.

Having described the invention, what I claim as new and desire to have protected by Letters Patent is:

1. A smokers pipe embodying therein a briar wood bowl having a bore and a tapered, truncated conical socket within the material of the wall of said bowl, said socket having its end of largest diameter opening outwardly of said bowl and the opposite end in communication with said bore, and a bit having a tapered, truncated conical head, the outer face of which has substantially the same degree of angularity as said socket and the greatest diameter of said head being less than the greatest diameter of said socket whereby said bit will adapt itself to some part of said socket to form a tight friction joint therewith and cracking of the briar wood of said bowl from expansion thereof or of the material of the bit, or from excess pressure when applying the bit to a bowl, is prevented.

2. A smokers pipe embodying therein a wooden bowl having a bore and a tapered, truncated conical socket within the material of the wall of said bowl, said socket having its end of largest diameter opening outwardly of said bowl and the opposite end in communication with said bore, and a bit having a tapered, truncated conical head of a. length less than the depth of said socket, the greatest diameter of said head bein less than the greatest diameter of said socket, the outer face of said head having substantially the same degree of angularity as said socket whereby said bit will adapt itself to some part of said socket to form a tight friction joint therewith and cracking of the wood of said bowl from expansion thereof or of the material of the bit, or from excess pressure when applying the bit to a bowl, is prevented. 7
