Patent AH-1888-L3922
From Otto-Lilienthal-Museum transcription and research:[1] The patent was either filed or approved on May 24, 1888. It was handwritten with 27 illustrations. "Source: k. k. Privilege Archive No. 38/2669" The invention is based on Gustav Lilienthal and concerns the so-called model kit, which can be regarded as a forerunner of the "erector set" (stable construction kit). The drawing set is identical to the similar German patent (id 60), with an eigefüge "p" for cardboard in Fig. 16."
Inferences from the text below: the patent was filed on May 24, 1888, not approved then. And the reference to Vienna below and the phrase "similar German patent" above suggests it could be a filing in Austria. The reference to L3922 could be a patent number but patents numbered 3922 in DE and AT are not Lilienthal's, and not aircraft-related. L3922 is not a syntactically acceptable patent number for the DPMA website. So despite all this detail we can't yet connect this patent information to a particular patent number.
However if it was a German patent, they are numbered in sequence and patents filed in April have numbers in the 44000s, so this one would be numbered around 45000. We don't have Austrian patents that far back and can't tell yet what number it would have if it's Austrian.
Hypothesis: It's an Austrian patent, supplementary to a German patent already filed, and they were not numbered at this time? But then, why can't we at least identify the German parent patent?
The Lilenthal museum staffer, probably named Seifert, transcribed this patent's text and typed it up in an online pdf. Here's a google translate of that to English, with paraphrasing and slimming and simplifying by User:Econterms:

- Apparatus and methods for making model buildings
- by Otto Lilienthal from Gross-Lichterfelde [neighborhood of] Berlin
The invention produces from readily available assembled and disassembled materials which can serve both as a model and as an instructive and interesting toy in varied ways. The materials fit into a small room. The buildings made with them are light and transportable, can be easily taken apart and the material can be used again. The accompanying drawings show on Sheet I, Figs. 1-13, the most varied combinations of material; Figs. 14-26 the individual parts of the material; Sheet II Fig. 27 shows the model of a collapsible house with omission of the panels to be inserted between the slats. The material for the model constructions to be made consists of strips (Figures 14 and 15) of the profile a of different lengths shown in Figure 16, which are uniformly pierced at regular intervals. These strips are connected by means of needles (Figs.18-24a) in a variety of ways, depending on the required purpose. as shown in FIGS. 1-13 and 27 show. The needles are fastened by pre-inserted wedges C. Fig. 17. Fig. 25 shows a sheet metal bracket which serves as a diagonal strut, Fig. 26 shows the fastening of the roof frame also made of sheet metal. Rafters or other obliquely running connection parts are fastened by the curved cotter pins Fig. 24 24a. As can be seen in FIGS. 13-24, the splint needles have different lengths, which depend on the number of strips to be joined; they have to protrude far enough to allow a wedge C (FIG. 17) to be pushed through for holding. For a more detailed explanation of Figs. 1-13 serve as follows: To extend a rod one uses the compound Fig. 2. Fig. 1 shows how the Strips at a right angle to each other, as well as Fig. 5 and 7; in Fig. 1 straight needles (Figures 17 and 20); in Fig. 5, a crooked needle (Figs. 24, 24a) is used; in Fig. 7, two needles (Fig. 18) are used, of which those of the lower rod are passed through the upper one, and secured by wedge. In Fig. 13, the upper bar comes out against the lower [3] on the outside by one bar width, the needle of the upper bar is on the outside of the lower, and the needle of the lower bar is inserted from inside to outside through the other needle , In Fig. 11, the needle of the upper rod (Fig. 19 or 20]) is inserted through the needle of the lower rod (Fig. 18), and through this the wedge. In the compounds Fig. 8 u.9 they are inserted crosswise and just appropriate so that they go through each other, as well as in Fig. 12, where wedges by the superimposed rods are pulled together. Fig. 10 shows a simple corner connection with needles (Fig. 18), which go through on the inside and are fastened by wedges. If, as in FIG. 6, a wagerechter bar is still to be connected to the corner, then needles (FIG. 19) are used in the same way as with shorter needles in FIG. Figure 4 shows the attachment of the rafters or similar slanting woods. The crooked needles (FIGS. 24, 24a) are used for this purpose. The timbers on which the rafters rest are called Rähme, the upper of the Firsträhm, the lower the Wandrähm. The firestop is located in the metal fork (Figure 26) which is attached to the bar behind with needles (Figure 18) The metal brackets (Figure 25) are also secured with needles (Figure 18) The holes in the bars must be so be large that two needles can pass through, which is necessary for the Firsträhmen Firsträhmen for attachment of the rafters, it is a crooked needle (Fig. 24, 24a) from the right and the like from the left through Angle is fixed at a position of Wandrähms where a rafter is to rest, put a straight needle (Fig. 18) between the crooked needle (Fig.24, 24a), as shown in Fig. 3 at z Panels located on the sides of the bars may be slid between each two bars of panels (made of cardboard or similar material), as shown in Figure 16. Apparatus and methods for making model structures of bars of various lengths which are arranged in a uniform manner ß long Längenheilheilung are often perforated and are connected by means of straight or curved V-shaped sapwood pins and associated wedges, while the surface filling is effected by inserting plates in the laterally attached to the strips Nuthen. Vienna on May 24, 1888.- [signed]
