I Application filed March 4, 1918. Serial No. 220,386.

To all whom. it may concern Be it known that I, JOSEPH A. MOAULEY, a citizen of the United States ofAmerica, residing at 443 21st street,-.West New York, N. J have invented a new and useful taching Means for Removable Dentures, of which the following is a specification.

This invention dentures and the general objects of the invention are to provide simple, practical and thoroughly satisfactory means-for securing in place.

"A special obj ectof-the invention isto pro vide a form ofattaching means which will hold the dentures securely inplaceand which. at the same time will permit of the ready removal of the dentures.

In this connection it is the aim of my invention to provide a denture supporting or attaching means which can readily be adjusted to compensate for wear and to meet particular requirements. 1

Briefly stated, the invention comprises a base member, which isusually stationary, as by being secured fast to an abutment or the like, and an attaching member, which is usually carried by the denture and.'is constructed for engagement with the base member, said base member having an outstanding headed portion in the nature of a rail and the attaching member being'of tubular conformation to fit over said rail portion and having a flange or flanges .tobear upon the base member. frictional engagement with the base assist in holding the denture removably in place and furthermor provide a means bywhich the attaching member can readily be adjusted to fit it to the base.

Another feature of the invention is the provision of a special form of stop for limiting the engaging movement of the cooperating members and which can readily be adto meet different conditions.

A further feature is the slotting of the tubular attaching member on opposite sides thereof to provide localized sections which may be crimped together to exert a binding force upon the base member when the two members are assembled.

Other features of the invention and the details of construction will appear as the specification proceeds and will be made clear has reference to removable These flanges by their from consideration ofthe accompanying drawings-which illustrates the invention embodied in; practical commercial forms.

In said drawings- Figure 1, is abroken perspective view illustrating the invention. as applied to@ the mounting of a denture in the form of a bridge.

2' and: 3 are detail perspective views ofthe two coiiperating members of the device.

Fig. 4 is a cross sectional view of said members in assembled relation.

Figs. 5 and 6 are detail perspective views of the two cooperating members of a modified form of the device.

Flg. 7 is aplan view of said: engaged relation.

Fig. 8 is a longitudinal sectional view of the same substantially on the plane of line 8-8 of Fig. 7

Fig. 9 is 'a cross sectional view thereof substantially on the plane of line 9--9' of Fig. 8.

Fig. 1.0 is a view of the tubular sleeve member, looking at the open side thereof.

The base member of the device consists of asomewhat flattened base portion 5, which is usually slightly concaved at the back as indicated, to substantially fit thecurvatureof abutments or other element's-such as those indicated at 6- and 7 in Fig. 1, andan out standlng headed portion 8, in the nature of a rail, which a narrowed or reduced neck portion 9. This supporting head 8 is preferably formed" integrally with the base, the two being usually rolled as an integral piece of stock which is subsequently cut to proper lengths to fit the work in hand. i

The securing or attaching member is of generally tubular construction as indicated at 10, shaped to fit the supporting head relatlvely closely and open along one side as lndicated at 11 to permit ofsaid member belng slidably engaged longitudinally over the supporting head with a telescopic movement. This longitudinal slot or opening 11;, in the side of the tubular attaching member constitutes a throat receiving and closely members in fitting the neck 9 of the base member. Laterally outstanding longitudinally extending flanges 12 are shown provided at the opposite edges of the slot or opening in the side is connected with the base by,

' acte'r which the ting into the seat of the tubular attachingmember, said fianges in the illustration, frictlonally engaging the face of the base at opposite sides of the supporting head. In addition to providing this frictional engagement with the base member, these flanges reinforce the edge portions of the open-sided tubular attachin member and furthermore provide grips which may be readily engaged by a pair of pliers or the like for the purpose of adjusting the attaching member to the base menu her. It has been found that these fittings wear more or less with use and this wear may be compensated for by simply pinching together the opposite edges of the attaching member. These outstanding flanges provide a firm hold by which such edges may be gripped by a pair of pliers or the like, thereby facilitating the necessary adjustment and enabling the parts being maintained in effective engagement at all times. i In the second form of my invention illustrated in Figs. 5 to 10 the tubular attaching member is shown as slotted longitudinally at l3,on opposite sides thereof, just in rear of the outstanding flanges 12, to localize portions 14 at opposite edges of the throat in the side of the member, which can then be readily crimped or' pinched together more or less, as indicated at 15, to exert a certain binding tendency upon the base member. This construction 'enables the attaching member being adjusted to closely fit the base member intermediate its ends, while fitting the base member relatively loosely at the opposite ends thereof. This allows of a certain rocking motion corresponding more or less to the movement of this chartioning. As wear occurs it will be obvious that these localized sections at the edges of the attaching member may be easily adjusted to bring about a proper engagement of the two members.

Under certain conditions itis desirable to limit the engaging movement of the two members, for instance, in the case illustrated in Fig. 1, where it may be necessary to limit the movement of the denture toward the gum. In time however, the parts may recede, making it desirable to lower the denture farther toward the gum. The form of stop illustrated in Figs. 5, 7, 8 and 10 has been designed to meet such conditions and comprises a stop element 16 in the nature' of a bar at the upper end of the attaching member connecting opposite edge portions of said attaching member, this sto bar fit or recess 17 providbd in the top of the base member between the base and head portions thereof. ..The stop bar by its engagement with the bottom of this seat limits the movement of the denture toward the gum, but it it becomes necessary at any time to lower the denture this may be easily cal, square, or

natural teethhave'in 'funcrest nee accomplished-by cutting down the seat to the necessary extent. The seat isshown formed in the narrowest or neck portion of the base member, making the cutting down of the seat a simple matter. Another point about the seating or" the stop bar in a recess behind the head of the base member is, that this form of engagement has a tendency to cause the tubular attaching member to hug or be drawn more closely into engagement with said head portion. v

It will be apparent that the supporting post or base member may be made of elliptiangular shape in cross section instead ofthe circular form shown, the tubular attaching member in such case being made of corresponding shape so as to closely fit the same and it will be understood further that other changes may be made without departing from the true spirit and scope of the invention. My invention contemplates that the post member instead of being made of solid metal as shown, may be stamped to shape from sheet metal. This is less expensive and has other advantages in that the posts may be made more accurately to size and they possess a certain spring quality. A stamped sheet metal post further, has the advantage that by reason of the fact that it is hollow, and an instrument may be inserted therein to expand a portion thereof into frictional binding engagement with a particular portion of the tubular attaching member engaged thereon.

I claim;

1. Denture supporting means comprising, in combination, a headed supporting element and a tubular attaching element engageable thereover, said tubular attaching element being longitudinally slotted in opposite sides thereof and having portions adjacent the slots and separated by such slots from the body of the element crimped together to exert a binding efi'ect upon the headed supporting element.
