TOOL FOR POINTING MASON RY.

SPECIFICATION forming part of Letters Patent No. 443,387, dated December 23, 1890.

Application filed September 4, 1890. Serial No. 363,94 i. (Model) To all whom it may concern:

Be it known that I, J men A. BLANCHARD, of Duluth, in the county of St. Louis and State of Minnesota, have invented a new and Improved Tool for Pointing Masonry, of which the following is a full, clear, and exact description.

My invention relates to a tool for pointing masonry, and has for its object to provide a device commonly known as a jointer, simple and durable in construction, and especially adapted for masons and bricklayers use; also, to provide a means whereby the tool may be conveniently and effectually employed to impart to the mortar between the courses of brick or stone any desired facial contour.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation, partially in section, of a double pointer. Fig. 2 is abottom plan View of a single pointer. Fig. 3 is a transverse sectionon line on a: of Fig. 2, and Fig. 4 is a similar section illustrating a modification in the form of the heart of the tool in cross-section.

In the construction of a single pointer the body portion thereof consists of two metal side plates 10 of corresponding shape, the side pieces being of greater length than width.

The ends of the plates at their upper edges are chamfered or beveled, as illustrated at 11 in the drawings, whereby they may be reversed. In the construction of the plates their inner faces are usually straight] and their outer faces made to taper downward, as shown in the cross-section, Fig. 3. The plates are sharpest and thinnest at their lower edges, and are loosely united, preferably, by three studs or rivets 12, 13, and let, one rivet being located at the central portion of the plates and the other two near each end. The heads of the rivets may bear against the outer faces of the plates, or the plates may be countersunk around the openings receiving the rivets, in which event the heads of the latter are flush with the outer faces of the plates.

In locating the rivets the central rivet is slightly nearer the lower edges of the plates than the rivets at the ends. In fact, the line upon which the rivets are placed corresponds to the upper line of the plates. The rivets are of sufficient length to admit of the plates being forced a predetermined distance apart. In connection with the bodya handle 15 is employed, which handle is provided with an angular shank A, the horizontal member a of which shank is longest and is adapted to enter the space between the plates at their upper portion. The vertical member a of the shank is fitted to enter the handle 15, which may be of any approved construction. The horizontal member of the handle-shank is of a length corresponding to the length of the plates at their chamfered portions, and the said member of the shank is made wedgeshaped in cross-section, as illustrated in Figs. 3 and 4. The horizontal member of the handleshank is further provided in its under face at its ends with hook- like sockets 16 and 17, the opening of the socket 16 being horizontally located, while the opening of the socket 17 is vertically placed, as is best shown in Fig. 1. The socket 16 is adapted to receive one end rivet, and the socket 17 the opposite end rivet. The central portion of the shank is located above the central rivet 13.

In connection with the body what is termed a heart 18 is also employed. This heart consists of a metal strip of a length corresponding to the length of the plates at their lower edges and of awidth slightly greater than the space intervening the plates. The

under longitudinal face of the heart is of the same contour as the corresponding edges of the plates, and these edges may be straight or slightly convexed, as in practice may be found desirable.

In placing the parts together the heart is inserted between the plates, and the horizontal member of the handle-shank is introduced also between the plates at the upper edges of the same and forced downward, and by reason of the wedge shape in cross-section of the said shank member the plates are forced outward at the top, and consequently slightly inward at the bottom, thereby causing the plates to firmly clamp the heart and retain it securely in proper position. The horizontal shank member is introducet'l by causing one of the end rivets to enter the socket 10 of the shank member when the said member is in a vertical position, as indicated by dotted lines in Fig. 1. After the rivet is well seated in the socket lo the said shank member is forced downward between the plates until the opposite end rivet ll is seated in the socket 17.

I desire it to be distinctly understood that the heart may be of any desired shape in cr0ss-section-as, for instance, it may be llat, as shown in Fig. 3, in which event a flat or straight surface will be imparted to the mortar between the courses of brick or stone, or it may be V-shaped, as illustratet'l in Fig. at, by means of which a correspondingly angular surface will be imparted to the mortar, or the under surface of the heart may be cylind rical in cross-section, U-shaped, or may have any contour necessary to produce a desired impression upon the mortar.

In Fig. 1 I have illustrated what I term a double pointer, which consists of two bodysections faced in opposite directions, and the handle in this instance comprises only two horizontal shank members a, which extend from a Vertical central shank member a in opposite directions, each horizontal member of the shank being adapted to enter one body portion of the tool. The vertical shank member a of the handle is so shaped as to be conveniently held in the hand of the operator; but ordinarily one set of plates constitutes a handle for the manipulation of the opposite set, and one tool of the set is preferably made wider than the other in order to point a wide joint.

It is obvious that a tool constructed as above described may be expeditiously manipulated to impart any one of a number of impressions to the mortar, and that as the impression edges become worn the heart may be moved upward until it almost reaches the rivets 12, 1 3, and 1t, thus enabling an operator to eit'eetually use a tool for a maximum length of time.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture, a tool for pointing masonry or similar work, consisting of two opposed parallel plates loosely connected, a handle provided with a member \vedgeshaped in crossseetion and adapted to enter between the plates at one edge, and a heart adapted to be inserted between the plates at the opposite edge, substantially as shown and described.

2. In a tool for masons use, the combination, with opposed plates and rivets loosely uniting the plates, of a handle provided with a member wedge-shaped in cross-section and having sockets to receive the rivets, and a heart adapted to be inserted between the plates opposite the wedgeshaped member of the handle, as and for the purpose specified.

3. In a masons tool, the combination, with two opposed plates and rivets loosely con n ecting the said plates, of a handle provided with a member wedge-shaped in cross-section and adapted to be introduced between the plates at one edge, the said member being provided with an essentially longitudinal socket at one end and an essentially vertical socket at the other end, and a heart adapted to be introduced between the plates opposite the wedge member of the handle, whereby the said wedge member forces the plates to a firm engagement with the heart, as and for the pur pose set forth.
